Which product do I need?

If something needs creating, rebuilding or rescuing, start with Kyln Build. If a live system needs monitoring and maintenance, choose Kyln Care. If the technical decisions need a senior owner, choose Fractional CTO.

What does Kyln Build cost?

Websites from £1,950. Products and platforms typically £15,000 to £35,000. A focused Review starts from £1,500 when the existing code or scope needs inspecting before a fixed build can be quoted.

What does Kyln Care cost?

Websites from £175 per month. Applications from £750 per application per month. Infrastructure from £500 per environment per month. Kyln audits inherited systems and recommends one scope rather than asking you to choose a tier.

What does Fractional CTO cost?

£5,000 a month for roughly one day a week. Three-month minimum. Advisor at £2,500 and Embedded at £9,000 are capacity adjustments used only when the role is clearly smaller or larger.

Do I own what Kyln builds?

Yes. You own the code, data, site and domain. Kyln Care and Fractional CTO can continue after launch, but neither is required to retain ownership.

The work behind the screen

Looking finished
is the start.

AI can get a prototype on screen quickly. Before customers depend on it, someone needs to check what happens when a payment fails, a user sees the wrong data or a release goes wrong.

From prototype to production

Before the first customer

The right access

Each customer sees only their own information.

A complete transaction

Failed payments and retries have a tested path.

A way back

Backups and recovery are checked before they are needed.

Spectinga / Getting revenue moving again

The cause found
in under 30 minutes.

A change of email provider sent marketing emails to junk. We traced the problem to DNS and sender reputation, and the click rate returned within the week.

“An unexpected tech problem dropped our revenue by 30%. This one issue was costing us tens of thousands of pounds a month, and Josh and the team at Kyln laid out the path to the solution in less than 30 minutes.”
