Retrieval assistants
Chatbots grounded in your documents or your public site. The work is in chunking, ranking and refusal — knowing when to say "not in my sources" instead of inventing an answer.

Tech Virsa ships its own AI-intelligent ERP platform, and we build agents, retrieval assistants and computer vision for other people’s products. Bring a new build, an existing codebase, or a process that needs automating. You work with the engineers doing the work.
A real grounded assistant: it retrieves from this site’s content and refuses anything it cannot source. Yours would answer from your documents.
Teams we have built for
Finds buyers on 9 platforms, gets the decision maker's email, scores every lead and writes the pitch and follow-ups for you. Set up for software and AI agencies, recruiting and staffing firms, and marketing and ad agencies. It runs every weekday and sends you the hot leads on WhatsApp.

We built and ship a complete SaaS ERP with an automation layer on top of it. Traditional ERP waits for someone to type. Ours watches the same data and acts — raising the order, flagging the anomaly, routing the approval — and asks a human only where judgment is actually needed.
A full multi-tenant system your whole operation runs on, not a bolt-on.
What the system handles on its own, with an audit trail on every action.
Every automated action is logged, reversible and attributable. An ERP that acts on its own is only safe if you can see exactly what it did and why — so that is built in, not added later.
Four things we build repeatedly, with the parts that decide whether they survive contact with real users.
Chatbots grounded in your documents or your public site. The work is in chunking, ranking and refusal — knowing when to say "not in my sources" instead of inventing an answer.
Systems that take an action, not just answer. Tool calls, approvals and a human checkpoint wherever an error would be expensive to undo.
Recognition and inspection on real images, not clean datasets. We measure accuracy before and after, because that number is the whole deliverable.
A test set before launch and dashboards after it. Without this an AI feature quietly degrades and nobody notices until a customer does.
We will also tell you when a problem does not need AI. A rules engine that always works beats a model that usually does — and it costs you less to run.
New products and existing systems. Client names are withheld where the engagement is covered by an NDA — the numbers are the ones we still stand behind.
40% → 80%recognition rateComputer-vision module rebuild
A property-tech product identified scanned keys only 40% of the time. We rebuilt the computer-vision module and recognition rose to about 80%.

A European household product needed a kitchen tablet plus companion iOS and Android apps, kept in production. The duration is evidence of retention, not a financial return.

Livebuilt + maintainedOngoing platform build + maintenance
A chatbot that answers from the open web, from a company's documents, or both — and stays grounded either way. We built those modes and still maintain the platform.
Ask about this engagement →Which one fits depends on how much is already known. We will tell you which you are in before you commit.
When the work is well understood
Websites, apps and ERP builds where the requirements are clear. You get a fixed quote after scoping and the price does not move unless the scope does.
When the outcome is still uncertain
A bounded first step for AI work nobody can price honestly yet. We find out whether it works on your data before you fund a full build.
When you need capacity in your team
Our engineers work inside your team and your process. We agree rate, capacity, responsibilities and a review cadence before anyone starts.
Every engagement is staffed by specialists who have shipped this exact kind of system before.

Growth strategy, content and paid campaigns run by a dedicated manager.
Send a few lines about the work. A senior engineer reviews whether we can do it and replies, usually within one business day. You get the approach and price in writing before anything starts. That is a fit review, not a free architecture specification.
Clear work can have a fixed quote after scoping. Uncertain AI work often starts with a scoped discovery or prototype, so nobody is guessing at a price.
The people writing the code own the reviews. You see progress in the repository and in the check-ins we agreed, not a separate weekly performance.
Handover includes the code, how to run it, and the access you need. What we keep maintaining after launch is written into the quote. It is not assumed.
You talk to the people writing the code. Reviews sit with that same group, not a separate account team. Between 20 and 50 specialists, each with 10+ years of experience.
