What Booko does

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.

Describe what your company does in 50 characters or less.

Dynamically pricing the whole economy.

What is your company going to make? Please describe your product and what it does or will do.

We build software that helps businesses selling bookable time slots raise prices dynamically based on demand, availability, and historical data. It plugs into their existing booking systems and automatically adjusts prices to sell time that would otherwise go unused.

Where do you live now, and where would the company be based after YC?

We live and work in San Francisco, CA. If accepted, Booko will continue to be based here after YC.

Explain your decision regarding location.

San Francisco has the talent and ecosystem we need to build and grow Booko. Both founders already live here, so it's natural to continue operating from here.

Is this the real Booko YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Booko's public data (launch notes, founder backgrounds, product description). It shows how a company like Booko would present itself to YC, not the text they submitted.
