What is TRL (Technology Readiness Level) — and why does it matter for your Startup?

If you've ever pitched to an investor or applied for a government grant (RDI Funds), someone has probably asked — "What TRL are you at?"

Most founders fumble this question. Not because their technology isn't good, but because they've never had a proper framework to evaluate it.

TRL Levels

TRL, or Technology Readiness Level, is a 9-point scale that measures how mature your technology is — from a raw idea (TRL 1) all the way to a fully deployed, commercial product (TRL 9). Originally developed by NASA in the 1970s, it is now used by governments, investors, research institutions, and corporates worldwide to evaluate innovations in a structured, evidence-based way.

In India, NRDC has launched NETRA — a dedicated facility that formally certifies technologies on the TRL scale. A NETRA certification can significantly strengthen your position when approaching investors, applying for government grants, or negotiating licensing deals.

So what does a TRL assessment actually look at?

It's not just about what you've built. A proper assessment covers five dimensions — the scientific foundation of your technology, the prototype or build you've developed, how and where it's been tested, the strength of your IP and documentation, and early signals of commercial viability. Each of these tells a different part of the story.

The difference between TRL 3 and TRL 4, for instance, is the difference between a concept that works on paper and one that has been physically demonstrated as an integrated system. That gap matters enormously when it comes to funding eligibility and investor confidence.

Knowing your TRL helps you identify exactly what's missing, prioritise your next steps, and communicate your technology's maturity in a language that serious stakeholders understand.
