Customsoftware,ready tomonetize.
Technology experts and lawyers on one team. We build your app or platform and handle the legal side, so you can sell it, license it or raise capital with no surprises.
What usually goes wrong, and how we prevent it
If you've hired a software team before, some of these will sound familiar. If this is your first project, these are the ones to avoid.
The code isn't in your name
You paid for the build, but nobody put in writing who owns the software. Selling it, licensing it or showing it to investors gets complicated.
How we solve it: Yours or licensed, in writing
We assign you the rights to the software or grant you a license, depending on your business model. It's in writing from day one, so you know exactly what you can do with it.
Budgets and timelines spiral
The project starts without a clear scope, and every week something new comes up that costs more and pushes delivery back.
How we solve it: Clear scope before we start
You know what will be built, in what order and what it costs. Then frequent releases you can test: you see real progress, not reports.
You talk to a salesperson, not the builders
Your ideas pass through several hands before reaching the technical team, and details get lost along the way.
How we solve it: Talk to the people writing the code
No middlemen: you deal directly with the team designing and building your project.
Off-the-shelf software makes you adapt
You end up bending your operation to a tool that wasn't made for you, or patching the gaps with spreadsheets.
How we solve it: Built around how you operate
We start from your processes, rules and integrations, so the system fits your business, not the other way around.
Legal comes late, or never
The software ships without contracts, terms or a privacy notice, and the gaps show up right when you want to sell it, license it or raise capital.
How we solve it: Lawyers on the same team
With ANBEC Abogados we prepare contracts, licenses, terms, the privacy notice and registration filings with INDAUTOR and IMPI while we build.
The system can't keep up as you grow
More users, more data or one new feature, and something gives. Nobody wants to touch the code for fear of breaking it.
How we solve it: Built to grow
Architecture and tests designed so the system holds up to what's next, with support and improvements as your business grows.
What we build
One team for the whole journey: product, design, code, infrastructure and the legal side.
Systems built around how your company actually runs: processes, rules and integrations no off-the-shelf product handles.

Usually one team builds the software and another handles the legal work, and details fall through the cracks. Here lawyers and technology experts work on the same project, so what gets built and what gets signed say the same thing.
- Assignment of rights or software licensing
- Development, maintenance and SaaS agreements
- Terms of service and privacy notice
- Software copyright (INDAUTOR) and trademark (IMPI) registration in Mexico
- Monetization models: licenses, subscriptions and resale
