Products we build and run.

WinstarIT designs, builds and operates its own technology products — the platforms a real-estate business runs on, and the stack its marketing runs on.

Talk to us about a product

01 Why our own

We run what we build.

Everything a real-estate business needs online, from one team — the marketing that brings the buyer, the content that sells the property, and the software that runs the sale.

  • We run our own products

    Exkoo, PropertyChain and Mailkoo are ours, so we design and build like owners — for the long run.

  • Real estate, understood

    We know how property is developed, sold and managed, and we build for that reality.

  • Engineering first

    Typed code, tested releases and systems built to be maintained, not just launched.

02 Exkoo

Real estate management platform.

One platform to manage a real-estate business — CRM, projects, sales, conversations and campaigns behind a single login, for agencies, brokers and developers.

Built around how property is actually sold, from the first enquiry to the keys.
