We invest our own capital and our own work.
Weidner Ventures is an operator-led investment holding, not a fund. We deploy capital we earned by building our own companies, and we back founders the way we know best: with cash, and with strategic work in exchange for equity.
One holding that holds. One arm that delivers.
Weidner Ventures is the holding – it holds stakes and invests. Weidner & Friends is the operating arm that delivers the work. That is how we contribute real work in our work-for-equity model, not just money.
Holds the stakes and invests its own balance-sheet capital. Does not operate itself.
Delivers the work: marketing, build, platforms, AI enablement – also as a contribution against equity.
Own ventures and participations that the group's capital and work accelerate.
Not a passive check. A house that builds.
Inspired by the tempo of the great company builders, but more personal and collaborative: we bring not just money, but building, brand and people.
We start our own companies
From concept to market, as founders, not spectators. Our own ventures are the core of the portfolio.
We add the next gear
Capital, brand, performance, operators and network, from one hand, when a venture is ready to scale.
We back founders, selectively
Smaller tickets, collaborative and on eye level, for founders who build something genuinely substantial.
Cash is only one of three doors.
You may know media-for-equity from ProSieben. Ours is Knowledge for Equity – we contribute knowledge, work and reach in exchange for equity, valued at market rate and cleanly documented.
A classic stake
A direct participation in cash, usually smaller tickets, often alongside other business angels.
Knowledge & work for equity
The group contributes valued packages of knowledge, build and marketing – and takes equity in return. The media-for-equity logic, applied to knowledge.
Convertible loan
Fast capital today that converts into equity at the next round – the clean bridge for cash and for valued work.
Is knowledge-for-equity even legal?
Does it disadvantage the cash investors?
What makes such a deal clean?
Note: general information, not legal or tax advice. The concrete structure always belongs with a lawyer and tax advisor.
Where we look.
We move where technology meets real demand – on offense, not only on defense.
AI agents & agentic systems
Software agents that take on real work, under human governance.
Live commerce & shopping entertainment
Selling as entertainment: discovery, auctions, creator-led commerce.
DeepTech
Hard technology with a defensible edge and long-term value.
Defense & security
Dual-use and security technology for a changed world.
Fintech & crypto
Digital finance, payments and crypto media with reach.
Digital platforms & media
Audiences, knowledge and platforms that compound.
What we build and hold.
No shop window of old logos. Only what we actively build, hold or accelerate today – clearly marked as an own venture or a participation.
Everyone is arming up defensively, staring at the same themes. But people still want to discover, buy and be entertained. AI agents are our tool for that – not the goal.

Why we built The Agentics instead of just advising
On backing an AI-agent venture and building it, rather than watching from the sidelines.
