How to Choose an MVP Development Company

MVP partners should also assist in selecting features that need to be part of the initial release and which can be postponed.

First, consider how the company conducts the discovery process, how it defines requirements, prioritizes functionality, and identifies the technical risks before development.

Experience in the industry is equally important; an MVP in FinTech will involve some payment processing functionality and security features, whereas a marketplace will have its own list of required features like user roles, listings, search, transactions, and processes for buyers and sellers.

Lastly, think about the future after the MVP launch – when the MVP takes off, it would be easier for the development team to scale the product without re-architecture.

Final Thoughts

The goal of the MVP is not just about creating a small product. The goal of the MVP is to test a key business hypothesis with real people and then invest in the findings. Cleveroad, Altar.io, S-PRO, thoughtbot, Cheesecake Labs, Purrweb, and SolveIt all offer unique skills in product strategy and engineering. Consider how they stack up against the hypotheses you need to prove out.
