Job Description

Our mission is to Build the future of Digital ID and user verification. The future of user verification is privately easy to use. Making user verifications smooth for both users and companies. Giving data ownership back to their owners.

What We Do

Have you ever had to take pictures of your documents and a selfie to use a service?

Do you know who has access to your ID?

Wouldn’t it be awesome to have your ID privately secure in a safe place, and get verified without having to take pictures every time and keeping track of who has access to your ID? That’s right, you guessed it, that’s what Silt does.

Silt is a digital ID that helps users get verified to use services without having to take pictures every time of their docs. We do it with our proprietary Artificial Intelligence and a Digital ID that verifies user’s pictures under 6 seconds the first time, and allows them to reuse these pictures for the future verifications for other services. This way users have their ID privately secure in one place and can smoothly get verified without taking pictures of documents every time. Something like “The Paypal of verifications”, like some customers of ours say.

Aside from user verification (KYC), we also verify companies automatically (KYB), and process other documents, such as income statements, proof of residence and bank receipts. This way we can make our customer’s scalable thanks to a 100% automatic onboarding.

Our customers can be delivery companies, car rental companies, property rental, sharing economies such as motosharing, digital insurances, and others.

Come to the Silt side

We believe in the “give and you will receive”, and that’s why we give total freedom and confidence to our people. We are remote 100%. Although we encourage you to see this beautiful world, we can provide office space wherever you may be based if you need it.

We have won some awards like Parlem Ventures and Startup Capital and we are also incubated in Lanzadera.

We cannot wait to become the standard of Digital ID of Europe. Help us get there! 💪
