New era of building
You vibe-coded the product. We’ll make it hold.
Built it with Claude, Cursor, Antigravity, or another AI tool? We audit the project, give you a solution architect’s read on scale, and add the features the prompts keep missing.
How we work
-
Scope before code
We write what is being built, what is excluded, integrations, dates and cost basis before the build starts. Changes get quoted before they get coded.
-
Talk to the people doing the work
You meet named engineers and designers. There is no account manager translating technical questions in both directions.
-
Working software every two weeks
Increments land on staging you can open and use. Progress you can click on beats progress in a status report.
-
You own everything
Repository, cloud account, domains and credentials stay yours. We work in your accounts wherever possible.

Is Three Index related to three-fund or three-index investing?
No. Three Index is a software development company. Search results for 'three-index' or 'three index' often refer to three-fund investment portfolios or mathematical three-index problems. Those topics are unrelated to Three Index at threeindex.com — the AI-first software company in Ahmedabad.

Browse services at threeindex.com/services, industry pages and anonymised case studies (including healthcare and real estate), the company FAQ, and the blog.

What engagement models do you offer?
Fixed-scope projects when outcomes and integrations are clear enough to quote; dedicated teams when priorities shift week to week; and design-then-build when product and interface work should come before engineering. We recommend the shape that matches how you want to buy delivery.
