AI builds websites ten times faster, but nobody guarantees what comes out. Sprout does: new sites are compliant by default, and every site a company already owns sits in one panel, checked and fixed.
A web where every website is secure, discoverable, sustainable and accessible to everyone.
Put companies back in control of every website they own: see them all, fix what fails, and build new ones right from the start.
Websites have become regulated infrastructure (EAA since 2025, GDPR, NIS2 and carbon reporting), yet 96% fail accessibility checks, and AI is multiplying them faster than anyone can check. Most companies can’t say how many sites they own, let alone whether they comply.
We started invoicing in September 2026. Since then, agencies have signed on as partners and enterprise teams are testing Sprout on their own sites.

Every site is data, not code, compiled into static pages and checked before it can go live. Competitors can’t copy it without rebuilding their platforms from scratch.
Legacy CMS sites sit at 50–70
Industry average 0.36 g
Hosted on OVHcloud, carbon calculated per page
Every site is stored as structured data with fixed rules (sprout-admin).
No database, admin or runtime on the live site to attack (sprout-site).
Isolated, and exportable at any time (sprout-deployer).
WCAG 2.1 AA and RGAA enforced: only what passes gets published.
Scanners stop at the report. AI builders build fast but don’t check. Sprout is the only one that does both, on top of whatever built the site.

Carbon method: Sustainable Web Design Model, verified with Website Carbon, Eco Index and Ecograder.
Accessibility and low carbon aren’t add-ons we sell: they’re how every Sprout page is built and checked before it goes live.

| People with dyslexia or cognitive disabilities | Cluttered pages with no clear structure | Clear headings and structure, type sizes locked to the brand scale |

Every large company’s website is now regulated. Today they pay scanners to find problems and agencies to fix them. Sprout does both, on one platform.
All in scope of the EAA
Plus 20–30K web agencies
For a tool that only reports
Security, speed, sustainability, accessibility
| Step | Who | Size | How we get there |
|---|---|---|---|
| Today | First customers and agencies | €1,600 MRR | InfoAdex, Grupo Raíz, 2 agencies paying |
| Our pipeline | 1,800 agencies identified, at €199 a month | €4.3M a year | Partner programme and the free checker |
| Europe, monitoring | 53,000 large companies at ~€12K a year, plus 20–30K agencies at €199 a month | ~€700M a year | Monitoring needs no migration: the easy first sale |
| Europe, full platform | The same companies moving sites onto Sprout | A share of €20B | Fix with Sprout and the builder replace agency builds and maintenance hours |
| Large companies with many websites Hundreds of brand, market and campaign sites, no central control. Today: agencies for every build, plus scanners that only report. |
| Web agencies Clients now expect compliance; audits and fixes eat 10–20 developer hours a month per client. |
| In-house web teams Building with AI tools, fast, but nobody checks what ships. Sprout checks before release, fixes as pull requests and plugs into their AI tools through MCP. |

Fines, court orders, mass exploits and lost traffic: what happens to companies whose websites nobody is checking.
The flaws hit PHP 5.4 to 8.5. Around 79% of exposed servers run versions that will never be patched, and European government sites went offline after disclosure.
For Sprout: Sprout sites are compiled static pages: no PHP, no runtime, nothing to patch.
The Caen court gave Carrefour six months, with €500 a day after that. Carrefour argued it met 71% of the criteria; the court said partly accessible is not enough.
For Sprout: Sprout blocks publishing until a page passes, so compliance is 100% or it doesn’t go live.
When Google shows an AI Overview, clicks on the top result fall by up to 58%. Pages cited inside the answer get about 35% more clicks.
For Sprout: Sprout scores and fixes AI discoverability: structured data, clean markup, pages AI can read and cite.
The CNIL’s largest cookie fines: trackers set without consent, unclear banners and refusals that didn’t work.
For Sprout: Sprout checks cookie consent on every site, including the ones a company forgot it had.
Veracode tested more than 100 models on 80 coding tasks: 45% introduced OWASP Top 10 vulnerabilities, and cross-site scripting failed in 86% of cases.
For Sprout: Whoever builds the site, AI included, Sprout checks it before it goes live.
Spain’s Audiencia Nacional upheld the fine and a six-month ban on public aid. The site met 4 of 38 requirements, the same as when it was first sanctioned in 2016.
For Sprout: Spanish regulators already fine for this, and the EAA now covers far more companies.
Lighter websites aren’t only greener. They load faster, sell more, and are where the standards are heading.
Deloitte’s study for Google of 37 brands and 30 million mobile sessions: shaving a tenth of a second raised retail conversion 8.4% and spend 9.2%, and travel conversion 10.1%.
For Sprout: Lighter pages load faster. Sprout pages start at 25 KB and score 95–100 on Lighthouse.
The W3C’s Web Sustainability Guidelines are now in draft as a Group Note, the same body that writes WCAG for accessibility. Sustainability is on the path accessibility took.
For Sprout: Sprout already measures CO₂ per page and builds to these principles by default.
The ADEME–Arcep study: without action, digital’s footprint triples and its energy use doubles by 2050, before counting generative AI. 79% of it comes from users’ devices.
For Sprout: Lighter pages need less energy on every visitor’s device. That is where Sprout cuts 99%.
The RGESN, from Arcep and Arcom with ADEME, sets 78 criteria. Cities over 50,000 people had to adopt a responsible digital strategy by January 2025.
For Sprout: The public sector is first; procurement criteria for suppliers follow.
B2B SaaS at about 90% gross margin. A free scan opens the door; monitoring is the first sale; fixes and the builder grow every account.
A year spent per company today: ~$200K on reporting (PepsiCo), ~€180K per department on new sites (Sanitas). Entry ~€12K a year
Per agency, growing as they bring more clients onto Sprout
