  • Within 24 business hours we answer your message, with next steps.
  • Spanish or English remotely, with meetings that fit your time zone.
  • Talk to the person building it

    Questions, decisions and progress don't get lost between intermediaries.

  • Your budget goes into building

    With no sales staff or middlemen to support, it goes to what you need.

  • What matters comes first

    Together we decide what to solve now and what can wait.

What we do for your business.

Look for what sounds most like your situation today.

Your information lives in spreadsheets.

ERP implementation. We get your ERP live, the system that brings sales, inventory and accounting together, and connect it to everything else so your data stops living in spreadsheets.

Tell us your situation

No off-the-shelf program fits how you work.

Websites and platforms. Landing pages, websites, platforms and mobile apps built around your business, from the first sketch to your team using them every day.

Tell us your situation

Your team repeats the same work all day.

AI automation. Agents, chatbots and automatic document reading that take over the repetitive work and free up your team.

Tell us your situation

Your tools don't talk to each other.

Integrations. Payments, invoicing, messaging and whatever you already use, connected so nobody types the same thing twice.

Tell us your situation

You find out how the business is doing at month's end.

Dashboards and analytics. Real-time dashboards that turn your data into decisions, with the metrics that actually move the business.

Tell us your situation

What you sell is hard to explain with a photo.

3D and simulation. Simple low-poly 3D models and simulations that show how something looks or works. Made to explain, not for precision engineering.

Tell us your situation

What we've already delivered.

A real website you can visit today.

We've also built internal systems, AI and integrations for other businesses.

Tell us your situation and we'll say if it's similar.

Why one system.

Everyone has their own version, and someone loses the morning comparing them.

Today your business lives in pieces.

We bring it into one system.

Who's behind it.

One person, start to finish.

Tharsis is a small software studio in Peru. Your message is read by whoever designs, codes and delivers it: there's no salesperson promising what someone else will have to build.

Tharsis is also a place on Mars.

What you're probably wondering.

Tap a question.

How much will it cost me?

It depends on what you need, so there's no single rate. Talking to us and getting a proposal is free, and it shows you the investment before you decide.

How soon can I have it?

It depends on the scope. Dates go into the proposal and, while we build, you get to try the progress.

Can you give me an invoice?

Not for now. We're a young venture without a RUC, Peru's tax ID, so we don't issue invoices or receipts.

I know nothing about systems. Can I still do this?

Yes. Tell us your problem in your own words and we take care of the rest.

Do you only build invoicing systems?

No. We build websites and landing pages, platforms, apps, AI automation, dashboards and simple 3D. Invoicing is just one of the cases.

I already have a system. Do I have to throw it out?

Not always. If it can be reached from outside, we connect it to whatever you need. If it can't, we tell you and look at alternatives.

How do payments work?

By milestones or through an ongoing collaboration, depending on the project. Amounts and dates go into the proposal.

What do I get at the end?

What the proposal sets out: code, access, documentation and support. You'll know before we start.

You're one person. What if you're ever unavailable?

That's why each project's proposal sets out which code, access and documentation you receive, and when.
