What we build

Six fronts, one supplier. We deliver the whole digital side of your operation so you don't have to stitch together six companies that never talk to each other.

  1. Front 01 / 06

    Websites thatbring in leads

    Not a static brochure. A page that loads fast on mobile data, shows up on Google when someone searches for what you sell, and walks the visitor to the WhatsApp button without wasting their time.

    What you get

    • 01A page that loads in under a second
    • 02Built for the phone, where your customer arrives
    • 03Copy that explains the business in five seconds
    • 04WhatsApp button with the message already written
    • 05Domain, hosting and certificate live

    Softwaremade to measure

    The software your operation needs and nobody sells off the shelf. It replaces the giant spreadsheet only one person knows how to use and the three tools that never talk to each other.

    • 02Access by role: everyone sees what is theirs
    • 03Reports that come out ready, no manual merging

    AI agentson WhatsApp

    A digital rep that answers on the spot, understands a message however it is typed, qualifies the lead and books the appointment. At 11:47pm on a Sunday too.

    What you get

    • 01Answers in seconds, 24 hours a day
    • 02Trained only on your business information
    • 03When it doesn't know, it hands off to a human and says so

    Processautomation

    We connect the tools you already use so the repetitive task stops going through your hands. What is copy-from-here and paste-over-there today becomes something that happens on its own.

    What you get

    • 01Spreadsheet, CRM and email talking to each other
    • 02A record is entered once and lands everywhere
    • 03Automatic alert when something gets stuck
    • 04Reports arriving at the agreed time

    A website nobody finds is an expense. We fix the technical side, write the content that answers what your customer actually types, and look after the profile that shows up on the map.

    • 02Content that answers your customer's search

About HAOA TECNOLOGIA

We build software for small and mid-sized companies that already have an operation running and need the technology to keep up. A website that shows up on Google and makes WhatsApp ring, software that replaces the spreadsheet nobody can stand anymore, an AI agent that answers the customer at eleven at night.

We have delivered for manufacturing, a bar, a dental clinic and an insurance brokerage, and the bar is always the same: what we ship has to work without someone holding it up from behind.

Good software pays for itself: in customers answered, in hours saved, in deals closed.

Founded by Yudi Kashihara, a developer with 15 years of production code behind him, from financial markets to in-house AI products.

Here, the person who sells is the person who builds.

The questions everyone asks before signing

How much does it cost?

The price is fixed in the proposal, after the discovery call. Custom software has no price list: a single-page website and a system that replaces your whole operation do not cost the same. In the 30-minute call we size the problem and you get a fixed number, with the scope in writing.

How long does it take?

It depends on the scope. A website usually ships in weeks. Software is phased into weekly releases, so you are already using the first part while the second is being built. The deadline goes into the proposal alongside the price, before we start.

Do I need to understand technology?

No. You describe the problem in plain words, the way it happens in your day. We translate it into technology. If the explanation ever turns into acronym soup, that is on us, and we rewrite it.

Once it is delivered, who looks after it?

Support and maintenance are agreed in the proposal, with the scope and response time in writing. You are not left stranded with a live website nobody knows how to touch. Training your team is part of the delivery.

I already have a website. Can we reuse it?

We can assess that in the discovery call. Sometimes the problem is narrow and nothing needs rebuilding. Sometimes the foundation is old enough that patching it costs more than building again. We tell you which of the two is your case before you spend anything.

Won't the AI say something wrong to my customer?

The agent is trained only on your business information and works inside limits you define. When it doesn't know, it doesn't invent: it hands off to a human and says so. Every conversation is logged so you can check what was said.
