Hero Electronix's Tessolve Raises $75 Million From Vector Line Capital to Buy Its Way Up the Chip-Design Value Chain

Tessolve Semiconductor, the Bengaluru-headquartered chip engineering company owned by Hero Electronix, has raised $75 million in a round led by US investor Vector Line Capital. The deal, reported on October 12, 2026, comes barely a year after Tessolve raised $150 million from TPG, and it is earmarked mainly for acquisitions.

For Vector Line — a firm that invests specifically in semiconductors and the chip supply chain — this is its first investment in India. It joins TPG and Novo Tellus as backers of the company.

The deal in brief

• Amount: $75 million, led by Vector Line Capital.
• Purpose: primarily acquisitions, along with expansion of Tessolve's offerings.
• Pipeline: the company says it is in advanced discussions with several potential targets and aims to complete transactions over the next couple of quarters. It has not named the targets or disclosed deal terms.
• Previous round: $150 million from TPG in September 2025, billed at the time as the largest fundraise by a semiconductor engineering services company in India, and intended for delivery centres, test labs and acquisitions.

Who Tessolve is

Tessolve offers turnkey engineering across the chip lifecycle — architecture, design, verification and validation, post-silicon testing and embedded systems. It employs more than 3,500 engineers across 10 countries and runs a network of test laboratories worldwide (reports put the number at nine to eleven). Hero Electronix, the electronics arm of the Hero group, entered the semiconductor business by acquiring Tessolve in 2016.

Co-founder and CEO Srini Chinamilli has described the company's trajectory as a move from offering silicon test engineering services towards designing and developing complete chips for customers, including businesses building AI infrastructure. In an earlier interview, he said Tessolve was in talks to acquire two firms — one in the US and one in India — and aimed to cross $500 million in annual revenue within three to four years.

Why acquisitions, and why now

Engineering services firms such as Tessolve sit at an important junction in the semiconductor industry. Global chip companies — particularly fabless designers — outsource large chunks of design verification, physical design, test program development and characterisation work. India already hosts a very large share of the world's chip-design engineers, much of it in captive centres of multinational companies. What it has lacked is a set of home-grown firms that own customer relationships, intellectual property and test infrastructure at global scale.

Buying smaller specialist firms is the fastest way for a services company to add capabilities it does not have — a particular design flow, an analogue or RF specialism, a customer base in a new geography — and to move from billing hours towards delivering complete silicon. Two large rounds in roughly 13 months suggest investors see Tessolve as a consolidation platform in a fragmented market.

The timing also fits India's broader semiconductor push. With the government backing fabs and assembly-and-test plants under the India Semiconductor Mission, and the Union Cabinet having approved a second phase of support, the country needs not only factories but also engineering companies that can take chips from specification to production-ready silicon. Design and test capability is the part of the value chain where India already has depth; scaling firms like Tessolve converts that talent base into companies with global reach.

What it means for India's chip ecosystem

Vector Line's arrival is a signal in itself. Specialist semiconductor investors have so far mostly engaged with India through multinational companies' local operations. A dedicated chip-focused fund making its first Indian bet on an India-headquartered engineering firm suggests the country is being viewed as a place where semiconductor companies — not just engineering centres — can be built.

For the wider ecosystem, a larger Tessolve could mean:

• More test infrastructure located in India, useful for domestic chip start-ups that otherwise have to send silicon abroad for characterisation.
• A deeper bench of senior engineers who have worked across full chip programmes, which is the profile most Indian product start-ups struggle to hire.
• An Indian acquirer for smaller design-services firms, giving founders in that space an exit route at home.

What to watch

The key indicators over the next two quarters will be the acquisitions themselves — their size, geography and technical focus — and whether Tessolve begins to announce full-chip or turnkey ASIC programmes rather than service engagements. Its stated ambition of $500 million in annual revenue would put it among the largest independent semiconductor engineering firms headquartered in Asia.
