What an MVP is, and what it isn't
A minimum viable product is the smallest version of your product that lets real users do the one thing it exists for, so you can learn whether they care. It is not a prototype that falls over, and it is not a stripped-down copy of your full vision with every feature at half quality.
The aim is learning per rupee spent. A good MVP is narrow, works properly and is built on foundations you won't have to throw away.
How to scope the core feature set
Start with the single job the product does and the type of user who most needs it. List every feature you can imagine, then cut anything that isn't needed for that user to complete that job once. What remains is your first release.
Cut ruthlessly but keep the basics that build trust: sign-in, sensible error handling and security. Skipping those costs more later than building them now.
SaaS architecture choices that are hard to undo later
A few early decisions shape how easily a SaaS product grows: how customers' data is separated (multi-tenancy), how users and roles are modelled, how billing and plans are handled and how the system is monitored. None of this needs to be elaborate on day one, but it should not be accidental.
We favor a simple, well-structured codebase on proven tools, so you can add features quickly now and scale parts of the system independently when real usage demands it.
What happens after launch
Launch is the start of learning. We help set up analytics and feedback so you can see which features users reach, where they drop off and what they ask for.
From there you decide: iterate on what works, change direction or stop. A well-run MVP makes any of those decisions cheaper and better informed.
