How I got here
Started in design and tech
I led teams building web and app solutions at a Munich agency. UniCredit, MunichRe, Mammut. Won a RedDot Design Award. This is where I built my customer instinct.
Joined a Silicon Valley venture builder
I joined Mach49, a Silicon Valley venture builder. I built ventures inside Goodyear, TDK, Schüco, Airbus, Shell, and Anglo American. Ran 200+ customer discovery interviews across 6 continents.
Co-founded an AI company. Got a YC interview. It failed.
Tarka.ai. We reached revenue. Got customers — Ecotone, troupe.ai, Atlas. But fighting LinkedIn’s ecosystem was a battle we couldn’t win. This is where my founder empathy was forged.
Building again
Ergoly.ai — AI workers for non-technical founders. I’m still in the arena. Not advising from the sidelines.
Don't take my word for it
AJ translates ideas into working prototypes faster than anyone I’ve worked with. His deep dives into new business models were exactly what our incubation project needed.
Nicolas Montag
Corporate Venture Builder, Schüco
His constant enthusiasm, interpersonal skills, and concern for customer satisfaction allowed an excellent collaboration built on trust and transparency. Thanks to his technical developer skills, a functional prototype could be rolled out!

The short version
My name is Aljoscha, but everyone calls me AJ. I work with US and European clients across both time zones, and speak English and German natively.
I work best when I'm embedded in your team — not delivering reports from the outside. I'll join your standups, pair with your engineers, talk to your customers, and push back when the roadmap doesn't add up.
Outside of work, you'll find me sailing on my catamaran. It's where I do my best thinking and where I learned that the simplest solution is usually the right one.
Common questions
What does a Fractional CPO do?
A Fractional CPO embeds with your team 2–3 days per week to own product strategy, run customer discovery, align stakeholders, and drive execution — without the cost of a full-time C-suite hire.
Who is this for?
AI startups (seed to Series B) that need product leadership, and enterprise innovation teams building new ventures or digital products.
How is this different from a consultant?
Consultants deliver a deck and leave. I embed with your team — joining standups, pairing with engineers, talking to customers. I’m accountable for outcomes, not deliverables.
How much does it cost?
A Product Strategy Sprint starts at $5K (2–4 weeks). Fractional CPO retainers run $10–20K per month for ongoing embedded product leadership.
