Almost every ranking of Argentine software companies has the same problem: it's built for a corporation, not for a small business. It lists companies with thousands of employees whose minimum engagement is far above what a thirty-person company can or should spend, and it sorts them by revenue, which is a metric about the vendor and not about you.
This list is built the other way around: the criterion is which of these companies will actually take care of you if your project is worth between USD 5,000 and 40,000. If you're in the US and looking at Argentina because of the timezone overlap, that's the question that decides the outcome — not which firm is biggest.
How this list is built
No invented scores. Five criteria, all of them verifiable by you before you sign:
- That they take projects your size. Plenty of good companies have a minimum engagement that rules you out, and it's better to know beforehand.
- That there's someone technical to talk to, not only an account executive relaying messages.
- A clear contracting model —fixed price, hour bank or staffing— stated up front.
- Verifiable work, with references you can actually call.
- Continuity: that they'll still be around next year to maintain what they built.
One disclosure: Atomix Code, which publishes this blog, is on the list. It's marked where it belongs and you can discount it from the criteria. We'd rather include it and say so than leave it out and pretend to be neutral.
The order isn't best to worst. It's smallest to largest, because the size of the vendor is the best predictor of whether your project will matter to them.
Boutiques and small teams
Ten to forty people. You work with the people who write the code. It's where a small-business project lands best.
1. Atomix Code
(We publish this blog.) Custom business systems, apps and platforms with scope and price closed before we start and delivery in under a month. The model is a fixed price against a defined scope, not an hour bank.
Who it's for: small companies that need a system of their own and a budget that doesn't move.
When not: if you need to add ten developers to a team of yours, that isn't the model.
2. 10Pines
An Argentine cooperative, with a lot of weight in the local agile development community. Team-based work and a stated, public engineering culture.
Who it's for: products that will evolve over years and value engineering quality.
When not: if you're looking for the lowest price on the market.
3. NaNLABS
A digital product boutique focused on application development and work with US clients.
Who it's for: a new product that has to be designed as well as coded.
4. Siete Ideas
An Argentine development and product studio, oriented to small-business-scale projects.
Who it's for: contained builds with close, hands-on support.
Mid-size
Fifty to three hundred people. Structure, processes and separate departments. More predictability, less direct access to whoever is coding.
5. Incluit
A Buenos Aires company with two decades in the market and projects of varying size, domestic and international.
Who it's for: companies that want a vendor with structure without going to a multinational.
6. Vates
Software development and technology integration, with a presence in Argentina and the United States and strong QA work.
Who it's for: projects with formalized testing and quality requirements.
7. Flux IT
An Argentine digital products and services company, with multidisciplinary teams.
Who it's for: product projects that need design, development and data together.
8. IT Oeste
A Buenos Aires software company focused on custom development, apps and web platforms for local companies.
Who it's for: work anchored in Argentina, where being in the same city as the client is part of the point.
Large
Three hundred people and up. Excellent in their tier and almost always oversized for a small business. They're here so you know where the line falls.
9. Baufest
An Argentine software consultancy with decades in the market and a focus on large organizations.
Who it's for: companies with their own IT departments and long-term projects.
When not: a small-business management system isn't their project size.
10. Globant
Founded in Argentina, today a global, publicly traded company. Digital transformation programs for corporations.
Who it's for: large organizations with seven-figure annual budgets.
When not: in almost any small-business case. That isn't a criticism: it's a different category of service.
Who isn't here, and why
The staff augmentation companies —BairesDev is the best-known example— were left out on purpose. They don't sell finished projects: they rent you people for you to direct. It's a valid model and a very good one if you have a technical lead of your own, but it isn't the same as buying a system, and mixing the two in one list muddles the decision.
Marketing agencies that also code. If your project is a brochure site, they can be the right and cheaper option. If it's a business system, no.
The ones that no longer exist as such. The Argentine market has seen several significant acquisitions in recent years, and there are rankings floating around that still list companies which today are part of another one. Check that whoever is quoting you is still who you think they are.
How to use this list
Don't call all ten. Do this:
- Place your tier by budget: up to USD 10,000, look at the first block; between 10,000 and 40,000, the first and the second; above that, the third as well.
- Ask for three quotes inside the same block. Comparing a boutique against a large consultancy isn't comparing: they're different services at prices that don't touch.
- Ask for the scope in writing before the number. A quote with no scope document can't be compared against another one.
- Call two references for each. It's the half hour that saves you the most money in the whole process.
