iAccelerate 4.0 – Tamil Nadu Hardware Accelerator for Prototype & Product Startups

iAccelerate 4.0, also known as the Tamil Nadu Hardware Accelerator for Prototype and Product (TN-HAPP), is a 12-week hybrid accelerator programme designed to help hardware startups in Tamil Nadu move from concept to production-ready products. The programme is implemented by the Tamil Nadu Technology Hub (iTNT Hub) and provides government-subsidized access to professional design, prototyping, and manufacturing ecosystem support.

Selected startups join a cohort-based accelerator offering structured mentorship, design validation support, and connections to MSME manufacturers and industry partners. The accelerator runs two dedicated tracks aligned with Technology Readiness Levels (TRLs), enabling both early-stage and advanced hardware startups to participate. Financial support comes in the form of government-backed design vouchers redeemable with iTNT Hub empaneled design and manufacturing partners. The goal is to reduce product development risk, accelerate go-to-market readiness, and enable scalable manufacturing for hardware startups.
