Why a project holding builds itself today
Company building is not new. What is new is that it can be more personal, collaborative, and operational than the classic factory ever was. Our model in three moves.
The principle of systematically building companies yourself rather than only investing in them is not our invention. In Germany, Rocket Internet and the Samwer brothers showed the pace at which digital companies can be launched from a central structure. What we keep is the speed and the discipline. What we change is the tone: more personal, more collaborative, closer to the people who actually build.
Weidner Ventures is a studio and a holding in one, based in Berlin-Mitte on Unter den Linden. Not a pure capital provider and not a pure factory, but a structure that works in three moves: Build, Accelerate, Back.
Build, Accelerate, Back
Build means starting our own digital companies from the ground up. Not buying a deck and hoping, but founding, staffing, and shipping ourselves. This move produced the environment around The Agentics and Slabhit.
Accelerate means giving what already exists what growth demands: capital, brand, performance, operators, network. Cryptoticker, an established crypto and finance media outlet, is an example of a participation that does not start from zero but gets accelerated. The operating force for this comes from Weidner & Friends, the group's agency for performance marketing, digital platforms, AI enablement, and consulting.
Back means selective co-investments, smaller tickets, collaborative. Not every good idea has to come from our own house. Where others lead and we can sensibly add, we participate, without any claim to control everything. On top come mandates like EverHub, which we accompany in an advisory role.
Passive capital waits for results. A studio produces them.
Why owning and operating beats passive capital
The classic fund has a structural problem: it may advise but not intervene. It sits on the board, writes a memo, waits for the next quarter. A studio that builds and owns has no such distance. It stands inside operations, it is accountable for decisions, and it therefore learns faster and more honestly. Ownership here is not an end in itself; it is the precondition for keeping responsibility and knowledge in the same place.
Within the group, that separation of roles is built on purpose. Weidner Ventures is the patient holding that owns and sets direction. Weidner & Friends is the operating face that works in the market. This keeps the capital patient and the operating layer agile: two jobs that should never be forced onto the same line of the balance sheet.
Why this can be more personal now
The old company-builder factory was a power plant: efficient, industrial, interchangeable in its roles. Today the most expensive resource is not capital but good operators and real trust. Neither scales through process; both scale through relationships. That is exactly what our network is built on, in part through Gründerfreunde: people who know, recommend, and build with one another, rather than meeting only across term sheets.
That is why a project holding builds itself today, not out of ideology, but because it is the more honest way to learn in fast markets. Whoever owns and operates has to be right where it counts: in operations, not in the memo. That is the model. Build, Accelerate, Back, in that order, with that stance.
