About us

Closer is an AI-powered website builder designed for micro, small, and medium-sized businesses. Made for people who are brilliant at what they do, but have no interest in learning web technology. People who want a great website that actually works for their business: bringing in customers, supporting sales, and growing their bottom line.

We take care of the technology so you never have to.

Our story

Closer was founded in 2023 by Sergey Kotyrev — a serial entrepreneur with over 20 years in web technology.

Sergey launched his first web company (an internet agency) back in 2000. In 2008, he founded Umisoft, the company behind UMI.CMS and the UMI website builder — two of the leading website platforms in the Russian-speaking internet, backed by a partner network of around 3,000 web developers. To date, over 1.8 million websites have been built on the UMI platform.

In 2022, Sergey relocated to Israel and set his sights on the global market. The result is Closer — a platform built on the most advanced AI technologies available today, designed to bring the best of the web within reach of every business owner, anywhere in the world.

We believe people do their best work when they focus on what they love — and what they're genuinely good at. For you, that's running your business. For us, that's building the technology that makes it thrive.

Closer exists so that any business owner can have a beautiful, effective website — one that drives real results — without needing to understand the technology behind it, spend a fortune on developers, or settle for something that doesn't quite fit their needs.

With Closer, you get the website your business needs. Not the one a developer suggested. Not whatever a generic template offers. Yours.

Our AI builds a professional, polished site for you from scratch (or redesigns your old one) — writing the copy, generating the visuals, and structuring everything to convert visitors into customers. You refine it to match your vision, and walk away with a powerful tool for growth.

Smart technology. Real results. Built for your business.

We love music. We believe it is one of the few things in life that truly matter. It fills the world with meaning, texture, and colour.

One album, above all others, has stayed with us: Closer by Joy Division. Raw, timeless, and unlike anything before or since — it has quietly inspired generations of musicians, artists, and makers who you almost certainly know and love.

When we set out to build a new product, we wanted to pour that same heart and soul into it. Not just useful — but alive. Something crafted with intention, built to last, and capable of moving people. So that's the soul behind the name Closer. And in some way, the soul behind the product.

This is the way. Step inside.
