7DayLabs / services
Most agencies quote 8 to 12 weeks and an estimate that doubles midway. 7DayLabs runs a fixed 7-day sprint at a fixed price: Rs 1,99,999 for a working product with real code, database, authentication, and deployment. Founders use it to validate with real users before committing to a bigger build.
Design, development, database, authentication, deployment, source code with complete IP transfer, technical documentation, and three days of post-delivery bug fixes. Web apps ship in React; mobile ships in Flutter or React Native (or native Swift/Kotlin when it is the right call).
Who builds it: the sprint is led by a Google Developer Expert who started India's Flutter movement, built apps used by millions, and runs a 300K+ developer community. No outsourcing chain, no junior hand-offs.
For an MVP, yes, if scope is honest. The consultation cuts the idea to the core loop that proves demand. Features beyond the core are phased into follow-up sprints. Complex products get a custom timeline up front instead of a blown deadline later.
