About

Built in Hamburg, hosted in Frankfurt.

Our story

Founder letter

Senorit was founded in Hamburg in 2019, not as a startup idea but from a concrete problem. As a web agency, we had too many tools in use: one for project management, one for time tracking, one for invoices, one for client communication. Every interface between these tools cost time and produced errors.

What started as an internal tool grew with every client project. In 2023 it became clear that the problems are not unique to agencies. Law firms had the same island solutions, retailers had the same manual reconciliations, creators had the same tool overload. That was the moment an internal system became a product.

MicroSenorit is not a hype product. No venture round, no growth targets at the cost of product quality, no AI promises that do not hold. Four modules, because those are the four real use cases we know from years of agency work. Built by a small family business that knows its customers personally and responds personally.

We are registered for standard VAT, not small business exemption. We issue proper invoices under German law, pay tax correctly and treat data protection as a technical and organisational baseline, not as marketing text.

If you test MicroSenorit and have questions, you reach a person, not a bot. That remains so as long as we are small enough to keep it that way.

Principles

Three principles

GDPR taken seriously

All data in Frankfurt. No US cloud transfer. Processing agreements with all sub-processors. No grey areas, no opt-out language buried in long texts.

No investor, no exit

No external investor, no exit pressure, no growth at any cost. The product is built to work and be maintainable in ten years.

Stable over months

No major redesign every 18 months. No feature that disappears after a year. API versions remain backwards-compatible. User habits are respected.

History

  • React 19 with Server Components
  • TypeScript strict mode throughout
  • Supabase PostgreSQL with Row Level Security
  • Drizzle ORM with full migrations
