B2B SaaS (Business-to-Business Software-as-a-Service) dominated startup investing in the 2010s-2020s, with companies selling cloud software subscriptions to other businesses rather than consumers.
Market Dominance
By 2023, B2B SaaS represented 70%+ of venture capital investment in software. Why? Predictable recurring revenue, lower churn than consumer, higher willingness to pay, longer customer lifetimes. Public B2B SaaS companies (Salesforce, ServiceNow, Workday, Snowflake) reached $100B+ valuations.
Iconic Companies

Business Model Advantages
Higher ARPU: $50-$500/seat/month vs consumer $5-$15/month. Enterprise contracts: $100K-$10M+ annually.
Lower Churn: Businesses switched software reluctantly—migration painful, team training costly. Annual churn 5-15% vs consumer 40-60%.
Expansion Revenue: Land-and-expand model—sell 10 seats, expand to 1,000. Negative net revenue churn (expansions > cancellations).
Profitability Path: B2B SaaS could bootstrap or achieve profitability. Consumer required massive scale.
Sales Models
Self-Serve: Product-led growth (Slack, Notion, Figma)—sign up free, upgrade when needed. Works for <$500/month products.
Sales-Assisted: Hybrid—start self-serve, sales calls $10K+ deals. Calendly, Loom, Miro models.
Enterprise Sales: Dedicated sales teams, 6-18 month cycles, $100K+ contracts. Salesforce, ServiceNow, Workday.

2021 Boom → 2022 Bust
ZIRP era saw B2B SaaS valuations hit 50-100x revenue (Snowflake 100x+ at IPO). 2022 correction crashed multiples to 5-15x. Companies that raised at $1B+ valuations faced 70%+ markdowns. Survival required “path to profitability”—opposite of 2021’s growth-at-all-costs.
