Tamil Nadu Hardware Accelerator for Prototype and Product (TN-HAPP), branded as iAccelerate 4.0, is a 12-week intensive and structured hybrid accelerator programme designed to help hardware startups in Tamil Nadu move from concept stage to production-ready products.
The program is implemented by Tamil Nadu Technology Hub (iTNT Hub) and focuses on providing government-subsidized access to professional design, prototyping, and manufacturing ecosystem support. Selected startups are onboarded into a cohort-based accelerator where they receive structured mentorship, design validation support, and connections to MSME manufacturers and industry partners.
The accelerator operates through two dedicated tracks aligned to Technology Readiness Levels (TRLs), enabling startups at both early and advanced hardware development stages to participate. Financial support is provided in the form of government-backed design vouchers that can be redeemed with iTNT Hub empaneled design and manufacturing partners. The program aims to reduce product development risk, accelerate go-to-market readiness, and enable scalable manufacturing outcomes for hardware startups.
