Tim Craggs is building technology that could change how we understand disease.

In this episode of The Digital Forge, David Richards MBE sits down with Tim Craggs, founder and CEO of Exciting Instruments, a University of Sheffield spin-out developing a new generation of tools for single-molecule research.

What once required vast, expensive machines in specialist labs can now sit on a benchtop. That shift matters. Tim explains how being able to observe single molecules in action opens the door to earlier disease detection, better drug discovery, and eventually new ways of tackling conditions like Parkinson’s.

But this is not just a story about science. It is a story about conviction and risk. Tim talks candidly about funding the business through customer sales before raising capital, scaling a deep-tech team at speed, and moving from academic research into global commercial markets in pharma and biotech.

We explore what it takes to build hard technology in the UK, why first-principles science still matters, and how Sheffield is quietly producing tools that could help reshape modern medicine.

This is a conversation about patience, precision, and building technology that may one day help cure diseases we still struggle to understand.

In this episode of The Digital Forge Podcast, David Richards MBE sits down with Dan Ridsdale, Head of Technology, Media and Telecoms at Edison Group, to get inside the mind of the modern tech investor. After more than 25 years analysing listed technology companies and working with management teams across the UK and Europe, Dan has a rare view of what really moves markets - and what does not.

This conversation goes beyond valuation jargon and earnings calls. Dan and David unpack how investors actually build conviction, why some founders cut through while others never get noticed, and what a compelling “equity story” looks like from the other side of the table. They dig into the state of UK public markets, why ambitious growth companies so often feel overlooked, and what needs to change if Britain is serious about backing its own tech and industrial champions.

In this episode, they explore:

• How a career in telecoms software and market analysis led Dan into equity research

• What institutional investors really look for in a tech or industrial company

• The biggest mistakes founders make when pitching to the market

• How to tell a clear, credible growth story that resonates with investors

• The challenges and opportunities for UK-listed tech and industrial businesses today

• Practical advice for northern and regional companies trying to attract serious capital

A candid, practical guide for founders, CFOs, and anyone who wants to understand how investors think before they step into the City.

Bruce Katz is one of the most influential thinkers on cities and metropolitan economies. He has advised US Presidents Bill Clinton and Barack Obama, shaped national policy, and helped city leaders around the world rebuild their economies from the ground up.

In this episode of The Digital Forge, David Richards MBE sits down with Katz for a wide-ranging conversation about the future of place, power and production. Katz explains why cities, not national governments, now lead the way on innovation and growth, and why the next industrial era will be driven by regions that know how to combine research, talent and manufacturing.

Together they explore the lessons from America’s reindustrialisation, the rise of advanced manufacturing districts, and what South Yorkshire must do to compete with global leaders in clean energy, aerospace, defence and deep tech. Katz also reflects on the South Yorkshire Growth Plan and why the region is better positioned than most to seize the new economic moment.

This is a conversation about strategy, capital and the renewal of industry.
