Engagement/four models

How to work with us.

We are a small studio that ships across mobile, web, pipelines, games, and AI utilities. Here is how we package that into something you can buy.

Every engagement starts with a real brief, not a sales call. We answer four questions before we quote: what does success look like, what is the smallest version that ships, what is genuinely unknown, and what could kill the project. The answers go in writing before anyone signs anything.

Pricing below is honest range, not anchor. Small jobs land at the bottom of the range, multi-month builds at the top. Every quote includes a fixed price for fixed scope and a separate hourly rate for change-orders. We do not surprise you on the invoice.

Engagement models

  • Fixed-scope project

    from €4,000

    One app, one tool, one pipeline — defined scope, defined deliverable, single shipping milestone.

    Best for
    You know what you want and want it built. Mobile app, web tool, internal pipeline, or a polished case-study-grade build.
    Notes
    Small utility apps land at the bottom of the range. Multi-phase platforms like the poker-platform case study sit at €25,000 and up. We give a fixed quote after a paid two-day discovery.

  • Build-for-you (white-label)

    from €8,000 per app

    We build the app under your brand, ship it to your store accounts, hand over the source.

    Best for
    You have an audience or a niche but no engineering team. You want one of our shipped patterns (calculator app, tenant-rights companion, niche-utility Flutter app) re-skinned and re-targeted.
    Notes
    Includes one round of post-launch fixes within the first 30 days. Store accounts, signing keystores, and ad / IAP credentials are yours.

  • Retainer

    from €1,500/mo, up to €6,000/mo for a full-time-equivalent

    Ongoing build + maintain across one or more surfaces. Predictable monthly rhythm.

    Best for
    An app or stack that needs a steady stream of features, store-listing updates, and the occasional incident response. Not a fit for ad-hoc tickets or pure on-call.
    Notes
    Three-month minimum, 30 days notice to end. We publish a weekly summary and keep the project board public to you.

  • Advisory

    from €200/hr or €1,200/day

    Architecture review, second opinion on a build, async questions, or a few days of pair-programming.

    Best for
    An in-house team that wants outside eyes on a Flutter / Next.js / Python pipeline before they commit to a path, or a founder who needs a technical co-pilot for a single decision.
    Notes
    We do not take retainers disguised as advisory. If the work crosses ten hours, we convert to fixed-scope or retainer — whichever fits.

How a project runs

  1. 01

    Discovery

    Paid two-day deep dive. We read your existing code, talk to two or three of your users, and write a one-page brief that names the scope, the unknowns, and the ship date. Cost credits against the build if we move forward.

  2. 02

    Scoped quote

    Fixed price for fixed scope. We list every feature in the build and every feature explicitly out. Change-orders get their own line item, never folded into the original quote.

  3. 03

    Ship

    We work in week-long milestones with a Friday demo and a written changelog. You see every commit on a feature branch before it merges. The Studio Log on this site is real — every project gets the same treatment.

  4. 04

    Handover or ongoing

    Either we hand over a documented codebase with deploy scripts and a runbook, or we roll into a retainer. Both are fine. Either way the source, the store listings, and the credentials are yours.

What we won't take on

Saying no in advance saves us both a discovery call. We are not interested in any of the following, even at a premium.

  • Crypto trading bots, financial signal services, or anything that takes positions on behalf of a user.
  • Anything requiring us to hold customer funds, KYC users, or carry a money-transmitter license.
  • Pure agency-of-record retainers where we do not ship code.
  • Hourly time-and-materials with no scope cap. We quote scope, not stopwatches.
  • SEO content farms, AI-content-spam pipelines, or scraping operations whose target site asks us not to.
  • Enterprise sales decks. We are a build studio, not a slide studio.

Start

Tell us the shape of the problem in two paragraphs. Include the audience, the deadline if there is one, and any constraint that rules things out (platform, budget, regulator, integration). We reply within two business days with either a discovery proposal, a referral, or an honest no.
