No, PepTalk doesn't charge a booking fee. You pay the speaker's fee plus any travel and expenses, which PepTalk confirms upfront in your quote. The shortlist, contracting and event-day logistics are included. For repeat or multi-event bookings, PepTalk can agree preferential rates with your procurement team.
PepTalk sends a shortlist of matched speakers within 24 hours, each with a profile, a fee and a recommendation on the strongest fit. The more you share about your date, audience, format, objectives and budget, the closer the match. Once you choose, PepTalk handles the contract, travel and logistics through to event day.
The typical fee range on a PepTalk speaker profile is a guide to what that speaker usually costs for an in-person event in their home market, shown in their local currency. The final fee depends on format, location, date and session length. Virtual and shorter sessions usually cost less, and international travel and peak dates cost more. PepTalk confirms the exact fee in your currency once it has your brief.
No. PepTalk represents 15,000+ speakers, hosts, comedians and entertainers, some booked directly and others through their agents and agencies worldwide. The process is the same for all of them: PepTalk checks availability, negotiates the fee and manages the contract and logistics.
Book a speaker three to six months before your event. Allow 12 months for large conferences, peak-season dates or a specific in-demand name. PepTalk also fills last-minute and replacement bookings, often within days, so get in touch as soon as you have a date, even at short notice.
