Hello. We’re Teya.

Teya was founded on a simple belief: local businesses deserve better.

They are the cafés, restaurants, salons, shops and entrepreneurs that bring character to our high streets, create jobs and keep communities moving.

Teya exists to change that.

We’re building a financial platform for local businesses across Europe – one built around simple tools, thoughtful design and real human support. Our Members rely on us to help them run their business with confidence, and that responsibility shapes the way we work.

If you want to build meaningful products, solve real problems and make a genuine difference for local businesses, we’d love to hear from you.
