The founder's path is hard
We've walked it ourselves
Built by experienced technical founders, Petrus Labs helps early-stage startups build with confidence by providing hands-on support across fundraising, operations, and everything in between.
We help technical founders navigate their own journey with courage and clarity.
O1 Product & Sales
Building is hard. Positioning and selling are harder, and rarely a technical founder's first language. We help you navigate go-to-market and open the right doors so you reach escape velocity faster.
O2 Fundraising
As a founder, you seldom raise money, while the investors do this every day. We help you craft your story, make warm introductions, and help you navigate the gauntlet so you can get back to building.
O3 Operations
Founders get weighed down by operational toil. It has to be done, but your mind is better spent on the product and the strategy. We provide support that you need to focus on what matters.
Decades running successful companies.
Now we're supporting the next wave.
Petrus Labs was started by operators, not career investors. Our founding team has built, scaled, and exited companies in data infrastructure, and held product and engineering roles at Google, Airbnb, and Netflix. Learn from our experience, we help where it counts.
