Dynamic pricing for businesses that sell time slots

Booko helps businesses that sell bookable time slots make more money by dynamically pricing their time. Unlike physical inventory, unsold time slots disappear forever, yet most time-slot-based businesses still rely on static pricing. We integrate with existing booking systems to adjust prices and incentives based on historical utilization, availability, and demand. Early customers see ~20% revenue uplift by selling time that would have otherwise gone unsold.

TLDR: Booko is a pricing engine for businesses that sell time slots that uses dynamic pricing to fill more appointments during slow times (similar to how airlines and Uber price unused capacity).

We’d love to speak with decision makers at any time-slot-based businesses that want to maximize their revenue! Booko is a great fit for any high fixed-cost business that’s selling their time. Some examples include: class-fitness studios, med-spas, tutoring centers, consultants, personal trainers, movie theaters and event venues, hair salons, accounting firms, and other appointment-based businesses with uneven demand.

Problem/Solution:
Time-slot based businesses all face the same issue: every unsold hour is $0 revenue. Demand is often uneven, and existing tools give customers no incentive to choose those slower times.

Booko integrates with existing booking systems to automatically adjust prices and incentives based on historical utilization, real-time availability, and demand. Like airlines or Uber, we price unused capacity while staying inside the business’s existing workflows. Early customers see around a 20% revenue lift by filling time that would have otherwise gone unsold.

Booko works anywhere people sell their time, from fitness-studios and med-spas to tutors, consultants, and professional services.
