ACTOL was founded to advance India's self-reliance in mission-critical unmanned systems under the Make in India initiative.
Formed as a joint venture between Tolle Labs and ACCID Technologies, the company focuses on indigenizing critical drone and autonomy components. Our work centers on secure communications, flight electronics, and next-generation unmanned subsystems. We aim to build trusted, sovereign technologies for defence and strategic applications.
Because critical systems must be engineered at home, controlled at home, and built to last.
