Ways we work together

I make AI real for the people who build and run things. Here's how we work together.

No sales funnels. I build, I back, I advise — and, selectively, I step in and operate. Only where the fit is mutual and the work actually matters.

Building an AI-native thing? Read Out of Band first — my take on agents, building, and Berlin.

I've built and led tech companies in Berlin for a decade — as CTO, as CEO, and as an investor. What I care about is the moment a technology stops being a demo and starts being something an organization can win with. That's the space I live in. If that's where you're building too, one of these four ways is probably how we should work together.

André Beyer — CTO, CEO,and investor in Berlin

AI generated

I build with you.

Partner on something worth owning

Not as an advisor from the sidelines — as someone with skin in the game.

What I bring

Deep technical architecture — AI/LLM systems, agentic architectures
A builder's instinct for turning an idea into something shipped
Entrepreneurship experience
My network, my capital, and my full attention

Who this is for

Technical co-founders and operators who want to build something real and AI-native — not another wrapper, not another pitch.

Let's talk about building something real

I back you.

Early capital from someone who's been in the arena

I invest in people first, slides second.

What you get

Pre-seed and seed checks into AI ventures
An operator's perspective, not just a check
My network of founders, operators, and investors across Berlin and internationally
Honest, direct feedback — no polite maybe

Who I'm looking for

Founders with conviction, real technical depth, and a problem they've clearly owned. Vertical AI, agentic systems, automation infrastructure.

Send me what you're building

I advise you — selectively.

Paid advisory for real decisions

Project-based or a short retainer — aimed at a decision, not a steady stream of hours.

What this covers

AI strategy deep-dives — what to build, what to skip, what to own
Architecture and evaluation reviews for LLM and agentic systems
Operating advice — hiring, roadmaps, and the questions in between
Honest, direct feedback — no polite maybe

Who it's for

Founders and companies with real AI decisions to make. A small number of engagements, taken on selectively — if you need an agency, I'll tell you.

Ask about advisory

I step in — selectively.

Operator for the right story

Not a service. An operator with skin in the game, for the right reasons.

What this looks like

Stepping in as CEO or CTO where a founding team needs a counterweight
Equity over fees — I'm invested in the outcome, not the invoice
Only where the vision, the team, and the chemistry genuinely click
I stay as long as the story needs me — sometimes as a permanent part of it

Who it's for

Companies I'd genuinely want to be part of. If I wouldn't own the outcome, I don't take the seat.

Reach out if the fit feels mutual

What I look for

Three things earn my attention:

Warm introductions — from people I trust

Signal in the work — shipped product, real traction, or genuine technical depth

Shared obsession — you care deeply about something I also care about

If this reads like a pitch for agency services, it's probably not the right fit. Advisory is the exception, not the model.

If you're genuinely building something worth owning, it always is.

How to reach me

A note, not a funnel.

Tell me what you're building or where you're stuck. If the energy's there, we'll talk.

Out of Band — the signal channel, outside the noise.

Biweekly. AI agents, building, and the Berlin ecosystem. No fluff, no spam.

If you're building something worth owning — or backing someone who is — let's find out if the fit is mutual.
