Booko

Booko is a Y Combinator-backed company that dynamically pricing the whole economy. The company participated in the Winter 2026 batch of Y Combinator.

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.

Booko was part of Y Combinator's Winter 2026 cohort, has a team of approximately 2 employees, and is actively operating.
