GrowthLab raises $48M series C to build the operating system for growth teams

Today, I'm thrilled to share that GrowthLab has raised a $48M Series C led by Lightfall Ventures, with participation from Accel, Basis Set, and all of our existing investors. This brings our total funding to $71M.

More important than the number is what it represents: a bet that the way growth teams work is fundamentally broken — and that we're the team to fix it.

Where we started

Three years ago, my co-founder Dev and I were running growth at a Series B startup. We had Stripe in one tab, Amplitude in another, a warehouse we paid a contractor to maintain, and a Notion doc where we manually copied numbers every Monday. We were spending more time assembling the picture than acting on it.

We built GrowthLab because we wanted the tool we wished we'd had: one place where acquisition, product, and revenue data live together, in real time, with AI that tells you what to do next.

Where we are today

Since launching, we've been humbled by the response:

• 4,200+ companies now run their growth on GrowthLab

• Customers connect an average of 9 data sources in their first week

• Our AI insight feed has surfaced an estimated $340M in recovered or expanded revenue across our customer base

• We crossed $12M in ARR — growing 3.1x year over year

Numbers like these come from one thing: teams finally trusting their data enough to move fast on it.

What we're building next

This funding lets us accelerate three bets we've been making quietly:

1. The Growth Agent. An autonomous layer that doesn't just surface insights — it drafts the experiment, estimates the impact, and queues it for your approval. Think of it as a tireless growth analyst that never sleeps.

2. Warehouse-native deployment. For larger teams, GrowthLab will run directly on top of your Snowflake, BigQuery, or Databricks instance — no data ever leaves your environment.

3. The Growth Graph. A model of how every metric in your business influences every other one, so you can finally answer "if I move this, what happens downstream?"

Thank you

To our customers: thank you for trusting an early, scrappy product with something as important as your growth. To our team of 38 — soon to be many more — thank you for caring about the craft.

We're hiring across engineering, design, and go-to-market. If building the operating system for growth teams sounds like your kind of problem, we'd love to hear from you.

The best growth tooling hasn't been built yet. We intend to build it.
