Chalkstream Digital — Software, crafted differently

Built from the riverbank

Chalkstream Digital is the practice of Duncan Soar — developer, investor, and photographer — working from a converted mill on Wiltshire's River Avon. The chalk streams of the Avon valley inspired the name. The software speaks for itself.

Every product in our portfolio started as a personal itch: a better way to track investments, a tool to teach kids about money, a marketplace to connect photographers with assistants. We build what we use, and we use what we build.

Need an AI colleague
for your business?

We don't just use AI in our own team — we place expert AI staff members in other businesses too. Through Capable Colleagues, our AI staffing service, you can hire a dedicated AI team member with a defined role, persistent memory, and the ability to communicate with your team on WhatsApp.

They learn your business, remember your customers, and get smarter every week. Same technology that powers our own team — available for yours.

A different kind of team

Chalkstream Digital runs on a model we think is the future of small practices: one human founder working alongside a team of specialist AI colleagues. They're not chatbots. They're not assistants. They're team members with defined roles, persistent memory, and the ability to communicate and collaborate with each other internally.
