Short answer: Ishigai's prices start free. The website report costs nothing, the AI Opportunity Audit is from £750 and credited in full against a pilot started within 60 days, a 30-day pilot is from £2,500, and managed AI agents run £379 to £2,000 a month. Every build ends with a roadmap and handover at no extra cost.
The ladder, in order
| Step | What you get | Price | Credit |
|---|---|---|---|
| Free website report | Where your site loses enquiries and what to fix first. Two minutes, no account, no call. | Free | None needed |
| AI Opportunity AuditStart here | A ranked, costed map of where AI saves your firm hours, including the "don't bother" calls. One to two weeks. | From £750 | Credited in full against a pilot started within 60 days |
| 30-day Pilot | One workflow, one owner, measured before and after. Larger builds across several systems run up to £15,000. | From £2,500 | The £750 audit fee comes off it |
| Managed AI Agents | Agents that research, respond and follow up, monitored and tuned every month. | £379 to £2,000 a month | Build scope agreed before we start |
| Roadmap & Handover | Documentation, running costs and a roadmap your team or another provider can pick up. | Included | Never sold separately |
Not sure where to start? Start with the audit. It is the cheapest way to find the one place worth building, and if you go ahead with a pilot within 60 days, it costs you nothing extra.
For product teams
| Service | What you get | Price |
|---|---|---|

How the prices work
- Fixed before it starts. You get a written quote before any build. Nothing is billed by the hour.
- No obligation. The audit is standalone. You keep the roadmap whether or not you build anything with us.
- No lock-in. Every build is documented so your own team or another provider can run it.
- All prices in GBP. Monthly agent retainers are billed monthly.
Frequently asked questions
Why does Ishigai publish its prices?
Because most firms can't judge whether AI is worth it without a number. Every step is priced before it starts, so you can decide on the facts rather than after a sales call.
Where should I start?
With the AI Opportunity Audit, from £750. If you're not ready to spend anything, run the free website report first.
Is the audit fee refunded if I go ahead?
It's credited in full against a pilot started within 60 days, so the audit costs nothing extra if you build.
Why does the copilot start at £8,500?
That buys a focused first version: one area of your product, up to five workflows and four weeks of work, with a confirm step before anything changes data. Bigger scopes depend on how much of your product it reads and how many actions it supports, so they get a fixed quote in writing after a short technical discovery, before any work starts.
