Questions

Common questions

The things people ask most often — before the first conversation.

What is LIONEX AI First Agency?

A Ukrainian agency for website and online store development and technical SEO, at lionex.com.ua. The full name is LIONEX AI First Agency. Commercial development since 2015; the contractor is a registered sole proprietor, Vladyslav Chystiakov. We work remotely with clients in Ukraine and Europe.

Is LIONEX AI First Agency related to other companies called Lionex?

No. The name is used by several unrelated companies in different countries and industries, including cryptocurrency exchange services. We have no connection to them: our only website is lionex.com.ua, and the contractor is a sole proprietor registered in Ukraine.

Who does the work?

Vladyslav Chystiakov. Your task goes straight into work — no account managers, no passing it through third parties. We reply within two hours. A project does not move to another contractor halfway through.

How much does development cost?

There is no public price list, and that is deliberate: the scope of nominally identical work differs several times over between clients, so a «from» figure would mislead. First a free review of the task within 1–3 business days, then an estimate broken down by stage, then a contract with a fixed amount. The base currency is the euro; hryvnia at the NBU rate on the invoice date.

How is the work formalised?

A written contract for every project: scope, deadlines, amount, acceptance procedure. The contractor is a registered sole proprietor; payment goes to a bank account with closing documents. A 30-calendar-day warranty from the date the acceptance act is signed. Property rights to the code, design and materials pass to the client after full payment. Domain, hosting, repository and analytics are registered in the client's name.

What we stand for

rules
04

We say "no" when we're not sure

If the task isn't ours or the deadline is unrealistic, we tell you upfront — not "we'll figure it out as we go".

You get access to everything

Hosting, domain, repository and analytics are registered to you. Want to leave — you take the project, no negotiations.

We don't promise rankings or ROI upfront

We promise speed, a deadline, and code that any other team can pick up.

We show work that actually works

Every case in the portfolio links to a live site you can open right now.

Process

How we work

stages
04
  1. Audit & brief

    Spec & quote

    We measure the current site: catalog size, speed, sitemap health, analytics.

  2. Structure & design

    Approved mockups

    Category tree, filter facets, mockups for home, category, product and checkout.

  3. Build & launch

    A working site

    Markup, catalog, payments and shipping, integrations, analytics, an end-to-end order run.

  4. Growth

    A report with numbers

    Post-launch measurements, data-driven fixes, ads. By priority — not "everything at once".
