AI training and consulting for small businesses

Learn to run your business with AI.
Then never need us again.

We don't sell software and we don't do the work for you. In one 3-hour session we find your biggest bottleneck, build the AI workflow that fixes it with you, and teach your team to run it on their own.

One session. £1,500. Yours to keep.

You know AI could help. Nobody shows you how to do it yourself.

Leads wait too long

New inquiries sit in the inbox while you're on a job. By the time you reply, they've booked someone else.

Admin eats your evenings

Quotes, invoices, scheduling and copy-paste between tools take hours every week that nobody pays for.

Agencies keep you dependent

You pay every month for software or an agency. The day you stop paying, everything stops, and you never learned how it works.

/ Our promise

Consult with us once. Then don't come back.

Most consultants want a retainer. We want you independent. You leave with the workflow, the playbook and the skills, and you never need to call us again.

Nothing to sell you

No software, no subscription, no retainer. You pay for one session and that's it.

Nothing done behind your back

We don't implement for you. You build it with us, so you know exactly how it works and how to change it.

Skills that stay

Your team leaves able to find the next bottleneck and build the next workflow on their own.

/ How it works

From bottleneck to working AI workflow in one session

One clear path. You always know what happens next and what it costs.

  1. 1

    Your business

    Leads, emails, quotes, bookings: the work your team does every day.

  2. 2

    Find the bottleneck

    Before the session we review how you work and pick the one thing slowing you down most.

  3. 3

    Design the workflow

    We map the AI workflow that removes it, using tools you already have or cheap ones you own.

  4. 4

    Build it together

    A 3-hour live session. Your team builds it with us, step by step.

  5. 5

    You run it

    You leave with a working workflow, a written playbook and the skills to build the next one.

/ What we help with

Two things AI can do for your business

Every session focuses on one of them. We have done both for our own businesses.

Build

Build with AI

Make the tools your business needs without hiring a developer.

  • Internal tools and dashboards
  • Automations between the apps you already use
  • Websites, booking pages and customer portals

We built Welkodia, software used by short-term rental hosts, as a two-person team.

Distribute

Distribute with AI

Get your offer in front of more customers, for less time and money.

  • Search pages and directories that bring in leads
  • AI that spots people asking for your service online
  • Outreach and follow-up that sounds like you

We built Jenexo, a junk removal directory serving the US, Canada and the UK.

/ The team

Built by operators, not by marketers

We run our own software and directory businesses with AI every day. We teach what we use.
