You write a sentence. I build it.

No quotes and no hours to approve. You send what should happen in Slack, watch it get built, and move on to the next thing when it's done.

How it works

Four steps. No hours.

  1. 1

    Start the subscription

    One flat monthly price. No contract to negotiate.

  2. 2

    Send a request

    One sentence in Slack is enough. One active task at a time.

  3. 3

    We build, you watch

    You follow the work while it happens, not in a report afterwards.

  4. 4

    Shipped. Next!

    Done and live. Pause whenever you like, pick it up again whenever you like.

Step by step

What happens, in order.

  1. 1

    Start the subscription

    You pay by card, SEK 29,900 a month excl. VAT. Straight after paying you land in Ketryon's Slack, where all the work happens.

  2. 2

    Send a request

    Write what should happen, in one sentence or ten. You don't need a spec. If there's more on your list, we take it one thing at a time.

  3. 3

    We build, you watch

    Questions and work in progress arrive in Slack while it happens, not in a report afterwards. You can say straight away if something should change.

  4. 4

    Shipped. Next!

    When it's done and live, we take the next thing on your list. What's been delivered and paid for is yours.

Good to know

What holds throughout.

  • No lock-in

    No minimum term and no notice period.

  • Pause whenever

    The subscription ends when the paid period does. You can start again whenever it suits you.

  • One price, no hours

    The fee is fixed and paid in advance, one month at a time. Nothing to count or approve.

  • The code is yours

    Everything delivered and paid for is yours to keep and use, even after you cancel.

the next thing.

You talk to me, not a salesperson. The first call is free.
