Founding engineers wanted.
Build what matters with us.
Based in Berlin · On‑site
We have three clear bets and the playbooks to build them. We’re looking for YC‑level builders with product taste to make them real—fast.
A letter to the founding engineers who want to build what matters
If you’re reading this, you’re probably not a normal engineer. You care about more than code. You care about what gets built, why it matters, and how it lives in people’s lives.
You can go from zero to something real in days, not months. You obsess over product feel, not just functionality. You think like an inventor. And when you’re surrounded by people who match your intensity, you can do the best work of your life.
We’re looking for you.
We have three very clear bets—ventures where we already know the playbook, the product vision, and the first versions to build. These aren’t vague explorations. We (Louis Morgner & Bjoern Keune) will lead each venture and work with you directly to execute. Your job: be the technical mind and product architect that turns the vision into reality.
The environment is Acta. We’ve built and scaled companies before. We designed Acta so personal growth isn’t an afterthought—it’s the core of how we work (see our letter, manifesto, and DAO track). If you join, you’re not just getting one job. You’re getting the space to do the best work of your life with people who care about the craft.
- Co-create from day zero with proven top 1% founders.
- A fast lane for your own growth through our culture and DAO track.
- Real ownership with high upside—and financial stability.
We’re not offering you a job. We’re offering you a seat at the table where things get made—and made well.
— Louis & Bjoern
The three bets
Clear wedges, aggressive v1s, real moats.
Helps ambitious people design and live the life they want.
- Who: founders, operators, top 1% performers.
- Why now: LLM reflection + on‑device memory → real personalization.
- V1: daily prompts, voice journaling, weekly review → action plan.
- Edge: private by default, long‑term memory, taste in coaching.
Turns teams into systems that execute without meetings.
- Who: 5–50 person teams.
- Why now: Slack‑native work + LLM summarization → fewer status meetings.
- V1: metrics hub + async check‑ins + risk flags, shipped in Slack.
- Edge: zero‑friction adoption, strong defaults, tight integrations.
The “head of marketing/CEO” for agent‑native workforces.
- Who: engineers building agent pipelines.
- Why now: function calling + tool use matured; needs real ops primitives.
- V1: project.yaml → roles, tools, budgets, guardrails; local‑first runner.
- Edge: determinism, audit trails, cost controls, first‑class testing.
