Speed is money

Every second costs customers

Drag the slider: this is how much more likely a visitor is to close the page while it loads. That's why we build speed into the architecture instead of "fixing it later".

Message on Telegram
How much does a website cost?

A business website or landing page starts at $2,000, an online store at $3,500, a web app or CRM at $5,000–6,000, a mobile app at $7,000. We give a fixed price after a free brief — usually within 24 hours.

How long does development take?

A website takes 3–5 weeks, an online store 5–8 weeks, a web app or CRM from 2 months. Timelines are fixed in the contract and we demo progress every week.

Do you redesign existing websites?

Yes. We run a UX audit, find where the site loses customers, and rebuild design and code. Redirects are set up so you keep your Google rankings.

Is SEO included?

Technical SEO is part of every project: speed, semantic markup, meta tags, structured data, sitemap, hreflang. Ongoing promotion — keywords, content, links, Google Maps — is a separate package from $2,000.

How does payment work?

In stages: 40% upfront, 40% after design and development approval, 20% after launch. We work under a formal contract.

Do you work with clients outside Ukraine?

Yes. We work with businesses across Ukraine and Europe. We work fully remotely: briefs and demos over video calls, day-to-day communication on Telegram, in English or Ukrainian.

What happens after launch?

12 months of code warranty, team training, and then — if you want — support, SEO promotion and new features on an hourly or retainer basis.
