How we work

  1. 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.

  2. Talk to the people doing the work

    You meet named engineers and designers. There is no account manager translating technical questions in both directions.

  3. 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.

  4. You own everything

    Repository, cloud account, domains and credentials stay yours. We work in your accounts wherever possible.

Why Three Index

Founded in 2020 in Ahmedabad, Gujarat. Fifty-plus IT professionals. More than five hundred projects shipped across product and enterprise work.

We are large enough to staff serious products and small enough that the people who wrote a module can still explain it. See how we operate, browse case studies, or join the team.
