A startup looking for an MVP development company has a problem an established business doesn't: it doesn't know yet what needs to be built. It will find out while building it, and that rules out most of the companies on the general rankings from the start, because they're set up to execute a scope that's already defined.
Below are five Argentine options for founders in the US who want a nearshore team in a close timezone, chosen with that criterion in mind and not by size.
What a startup needs that an established company doesn't
These are the four criteria behind the list. They're different from the ones you'd use for any other project.
- Speed to the first version. It doesn't matter how many developers they have. What matters is when there's something real in front of users.
- Willingness to say no. The vendor that accepts everything you ask for is the one that will burn through your runway building features nobody is going to use.
- Code another team can pick up. If the round closes, you'll hire your own team, and whatever was left behind has to be something they can take over.
- A contracting model that doesn't demand certainty you don't have.
Atomix Code, which publishes this blog, is on the list and marked as such. Discount it from the criteria as you see fit.
Five MVP development companies for startups
1. Atomix Code
(We publish this blog.) An MVP with scope and price closed up front and delivery in under a month. The approach is to cut the first version down to what can be validated and leave everything else out explicitly, in writing. How that cut works is covered in what makes the cut in a 30-day MVP.
Who it's for: founders who need to ship something real on a budget that doesn't move.
When not: genuine technical research, where nobody can estimate. A fixed price protects no one there.
2. NaNLABS
A product boutique with sustained work for US clients and a stated focus on the definition stage, not just on writing code.
Who it's for: a new product where product design is half the problem.
3. 10Pines
An Argentine cooperative with a public engineering culture and long experience on products that keep evolving for years.
Who it's for: when you've already validated and the next step is building something that will last, and building it well.
When not: if you need a throwaway first version next week.
4. Siete Ideas
An Argentine product development studio, with contained project sizes and a close working relationship.
Who it's for: first versions with hands-on support.
5. Flux IT
An Argentine digital products company with teams that combine design, development and data.
Who it's for: when the product already has traction and needs to scale with some structure.
Who was left out, and why
The large firms. Globant, Baufest and the like do what they do very well, and this isn't it. Their minimum engagement would eat an entire seed round, and their processes are designed for projects with a defined scope and approval committees. If you want to see where each tier of the Argentine market sits, there's a map of nearshore software development in Argentina.
Staff augmentation. BairesDev and similar models rent you developers for you to direct. If you have a CTO, that can work very well. If the technical team is what you're hiring, there's nobody to direct them.
Agencies that bill by the hour with no cap. For a startup with a counted runway, a model where the vendor has no financial incentive to finish is the worst of both worlds.
The mistake that keeps repeating
The most expensive mistake isn't picking the wrong vendor. It's asking for the full version.
A founder shows up with a list of twenty-five features, because those are the ones the finished product needs. The vendor quotes all of them, it comes out to four months and three times the budget, and the product reaches the market knowing exactly what it knew at the start, with less money left to react.
What works is the reverse: pick the one thing you need to find out and build the minimum required to find it out. If your hypothesis is that people will pay to book appointments online, you don't need user profiles, notifications, an analytics dashboard or a mobile app. You need people to be able to book and pay.
Everything else is a bet on a product you don't yet know anyone wants.
Three things to settle in the contract
These are the ones you can't negotiate later, and they decide whether the build was an investment or a rental.
- Code ownership. Yours, in a repository under your name, from the first commit, not handed over at the end.
- Accounts in your name. Hosting, domain, app stores, third-party services. All of it with your email and your card.
- What happens if the round doesn't close. How the project winds down, what gets delivered and in what state.
That last conversation is uncomfortable to have at the start and very expensive not to have.
