What it is
build3's ten-week impact accelerator for founders at the minus one to one stage whose businesses push progress on at least one UN Sustainable Development Goal. It runs mostly online, with daily two-hour live sessions every weekday and two in-person bootcamps in Goa.
What you get
A 25 lakh rupee investment is available to selected startups after the programme, via a final presentation to build3's investment committee. build3 publishes the terms in full: no upfront dilution and no valuation set by build3, with 1.5 percent equity that converts only at the next round, at a 15 percent discount, or against a 5 crore rupee valuation floor if no round is raised in three years. A founder building a lifestyle business can return 2.2 times the invested capital within five years and take back full ownership. The programme itself also includes one-to-one mentorship from operators and investors, bi-weekly masterclasses, demo days across India with VCs, family offices and angels, and up to 24 months of ongoing support. The programme fee is 39,900 rupees, plus 5,900 rupees per additional co-founder.
Cohort
build3 states that around 3,000 founders apply each cohort and it builds with 70.
Who it's for
Impact-driven startups from idea to functional early stage, anywhere on the minus one to one spectrum, whose work benefits people and the planet. Selection runs through an application, then a three-stage evaluation on compatibility, capability and commitment, including an interview and a reference check.
Programme dates
The next cohort starts on 16 November 2026, and build3 states that applications close on 15 October.
