In 2024, the global liquid cooling market was valued around $4.18 billion and is projected to reach $13.2 billion by 2029.

You’re probably not combing through cloud bills. That’s not your job as CEO. But if no one on your executive team can tell you what it costs to serve a customer, ship a feature, or launch a new product line, that’s a problem. Not a someday problem. A right-now, quietly-draining-your-margins kind of problem. FinOps tends to get lumped in with cost-cutting — some finance thing, some DevOps thing. But that framing misses the point. Done right, FinOps is a growth enabler.

Picture this. Gartner forecasts worldwide end-user spending for public cloud usage to total more than $720 billion in 2025 — up from $595 billion in 2024. Out of that spend, SaaS will make up a chunky $299 billion. For comparison, Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) will make up nearly $212 billion and $209 billion, respectively. Elsewhere, BetterCloud’s State of SaaS 2025 report found that the average organization uses 106 different SaaS tools.

It’s 2 AM. Your API is timing out. Logs show a slow query. Metrics flag a spike in DB connections. Traces reveal a 5-second delay on a database call. But then the questions start:- Which database?- Does the query match the delay?- Why doesn’t this align with the connection pool metrics? Each tool uses different labels, db.name, database, sometimes nothing at all. Without a shared schema, connecting the dots is slow and frustrating.
