Pre-seed / Seed
Where we concentrate.
The earliest defensible moment. The thesis is real, the company is not yet built. This is where our help counts most, because the decisions we make together on day one shape everything after.
What we do · Venture Capital
Early conviction, where the work compounds.
We back founders when our help matters most, at pre-seed and seed. We stay close through the inflection points that follow. The check starts the relationship. It doesn't end it.
Our thesis
The best time to add real help is before the company is built.
Capital is a commodity at the early stage. Judgment isn't. We invest where our experience changes the trajectory, not where we'd just be along for the ride.
Red Ruby is pre-portfolio by design. We're building the process before the pressure. The approach is simple: find the rare gem inside an idea or a market, back it with conviction, and help the founder build it out rather than settle for a smaller version.
We evaluate through frameworks the team has used for years: Clayton Christensen on disruption and jobs-to-be-done, MIT on innovation and platforms, Brad Feld on how ecosystems form. Not for their own sake, but to make decisions we can trace and defend.
Where we invest
Primarily early. Selectively later. Occasionally in special situations.
We concentrate at the stage where our help matters most, and we participate later only where the inflection is real.
Series A+
Selective, at the inflection.
We come in later only when the inflection is real. A company that has found its wedge and needs conviction to press it. We follow the work, not the round.
Special situations
The pivot others miss.
Later-stage pivots where a strong team is on the wrong version of the right idea. We know how to find the bigger company hiding inside one that has drifted, and how to help build it.
What the founder gets
Capital, and the help that makes it count.
Operators in the room.
We've built and run companies. That experience comes with the check: strategy, hiring, go-to-market, and the calls with no clean answer. Not board theater. Real work.
Ecosystem access.
Our edge is who we know, and how early we know them. We open doors to operators, customers, and co-investors through relationships built over years. It's the Brad Feld playbook for how ecosystems compound.
Conviction at the inflection.
When the data turns, most capital hesitates. We don't. We commit reserves up front, so when your moment comes, the follow-on decision is already made.
