You run the business. We run the system behind it.
We build a new website, shop or product, or take over the one you already have. Then we stay on as your technical team: we keep it running and tell you what’s worth building next.
You own the code, the data and every account·Our own products, live: XRay and Ampifex
First we learn how customers reach you.
We start with how customers reach you today, what staff answer on the phone and what they retype afterwards. Then we propose what would save that time, and build it.
If something breaks, we fix it and tell you.
A change that fails the automated tests doesn’t go live. Background tasks that fail retry on their own. Security and software updates are routine work. Every week you get a report: what broke, what we did and how long it took.
Bring your list. We’ll bring ours.
Every month we put your requests next to what we found ourselves: where customers still phone instead of booking, where staff retype orders. Each item says what it brings the business and how many hours it takes, and we tell you when something isn’t worth building. No new work starts until you approve it.
Not brochure sites. Systems the business runs on.
Booking, pricing and orders, with the back office wired in. Each case shows what we built, how it is tested and what it doesn’t show. Systems we took over for other clients stay under NDA.
Auto service · car-service siteDrivers price the job and book a slot themselves.A quote before the visit, bookings straight into the team’s calendar, pages in three languages, and an API that lets an AI assistant book for a driver.Read the case 
Logistics · freight forwarderShippers get a freight price in seconds, with the load drawn on the trailer.Shippers can get a price without calling. The ones who get in touch already know it, and their request arrives as a ready spreadsheet. The office edits its own rates.Read the case 
E-commerce · auto-parts shopThe right part by VIN. Every order lands in the back office.The catalogue follows the order management system. Lockers, courier and a separate route for oversize parts. If the order system is down, orders wait in a queue instead of getting lost.Read the case
We look at your business from every side, then build on what we find.
Before we change anything, and again after each release:
- What holds your site back. Errors, speed, security, privacy, wrong business facts.
- Who gets recommended instead of you. What Google and AI assistants answer when your customers ask.
- What your competitors do better. The same checks on the sites your customers pick instead.
You get a short list of what to build next, in order of what it brings the business. The checks run on our own two products, both live and sold on their own.

XRayWebsite · website audit
Finds what holds a website back, with proof.
It checks a site the way Google, AI assistants and a visitor see it: search, speed, security, privacy, accessibility and the business facts. Each problem comes with evidence and the fix.
We run it on client sites before we start, after each release and against their competitors. Your free first look is one of these runs.

Ampifex · content for Google and AI answers
Writes the articles that get a business recommended.
It learns the business’s voice, drafts articles on a schedule and in several languages, and publishes them on the business’s own site, built so Google and AI assistants can read and cite them. Nothing goes live until a person approves it.
We use it on client sites that need new content every week.

Who this is forSound familiar?
-
You need a system built, and someone to look after it after launch.
We build it and stay on as the team that runs it. What we build
-
Your agency or developer is gone, or the system is too old to touch.
We take over the code, accounts and hosting, and tell you in writing what to keep, fix or rebuild. How a takeover works
-
It works, but nothing new ships.
We sort your waiting requests by what each brings the business, add what we found ourselves, and you approve the order. A report every week. How ongoing work runs
-
Your tools don’t talk to each other.
Bookings in one tool, invoices in another, customers in a spreadsheet. We connect them into one system. How we connect tools
What we do
What we work withNew builds: TypeScript, Astro, Next.js and React, on Cloudflare or Supabase, with automated tests in Vitest and Playwright. Systems we take over stay on what they run on until the plan says otherwise.

Built to be run and extended, not rewritten.
Support and maintenanceThe same team, week after week
Fixes, updates and new features from the people who built or took over your system.

One team, one hourly rate, and a report of every hour.
Tell us about your business.
Write to us and we reply within one business day, Tallinn time (EET), usually within a few hours, and set up an online call.
A free call, and a free first look.
We ask how your business runs, what the system has to do and what’s getting in the way. If you already have a site, we also check it from outside with XRay, our own audit tool, and send a short written summary. Want us to go deeper? After the call we can scope a full audit of the code and servers. Ask about a full audit
One team, one rate.
Project manager, business analyst, architect, web developers, integrations, QA and test automation, security and DevOps. One hourly rate, whoever does the work.
You see every hour.
You approve the scope before we start. Weekly reports show what was done, by which role and how long it took, against the scope you approved. You don't need to be technical: the scope and the reports are written in plain words. See an example report
