Meet the founders.
A small firm on purpose. You work with the people who built the thing, not an account team. And the whole story started somewhere you would not expect.
Over a decade in investment management across LaSalle, Aviva and Weybourne, the Dyson family office. Has signed the IC memo. He sets the standard for the work, and he is the reason any of this exists.
Chartered accountant, ex-BDO, with finance leadership across mid-market and owner-managed businesses. He makes sure the work pays its way for your business, and that you own what we build.
From a haircut to a thesis.
Three moments. One idea that kept proving itself.
The barber's chair
A barber in a small Argentine town was already running his bookings on AI. Teddy was doing multimillion-pound property deals the old way. The gap was enormous.
Structuring the data
Back home he threw everything at it, every day, in public. The lesson underneath: point AI at messy data and it lies to you. So the work became structuring data first.
Tercero
Built once, owned by you, kept correct as the world moves. Proven in real estate, now in any business that wants AI to actually work.
It started in a barber's chair, 7,000 miles from London.
In March 2023, Teddy was in Argentina, visiting his fiancée's hometown in the hills of Córdoba. He went in for a haircut. Halfway through, the barber, Joaquin, mentioned almost in passing that he had just built his own booking app for the shop, run off a Google Calendar.
Teddy was impressed. "You can code?"
No. I used ChatGPT.
Joaquin, the barber
Teddy had only ever used it to write the odd silly poem. He walked out of that chair thinking about one thing, and he has not really stopped since.
If a barber in a small Argentine town was already running his business on this, and Teddy was doing multimillion-pound property deals in London the old way, the gap between those two worlds was enormous. And someone was going to close it.
So he did.
Back in London, he threw everything at it. Applying AI to real estate, every single day, on public data, testing what it could really do and posting what he learned on LinkedIn. People in property started paying attention. The name Teddy began to come up whenever someone asked the question everyone was suddenly asking: who actually understands this?
There was a harder lesson underneath the excitement. Point AI at a firm's messy data and it gives you a confident, wrong answer. Get the foundations right and everything changes.
So Tercero was built on a single idea: it starts with structuring your data.
Get that right, and AI can finally answer your own questions, run your reporting off your real numbers, and take the manual work off your team. Built once, owned by you, kept correct as the world moves. It worked. Across real estate, investment and institutional clients, the same approach kept proving itself, built by someone who has signed the IC memo, not a tech company guessing at what investors need.
Then the requests started coming from outside real estate.
Companies that felt left behind. Businesses without a big firm's budget, but wanting the same insight and the same efficiency. The principles travelled. So we built our SME arm: working with any business to become genuinely AI native, harnessing their data, building the automations, and freeing their people to do the work humans should be doing.
The world is moving fast, and the surest way to stay at the front is to partner with people who have been there from the start. That is what we are.
Become AI native.
Real estate investor or growing business, we get AI working properly in yours, built on your own data and owned by you.
No forms, no funnel. Your email lands with a founder.
