Sort Your Brain Out
The brain is capable of far more than most people realise, but bad habits and inefficient thinking patterns often get in the way. Dr Jack Lewis shares 12 practical, science-backed techniques to boost cognitive function, improve focus and enhance mental agility. His Brain Optimisation Principles have been embraced across industries, from finance to pharmaceuticals, helping professionals sharpen their thinking and achieve more. Audiences will discover how small daily changes can lead to significant improvements in performance, creativity and resilience.
The Neuroscience Of Decisions: Sales & Negotiation
Every decision is shaped by subconscious evaluations of risk, reward and uncertainty. Dr Jack Lewis unpacks nearly two decades of neuroeconomic research to reveal what drives human decision-making. His insights have helped businesses refine their sales strategies and even secure multimillion-pound contracts. From influencing client choices to strengthening negotiation tactics, this session equips professionals with the tools to align customer decisions with business goals and dramatically improve their success rate.
The Science Of Creativity
Creativity isn’t just a gift - it’s a process that can be optimised. Drawing on both historical inspiration and cutting-edge neuroscience, Dr Jack Lewis explores how to unlock innovative thinking and problem-solving. His evidence-based “Brain Shaking” technique has helped teams across industries - from media to engineering - consistently generate breakthrough ideas. By challenging conventional brainstorming methods and adopting smarter strategies, organisations can cultivate a truly innovative culture and gain a competitive edge.
Building Resilience
High-pressure environments demand resilience, yet chronic stress can erode mental and physical health. Dr Jack Lewis examines the neuroscience of stress, explaining how to harness its benefits while avoiding burnout. With a focus on practical daily habits and mindset shifts, he provides a roadmap for maintaining peak performance without the long-term costs of stress overload. Whether in leadership roles or frontline positions, attendees gain the tools to strengthen their resilience and sustain high levels of productivity.
Understanding And Reducing Unconscious Bias
Unconscious biases shape perceptions and decisions in ways most people fail to recognise. Dr Jack Lewis reveals the psychological mechanisms behind these hidden prejudices, offering evidence-based strategies to mitigate their impact. His engaging approach - combining cutting-edge research with real-world examples - makes this an eye-opening and essential session for any organisation striving for genuine inclusivity. By addressing biases at their source, businesses can foster fairer, more effective decision-making and create a truly equitable workplace.

Testimonials

I would like to recommend Dr Jack Lewis. We chose Dr Jack to be the lunchtime speaker at our Smartcomm Technology Day earlier this year. He engaged with our audience really well and his presentation was filled with useful information, hacks and ‘aha’ moments.

His talk was so engaging there was a queue of attendees wanting to chat with him afterwards. Dr Jack kindly stayed behind to chat with our guests, which made their day extra special.

You'll receive a hand-picked shortlist within 24 hours of sharing your brief. Each suggestion comes with profiles, fees, and PepTalk's recommendation on the strongest fit. If you need options sooner for an urgent event, say so and the team will move faster. Start at getapeptalk.com.

Most bookings can be rescheduled with reasonable notice. Cancellation terms vary by speaker and are set out clearly in the contract before you confirm, so there are no surprises. PepTalk's team supports you through any change. Contact hello@getapeptalk.com as soon as plans shift.

Can PepTalk help plan the speaker programme for my event?

Yes. Beyond booking a single speaker, PepTalk helps shape a full programme, matching voices to your agenda, audience, and goals across a day or a series. It is a consultative service, not just a booking. Tell us about your event at getapeptalk.com.

Speaker fees vary based on factors like event location, format, and availability. The 'typical fee range' figure gives you a baseline of someone's local, in-person rate sits, and we'll confirm the exact fee when you get in touch.

What logistics should I prepare before my speakers arrive?

Before your speakers arrive, confirm AV is tested, a green room is ready, and printed schedules are on hand. Prepare warm introductions for each speaker and brief your team on timings. PepTalk speakers come fully briefed, making event-day logistics smoother and stress-free from the start.

What's the difference between a keynote speaker, an MC, and event entertainment?

A keynote speaker delivers an inspiring or informative talk. An MC hosts and guides the event, keeping things on track. Entertainment — like a band or comedian — creates atmosphere and fun. Each serves a different purpose, and PepTalk can help you book the right talent for all three.

What happens if I need to cancel or reschedule a speaker booking?

Life happens! Most speaker bookings can be rescheduled with reasonable notice. Cancellation terms vary by speaker, but PepTalk handles all the details & contracts transparently upfront so there are no surprises. Our team supports you through any changes, making the process as smooth as possible.

What information do I need to provide when booking a speaker?
