Quick Answer
Software as a Service — cloud-delivered software accessed via subscription, generating recurring revenue. The dominant business model in modern enterprise software.
SaaS (Software as a Service) is a software delivery model where applications are hosted in the cloud and accessed by customers via subscription — rather than installed on-premises with a one-time license fee. SaaS became the dominant enterprise software model in the 2010s, displacing traditional on-premise software. Key characteristics: predictable recurring revenue (ARR/MRR), high gross margins (70-80%+), scalable infrastructure costs, network effect opportunities, and high switching costs once integrated. SaaS unit economics are evaluated on metrics like NRR, churn, CAC, LTV, and ARR growth rate. The SaaS model is highly attractive to VCs because of revenue predictability, scalability, and the potential for net dollar expansion (charging existing customers more over time). Salesforce pioneered enterprise SaaS; Slack, Zoom, and Datadog are more recent exemplars.
In Practice
When CloudAnalytics launches their business intelligence platform, they choose a SaaS model over traditional licensed software. Instead of charging $50K upfront for on-premise installations, they offer tiered monthly subscriptions: $99/month for startups, $499/month for mid-market, and $2,000+/month for enterprise with custom features. This generates $180K ARR from their first 50 customers within 12 months. The recurring revenue model allows VCs to value CloudAnalytics using SaaS metrics like 8-12x ARR multiple, leading to a $15M Series A on $1.5M ARR. The predictable revenue stream and 85% gross margins (typical for SaaS) make the business highly attractive to growth investors who can model future cash flows with confidence.

Why It Matters
SaaS fundamentally changed how VCs evaluate and value software companies by creating predictable, recurring revenue streams that compound over time. The subscription model provides clear metrics (ARR, churn, LTV/CAC) that allow investors to model growth trajectories and terminal values with greater confidence. For founders, SaaS enables faster scaling with lower upfront customer costs, but requires mastering unit economics and retention. Poor SaaS metrics like high churn or negative unit economics can kill valuations quickly, while strong metrics like net revenue retention above 110% command premium multiples from growth investors.
VC Beast Take
SaaS has become so dominant that many founders force inappropriate business models into subscription frameworks just to appeal to VCs familiar with SaaS metrics. Not every software business should be SaaS - sometimes usage-based pricing, marketplaces, or transaction models create more value. The most successful software companies we see pick the revenue model that best aligns with customer value creation, then educate investors on their specific unit economics. The blind pursuit of ARR has led to unsustainable businesses that prioritize growth over profitability.
