Not necessarily. While the speakers listed on our website may not have worked with PepTalk in the past, they are recognized professionals in the industry and known to engage in similar events and engagements. We work with a wide variety of speaker agents and talent agencies to ensure we have the best selection of speakers, hosts, comedians and entertainers available.
We do not accommodate requests for birthday messages or any other personal, non-commercial contact with the speakers, comedians or entertainers.
We work with speakers across a variety of fee ranges, giving you the flexibility to choose someone who fits your event's needs. Virtual keynote fees in the UK and Europe typically start at £2,000, while in-person top-tier speakers can reach £25,000. In the US, virtual in-person fees range from $5,000 to over $100,000, depending on the speaker and format, such as after-dinner talks, conference keynotes, Q&As, or podcasts. Comedians generally start at £1,500 or $2,000 for a 20-minute set.
Our goal is to help you find the speaker who best matches your event’s goals and budget. We take the time to understand your event, objectives, and audience to recommend the right fit. The most expensive option isn’t always the best one, and our priority is finding the ideal speaker or expert for your needs; not the highest-priced one.
