YES!Delft, the tech incubator on the TU Delft campus, announced its autumn 2025 Validation Batch on 29 September 2025, with HeatLift Dynamics — now Expantec — among the selected start-ups.
The programme comes with an office in the YES!Delft building at Molengraaffsingel 12, an ecosystem of fellow start-ups, service partners and mentors, and a structured route to validating the business with real customers. Both co-founders have worked from here full-time since September 2025.
