Builds a dynamic pricing engine for businesses that sell time slots, using real-time supply/demand signals, booking velocity, and utilization trends to fill more appointments during slow periods. Think Uber/airline pricing for salons, fitness studios, med-spas, and service businesses.
Officially launched March 2026 with integrations for booking platforms. Pricing engine uses live supply/demand signals, booking velocity, time-of-day trends, and operator-defined min/max thresholds. Businesses maintain full control over pricing boundaries. Targeting salons, fitness studios, med-spas, tutoring, consultants, movie theaters, and event venues.
The service economy has digitized marketing, payments, and booking but not pricing intelligence. This is a clear analogy to airline yield management applied to a massive fragmented market. 19-year-old founders from Dartmouth with relevant pricing experience (Joby/Uber Elevate) and marketing agency background.
<p>Real-time ML-driven dynamic pricing that automatically adjusts appointment costs based on live supply, demand, and booking velocity to maximize revenue and utilization.</p>
It's like surge pricing for your haircut — except smarter, fairer, and designed to fill every empty chair.
Booko's core ML engine continuously ingests real-time signals including current booking fill rates, time-of-day demand curves, historical utilization patterns, booking velocity (how fast slots are filling), and cancellation rates. The model dynamically adjusts prices within operator-defined minimum and maximum thresholds, raising prices as demand spikes and lowering them to incentivize bookings during slow periods. Unlike static discount strategies, the system reacts in real time — a Tuesday 2pm slot that's historically empty but suddenly seeing interest will reprice upward, while a Friday 5pm slot that's unusually slow will drop to attract last-minute bookings. The continuous feedback loop means the model improves with every transaction, building a compounding data advantage. Early adopters report approximately 20% revenue uplift within two weeks, suggesting strong price elasticity signal capture even with limited initial training data.
It's like how airlines price seats — except instead of flying to Denver, you're getting a facial, and instead of a billion-dollar revenue management team, it's two 19-year-olds and a very clever algorithm.
<p>ML-powered demand forecasting that predicts future booking patterns to proactively optimize scheduling, staffing, and promotional strategies.</p>
It predicts when your business will be slow before it happens, so you can fill those gaps instead of staring at an empty appointment book.
Beyond real-time pricing, Booko's ML models analyze historical booking data, seasonal trends, day-of-week patterns, local event calendars, and cancellation/no-show rates to generate forward-looking demand forecasts for each time slot across a business's schedule. These forecasts power proactive recommendations: the system can automatically generate targeted promo codes via Twilio-powered SMS or email campaigns to drive bookings during predicted low-demand windows, or suggest staffing adjustments to operators. The forecasting layer also feeds back into the dynamic pricing engine, allowing prices to be set preemptively rather than purely reactively. For example, if the model predicts that the week after a holiday will see a 40% demand drop for a fitness studio, it can begin lowering prices and triggering incentive campaigns days in advance rather than waiting for empty slots to appear. This predictive capability transforms service businesses from reactive schedulers into data-driven demand managers.
It's like having a weather forecast for your appointment book — except instead of telling you to bring an umbrella, it tells you to send a 15%-off text to your regulars before the storm hits.
<p>ML system that continuously learns individual customer and segment-level price sensitivity to auto-generate and target personalized incentives like promo codes, credits, and discounts.</p>
It figures out exactly how much of a discount each customer actually needs to book — no more giving away money to people who would have paid full price anyway.
Booko's incentive engine goes beyond blanket discounting by building and continuously refining price elasticity models at the customer segment and individual level. As customers interact with dynamically priced slots — booking at certain price points, abandoning at others, redeeming promo codes, or responding to SMS offers — the system learns each segment's willingness to pay and discount sensitivity. This enables hyper-targeted incentive generation: a price-insensitive loyal customer might receive a small loyalty perk rather than a deep discount, while a lapsed customer showing browse-but-don't-book behavior might receive a precisely calibrated promo code just large enough to convert them. The system also runs continuous multi-armed bandit experiments across discount types (percentage off, fixed dollar amount, credit toward next visit, class pack upgrades) to learn which incentive formats drive the highest conversion per dollar spent. Over time, this creates a virtuous cycle where the business spends less on discounts while converting more bookings, directly improving unit economics. This capability is particularly novel in the service economy, where most competitors still rely on static, one-size-fits-all promotions.
It's like a bartender who knows exactly which regular needs a free drink to stay loyal and which one would order anyway — except it does this for thousands of customers simultaneously without the small talk.
