How do I start an AI agency from scratch?
By the Fullday team · Published
Start an AI agency by picking one kind of local business, packaging an offer its owners already want (calls answered, leads followed up, a website that books), and running it on one platform under your own brand. Then build a working demo for a real business in that trade, show it to owners, and get your first client live within two days.
What does an AI agency actually sell?
An AI agency sells outcomes a local owner can feel: every call answered, every lead followed up, a website that books, reviews coming in and ads that bring in customers. The owner doesn't want to learn the tools. They want the phone answered and the calendar full, and they pay you monthly to make that happen.
What are the steps to start one?
You can do every step below in about a week without writing code. Do them in order, and don't move on until the step before is done.
- Pick one trade where a single customer is worth a lot, like dental, med spas, roofing or HVAC.
- Write a one-page offer: what you set up, how fast it goes live, and three monthly packages.
- Set up your agency on one platform with your own name, logo, colors and domain.
- Build a demo for a real business: their website rebuilt and an AI answering their phone in their name.
- Find a hundred businesses in that trade, score them, and reach out by email and phone with their demo.
- Run short calls: their numbers, their demo, the price, and a start date this week.
- Get each new client live within two days, then send a short report every month.
Which niche should I pick first?
Pick a trade where one new customer pays for months of your service, where owners are busy with their hands and miss calls, and where they already spend money on marketing. Dental implants, med spas, roofing, HVAC, plumbing and law firms fit. Pick one, learn its language and its busy seasons, and add a second trade only after the first one works.
How do I run an AI agency on Fullday?
Fullday gives an agency everything in one place: an AI front desk for calls and texts, websites that book, follow-up, reviews, ads and the search agent for each client, all under your brand. You find businesses with the lead finder, email them from your own inboxes, and connect Claude or ChatGPT so your AI can read your pipeline and work it with you.

- Claude and ChatGPT connection. Connect Claude, ChatGPT or Cursor, and your AI reads your clients, prospects and replies and works the pipeline with you.

How long does it take to start an AI agency?
Setting up takes a few days: niche, offer, your branded agency and a first demo. Landing the first client depends on how much outreach you do and how good your demos are, so plan for steady daily calls and emails.
How much does it cost to start an AI agency?
The main cost is your platform. On Fullday, agency plans start at $149 a month with one client included. You also need a business email and a phone, and you can add tools later as clients pay for them.
Do I need clients before I start?
No. Start with a demo for a real business in your trade and use it in your outreach. Owners respond to seeing their own business answered by AI far more than to a pitch about AI in general.
