The discipline behind impact: notes from Impact Future Weekend

3P Ventures joined Impact Future Weekend, hosted by We Are The Impact at Tokyo Innovation Base. We came to share an investor's perspective — and to talk about the work we're building through 3P Ventures and PitchVault.ai — but left with a notebook full of the founders and ideas in the room. A few threads stayed with us.

A powerful mission is not enough

The sharpest line from the “How Impact Capital Really Works” panel — with Tove Kinooka, Alexis Rocamora, Ryuta Shibusawa, and Lee Jean — was that a compelling mission is table stakes, not a moat. What separates fundable impact ventures is a clear articulation of the problem, a product that plainly addresses it, and a way to measure the impact over time. Founders often rush to build a solution before they've understood the problem through real conversations with users. That's the same discipline we underwrite at 3P — people, process, and product — whether or not “impact” is in the name.

Sustainability has moved onto the balance sheet

Another thread: sustainability is no longer a “nice to have” bolted onto a business. It's increasingly priced into mainstream financial decisions through risk, returns, and long-term performance. And even in the age of AI, many of the most meaningful problems remain deeply human — not everything needs to be solved with technology. For an operator-led fund working the US–Japan corridor, that's a useful correction: the durable companies pair real technical or operating capability with a problem people actually feel.

The founders we won't forget

The Founders' Journeys session was the one we didn't want to end. Tanatsiwa Dube (Tahris!) is building accessible, affordable hypoallergenic self-care for people with skin and respiratory sensitivities, starting in underserved communities in Zimbabwe. Christine Bagarino (Social AI) shared the moment her team was cut after a pivot — and why she kept fighting for the education problem she cared about. Sasha Lee Seals (Nagareyama Lead) spoke as both educator and parent about the gap between what schools reward and what young people actually need to become problem-solvers. Raw, honest, and a reminder that the earliest signal is so often personal. Thanks to co-host Ichigo Bloom for the Gender Equity Collage workshop, and to We Are The Impact for the room.

We left with two open invitations. 3P is working to connect strong Japanese startups with the Johns Hopkins University alumni and incubation network in the US — and, in the other direction, to introduce Japanese investors to ventures emerging from that ecosystem. If that resonates, we'd love to talk. Moments like this are why we do the work: the most durable companies, impact-driven or not, are built by people solving a problem they can't stop thinking about.
