Why your old website isn't working anymore
The average small business website is 4-7 years old (according to W3Techs, 43% of the world's sites use WordPress, most of which run on older themes). Typical issues with such sites include:
- Lack of mobile-friendliness – Google indexes mobile-first (Google Search Central)
- Slow loading speeds – Core Web Vitals do not meet requirements
- Non-compliance – Fails to meet WCAG 2.2 or GDPR standards
- Outdated design – Users leave within 2-3 seconds
The classic solution: 3-12 months of development, €3,000-€15,000. Our alternative solution: 1 minute, start for free.
What is Sosei.site?
Sosei.site is an AI-powered website generation platform created by our team. It has two main use cases:
1. Old site → New in a minute
Enter your existing website URL. Sosei AI: - Scans your content, structure, brand colours, and logos - Analyses your products/services - Generates a completely new, modern version – mobile-friendly, fast, and SEO-optimised - Preserves all essential information while providing a fresh design
The result is ready to view in under 60 seconds.
2. No site yet? AI creates one
If you don't have a website yet: - Describe your business and goals in a few sentences - Choose a style (minimalist, bold, playful, B2B-professional) - The AI creates a site exactly in the style you like - You add your own content, logos, and contacts
How does it work technically?
Sosei uses a combination of: - Web scraping – extracting content from your current site - LLMs (Large Language Models) – restructuring and optimising content - Image AI – regenerating images if necessary - Design system – dozens of ready-made high-end templates - Code generation – ensuring fast, accessible HTML/CSS
The result is a static, fast, and Core Web Vitals-compliant site.
Who is Sosei for?
✅ Suitable for: - Small business owners wanting a quick modernisation - Startups needing an MVP now - Freelancers and consultants - Restaurants, salons, and small shops - Brochure-style B2B sites (5-15 pages)
❌ Not suitable (choose a custom solution instead): - Complex e-commerce (1000+ products, multi-language) - Various integrations (CRM, ERP, accounting software) - Client portals with logins - Special compliance requirements (HIPAA, PCI Level 1) - Multi-site or headless architecture
What if Sosei isn't the right fit?
Then we can create a custom solution with our team. Two approaches:
A) AI-assisted custom development We use AI for rapid prototyping and boilerplate code, but the architecture, complex logic, and integrations are handled by developers. **Faster and more affordable** than classic development, but fully customised.
Typical project: 2-6 weeks, €2,000-€8,000.
B) Classic custom build (manual) If you have very specific requirements – high security, regulatory needs, complex integrations – we build the code manually. Slower, but offers **maximum control and quality**.
Typical project: 6-16 weeks, €5,000-€25,000.

Practical example
Recent case study: A client's WordPress site from 2019 was slow (LCP 6.2s) and not WCAG-compliant.
Sosei version (90 seconds): - LCP 1.1s ✓ - Mobile-friendly ✓ - WCAG AA level compliant ✓ - All content preserved
The client used the Sosei version as a draft, and our team finalised a few specific elements (broker calculator, multilingual support). Total cost: under €1,500, completed in 5 days.
