Precision Capital for Exceptional Founders

Founded by investors who have been on both sides of the table

KnownWeil Capital was established in Paris in 2019 by a team of former operators and institutional investors who grew frustrated watching exceptional founders receive undifferentiated capital from managers who could not — or would not — offer meaningful operational support.

Our founding partners bring together decades of experience scaling technology companies from seed to significant scale across Europe, the United States, and emerging markets. We have held roles as engineers, product managers, general managers, and CFOs before becoming investors. That operational grounding shapes every aspect of how we work.

The name KnownWeil reflects our core belief: the best investment decisions emerge from deep knowledge — of the market, the technology, the team, and the broader competitive landscape. We invest in founders we know well, in sectors we understand deeply, and with capital structured to give companies the best possible chance of success.

Today, KnownWeil Capital manages a focused seed portfolio of 28 technology companies across Europe and North America. We write seed checks of $500K to $5M, typically leading rounds or co-leading alongside one trusted co-investor. We do not spray and pray. We choose sides and commit fully.

What we look for

Exceptional Founders

We prioritize founder quality above all else at the seed stage. We look for individuals who combine domain insight with the tenacity and judgment required to navigate the first critical years of company building. Previous founder experience is valued but not required.

Large, Defensible Markets

We require that the market opportunity be large enough to justify building a durable, independent business. We are equally interested in companies creating new categories as in those displacing legacy incumbents with structurally superior solutions.

Durable Competitive Moats

We seek companies building network effects, proprietary data assets, switching costs, or economies of scale that will compound over time. We are sceptical of businesses that are merely better, faster, or cheaper without a structural advantage protecting margin and growth.

Capital Efficiency

We value founders who understand unit economics and build lean organizations that can reach meaningful milestones before requiring additional dilutive financing. Disciplined capital allocation is a learned skill that separates great operators from merely ambitious ones.

Partners, not spectators

KnownWeil Capital operates as a genuine partner to our portfolio companies. We do not attend a single board meeting per quarter and consider our job done. We engage continuously, proactively, and candidly — even when the news is difficult.

Our team brings specific functional expertise across hiring, sales strategy, product development, financial modelling, and international expansion. We match each portfolio company with the team member whose background is most relevant to their current challenges, and we adjust that match as the company's needs evolve.

Our network is one of our most valued assets. We have cultivated relationships with corporate development teams at major technology companies, senior executives at potential customer accounts, and co-investors who can lead follow-on funding rounds for our portfolio. We make these introductions deliberately and at the right moment in a company's growth.

We believe in transparency with our founders. We share our internal financial models, our views on the fundraising landscape, and our honest assessment of company performance. We expect the same candour in return. The best partnerships are built on truth, even when the truth is uncomfortable.

The principles that guide us

Integrity

We keep our commitments, communicate clearly, and act consistently whether or not we are being observed. Our reputation is built one interaction at a time.

Conviction

We make concentrated bets because we do our homework. We do not hedge with portfolio size. When we invest, we invest completely.

Candour

Honest feedback, delivered thoughtfully, is the most valuable thing we can offer. We share our views directly and expect the same from those we work with.

Patience

Great companies take time to build. We are long-term investors by design and temperament. We do not pressure companies toward premature exits or artificial milestones.

Curiosity

We read deeply, seek out contrarian perspectives, and remain genuinely open to being wrong. The best investment insights come from questions, not assumptions.

Partnership

We treat our founders as partners, not clients. Their success is our success. We celebrate wins, work through setbacks, and remain committed through the full journey.
