Who we are · Liverpool, UK
A Liverpool startup, building this in the open.
Planaroo shows what any UK home could become: every room, the extension, the loft, the frontage, the garden, drawn onto the real house. We build it from Liverpool, on the Baltic Ventures Accelerator, alongside the homeowners, estate agents and local trades who use it.

companies chosen, building across AI, energy, health and property technology.
of them is Planaroo. Property technology, made in Liverpool.
From the Launchpad to the Accelerator.
Each step with Baltic Ventures has given us the room, the mentors and the local network to build Planaroo properly, rather than rushing something thin out of the door.

- 01
The Launchpad
We started on the Baltic Ventures Launchpad, testing the idea on real listings and real vendors around Merseyside. The best ideas in the product came from someone using it on a live property.
- 02
The Accelerator, 2026 cohort
Chosen from 400 applications as one of eight companies on the 2026 programme. Weekly time with founders and operators who have built and sold companies, and a cohort that pushes us on.

The Angel Syndicate
Backed by the Baltic Ventures Angel Syndicate, who put our first investment in. Merseyside first, then the rest of the UK. The aim has never changed: help anyone looking at a property see what it could become.
How we work.
Three habits that decide what goes into the product and what stays out.
Show, do not tell
Potential is hard to picture in words. We draw it onto the actual house, so the opportunity is obvious in a glance.
Grounded in the real
Every picture starts from the property's own photos, its address and the planning history of its street. No generic advice.
Honest about the odds
We flag the constraints as clearly as the upside: conservation areas, head height, the checks that decide whether an idea is realistic.
The founders.
Two of us, both in Liverpool. Say hello.

Builds the engine: the planning data and the technology that turns a photo and an address into a full-colour picture of what a property could become, in minutes.

Try it on your own home, or on a listing you are trying to sell. It takes a photo and a few minutes.
