SaaS is the “fad” that hasn’t waned yet. It’s still the fastest-growing slice of IT, with Gartner’s 2025 outlook showing the industry will nab ~$300 billion this year, though it acknowledges that buyers are increasingly scrutinizing the benefits their subscriptions earn them and looking for more proof that spend is leading to results.
While the industry keeps growing, that increased scrutiny (and an impulse to consolidate an increasingly sprawling software landscape), the operating math for SaaS companies is changing.
Today, SaaS companies will have to tell a more concise story, deliver results, and build trust upfront. It takes more to find product/market fit, hone their message, decide on a more complicated marketing strategy, and then implement it at scale. What were once big jobs have become gargantuan ones — luckily, SaaS companies continue rising to the occasion.
We put our heads together and refined metrics on SaaS companies that have received lots of funding and are funded in the Silicon Valley ecosystem. This ranking sheds light on the hottest SaaS companies and allows for clear comparisons with similar funding and business models. It also applies the power laws to funding and company concentration in this space.
