Who you’ll work with
Ben Jones, founder of Keystone Dynamics Group

Ben Jones · Founder

Hi, I’m Ben.

I built WarmNote because my mother kept her feelings private when I asked. Now she shares how she’s feeling in a few taps, and I know how she’s really doing, not just ‘I’m fine’.

I bring that same care to growing businesses ready to fix what’s slowing them down, and you work directly with me, never a number in a queue.

Let's build yours

Three ways to work with us. Fixed scope, fixed price, agreed up front so there are no surprises.

For example

  • A one-page site that turns visitors into enquiries
  • A bot that answers your most common question
  • Your enquiry form feeding straight into your CRM

Software with a few moving parts, built, tested and handed over. Scope agreed up front, so no surprise invoices. Your first 90 days of support are included.

For example

  • A booking system that takes payments and sends reminders
  • A dashboard that replaces your spreadsheets
  • A bot that turns enquiries into finished reports
  • AI that reads and sorts your incoming messages

A multi-month engagement for businesses ready to commit to a full custom build. Your first 90 days of support are included.

For example

  • An app your customers download and log into
  • A platform you charge a subscription for
  • Custom software to replace the clunky system you're stuck with

* Starting prices. Exact scope and price confirmed in writing before we start. Prices exclude VAT (charged at 20%).
