Tom Ridges's biography

At a glance

  • Founder and CEO of behavioural science platform Herdify
  • Expert on herd mentality and how decisions truly spread
  • Former technology strategist at Microsoft

Tom Ridges is the founder and CEO of Herdify, a behavioural science platform that helps brands and charities harness the power of offline word-of-mouth to drive growth through his data-driven insights.


With 20 years of experience spanning startups to Microsoft, Tom has built expertise in network theory, data analysis, and AI applications. He founded Herdify after recognising the gap between online reviews and genuine human recommendations, turning his experience of a personal frustration into a business solving how influence actually spreads in the real world.


Tom helps organisations understand the mechanics of herd mentality and decision-making beyond digital metrics. His work reveals how people truly influence each other through offline conversations and social networks, providing practical frameworks for identifying and activating genuine advocates. By combining behavioural science with technology, Tom shows how to measure and amplify the recommendations that matter most, the ones happening away from screens and algorithms.


Audiences leave Tom's presentations with actionable strategies for building authentic word-of-mouth programmes, methods for identifying real influencers within their networks, and frameworks for understanding how decisions spread through communities rather than through marketing channels alone.


Tom brings clarity to the often misunderstood world of human influence, translating complex behavioural science into practical growth strategies for any organisation.

Does PepTalk charge a booking fee?

No. PepTalk adds no booking fee, so you pay the speaker's fee and nothing beyond it. The service, from shortlist through to contracts and event-day logistics, is included. For repeat or multi-event bookings, PepTalk can agree preferential rates with your procurement team.

What happens after I send a brief?

Share your event date, audience, format, objectives and budget, and PepTalk sends a hand-picked shortlist within 24 hours. Each suggestion comes with a profile, a fee and a recommendation on the strongest fit. Once you choose, PepTalk handles contracts, travel and logistics through to event day.

What does the typical fee range mean?

The typical fee range is the speaker's standard in-person fee in their home market, shown in their local currency. It moves with format, location, date and session length: virtual sessions and shorter slots usually cost less, while international travel and peak dates cost more. Send your brief to PepTalk and the team will confirm the exact fee in your currency.

Have all the speakers on the website worked with PepTalk before?

Not all of them, and it makes no difference to your booking. PepTalk's network of 15,000+ speakers covers talent the team works with directly alongside speakers represented by agents and agencies worldwide. PepTalk approaches the speaker, negotiates the fee and handles contracting either way.

How far in advance should I book a speaker?

Three to six months ahead is comfortable for most events, and 12 months is better for large conferences, peak-season dates or one specific in-demand speaker. Shorter timelines are workable, and PepTalk regularly fills last-minute and replacement bookings within days. Availability is the constraint, so get in touch as soon as you have a date.
