When a patient needs a transplant organ, a rare antivenom, or a time-critical lab sample, the delivery clock matters as much as the medicine. A new Houston startup wants to fly that cargo autonomously. Haast Autonomous, founded by three recent Rice University graduates, has raised $1.85 million in pre-seed funding to build a network of self-flying drones purpose-built for the most sensitive cargo in medicine.
What They're Building
Haast is developing a custom autonomous aircraft designed specifically for medical logistics — not a repurposed hobby drone. The aircraft uses vertical takeoff and landing (VTOL), so it needs no runway and can operate from hospital rooftops and small pads. Each drone carries a 5-plus-pound payload over a mission range of roughly 50 to 62 miles, enough to connect facilities across a metro region, with larger versions planned.
The part that makes it a genuine medical device rather than just a delivery drone is the payload bay. It's climate-controlled — actively regulating temperature, pressure, vibration, and tilt — because the cargo it's designed to carry doesn't tolerate rough handling. A donor organ, a vial of patient samples, or a radioligand therapy has to arrive in exactly the condition it left. Layered on top is software managing dispatch, routing, and chain of custody, so every handoff is tracked.
The company started by targeting organ transplants — one of the hardest, highest-stakes logistics problems in medicine — and expanded from there to patient samples, antivenom, poisoning-treatment kits, and radioligand therapies. "We are building the fastest, most secure logistics chain for the world's most sensitive cargo," said co-founder Santiago Brent.
Born in a Rice Design Lab
Haast is a homegrown Houston robotics story. Co-founders Ege Halac, Jason Chen, and Santiago Brent — all graduating seniors — developed the prototype at Rice University's Oshman Engineering Design Kitchen (OEDK), the hands-on engineering studio where Rice students build real hardware. The venture took shape through the Liu Idea Lab for Innovation and Entrepreneurship's Summer Venture Studio, with a supporting team of Rice researchers.
The traction has been quick for a company this young: Haast won Best Aerospace or Transportation Technology at the 2026 Oshman Engineering Design Showcase and performed strongly in the 2026 Napier Rice Launch Challenge before closing its pre-seed round. The team is targeting pilot trials in 2027, with initial market entry later that year.
Why Houston Is the Right Place for It
Few cities are better suited to prove out medical drone delivery than Houston. The Texas Medical Center is the largest medical complex in the world — a dense cluster of hospitals, research institutions, and specialty centers that constantly move biological material between facilities. That's exactly the network a medical drone service needs: many high-value delivery points, close enough together to be within drone range, where speed and cargo integrity translate directly into patient outcomes.
Haast also sits at the intersection of two things Houston does well. The medical side is obvious. The autonomous-aircraft side connects to the region's deep aerospace and drone expertise — the same Gulf Coast ecosystem that flies inspection drones over energy infrastructure and builds robotic mechanisms for lunar landers. A medical delivery drone is, at its core, an autonomous robot that has to navigate, carry a precious payload, and land safely every time.
The Bigger Picture
Medical drone delivery has been an aspiration for years, with the hard problems being regulation, reliability, and the cargo-handling details that determine whether the medicine actually survives the trip. Haast's bet is that solving the sensitive-cargo problem first — the climate-controlled bay, the chain-of-custody software, the medical-grade reliability — is what turns a flashy demo into a real service that hospitals will trust.
It's also a reminder of where a lot of Houston's next robotics companies will come from: university design labs and student teams. A drone that started as a Rice engineering project is now a funded company aiming to move organs across the city faster than a ground courier ever could. That pipeline — from campus makerspace to venture-backed startup — is exactly what a healthy regional robotics ecosystem looks like.
