The company

Our partner offers an open-source platform that automates network, cloud, and security infrastructures, reducing the complexity of traditional technical tools. Backed by €7 million in funding from top-tier VCs and supported by an experienced 20-person team, they've already found their product-market fit, reached €1 million in ARR, and are preparing for their next fundraising round.

They’re now looking for a late co-founder to join the adventure, someone who could come from an Engineering, Operations, or GTM background. They are open to diverse profiles that complement the founding team’s strengths in tech, product, and vision.

“You’ve built the product we’ve been trying to develop internally for four years.” —
