Rising Tide Partners Fund I backs nine companies — charted here in full. Behind them stands a track record of 40+ prior investments through Interlock Capital and personal angel deals. The judgment and access predate the fund.
Commercial aviation still flies the same tube-and-wing shape it has for seventy years. Natilus builds a family of blended-wing-body aircraft — KONA for freight and HORIZON EVO for passengers — for roughly 30% less fuel burn, more volume, and less noise.
The ocean is the largest sensing gap on Earth. Seasats builds solar-electric autonomous surface vessels — the Lightfish flagship runs up to six months and 8,000nm, Quickfish sprints past 35 knots, and Heavyfish follows in 2026. Missions completed for defense, science, and commercial customers worldwide.
MEMS fabrication has been stalled for decades. Omnitron builds the first 3D-designed micromachine — bringing 3D polysilicon to hybrid sensor and actuator design for orders-of-magnitude gains in performance, precision, and reliability at lower cost. It unlocks more responsive AI data centers, greater autonomy, climate sensing, and next-generation XR.
The earliest signal of disease is the hardest to read. Xzōm harnesses extracellular vesicles (exosomes) via a proprietary Alternating Current Electrokinetics (ACE) platform — isolating and analyzing them from under 100µL of blood in less than 30 minutes. Lead target: early pancreatic cancer detection.
Bluefin tuna is the pinnacle of seafood — and increasingly at risk. BlueNalu develops cell-cultivated seafood, beginning with bluefin tuna toro: exceptional seafood made without fishing. Founded in Hawaii, now rooted in San Diego.
In modern conflict, fixed factories are targets and supply chains can’t keep pace. Firestorm Labs builds xCell — a containerized factory that deploys to the point of need and prints what the mission demands. Its flagship output is modular drones, printed in under 24 hours; the same platform has printed vehicle parts on-site that would otherwise take months to source. One idea underneath: affordable mass, manufactured wherever the fight is.
Communities run on gatherings, and gatherings need infrastructure. Eventship is the platform for hosts who build community — events, registration, and the connective layer underneath.
The pool guy never changed — opaque, analog, easy to doubt. Cabana modernizes pool service end to end: an instant online quote in minutes, vetted certified techs for weekly cleaning and repair, and a timestamped photo plus chemical report after every visit.
Competitive games live in walled-off silos. Bear Club Games is a new studio modernizing competitive genres in one dynamic world — built for player loyalty that compounds over years, not weekends.
Nine companies backed through RTP Fund I — the flagship systems charted above.
Years of investing through Interlock Capital and personal angel deals — the relationships, judgment, and access that RTP Fund I is built on. The track record that proved the model before the fund existed.
