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.
Patient capital, operating power.
Weidner Ventures is the holding: it holds the stakes and invests. Weidner & Friends is the operating arm that delivers the work. That is how we contribute real work in our Knowledge & 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.
We give more than capital.
Inspired by the tempo of the great company builders, but more personal and collaborative: we bring not just money, but operating experience, 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 scale together
Capital, brand, performance and operators from one source, the moment a venture is ready to grow.
We back founders, selectively
Smaller tickets, collaborative and on eye level. For founders who build something genuinely substantial.
Four ways, not just cash.
You may know media-for-equity from ProSieben. Ours is Knowledge & Work for Equity: knowledge, work and reach in exchange for equity, valued at market rate and cleanly documented. Plus classic cash, convertibles and, where Web3 creates real value, tokens.
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 and work.
Convertible loan
Fast capital today that converts into equity at the next round. The clean bridge for cash and valued work.
Token participation
We live in the decentralized world (among others through Cryptoticker) and, where Web3 creates real value, we also participate via tokens.
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.
The fields we look at.
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.
Blockchain, Web3 & infrastructure
Decentralized infrastructure, Web3 and token economies. A field Cryptoticker has made us deeply at home in.
Digital platforms & media
Audiences, knowledge and platforms that compound.
Sport & fitness
Franchise and venue concepts with a clear operating model, from padel to Hyrox to golf, together with experienced partners.
Nutrition & health
Brands and platforms for healthier living. A field where we bring our own experience.
Through a grown network we also understand markets beyond these nine fields.

Send your pitch →What we're building right now.
No shop window of old logos, just what we are actually working on today. Every position clearly labelled: own venture, participation or mandate.
I have founded several companies and still run them today. Every investment is paid out of our own pocket, with money we earned ourselves first. That keeps every decision honest. And because we know how much work lies between a good idea and a working business, we bring exactly that work to the table, as capital.
Building something the world hasn't seen, or solving a real problem?
Send us your pitch deck, or just a few sentences. Once a week our investment committee meets, Dennis Weidner and befriended business angels from a network grown over many active years. We help with capital and with work, and you always hear back within one to two weeks. Even if it's a no.
Send
Your deck or a short pitch by email. Short and honest beats long and polished.
