SaaS — Software as a Service — has eaten the world. Every industry, from banking to farming, now runs on subscription software. The global SaaS market is projected to surpass $700 billion by 2028, and there are now over 30,000 SaaS companies worldwide.
But here's the thing: not all SaaS is the same. A $5/month note-taking app and a $500K/year enterprise security platform are both "SaaS" — but their business models, customers, and growth strategies are radically different.
This guide walks through 35+ real SaaS examples, organized by category, with breakdowns of what makes each one tick. Whether you're researching competitors, looking for inspiration, or studying what makes a SaaS business work, these examples will give you a clear picture of the landscape.
What Is SaaS?
SaaS (Software as a Service) is software delivered over the internet, paid for on a subscription basis, rather than installed locally or purchased with a one-time license. Instead of buying Microsoft Office on a CD in 2005, you subscribe to Microsoft 365 for $6.99/month. Instead of installing Salesforce from a server rack, you log in through your browser.
The defining characteristics of SaaS:
- Subscription pricing — monthly or annual recurring revenue (MRR/ARR)
- Cloud-hosted — no installation, no servers to manage
- Automatic updates — new features appear without you doing anything
- Accessible anywhere — browser, mobile, or desktop app
- Multi-tenant architecture — one codebase serves all customers
The SaaS model is powerful because it aligns incentives: the company only keeps making money if the product keeps delivering value. Unlike traditional software where the vendor gets paid upfront and has little reason to improve the product, SaaS companies live and die by retention.
B2B SaaS Examples (Business-to-Business)
B2B SaaS companies sell to other businesses. They're the largest and most valuable segment of the SaaS market. Companies will happily pay $10K+/year for software that saves them $100K in labor — which is why B2B SaaS has some of the highest valuations in tech.
Horizontal B2B SaaS (Used Across Industries)
These tools serve any business regardless of industry.
Salesforce — The original SaaS giant. Founded in 1999, Salesforce pioneered cloud CRM and proved the SaaS model could work at enterprise scale. Today it's a $200B+ company with products spanning sales, marketing, service, and analytics. The core insight: every company needs to manage customer relationships, and doing it in the cloud is better than on-premise.
Slack — Workplace messaging that replaced internal email for millions of teams. Slack's genius wasn't the chat itself — it was the integrations. By connecting to GitHub, Jira, Google Drive, and 2,000+ other tools, Slack became the central nervous system of modern companies. Acquired by Salesforce for $27.7B in 2021.
Notion — All-in-one workspace blending docs, wikis, databases, and project management. Notion's strength is flexibility: a startup might use it as their entire company wiki while a solo freelancer uses it as a personal CRM. This horizontal appeal gives Notion a massive addressable market.
Figma — Browser-based design tool that ate Adobe's lunch by making design collaborative. Multiple designers can work on the same file simultaneously, like Google Docs for UI design. Figma proved that even complex creative software can work beautifully in the browser.
Stripe — Payment infrastructure for the internet. Developers integrate Stripe's API in a few lines of code and instantly accept payments from anywhere in the world. Stripe's brilliance was targeting developers first — they became the default choice for every new startup, which forced enterprises to adopt them too. (Read more in our FinTech startup directory.)
B2B SaaS by Function
HR & Payroll: Rippling and Deel represent the modern wave of HR & Productivity SaaS. Rippling unifies HR, IT, and finance — onboard an employee and they automatically get device provisioning, app access, payroll setup, and benefits enrollment. Deel tackled the harder problem of global hiring: compliantly employ anyone in 150+ countries without setting up local entities.
Developer Tools: Supabase (open-source Firebase alternative), Vercel (frontend deployment platform), and Replit (browser-based coding environment) are Developer Tools SaaS companies that sell to engineers. The DevTools playbook: make the free tier so good that individual developers adopt it, then sell team/enterprise plans to their companies.
Design & Creative: Canva democratized graphic design — 150 million monthly users create presentations, social media graphics, and marketing materials with drag-and-drop simplicity. Canva proved you don't need to target professional designers; the much bigger market is everyone else who occasionally needs to make something look good. The Creative & Design Tools space continues to expand with AI-native entrants.
Cybersecurity: Antigen and other Cybersecurity SaaS companies sell security as a subscription — continuous monitoring, threat detection, and compliance management delivered through the cloud. Cybersecurity SaaS is uniquely sticky: once a company builds their security posture around a platform, switching costs are enormous.
Vertical SaaS Examples (Industry-Specific)
Vertical SaaS targets a specific industry with tailored software. These companies often have smaller total addressable markets than horizontal SaaS, but they win by going deep — building the exact features that one industry needs, which generalist tools can't replicate.
Procore — Construction management software. Building a skyscraper involves hundreds of contractors, thousands of documents, and millions of moving parts. Procore brings it all into one platform: project management, quality and safety, design coordination, and financials. Public company worth $10B+.
Toast — Restaurant point-of-sale and management platform. Toast started as a consumer payments app, pivoted to restaurant POS, and now serves 100,000+ restaurants with everything from order management to payroll to loyalty programs. The hardware+software bundle creates a deep moat — replacing Toast means buying new terminals, retraining staff, and migrating years of data.
Veeva Systems — Cloud software for the life sciences industry. Veeva built CRM, content management, and regulatory software specifically for pharmaceutical companies. Their products handle the unique requirements of drug development: strict FDA compliance, clinical trial management, and medical review processes. $30B+ market cap.
Shopify — E-commerce platform powering millions of online stores. While Shopify looks horizontal at first glance, it's deeply vertical — every feature is built for retail: inventory management, payment processing, shipping labels, abandoned cart recovery, and in-store POS. Shopify merchants generated $235B+ in sales in 2024.
nCino — Banking operating system built on top of Salesforce. Instead of a generic CRM that banks have to customize, nCino ships pre-configured workflows for commercial lending, mortgage origination, and treasury management. This "built on Salesforce" model is a clever strategy: leverage Salesforce's distribution and trust while providing industry-specific value.
B2C SaaS Examples (Business-to-Consumer)
B2C SaaS sells directly to consumers. The dynamics are different from B2B: lower price points (typically $5-$20/month), larger user bases (millions instead of thousands), higher churn (consumers are less sticky than businesses), and viral growth through word-of-mouth.
Spotify — The canonical B2C SaaS success story. 600M+ users, 240M+ paying subscribers, $15B+ annual revenue. Spotify proved consumers will pay monthly for access rather than ownership — the same psychology that drove SaaS adoption in business.
Netflix — Started by mailing DVDs, Netflix became the world's largest streaming service by betting on the subscription model early. 280M+ subscribers. The lesson: be willing to cannibalize your own business model before someone else does.
Duolingo — Language learning app with 100M+ monthly active users. Duolingo's SaaS model uses freemium brilliantly: the free tier is genuinely useful (not crippled), but power users pay $12.99/month for unlimited hearts and no ads. Gamification — streaks, leagues, achievements — drives the kind of daily engagement most SaaS products can only dream of.
Headspace — Meditation and mindfulness app. Headspace proved there's a subscription market for digital wellness. $12.99/month for guided meditations, sleep content, and focus music. The product is content, which means low marginal cost and high gross margins — the SaaS dream.
Strava — Social fitness tracking. Strava's free tier captures runs, rides, and swims with GPS. The $11.99/month subscription unlocks advanced analytics, training plans, and route planning. Strava's real moat is the social graph: your entire training history and friend network lives on the platform.
AI & Machine Learning SaaS Examples
The AI boom has created a new generation of SaaS companies. Some are pure AI plays; others are existing SaaS products enhanced with AI.
OpenAI (ChatGPT) — The fastest-growing consumer application in history, reaching 100M users in two months. ChatGPT Plus ($20/month) and the API business (pay-per-token) represent two distinct SaaS models under one roof. OpenAI proved that consumers will pay for AI access and developers will build on AI infrastructure.
Anthropic — Claude, Anthropic's AI assistant, competes directly with ChatGPT. Claude's differentiation is safety and reliability — constitutional AI training produces more careful, nuanced responses. The AI & Machine Learning category is the fastest-growing segment in SaaS, with foundation model companies raising billions.
Jasper — AI content creation platform. Jasper was one of the first companies to build a SaaS product on top of GPT models, packaging AI writing into marketing workflows. The lesson: you don't need to build the AI — you can build the product experience around it.
GitHub Copilot — AI pair programmer integrated into the code editor. $10-$19/month per developer. Microsoft reported that Copilot generated over $100M in annual recurring revenue within its first year. Copilot proved that AI features can be monetized as independent SaaS subscriptions, not just bundled as free add-ons.
Midjourney — AI image generation with a SaaS subscription model ($10-$60/month). Unlike OpenAI, Midjourney skipped the free tier entirely — you pay from day one. It worked: Midjourney reached $200M+ revenue with zero venture capital and a team of under 50 people.
Micro SaaS Examples
Micro SaaS businesses are small, focused products run by tiny teams (often solo founders). They typically target a niche, generate $1K-$50K MRR, and are bootstrapped rather than venture-funded.
Carrd — Simple, single-page website builder. $19/year for pro features. Carrd does exactly one thing (build a one-page site) and does it perfectly. Founder AJ started it as a side project; it now generates millions in annual revenue with a team of one.
TinyPNG — Image compression tool used by millions of developers and designers. The business model is dead simple: free web compression, paid API ($0.009/image) for automated workflows. Zero marketing — the product is so useful it spreads entirely through word of mouth.
Plausible Analytics — Privacy-friendly Google Analytics alternative. $9/month. Plausible carved out a niche by being the ethical alternative in a market dominated by Google's free-but-invasive product. In a world of GDPR and cookie consent fatigue, Plausible's simplicity is the feature.
Tailwind CSS — Utility-first CSS framework that monetizes through a one-time UI kit purchase ($299) rather than subscriptions. While technically not SaaS, Tailwind shows that developer tools don't need the traditional SaaS model to succeed. Tailwind UI reportedly generates millions in annual revenue.
Nomad List — Community and data platform for digital nomads. Started as a spreadsheet of cities ranked by cost of living and internet speed. Now a paid membership community ($99-$299/year) with job boards, city guides, and social features. The ultimate niche SaaS: serve a tiny, passionate audience better than anyone else.
Enterprise SaaS Examples
Enterprise SaaS targets large organizations with complex needs. The products are more expensive (often $100K+/year), involve longer sales cycles (6-18 months), and require dedicated sales teams — but the contracts are massive and sticky.
ServiceNow — IT service management platform. ServiceNow digitizes enterprise workflows: when an employee needs a new laptop, the request flows through automated approval chains, procurement, and provisioning. $8B+ annual revenue. ServiceNow proves that "boring" enterprise workflow software can be an incredible business.
Workday — HR and finance cloud software. Workday replaced on-premise Oracle and SAP installations for hundreds of Fortune 500 companies. Once a company migrates payroll, benefits, and financial planning to Workday, switching is nearly impossible — the ultimate SaaS moat.
Datadog — Cloud monitoring and observability. Datadog ingests trillions of data points from companies' infrastructure and turns them into dashboards, alerts, and insights. The pricing scales with usage, which means Datadog grows as its customers grow. $2B+ annual revenue. Explore more Cloud & Infrastructure companies like Datadog.
Snowflake — Cloud data warehouse. Snowflake separated storage from compute, letting companies scale each independently and pay only for what they use. This usage-based pricing model (rather than per-seat) aligns perfectly with the Cloud & Infrastructure space where workloads vary dramatically.
CrowdStrike — Endpoint security platform. CrowdStrike's cloud-native architecture was a deliberate advantage over legacy antivirus products that required on-premise servers. When a new threat is detected anywhere in CrowdStrike's network, every customer is protected instantly — something traditional security software couldn't do.

SaaS Metrics: What Makes These Examples Work
The best SaaS companies share common traits. Understanding these metrics helps you evaluate any SaaS business — including the hundreds profiled on StartupWiki.
The Rule of 40
A SaaS company's revenue growth rate plus profit margin should exceed 40%. A company growing 60% year-over-year can lose money (60% + -20% = 40). A company growing 10% needs 30%+ profit margins. This single number captures the fundamental tradeoff in SaaS: growth vs. profitability.
Net Dollar Retention (NDR)
What percentage of revenue do you retain from existing customers after accounting for expansions, downgrades, and churn? The best SaaS companies have NDR above 120% — meaning existing customers spend 20% more each year even before adding new customers. Snowflake's NDR has been as high as 170%.
Customer Acquisition Cost (CAC) Payback
How many months of a customer's subscription revenue does it take to recover the cost of acquiring them? Best-in-class SaaS companies recover CAC in under 12 months. Enterprise SaaS with high upfront sales costs might take 18-24 months, but the lifetime value of those customers justifies it.
Gross Margin
SaaS companies typically have 70-80% gross margins because the marginal cost of serving one more customer is near zero. Infrastructure costs (AWS, cloud hosting) are the main variable expense. B2C SaaS with heavy content costs (like Netflix or Spotify) has lower margins due to content licensing.
Emerging SaaS Trends (2026)
AI-native SaaS. Companies built from the ground up on large language models rather than bolting AI onto an existing product. Examples include AI-powered Developer Tools like Cursor, AI legal assistants, and AI customer support agents. These companies look structurally different from traditional SaaS — they often charge per outcome rather than per seat.
Vertical SaaS 2.0. A new wave of industry-specific software that doesn't just digitize existing workflows but fundamentally reimagines them. Think: software that doesn't just track construction projects but uses computer vision to spot safety violations from site cameras. The Biotech & Life Sciences and Robotics & Automation categories are rich with examples.
Usage-based pricing. Per-seat pricing is giving way to consumption-based models where customers pay for what they actually use. APIs, cloud infrastructure, and AI services led this shift. The benefit: customers start small and grow their spend naturally. The risk: revenue is harder to predict.
Product-led growth (PLG). The best SaaS companies let the product sell itself. Free tiers, self-serve signup, in-product virality, and upgrade prompts replace expensive sales teams. The canonical playbook: sign up for free, invite your team, hit a usage limit, add your credit card. PLG works especially well for Developer Tools and Creative & Design Tools where the end user has purchasing authority. Explore our HR & Productivity category to see PLG in action across workplace tools.
Consolidation platforms. Instead of buying ten separate SaaS tools, companies want platforms that do everything. Rippling (HR + IT + Finance) and Notion (docs + wikis + projects + databases) represent this trend. The super-app model that worked for consumer tech is coming to B2B.
How to Learn From These SaaS Examples
Studying successful SaaS companies isn't about copying their features — it's about understanding their strategic choices.
Look at their pricing page. You can learn more about a SaaS company from their pricing page than from any press release. Who are the tiers for? What features are gated behind paywalls? How do they frame value? Stripe charges per transaction, Figma charges per editor, Slack charges per active user — each pricing model reveals who they think their customer is.
Follow their product evolution. The best SaaS companies expand deliberately. Stripe started with payments, then added billing, then tax, then banking. Each new product serves existing customers rather than chasing new markets. This land-and-expand strategy is how SaaS companies grow NDR above 120%.
Study their content and SEO. SaaS companies like HubSpot, Ahrefs, and Canva built massive audiences through content marketing before they became household names. Their blog posts from five years ago still generate traffic and leads today — the compounding advantage of content is real.
Earn backlinks from day one. Content compounds, but it needs links to rank. For a brand-new SaaS product, the StartupWiki launch board is one of the best places to pick up a do-follow backlink — the listing links to your site and keeps pointing at it long after launch week ends. It's a few minutes of work for a backlink that keeps paying off, so submit your launch early.
Read their S-1 filings. If a SaaS company has gone public, their S-1 is a goldmine. You'll see exact revenue numbers, customer counts, retention rates, and unit economics — the metrics that SaaS operators obsess over but rarely share publicly.
