DheyaTech, a deeptech startup founded by engineers who spent a combined fifteen-plus years at GE Aviation and Rolls-Royce, has raised Rs 43 crore in a pre-Series A round led by Avaana Capital, with participation from Unimech Aerospace and Manufacturing. The company builds small gas-turbine engines spanning 20 to 400 kgf of thrust for advanced aerial mobility and energy applications, with fuel-flexible and hydrogen-capable variants aimed at both propulsion and power generation. The capital will fund production scale-up, a new integrated testing facility, and deployment work with domestic and global customers ahead of flight trials targeted for later this year.
The technology story is genuinely strong - engines this small, built domestically, with hydrogen flexibility baked in from the start, sit in a category India has almost entirely imported until now. But the harder part of DheyaTech’s next two years isn’t engineering. It’s convincing buyers who have only ever trusted foreign nameplates on this exact category of hardware to put a first-time domestic supplier into their own supply chain.
Deeptech hardware sells differently than software
A software buyer can trial a product for a month and walk away with limited cost if it fails. A buyer integrating a gas-turbine engine into an aircraft, a drone platform, or a power system is signing up for years of dependency on that supplier’s quality control, spare parts, and support - failure isn’t an inconvenience, it’s a safety and mission risk. That buyer doesn’t evaluate DheyaTech the way a software customer evaluates a new vendor. They evaluate it the way a defense procurement officer evaluates anyone: on track record, on who else has already trusted it, and on what happens if something goes wrong at 10,000 feet. A funding round barely moves that needle on its own.
Why the founders’ pedigree is doing more work than the cheque size
Rs 43 crore is a modest number against what deeptech hardware companies eventually need to scale manufacturing. What it buys DheyaTech now is less about runway and more about a credible signal to a skeptical buyer: engineers from GE Aviation and Rolls-Royce didn’t join an unproven startup on a whim, and an institutional investor with deeptech conviction underwrote that bet after diligence a typical buyer can’t replicate themselves. In a category where reputation is the actual product being sold alongside the hardware, that borrowed credibility is doing more commercial work in the near term than the capital itself.
The real test is the first confirmed customer, not the first engine
DheyaTech reportedly already has orders in place ahead of flight trials, which matters more than any spec sheet, because in import-substitution hardware the entire sales motion runs backward from most startups’ - the first real customer is the actual proof of the product, and every customer after that is buying partly because the first one did. A gas turbine that performs perfectly in a lab test still has to survive its first public failure, if one comes, without taking the company’s credibility down with it. That’s the real risk this raise is underwriting: not whether the engineering works, which by every account it does, but whether a market trained for decades to default to imported names is willing to bet its own supply chain on a first-time domestic one.
