Frequently asked questions

  • How much does a project cost?

    Fixed-price projects typically run from $4,500 for a focused scope up to $27,000+ for a full platform build. If you’d rather not commit to a fixed scope, our monthly subscriptions start at $2,800. The exact number depends on how many unique screens, integrations, and mechanics are involved — a 30-minute call is usually enough for us to give you a real range.

  • How long does a project take?

    A landing page or promo site is usually 2–3 weeks. A full product — casino platform, sportsbook, DeFi dashboard — runs 2–4 months from first wireframe to launch. We work in weekly increments, so you see progress every week rather than waiting for one big reveal at the end.

  • Do you work under NDA?

    Yes, and most of our iGaming and betting work is covered by one. We’re happy to sign yours before discovery, or send ours if you prefer. It’s also why parts of our portfolio stay private — if you want to see NDA-covered work relevant to your project, ask on the call.

  • Can you work alongside our existing developers?

    That’s one of our most common setups. Plenty of clients have a solid backend team but no design competence in-house — we come in design-led, hand off production-ready specs, and take on frontend if your team is stretched. We can also plug into a single workstream inside a bigger product rather than owning the whole thing.

  • Do you only design, or do you build too?

    Both. Design is where most projects start, and full-stack development — React, Next.js, Node — is available when you need the build, not just the file. Some clients take design only, some take the whole thing end to end. Both are normal.

  • What’s the difference between a fixed-price project and a subscription?

    Fixed-price works when the scope is clear — you know what you need, we quote it, we build it. Subscriptions work when the work is ongoing or the scope keeps moving: you get a set number of active tasks at a time (1, 2, or 4 depending on the plan), and you can cancel any time. Most clients start fixed-price and move to a subscription after launch.

  • Which industries do you actually know?

    iGaming and betting are where we’re deepest — casino platforms, skin and case mechanics, sportsbooks, odds interfaces. Beyond that: esports, gaming brands, Web3 and DeFi, fintech, AI/ML products, and B2B SaaS. If your product lives in one of those, we’ve already solved most of the problems you’re about to hit.

  • How do we start?

    Book a discovery call — 30 minutes, free, straight with Sergey rather than a sales rep. Bring whatever you have: a brief, a Figma file, a competitor you like, or just the idea. You’ll leave the call with a realistic scope, a price range, and a timeline.
