TapStack is the company and team behind Tapni, MailSign, Siteio, and more — building tools that make everyday work simpler, and the backend platform they'll all run on.
Independent products, one team. Each solves a real problem — and shares the same craft.
Digital, NFC-powered business cards. Share your contact details, socials, and links with a single tap — your business card is now an app.
Professional, customizable email signatures for teams and individuals. Design a polished, on-brand signature in minutes.
The visual, AI-assisted website builder. Design and ship modern sites fast — it's the platform this very page is built on.
We're always building. New products join the stack when they're ready to make something simpler.
TapStack is becoming a product in its own right: a backend-as-a-service platform that powers Tapni, MailSign, Siteio, and everything we build next.
One foundation for authentication, data, APIs, and infrastructure — so every product in the stack ships faster and stays reliable. We're building it for ourselves first, then opening it up.
One secure login layer across every product.
Managed databases and storage, ready to use.
A consistent API surface for building fast.
Scalable hosting and infra, handled for you.
We're a product company at heart. TapStack is the team behind Tapni, MailSign, and Siteio — designers and engineers who like shipping useful things and sweating the details.
Different products, one standard for quality. That's the whole idea.
Partnerships, press, or just curious about what we're building — we'd love to hear from you.
