Top SaaS Companies Software Buyers Are Contracting With

‍

The top SaaS companies business buyers contract with include Salesforce, DocuSign, Zoom, Adobe, Atlassian, GitHub, Slack, Okta, Microsoft and Datadog, plus about 15 other vendors that recur in business renewal calendars.

If you own renewals, you already know these names. Your calendar holds the same 20 to 30 vendors every year. The harder thing to find is a neutral source that explains how each one prices and what tends to happen when the contract comes up for renewal.

This SaaS companies list covers 25 leading SaaS companies, grouped by the budget lines businesses actually spend on. Each entry gives you the pricing model, typical renewal behavior and a before-you-sign check. Market-cap rankings, founding dates and startup directories are left out, because none of them help you negotiate with enterprise SaaS companies.

The notes reflect patterns in Tropic's SaaS market intelligence across $23B+ in spend under management, so they come from contract data instead of vendor marketing.

How This List Was Built

This SaaS companies list includes the top SaaS companies that show up repeatedly in business spend across finance, IT, procurement and revenue teams. Each one is grouped by the budget line it usually sits in, so you can jump straight to the category you're planning for.

The patterns behind each note come from Tropic's SaaS market intelligence, built on $23B+ in spend under management. Uplift figures and renewal patterns come from Tropic's negotiation playbooks and contract data. They describe what buyers commonly see, so confirm them against your own agreement.

Every entry follows the same format. You get one line on what the vendor is, how it prices, what tends to happen at renewal and what to check before signing. For the full mechanics behind those checks, see our guide to negotiating SaaS contracts and our SaaS contract negotiation checklist.

What 'Top' Means to a Buyer

Here, "top" means share of business spend and how often a vendor appears in contracts. The best SaaS companies for this list are the ones you're most likely to be renewing this year. Startups and early-stage vendors are deliberately left off.

The Three Checks Behind Every Entry

• Pricing model: Know what drives the bill: per user, per module, consumption or tiered. The driver determines where cost creeps in between signing and renewal.
• Renewal mechanics: Check the term length, the auto-renew notice window and the uplift clause. Most room to negotiate disappears once the notice window closes.
• Benchmarking: Compare the quote against what comparable buyers pay. A list price tells you where the vendor starts. A benchmark tells you where deals actually land.

CRM, Sales and Revenue Tools

These top B2B SaaS companies are clear examples of SaaS companies that price on more than seats, with add-ons, usage charges, credits, platform fees and volume tiers on top. Across these enterprise SaaS companies, Tropic's playbooks show stated uplifts, in Gong's case even on flat seats, and seat cuts often raise per-seat rates or reduce discounts. Settle any changes before the auto-renewal notice window closes, and plan seat additions for renewal where discounts depend on it, as they do at LinkedIn Sales Navigator.

Salesforce

Salesforce is a sales and service CRM with marketing, commerce, analytics and AI products.

• Pricing model: Per-user licenses, add-ons charged as a percentage of contract value and usage charges such as storage and API calls, sometimes on separate order forms.
• At renewal: Tropic's playbook rates renewals as challenging and identifies a standard 9% uplift. Reducing licenses can raise the per-license rate.
• Before you sign: Compare purchased, provisioned and active licenses. Get an uplift cap, future-license rates and swap rights on the order form.

HubSpot

HubSpot is a CRM and marketing automation tool for sales, service and marketing teams.

• Pricing model: Products and tiers, seats and, for Marketing Hub, contact volume. The newer seat model and HubSpot Credits can change the cost of access and of AI or data-enrichment usage. See HubSpot pricing.
• At renewal: Commonly negotiable, though discounts may shrink when volume drops. The first renewal after a move to the seat model may carry a negotiable 5% uplift.
• Before you sign: Verify seat types, contact allowance, included credits and onboarding fees, and document any price protection.

ZoomInfo

ZoomInfo is a B2B sales and marketing data provider for prospecting and data enrichment.

• Pricing model: SalesOS tiers include seats and bulk data credits. Extra users, credits and features such as Chorus or support can be priced separately. See ZoomInfo pricing.
• At renewal: Often flexible, especially when you show budget limits, underused capacity or a credible alternative. Check the auto-renewal notice requirement early.
• Before you sign: Compare billed seats and credits with actual use, then remove or downgrade what you don't need.

Gong

Gong is a revenue intelligence tool that records customer interactions to support deal analysis, coaching and forecasting.

• Pricing model: A platform fee plus per-user licenses, with Foundation as the base and modules such as Enable and Forecast Essentials sold separately or bundled. Packaging has changed, so check which modules a quote includes. See Gong pricing.
• At renewal: Tropic's playbook shows Gong may propose a 5 to 7% increase on flat seats, and seat cuts can raise the per-seat price. Finalize changes at least 30 days before renewal.
• Before you sign: Confirm active users, required modules, the platform fee and how mid-term seats are treated.

LinkedIn Sales Navigator

LinkedIn Sales Navigator is LinkedIn's prospecting and lead-research tool for sales teams.

• Pricing model: Priced per license per year, with rates tiered by license volume. Advanced is generally about 7 to 10% less than Advanced Plus, which adds CRM integration with Salesforce and Dynamics.
• At renewal: Tropic's playbook shows discounted additional seats generally need to be bought at renewal instead of mid-term. SMB All In and SSEP arrangements generally cover the full sales team and may require a multi-year term with built-in growth or buffer seats.
• Before you sign: Confirm whether you need CRM integration and validate your seat count against the volume tier. Tropic's playbook hasn't seen Advanced Plus offered below 10 seats.

Collaboration and Productivity Suites

These leading SaaS companies are among the most popular in business spend, and Microsoft and Google, two of the largest SaaS companies, appear on most buyer-side lists of the top 10 SaaS companies. Most price per user, with annual plans that cost less but lock in a minimum user count. Reducing seats is where these renewals commonly get expensive, through lost discounts or higher unit rates.

Know your active user count before the notice window. For day-to-day seat visibility, that typically sits with a SaaS management solution.

Microsoft 365

Microsoft 365 is Microsoft's subscription productivity suite, combining Office apps with business email, file storage and collaboration tools.

• Pricing model: Per user, per month across tiers such as Office 365 E1, E3 and E5 and Microsoft 365 Business Basic, Standard and Premium. Annual commitments generally cost less than month-to-month but set your starting user count as a minimum.
• At renewal: Tropic's playbook rates renewals as challenging. Reducing users can remove discounts, and reseller terms can differ from direct terms.
• Before you sign: Confirm the tier, whether Teams is included, committed seats and add-on costs such as Copilot. Ask resellers to separate Microsoft's discount from their own.

Google Workspace

Google Workspace is Google's business email, meetings and storage suite.

• Pricing model: Per user by tier. Annual commitments fix a minimum user count, while the Flex plan costs more but lets usage move.
• At renewal: Commonly challenging to negotiate. Reducing users can remove discounts, and a late renewal can put the account on Flex pricing.
• Before you sign: Confirm the tier, committed users and added-user price. Ask resellers to separate their discount from Google's.

Slack

Slack is a workplace messaging tool for teams inside and outside an organization.

• Pricing model: Per user across Pro, Business+ and Enterprise+, with AI features now included in the upper tiers. See Slack pricing.
• At renewal: Often flexible, but Tropic's playbook shows a typical 9% annual uplift, and Slack may push for quarterly seat true-ups.
• Before you sign: Verify active seats and request an annual increase cap. The playbook suggests targeting 3 to 5%, and multi-year terms should include a rate benefit.

Zoom

Zoom is a video communications company best known for online meetings, with phone, webinar and room products.

• Pricing model: Per user or per host, with separate products such as webinar hosts and phone lines. Annual plans generally cost less than monthly but lock in starting usage.
• At renewal: Commonly negotiable, though seat cuts may raise the per-unit rate. Tropic's playbook says to send any opt-out notice more than 30 days before renewal.
• Before you sign: Match licenses and add-ons such as Webinars and Rooms to actual use, and check any Named Host to Zoom Workplace migration.

AI Models and Assistants

AI contracts combine seat fees with consumption, which makes spend harder to predict than a flat seat count. OpenAI and Anthropic both sell seat-based team plans, but their enterprise models separate the seat fee from credit- or token-based usage, and API usage is priced by tokens. The renewal risk sits in the usage forecast and in what happens once a commitment runs out. Tropic's playbooks rate OpenAI as challenging to negotiate and Anthropic as reasonably negotiable. Model seats and expected usage together, and set spending limits before you commit. For a category-by-category playbook, see how to manage AI costs.

OpenAI

OpenAI is an AI company that sells enterprise chat, coding and API services, including ChatGPT.

• Pricing model: Business plans are seat-based. The newer Enterprise + Codex model separates a seat fee from credit-based consumption, while an older Enterprise model bundles pooled credits with seats. API usage is priced by tokens.
• At renewal: Tropic's playbook rates both new business and renewals as challenging. The newer packaging can change renewal economics substantially, especially if you're moving off pooled credits.
• Before you sign: Model expected credits and API usage against both structures, and compare total cost instead of the seat rate alone. Confirm the minimum commitment, rates after the credit pool runs out and admin controls for limiting overages.

Anthropic

Anthropic is an AI company that sells chat, coding and API services, including Claude.

• Pricing model: Team plans are seat-based with usage limits. Enterprise separates the seat fee from token-based consumption, with no usage bundled into the seat. API commitments may offer discounted rates.
• At renewal: Tropic's playbook rates renewals as reasonably negotiable and new business as flexible. A commitment may help reduce Enterprise seat fees, but an API discount isn't automatic and ends once the committed amount is consumed.
• Before you sign: Forecast token usage as well as seats, confirm what happens when the commitment runs out and set organization-level and per-user spending limits. Compare a commitment's total cost with pay-as-you-go.

Data, Analytics and Cloud Infrastructure

Snowflake, Datadog and MongoDB, some of the biggest SaaS companies in data and cloud, price on usage. You either pay as you go or commit to compute, usage metrics or resource consumption at a discount, which makes these clear examples of SaaS companies where cost follows consumption. The renewal risk sits in the commit: unused commitments can be forfeited, and shrinking a commit can raise unit rates.

Read more about usage-based pricing models and consumption-based pricing. Tropic's pricing intelligence covers commit structures and discount tiers on these vendors, so you can size the commit with comparable contract data.

Snowflake

Snowflake is a cloud data warehousing and analytics service.

• Pricing model: Consumption-based compute and storage, discounted by committed usage and service tier.
• At renewal: Commonly negotiable. Unused capacity rolls over only if the renewal value at least matches the prior commitment, so a lower renewal can forfeit credits.
• Before you sign: Forecast conservatively and confirm the tier, commitment and rollover conditions.

Datadog

Datadog is a cloud observability vendor for engineering and IT teams.

• Pricing model: Discounted commitments on usage metrics such as hosts, logs, traces and tests, plus on-demand charges above them. Larger accounts may qualify for a drawdown agreement.
• At renewal: Commonly negotiable. Start 60 to 90 days out with recent usage data, and avoid growth commitments above your forecast.
• Before you sign: Check each SKU's commit and on-demand rate, and ask to waive any uplift for quarterly billing.

MongoDB

MongoDB is a database company whose cloud service stores and queries data for applications.

• Pricing model: Pay-as-you-go charges for storage, data transfer and query processing, with rates that can vary by cloud provider and region. An upfront consumption commitment earns volume discounts.
• At renewal: Tropic's playbook rates renewals as very challenging. Reducing a commitment commonly brings pressure to raise the unit rate, so start early.
• Before you sign: Check your forecast and regional rates, and have procurement review any prepaid structure.

Security and Identity

Security and identity vendors are some of the harder enterprise SaaS companies to renegotiate on this list. Tropic's playbooks rate Okta and 1Password renewals as challenging, and a flat seat count doesn't protect your prior terms: Okta anticipates increases on flat renewals, and 1Password may not preserve the prior discount. KnowBe4 is more willing to negotiate, though it may reduce an initial discount and raise per-user rates when seat counts fall. Before you accept any proposal from these top B2B SaaS companies, check whether the price beats the benchmark for the tiers and products you actually use, using a price benchmarking view of what comparable buyers pay.

Okta

Okta is a workforce identity provider for sign-on, authentication and access management.

• Pricing model: Per user or per employee, through suites or individual products. Support is a mandatory charge based on SaaS fees.
• At renewal: Tropic's guidance rates renewals as challenging and anticipates increases on flat renewals. Agreements typically carry a 30-day auto-renewal notice.
• Before you sign: Confirm active users, support and sandbox charges, and get written protection against renewal increases.

1Password

1Password is a password management company for businesses and teams.

• Pricing model: The Business plan is priced per user per month on an annual agreement, with volume-based discounts.
• At renewal: Tropic's playbook rates renewals as challenging. Reducing users can reduce your discount, and even a flat seat count may not preserve the prior discount.
• Before you sign: Audit active users, and compare the proposed per-user rate and discount with your current agreement.

KnowBe4

KnowBe4 is a security awareness training company. Its core KMSAT product is sold alongside PhishER, Compliance Plus, Security Coach and AIDA.

• Pricing model: KMSAT comes in Silver, Gold, Platinum and Diamond tiers, priced per user per month by tier and user-volume band. Additional products are purchased separately.
• At renewal: Commonly negotiable, though KnowBe4 may reduce or remove an initial discount. Tropic's playbook also notes periodic list-price increases of 10 to 20% and higher per-user rates when seat counts fall.
• Before you sign: Compare active users with the quoted count, and request pricing for the tiers you actually need instead of defaulting to Diamond. Check each add-on's cost and whether your discount carries forward.

Developer, IT and Support Tools

Engineering, IT and support teams often own contracts with these top SaaS companies, so procurement tends to see them last. Several reprice on their own schedule: GitHub reviews discounts every year, Atlassian typically raises prices around September to October, Zendesk may push existing customers toward current list prices and Cloudflare carries a typical 7 to 10% annual uplift. Pricing ranges from per-seat and per-agent licensing to bundled monthly fees. Get each renewal onto the calendar before the notice window. SaaS renewal management gives these contracts the same lead time as the rest of your stack, and these vendors round out any list of the top 10 SaaS companies technical teams depend on.

GitHub

GitHub is Microsoft's code hosting and collaboration service for engineering teams.

• Pricing model: Per-seat Enterprise, active-committer Advanced Security and per-user Copilot plans, with metered credits on some products.
• At renewal: Tropic's playbook rates renewals as challenging. Discounts are reviewed annually instead of carried forward, and may shrink when seats fall.
• Before you sign: Check seats against active users and committers, and whether prepaid credits expire unused.

Atlassian

Atlassian makes team collaboration and work-management tools, including Jira for project tracking and Confluence for documentation.

• Pricing model: Direct purchases are generally at published prices. Resellers may discount, and annual or multi-year reseller deals generally use fixed seat-count buckets.
• At renewal: Direct renewals are commonly challenging, and Tropic's playbook notes annual price increases around September to October.
• Before you sign: Audit active users, check whether a seat bucket forces extra licenses and compare reseller quotes.

Zendesk

Zendesk is a customer service company whose Support and Suite plans help teams manage customer requests.

• Pricing model: Core plans are generally priced per agent per month, with separate add-ons. Pooled and enterprise agreement models may also be available.
• At renewal: Tropic's playbook rates renewals as challenging, and Zendesk may try to move existing customers toward current list prices. Give notice of any reductions or downgrades at least 30 days before contract end.
• Before you sign: Verify active agents, required add-ons, retained discounts and auto-renewal terms. Zendesk tends to push for annual payment, so request quarterly billing if you prefer it.

Cloudflare

Cloudflare is a network services company that keeps websites and applications secure, fast and reliable, with CDN, DDoS protection and web application firewall products.

• Pricing model: Commonly one monthly fee covering multiple products and committed volumes, and usage caps can be tied to data volume or requests. Enterprise deals may draw from a shared pool of funds.
• At renewal: Often flexible, but Tropic's playbook shows a typical 7 to 10% annual uplift and a 60-day opt-out window. Renewal paperwork may show only incremental add-on charges.
• Before you sign: Request the full agreement value with a product-by-product breakdown, and check caps and overage terms.

Finance, Contracts and Creative Suites

Three of these top SaaS companies, DocuSign, Adobe and NetSuite, are commonly challenging to negotiate at renewal, and reducing your footprint with them carries its own risk. Avalara is more negotiable, but its tiered pricing means growing past a tier can cost you too. Before you sign year one, get the year-two price in writing, along with renewal increases, caps and minimums. Our SaaS contract negotiation checklist covers the terms to lock in.

DocuSign

DocuSign is an e-signature and agreement management service.

• Pricing model: User-based or envelope-based contracts, plus user-based Intelligent Agreement Management (IAM) plans. Support tiers and overage charges can add to the cost.
• At renewal: Tropic's playbook shows DocuSign typically seeks 7 to 10% annual increases and may offer incentives to move to IAM or renew early.
• Before you sign: Compare user and envelope costs against actual use, and get overage rates and renewal increases in writing.

Adobe

Adobe makes creative and document tools, including Creative Cloud design apps and Acrobat for PDFs and e-signatures.

• Pricing model: Per-application-seat licensing with volume discounts across products. Three-year commitments can add price protection.
• At renewal: Commonly challenging. The license count you renew becomes the minimum commitment for the term, so unused seats get costly.
• Before you sign: Audit active seats, check whether an All Apps license is warranted and compare direct and reseller quotes.

NetSuite

NetSuite is Oracle's cloud ERP system for running finance and operations.

• Pricing model: Individually priced SKUs. The base edition depends partly on General Access (GA) users, and support, sandbox and other services can add to the total.
• At renewal: NetSuite may open with a substantial increase, so Tropic's guidance recommends starting 4 to 6 months early. Reducing licenses or modules can void an existing cap or discount.
• Before you sign: Verify GA-user counts and check exactly which charges a renewal cap covers. Standard payment terms are quarterly, Net 30.

Avalara

Avalara is a tax compliance company offering automated tax calculation through AvaTax and managed returns services.

• Pricing model: AvaTax is priced by transaction-volume tier instead of per transaction. Managed returns also use tiers, with returns calculated individually.
• At renewal: Commonly negotiable. Tropic's playbook notes a 5% increase in 2025 that appears to continue into 2026.
• Before you sign: Forecast transactions and returns against the proposed tiers. Crossing a tier by even one transaction can trigger an auto-upgrade fee and higher tier cost, so compare that with the overage charge and opt out if it makes sense.

These patterns repeat across every category in this SaaS companies list: per-user pricing, auto-renewal, uplift clauses, commits and volume tiers. Once you know which one drives a contract, you know which check to run.

You walk into the renewal with a benchmark instead of a list price. Explore Tropic's SaaS market intelligence.
• Contract and renewal visibility: Every vendor on this list sits in one renewal calendar, with notice windows, uplift clauses and auto-renew dates surfaced ahead of time. Engineering-owned and finance-owned contracts get the same lead time. Learn more about SaaS renewal management.
• Negotiation support: Tropic's negotiation expertise and benchmarks have delivered $425M+ in savings across contracts with vendors like these. The before-you-sign checks above are the questions that work is built on. See our guide to negotiating SaaS contracts and our SaaS contract negotiation checklist.

Know the Contract, Not Just the Company

The top SaaS companies are familiar names, but their contracts aren't interchangeable. Per-user, consumption and module pricing each need a different pre-renewal check, and each vendor on this list has its own renewal pattern.

Before you sign with any of them, confirm four things: the pricing model, the auto-renewal notice window, the uplift cap and a benchmark from comparable contracts. Start early on the vendors Tropic's playbooks rate as challenging, and settle seat or commit changes before the notice window closes. Tropic's $23B+ in spend data is where those benchmarks come from.

FAQs: Top SaaS Companies

What are the top SaaS companies businesses buy from?

The SaaS companies that appear most often in business contracts include Salesforce, DocuSign, Zoom, Adobe, Atlassian, GitHub, Slack, Okta, Microsoft and Datadog, grouped across CRM, collaboration, AI, data, security, developer and support tools, and finance. Which vendors matter to you depends on the spend category, which is why this list is organized by budget line rather than by company size.

What is the biggest SaaS company?

By revenue and market value, Microsoft and Salesforce are usually cited as the largest pure or near-pure SaaS vendors, with Adobe, Oracle and ServiceNow close behind [writer to source: 2026 revenue or market-cap figures from filings]. For a buyer, size matters less than how the vendor prices and renews, which is what the vendor notes in this list cover.

How do most top SaaS companies price their products?

Most sell annual or multi-year per-user subscriptions with tiered editions, and many add module or add-on pricing on top. Data, infrastructure and AI vendors such as Snowflake, MongoDB and OpenAI price on consumption with committed-spend discounts, which changes the renewal risk from unused seats to unused commits.

What should I check before renewing with a top SaaS vendor?

Confirm four things: the pricing model and what drives the bill, the auto-renewal notice window, the uplift clause and any cap on it, and a benchmark from comparable contracts. Tropic's pricing intelligence across $23B+ in spend under management gives buyers that benchmark before the renewal conversation starts.

What are the top 10 SaaS companies?

Lists vary by how you measure. Based on adoption, measured as contract count in Tropic's data, a buyer-side top 10 would include Salesforce, DocuSign, Zoom, Adobe, Atlassian, GitHub, Slack, Okta, Microsoft and Datadog. Investor lists ranked by market cap and job-seeker lists ranked by hiring will look different.

Is anything replacing SaaS?

SaaS is not being replaced, but its pricing is shifting: more vendors are adding consumption and AI add-on pricing alongside per-user seats, and agent-based features are being priced separately. AI vendors such as OpenAI and Anthropic already combine seat fees with credit- or token-based usage, and Tropic's guide on how to manage AI costs covers how to budget for it. For buyers that means contracts are getting more variable, and the pre-renewal checks in this list matter more, not less.
