A small, serious team for important products.

TekRabbits is a Kolkata-founded engineering and technology company built around one promise: move with speed, keep the thinking rigorous, and deliver work people can depend on.

Our story

Innovation should move at the speed of imagination.

Founded in September 2025 in Sodepur, Kolkata, by Subhrajit Bhattacharjee and Pratik Kumar Sinha, TekRabbits was created to bridge the gap between bold ideas and real-world products.

Our work sits at the intersection of electronics, intelligence, and design. We help teams move from concept exploration and system architecture through prototyping, testing, certification support, and scalable production.

Our north star

Rapid. Reliable. Remarkable.How we think, design, build, and deliver

How we work

Precision is a team sport.

Cross-disciplinary by default Hardware, firmware, mechanical design, connectivity, and intelligence are considered together.
Agile without being careless We shorten feedback loops while preserving the discipline needed for performance, compliance, and reliability.
Built for the next handoff Good engineering makes the next decision easier for your team, your manufacturer, and your customers.

Leadership

Experience that stays close to the work.

The founders bring complementary strengths across operations, manufacturing, product architecture, firmware, and intelligent systems.
