Custom software development.
Web platforms, internal portals, and tools your business needs that do not exist outside of it. We quote by scope and deliver on a date.
Most companies reach the same point: the process that makes them different no longer fits in a spreadsheet, and no off-the-shelf tool solves it without forcing them to change how they work. That is when building something of your own starts to make sense.
Molecula Digital is a software development agency based in Mexico. We work with companies that already have operations and need a tool built for them, and with founders who need to put a product in front of real users before investing in an in-house team.
What we build
Web platforms and portals
Systems with users, roles, and data: customer portals, internal operations dashboards, catalogs, management platforms. Anything where several people log in, see different things depending on their role, and leave a record of what they did.
Internal tools
The system that currently lives spread across spreadsheets, WhatsApp groups, and two people’s memory. We turn it into a tool with one source of truth, clear permissions, and reports that generate themselves.
Digital products and MVPs
For founders who need to validate before hiring. We build the smallest version that is already useful for getting users and learning from them, with enough architecture that growing later does not mean starting over.
Integrations and APIs
Connecting your software to what you already use: invoicing, CRM, payment gateways, ERP, WhatsApp. We also build APIs so other systems can consume your data.
Websites and landing pages
Product site, portfolio, or campaign landing, measurable from day one. It is the only service with a list price: it starts at $5,000 MXN.
When to build and when not to
We would rather say this before charging you for discovery.
| Your situation | What we recommend |
|---|---|
| You need standard invoicing, accounting, or e-signature | Buy existing software. It is solved and cheaper. |
| Your process is the same as your competitors’ | Buy. There is no advantage in building the generic thing. |
| Your process is the reason clients pick you | Build. No generic tool will respect it. |
| You pay for three licenses and still export to Excel to join them | Build the layer that joins them, or automate the flow. |
| You need to validate an idea with real users | Build a narrow MVP, not the full platform. |
If your case falls in the first column, we tell you on the call and suggest what to buy instead. We would rather lose a project than hand you something you did not need.
How we work
Build is the stage that moves: it stretches or shortens with the real complexity of the project. Discovery and launch stay about the same on most projects.
Discovery
Call, proposal, and design. We define what to build, in what priority, and in what order. This is where the full price and the delivery date get fixed.
Build
A demo every week. You see progress live and can change direction while doing so is still cheap.
Launch
Testing, training, and handover. Your team ends up running the system.
What you are left with
The repository and infrastructure in your name.
Documentation of how it works and how it is operated. Training for your team. Support and monitoring after launch. And the price we agreed at the start, with no extras appearing on the final invoice.
