Rebuilding the pre-AI web, one subscription at a time
Most of the web was written for a search engine that no longer works the way it used to. SOSEI takes an outdated website and rebuilds it — modern, fast, AI-discoverable, GDPR-ready — then keeps it current for as long as the customer stays. The product is live and paying customers are on it.
Why now
Discovery moved to assistants faster than any platform shift since mobile — and the websites underneath it didn't move at all.
Search behaviour shifted in 18 months. People ask an assistant before they open a results page.
Answers are assembled above the links. A site that AI can't read is a site that stops being cited.
WordPress, Wix and hand-built static HTML, written for a search engine that no longer works that way.
What's already shipped
Not a prototype and not a waitlist — a production platform that scrapes, rebuilds, hosts and maintains real customer sites today.
sosei.site is shipped and serving paying customers across multiple industries.
Design and copy are grounded in a per-industry catalog — from legal to e-commerce — not generic AI output.
An outdated URL in, a modern multi-page AI-ready site out — hosted, on the customer's own domain.
Subscription, on our own hosting
No one-time builds and no WordPress export. The site lives on our platform, which is what makes the ongoing relationship real rather than contractual.
The upgrade treadmill is the product
Algorithms, AI crawlers and regulation keep moving. We move the customer's site with them — replacing the costly redesign every 18 months.
AI chat editor, guardrails in code
Owners edit by chatting. Accessibility, contrast, consent and legal pages are enforced by the pipeline, so a customer cannot break compliance by editing.
Built lean, by design
A small core team plus AI tooling ships the whole product. Capital goes to growth rather than to an engineering headcount.
The market
Every one of those legacy sites is a rebuild waiting to happen — and a rebuild is the start of a subscription, not the end of a project.
Estonia
A 45,000-website home market, targeting 10% over two years — small enough to win outright, real enough to prove the motion.
EU expansion
International from month seven. The product is English-first and language-aware by construction, so a new market is distribution work, not a rebuild.
Global & partners
Agency partnerships and white-label hosting — the segments that turn one relationship into a portfolio of sites.

The team
A lean core that has spent years on the web, SEO and AI — with experience from Wise, Pipedrive, LHV, Inbank, Eesti Energia, Change, Fleep, Western Union and Paxful.
A country of 1.4 million people that has produced Skype, Wise, Bolt and Pipedrive — more unicorns per capita than anywhere else in Europe. It's a small market that forces you to build for the world from day one, and our team has worked inside two of those companies.
Finance, marketing, design and security are covered by a CFO and named partners — the Team slide in the deck has the full picture, including the five-year hiring plan. More about SOSEI.
Let's talk
We're raising to accelerate the AI editor, launch e-commerce support and push international growth. If that's a thesis you recognise, we'd like to hear from you.
