Tessolve Post-Funding Expansion Builds India's First Full-Stack Semiconductor Services Company
Tessolve, the Bengaluru-based semiconductor design and test services company, is executing its most ambitious expansion following the closure of its USD 75 million growth equity funding round. The expansion adds 1,200 engineers across Bengaluru and Hyderabad over eighteen months, covering chip design and verification services, physical design and layout, embedded firmware development, and a new category for the company: automated test engineering for OSAT customers. The funding also supports the establishment of a new test services division equipped with ATE systems capable of handling RF, mixed-signal, and high-speed digital devices, extending Tessolve's service scope from design-side services into the production testing that is part of the OSAT process flow. With design, verification, physical implementation, firmware, and test all under one roof, Tessolve is positioning itself to offer semiconductor customers the full service spectrum from chip design initiation through volume production test, a scope that no other India-based services company currently covers.
ATE Investment and the RF Test Opportunity
The automated test equipment investment is the most capital-intensive element of Tessolve's post-funding expansion and represents the company's entry into a business model that is fundamentally different from its existing design services practice. Design services revenue is earned through engineering time and IP delivery, while ATE test services revenue comes from machine time and test programme execution, creating a more capital-intensive but more scalable revenue model with higher barriers to entry. Tessolve is investing in ATE systems from Teradyne and Advantest capable of testing RF front-end modules, mixed-signal ICs, and high-speed digital devices including DDR memory interfaces and SerDes circuits. The RF test capability targets the India market for mobile and wireless chip testing, where the growth of India's smartphone electronics manufacturing base is creating demand for domestic test capacity that is currently met almost entirely by imported test services from Southeast Asian OSAT facilities.
Automotive Services Entry and ASPICE Certification
Tessolve's entry into the automotive semiconductor services market involves both design services for automotive chip projects and automotive process certification. The company is pursuing ASPICE (Automotive SPICE) process assessment and ISO 26262 functional safety management certification, which are prerequisites for engineering service providers working on safety-relevant automotive chip designs. With these certifications, Tessolve will be able to accept design and verification work packages from Tier-1 automotive semiconductor suppliers under their supplier quality management requirements, opening a market segment that is growing rapidly as India's automotive electronics supply chain deepens. The automotive services team being built at Hyderabad specialises in safety-critical verification methodologies, hardware security module design review, and the documentation and traceability requirements of automotive development processes.
India's Semiconductor Services Ecosystem and Tessolve's Position
India has a large and well-established semiconductor design services industry, with companies including Tata Elxsi, QuEST Global, Cyient, and numerous smaller specialists providing design and verification services to global semiconductor companies. Tessolve's post-funding positioning as a full-stack provider from design through test addresses a gap in this landscape by combining the design services strength that India companies have traditionally offered with the test engineering and ATE services capability that has been less developed in India. The company's growth comes at a time when Indian semiconductor services companies are competing more aggressively for design work programmes that were previously executed in Taiwan or the United States, and when the establishment of domestic OSAT facilities is creating demand for integrated test services that can be provided locally rather than requiring shipment of wafers to offshore test facilities.
