Crown Ventures builds and runs web products for small businesses and the people they serve. AI coding agents write the code. Every product begins with a written specification, every change is reviewed, and nothing ships until the full test suite passes.
See the productsBoth suites must pass before any release of twelvedimensions.co, including one-line changes.
Each was specified, reviewed and released by one person directing AI agents.
Score your website out of 12. Free, in about sixty seconds.
12D reads a site's public pages and scores how clearly people and AI assistants can understand and trust the business behind it, across twelve brand dimensions. A Blueprint lists the exact changes to make; monthly plans re-score the site and track competitors.
A complete online presence, quoted at a fixed price.
The studio builds the brand behind a website as well as the site itself, then handles hosting, domain, analytics, Google listing and legal pages. It begins with a free 30-minute brand review. The client owns the code.
Support alongside your medicine.
Poornam matches people with vetted practitioners across twenty complementary-healing modalities. A 45-minute assessment on Zoom leads to a written plan, and every match is reviewed personally. It works alongside medical care, never in place of it.
An AI receptionist that answers every call.
Bellrook's voice receptionist answers calls, handles callers' questions, walks them through choosing an appointment slot and triages dental emergencies, sending urgent cases to NHS 111 or the clinic. Built first for UK dental practices, it adapts to clinics, yoga studios, spas and restaurants. Bellrook also builds workflow automations for accountancy firms.
Indian city guides for family trips.
One page per city: what to see, what a day realistically costs and where to stay, with a free trip plan shaped around your family.
Each gate is passed in order. An agent cannot skip one.
Inputs, outputs, edge cases and acceptance tests, written precisely enough that an agent cannot misread them.
The agent proposes how it will build the change. Work starts only once the plan is approved.
Every change is read against the specification before it is accepted.
The full unit and browser suites must pass. There are no exceptions.
For teams building software with AI agents, and for businesses that need AI at the front desk.
Find where AI-generated code is causing rework, then put in place the specification, review and test gates that stop it. Ends with a written playbook.
Specifications written for agents, orchestration design and release validation for teams shipping with AI.
A voice receptionist or workflow automation for clinics, studios, spas, restaurants and professional practices.
The agents are fast. Speed was never the hard part. The hard part is clear specifications, change control, tests, and someone accountable for what ships.
