Pre-seed · 2026

Every small business gets an AI team.

Five AI teammates and a chief of staff, built into the one system that runs your website, bookings, customers and money.

Other AI platforms plug into the tools you already pay for — Google, HubSpot, Xero — and sit on top. Simma is the tools, so its AI team works on one record, not ten. Built first for studios and one-person service businesses.

Why now · who's starting

The next wave of small businesses is starting now.

As AI moves into large companies, more people will leave corporate roles and build a business around what they love: a studio, a skill, a craft. Simma is there on day one, with the website, bookings, payments and an AI team in one place, and no tools to choose, connect or migrate.

tools to switch from

A new business has no stack to migrate. It is the one moment an all-in-one platform doesn't have to win a switch.

The move away from corporate roles is our forecast (vision). The formation figures are published statistics.

The problem

The owner is the integration.

A studio runs on eight tools that don't agree with each other — so at 10pm the founder copies bookings into invoices and customers into mailing lists.

"AI operating systems" add a ninth layer on top, wired into Google, HubSpot and Xero. It connects to the eight. It doesn't replace them — so the owner is still in the middle.

The difference

Simma doesn't connect to the tools. Simma is the tools.

Email, CRM, chat, customers, products, bookings, invoices — and every public face of the business: website, support, phone numbers, email addresses. Owned, not connected — which is why its AI teammates can do real work.

An AI operating system

A layer, connected in

Every action crosses into another company's system — on their terms, for as long as they allow it.

Simma

One system, owned all the way down

No connectors to keep alive. The AI team acts on tools Simma built, on records the business owns.

Simma started as an all-in-one system, before the AI wave. The platform came first; the AI team is built on top of it.

That order is the point. AI teammates need one owned record to act on, and AI layers borrow theirs from Google, HubSpot and Xero. Draft is a feature. Finish is a platform.

Why owning the tools matters — the full argument →

The platform

Everything a service business runs on.

One login. One record. The tools themselves, built as one. Specialists go deep on one job; Simma covers the whole business, with the parts of each tool a small business actually uses.

Presence

A presence it owns

Website, email addresses and phone numbers — how search engines, AI answer engines and Google Maps find the business.

Money

Book and pay, end to end

The slot, the payment and the invoice file themselves against the same customer.

Back office

Where the team — and its AI teammates — work

Projects, rota, files, reports and settings, on the same record as the front door.

Your AI team

Five AI teammates and a chief of staff. The owner stays in charge.

Every account comes with them, on every plan including Free; how much they can do grows with the plan. They work inside the same tools, on the same records, behind the same approval gate as the humans.

One-person service businesses, where the founder's time is the whole company.

The model

Free to start. Priced to grow with the business.

The cheapest way to start: on Free there is no monthly bill until the business is paid. For a business taking its first few hundred pounds a month, that costs less than a website, booking tool, email tool and card processor bought separately. As it grows, it pays for the whole system: one record, the AI team, nothing to join up.

Why this exists

"I'm building the platform I always wanted."

Paul O'ConnorFounder, Simma · 20 years in product

I used to run small businesses. CRM in one place, email marketing in another, files in Dropbox, payroll in IRIS, a separate events tool — everything patched together, and half the team locked out of half of it to save on licences. So I started building the all-in-one platform, evenings and weekends, alongside my day job — and then AI arrived mid-build, and the vision grew: not just one place to run a business, but agents to help run it.

The platform is in production. No customers yet — and the honest reason is me: I still lead product at a FTSE 100 company by day, and I won't take on businesses I can't yet serve. Simma needs me full-time to win its first customers; its first customers are what get me full-time. That chicken-and-egg is what this raise is for. I go full-time from first close.

Not alone for long. The first hires are sales and customer success (month 2), an engineer (month 4) and a second sales and customer success hire (month 6). Beyond them, eight people I've worked with have agreed to join as the plan grows. Meet them →
