Pre-seed investment opportunity in compact geothermal drilling technology

About

Flexdrill is developing a compact drilling system for ground source heat pumps in residential areas.

Today, geothermal drilling is expensive, complex, and often not possible in small or hard-to-access properties. This is a major barrier to wider adoption.

Flexdrill reduces equipment size, simplifies operation, and enables drilling in locations where conventional rigs cannot operate.

The system is currently in development, with prototypes built and a full-scale system in progress. First field tests are planned for summer 2026, with the goal of reaching a market-ready product by early 2027.

We are raising pre-seed funding to complete development and validate the system in real projects.

We are looking for investors with experience in hardware, energy, or construction who want to support an early-stage product with a clear market need.
