Working together

Who do you work with?

Startups, growing companies and their product teams, from pre-seed founders to established companies building something new. Individuals can also book our consulting sessions.

Where are you based?

In Čačak, Serbia. We work remotely with clients worldwide, in English, on Central European Time.

How does a project start?

With a free 30-minute intro call. If we are a good fit, you get a written proposal with scope, timeline and price. Work starts once you accept it and pay the first milestone.

Will you sign an NDA?

Yes. Send it before the intro call and we will sign it before you share anything sensitive.

Who owns what you build?

You do, once it is paid for: code, designs and documents made for you are transferred to you in full. Accounts and repositories are set up in your name from day one.

Do you make videos?

Yes: product and explainer videos, short-form content for TikTok, Reels and Shorts, AI-generated video, and pipelines that produce video at volume. Video projects are quoted in writing like any other project.

Can you work alongside our existing team?

Yes. Much of our work is with in-house or outsourced teams: setting up delivery, leading it for a period, or adding AI to what they already run.

Prices and payment

How much does a project cost?

It depends on the scope, so every project gets a fixed written quote after the intro call. Nothing is charged before you accept it.

What do sessions cost?

The strategy call is £350 / €400. All session prices are on the consulting page, and the intro call is free.

Which currencies do you accept?

Pounds sterling (GBP) and euros (EUR). Your confirmation or invoice states which one applies.

How do I pay?

By Visa or Mastercard, through a secure payment link. Card payments are processed securely, and we never see your full card details.

Do you charge VAT?

No. We are not registered for VAT, so no VAT is added to our prices.

What will I see on my card statement?

LUMTHERA.

Changes and refunds

Can I get a refund?

Payments are non-refundable, except where we cancel or cannot deliver, where a service is not delivered as agreed and we cannot put it right, or where the law gives you a right to cancel.

Can I reschedule a session?

Yes, once, free of charge, with at least 48 hours’ notice before the start time.

What if you need to cancel?

You choose between a new time and a full refund.

I am buying as an individual. What are my rights?

You can cancel within 14 days of the contract. If you ask us to deliver within that period, you lose that right once the service has been fully delivered. The terms of service explain the details.

Data and AI

What happens to the information we share?

It stays confidential and is used only to deliver your service. Our privacy policy explains what we keep and for how long.

Which AI models and tools do you use?

It depends on the problem, the data and your constraints. We choose the providers with you, with data protection and running costs on the table from the start.
