How a build with us compares with the other ways to get an agent.
| Question | Us | A no-code freelancer | A £25-a-month app | A big consultancy |
|---|---|---|---|---|
| Who builds it | Senior-led: an architect since 2007, building software since 2005, leads every build, with vetted engineers added as it grows. | A builder who works in no-code tools. | You, inside the app. | The team the firm assigns. |
| Fits how you work | Built into your tools and your rules, with code where it is needed. | As far as the no-code tool allows. | You work the way the app works. | Yes, at consultancy prices. |
| Price | From £4,500 for an agent, priced up front. | Varies by freelancer. | £25 a month. | Day rates, quoted after discovery. |
| Time to live | An agent in 10 working days. | Varies. | Quick to switch on. Then you set it up. | A discovery phase first. |
| After go-live | Agent Care, from £750 a month. | Depends on their next project. | The app's help desk. | A new contract. |
Hands-on. I build the agents myself.
Hash
Founder, architect and engineer
Hand-built by Hash. You deal with me, not a sales team.
Hash on LinkedInYou work with the architect who leads your build.
I'm Hash. I've built software since 2005, and worked as an architect and engineering lead since 2007. I've led teams, run AWS migrations at LexisNexis and Specsavers, and led the booking platform upgrade at Travelodge. On larger programmes I've built the delivery team too, hiring and leading the engineers for Travelodge's move from on-premise to AWS. Today I build AI agents every day, ship my own AI products, and teach other builders to do the same. You work with me directly, with no account managers and no hand-offs.

We're not tied to one AI. Claude plans and writes, Codex works through screens and long coding jobs in the background, and n8n runs the workflows. You get what works best for each job.
Companies we've delivered for
The booking platform behind millions of hotel stays, moved from in-house servers to AWS.Led the on-premise to AWS migration and the booking platform upgrade, and hired and led the delivery team.
Merchants take card payments on the shop platform they already use.Payment integrations across e-commerce platforms.
- Super Payments
Shoppers save on every order, and Super earns on every sale.Built bank-transfer payments that skip card fees. The saving goes to shoppers as a reward, and Super earns a commission. I also set up the greenfield projects with automated releases, so the team shipped often and got client feedback fast.
Insurance data processing modernised, so it grows with demand without buying more servers.Moved it to cloud-native AWS as part of a wider digital transformation.
Teams release faster and more safely, and one change no longer breaks everything.Split the monolith into microservices on AWS with automated releases, and brought in agile practices and process automation.
Questions
Anything else, ask on the call.
What do you build?
AI agents that run a job your team repeats every day, such as replying to enquiries, following up and publishing posts. Self-running departments made of several agents. Custom software such as dashboards, CRMs and internal tools. Claude Code and Codex rollouts for engineering teams. And for agencies, a senior architect who reviews and hardens client builds.
Who works on my project? What if the work grows?
You always work with me, and I stay your single point of contact. When a project needs more hands, I bring in engineers I've vetted myself, the same way I've built delivery teams for large AWS programmes. I review every piece of work before it reaches you, so quality doesn't drop as the team grows.
How fast can it be live?
The agent build sprint puts one agent live in 10 working days. A Claude Code and Codex rollout takes 30 days. We scope custom software on the call.
What does it cost?
An agent build sprint is from £4,500. A Claude Code and Codex rollout is from £9,000 per team. Agent Care is from £750 a month. For agencies, we price the work on a call.
What happens on the free call?
In 20 minutes we look at how work gets done in your business and find where AI fits. You leave with a clear first step, whether you buy or not.
