BIRAC vs SISFS vs a state grant: which non-dilutive scheme actually fits my startup?
The short answer
Match the scheme to what you're building, not to whichever form you found first. BIRAC (BIG, SEED, LEAP) is the right door for biotech, healthtech, and deep-science where you have a lab-provable innovation. SISFS is for early software or product startups needing proof-of-concept or market-entry cash through an incubator. State schemes (Kerala, Karnataka, Gujarat, Telangana) are fastest when you're physically based there and want smaller, quicker grants. Apply to the one where your story is the obvious fit, and stop spraying identical applications everywhere.

Why we picked it
This is the side-by-side you actually need before you write a single application: 30+ Indian schemes with ticket size, eligibility, and a sector-to-body map that tells you biotech goes to BIRAC, defence to iDEX, and software proof-of-concept to SISFS. It also stages the grants (idea, prototype, scaling) so you stop applying to a scheme meant for a stage you are not at.
Match by sector and stage: BIG (up to 50 lakh) for lab-provable biotech, SISFS (up to 20 lakh grant plus 50 lakh debt) for early software/product via an incubator, state schemes (Karnataka Elevate up to 50 lakh, TANSEED up to 10 lakh) when you are physically based there
SISFS caps you at 10 lakh of prior central/state government funding, so sequence it before or without heavy grant stacking
Sector determines the door more than the form: defence goes to iDEX, deep-tech to BIRAC/MeitY, generalist software to SISFS
Why we picked it
The official BIG page, not a blog paraphrase: up to 50 lakh grant-in-aid over 18 months, calls opening 1 January and 1 July each year for roughly 45 days, and the hard gate most founders miss, that you need a registered company with a functional R&D lab (or incubatee status) to even be eligible. If your innovation is lab-provable biotech, healthtech, or agri-biotech, this is your obvious fit, and prior BIG grantees cannot reapply.
Why we picked it
The clearest single-page explainer of the SISFS mechanics that trip founders up: you never apply to DPIIT directly, you apply to up to three empanelled incubators, and the money splits into a non-dilutive grant (up to 20 lakh for proof of concept or prototype) plus repayable/convertible instruments (up to 50 lakh for scaling). It spells out the 51% Indian shareholding rule, the under-2-years incorporation cap, and the 10 lakh prior-funding ceiling in one place.
