No call needed

Fixed estimate in 24 hours

Describe the task in two sentences. You get a fixed price, a timeline and a plan. If it isn't a fit for us, we say so straight away and point you elsewhere.

  1. 01We read the task and ask two or three questions if anything is unclear
  2. 02We put together the estimate: scope, price, launch date
  3. 03It lands in your inbox within a day. The next move is yours

No newsletters, no unsolicited calls. The answer comes by email.

Straight talk

Whether we are a fit.

So neither of us burns an hour on a call that was never going anywhere.

We take it on if

  • There is a real task and a deadline: launch, redesign, automation, an app.
  • Budget starts at €900 and you make the call, not a committee of five departments.
  • You want one team accountable for the whole result, from design to deploy.
  • Being found on Google and in AI search matters, not just looking nice.

We pass if

  • You are shopping for the cheapest quote. We won't do it for €150, and saying so beats failing later.
  • You need a full-time in-house developer. We work project by project.
  • The brief is "do something so sales happen" and there is no product or offer yet.
  • Every small change needs a week of approvals. Speed is half the value here.

Sounds like your situation?

Send a couple of lines about the task. We reply within hours and tell you straight whether we're the right fit.

Launched our store in 11 days — multilingual, fast, and already on page one for three of our main keywords.
Anna Kovalenko
The Telegram bot handles the first conversation with every lead now. My sales rep only steps in when the deal is hot.
Dmytro Orlov
Leads land in our CRM with every field already filled. No more copy-pasting from chats — the pipeline moves itself.
Katarzyna Nowak
Shipped to the App Store and Google Play in three weeks. The handover docs let my team take it from there without me.
Tomasz Lewandowski
Set up our Google and Meta ads from zero. Cost per lead dropped by about a third in the first month.
Oleh Hrytsenko
He rebuilt the site and six weeks later ChatGPT was recommending us by name. Didn't know that was even possible.

Frequently asked

Answers, before you ask.

  • A marketing site typically goes from kickoff to live in 2 to 3 weeks. Larger sites with custom integrations or multilingual content can take 4 to 6 weeks. Either way, you get a fixed launch date in writing before the project starts.

  • Yes. We work with Polish clients regularly: conversational Polish, fluent English, native Russian and Ukrainian. Contracts can be signed under Polish law and invoicing is handled with VAT EU.

  • Yes. Several of our projects ship in PL / EN / UA / RU simultaneously. We handle proper i18n routing, hreflang, locale-specific SEO and translation review with native speakers.

  • You get 30 days of bug-fix support included. After that, edits are billed at €50 per hour with a one-hour minimum. There is no forced monthly retainer — you only pay when you actually need work done.

  • AI agents start at €1,500 for a focused use case (a FAQ assistant, a lead qualifier, a single-tool automation). A sales agent with CRM is from €2,500; a multi-tool agent with integrations runs €4,500–12,000. Final price after a 30-minute scoping call.

  • Yes - cross-platform from a single codebase using React Native and Expo, then submitted to both the App Store and Google Play. If a project genuinely needs platform-native code, we say so upfront and quote it separately.

  • You message the developer directly. No account managers, no junior developers handling your project while a senior signs off. The person you brief is the person writing the code. Decisions take minutes, not weeks.

  • Yes — that's the default, not an upsell. Every site I build ships with technical SEO, schema markup, hreflang for multilingual pages, optimized Core Web Vitals and IndexNow pings on deploy. Most pages index within hours and start ranking within weeks.

  • Always. Every project starts with a written agreement covering scope, payment schedule, IP transfer, deadlines and what happens if either side wants out. Contracts can be in English or Polish.

  • Edits are billed at €50 per hour, with a one-hour minimum. No forced monthly retainer. You can come back six months later with a small change and we'll handle it - same terms, same rate.

  • Everything runs remotely, with clients across the EU, the UK, the US and beyond. Calls, demos and handover happen online; the contract and payment are remote too. Time zones are not an issue: I sync to your working hours.
