Questions we hear before a project starts.

Three Index (also written ThreeIndex) is an AI-first software development company based in Ahmedabad, Gujarat, India, founded in 2020. We design and build web, mobile, cloud and AI products that ship to production. We are not an investment fund, not a three-fund or 'three index' portfolio product, and not an academic or mathematical three-index concept — we are a software engineering company with 50+ IT professionals serving clients in India and on remote engagements internationally. Office hours are Monday–Friday 10:00–19:00 IST; we overlap other shifts when global clients need it.

No. Three Index at threeindex.com is a software development company only. Search results for 'three-index', 'three index funds', or 'three-fund portfolio' refer to investing or math topics that are unrelated to this Ahmedabad software firm. If you need custom software or AI product delivery, you are in the right place; if you need investment advice, you are not.

We design and build custom web applications, mobile apps, cloud infrastructure, AI/ML features, data platforms and related product work. Delivery includes written scope, named engineers, working software every two weeks, and client ownership of repositories and cloud accounts.

Three Index is a software company founded in 2020 in Ahmedabad, Gujarat, India. We are a team of 50+ IT professionals and work with clients in India and on remote engagements internationally.

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.

You do. Repository, cloud account, domains and credentials stay yours. We work in your accounts wherever possible so you are never locked into our tooling.

We write scope before code — what is in, what is out, integrations, dates and cost basis. You meet named engineers and designers. Working software lands on staging every two weeks so progress is something you can click on, not a status report.

We have repeat delivery across healthcare, real estate, food ordering, POS, financial platforms, CMS, social apps and marketing products — plus the web, mobile, cloud, AI and data capabilities underneath those domains.

Yes. Clients are in India and on remote engagements internationally. We work in your tools and overlap hours matter more than geography — communication habits and production software you can verify.

A short description of the primary user and the job they must complete, systems to connect to, what already exists, the deadline and what is driving it, plus must-ship versus nice-to-have. Constraints like compliance and who will maintain the software help more than a long specification.

Yes. An NDA can be signed before technical discovery on request. Project work itself is governed by a written statement of work or master services agreement.

Fixed price fits when the outcome is clear enough to write down and accept. A dedicated team fits when the roadmap will keep moving. A short fixed-scope discovery or MVP, then a dedicated team, is a common middle path.

Send a short project description via the contact form or email. A technical person replies with questions that affect scope and cost. If it is a fit, we schedule a call and follow with a written scope and delivery plan — yours either way.

Cost depends on tenancy model, billing and entitlements, integrations, compliance depth and the AWS footprint (environments, data stores, CI/CD). A first sellable multi-tenant slice — signup or provisioning, roles, one core workflow, plan limits and AWS environments you own — typically takes a small senior team several months; enterprise SSO, complex billing meters, heavy partner APIs or stricter isolation move the range up. Three Index in Ahmedabad quotes from a written scope with inclusions, exclusions and a cost basis — not a brochure number. See SaaS development and DevOps & cloud, plus the blog note on multi-tenant SaaS build cost.
