About Us

We’re an early-stage startup on a mission to supercharge Excel with AI for finance professionals — think private equity, venture capital, and corporate finance teams. Backed with €1M in funding, our small but ambitious team of 4 is building the next-generation productivity tool for the financial world.

The company is led by a founder who previously co-founded Templafy and scaled it to a €350M valuation — now starting a new chapter, building lean and fast from Berlin.

We’re looking for a Founding Fullstack Engineer who thrives in early-stage chaos, loves solving hard technical problems, and wants to help define both the product and the culture from day one.

Your Mission

You’ll be our technical cornerstone — building the bridge between web and desktop. You’ll work across both the React/TypeScript frontend and the C#/.NET Excel connector that powers our core product. You’ll take full ownership from MVP to the first production release, setting the technical direction and helping shape the future of our platform.

What You’ll Do

Build the core product: Develop and scale both the web app (TypeScript, React, Node.js) and the Excel connector (C#/.NET).
Go from MVP to v1.0: Translate vision into a reliable, production-ready product used by real customers.
Shape the tech foundation: Make key architectural decisions, define coding standards, and ensure performance and security.
Collaborate closely with the founder and team: Work side-by-side in Berlin to iterate fast and ship meaningful features.
Own and grow: Take full responsibility for your domain and help build the company’s engineering DNA.
