An engineering team that has already been on the other side.

Ninety seconds: who we are, how we work and what you get at the end.

From your company’s documents to a system that answers and acts

Contracts, price lists, email, the CRM: what you already have becomes sourced answers and agents that do the work. Pick a case and follow the path.

Example: a customer asks what their policy covers. The system answers with the exact page of the contract and opens the case.

What we do for your company

Three things, always with fixed scope, price and date. All of them come out of your documents and your systems, and all of them are measured before they ship.

Does it cover theft from a car park? Yes, with a 10 % excess. Clause 4.3

01

Assistants that answer with a source

For your customers or for your team. Over your PDFs, email and databases. It answers with the citation; when it does not know, it says so and hands over to a person.

  • Customer support that resolves
  • Internal questions about policies and contracts
  • Search across thousands of documents

Agents that do the work

They query your systems, decide and execute: collections, quotes, reconciliation, follow-up. They ask for approval when the action has consequences, and they log every step.

  • Quotes with the right price
  • Invoice and purchase-order reconciliation

We connect the systems that do not talk to each other, build the software or app that is missing, and fix the AI you already bought that answers badly.

Fourteen sectors, and in each one the measurement changes

Insurance

Policy wordings, exclusions, claims

Says what a policy covers, quoting the clause and the version in force that day. If the wording changed in March, it answers with March’s.

AI for Insurance

An example

— Am I covered if my car is stolen from a public car park?

Yes, with a 10% deductible. 2026 policy wording, clause 4.3.

This is where the data comes in

An AI system is worth what its sources are worth. These are the standard connectors; anything with an API or a database connects the same way, and what has no API is handled by file.

Contact us
01

A 15-minute call, free

You tell us what you want to build or what stopped working. If it does not make sense to do it with AI, we say so on that call. Booked online, with no back-and-forth.

02

Proposal within 48 hours

Fixed scope, price and date. If scope changes later it is quoted separately and approved first — it never shows up as a surprise on the invoice.

03

Weekly working increments

You see something running from week one. No disappearing for a month and returning with a surprise.

04

Handover, documentation and a month of support

The code, the documentation and the evaluation set are yours, so your team can maintain and verify the system without depending on us.

A RAG system in production: three years, two million users

We built and operated the assistant for a loyalty platform serving more than two million active users across ten countries.

We built the full pipeline: document ingestion and normalization, chunking, embedding generation, vector store on Azure AI Search and Pinecone, and retrieval with grounded generation on LangChain.

We held it above 99% availability for three years.

What people ask before the call

Eight short answers. If yours is not here, that is what the fifteen-minute call is for.

01 How is this different from an agency charging a monthly subscription?

They sell access to a tool; we hand over a system that is yours, with its code and documentation. Subscription platforms work well for a simple FAQ bot — if that is what you need, hire them, they are cheaper. The difference appears when your information is large, changes often, or when a wrong answer costs you a customer: that is when you need to measure answer quality, and that is engineering, not configuration.

02 How is an AI project quoted?

With fixed scope, fixed price and fixed date, in a proposal that arrives 48 hours after the first call. Price is driven by three things: the volume of information, how many systems have to be integrated, and how much precision the case demands. If scope changes mid-project it is quoted separately and approved first — it never shows up as a surprise on the invoice. The diagnostic call is free and the range comes out of it.

03 Do you work with companies outside Colombia?

Yes. We are in Medellín (UTC−5), with full overlap with US Eastern and Central hours and all of Latin America. Most of our work in recent years has been remote with teams in Mexico, the United States and Colombia.

04 Is our data used to train models?

No. We use enterprise plans where data sent through the API is not used for training. When the case requires it we deploy on Azure OpenAI or Amazon Bedrock inside your own subscription, so information never leaves your infrastructure, and we filter personal data before anything reaches the model.

05 What if we already built something and it does not work?

That is the most common case that reaches us. Start with a diagnostic rather than a rebuild: the language model is almost never the problem — how the information was prepared and retrieved is, and that part can be rebuilt without throwing away the rest. In a week you know whether it can be rescued or should be rebuilt, with numbers behind the recommendation.

06 Do you work with agencies and product teams?

Yes, in two formats: fixed-scope projects with a defined deliverable, or a retainer embedded in your team, your process and your repository. For agencies we work white-label and only speak to your client if you want us to.

07 How long until we see something working?

An automation, two to three weeks. An assistant over your information, three to six. A system integrated with your business systems, six to eight. In every case you see something running from the first week, not at the end.

08 What happens when the project ends?

Everything is yours: code, documentation, infrastructure and the evaluation set so you can verify quality without us. We include a month of support to adjust whatever real usage surfaces, and after that maintenance is optional and quoted separately.

Fifteen minutes. A concrete answer.

It gets fixed, it gets built, or it is not worth it. And if the diagnostic does not reach three actionable findings, it is not charged.

No borrowed logos and no testimonials written by us.
