The booking system built for saunas and wellness.
Timed sauna sessions, yoga classes, private hire and gift vouchers, with every space counted and every guest’s health questions answered before they arrive.
The bit that wears you down.
Every session has a handful of spaces and they all go at once.
Gift vouchers are your best seller and the hardest to keep track of.
Health questions get asked on the day, if at all.
Built for how saunas and wellness spaces work.

One system for bookings, kit, staff, customers and payments, set up around the way you run your day.
Timed sessions with set spaces
Every session has its own capacity, so it can never overbook.
Classes and one-offs together
Yoga classes, sauna sessions and workshops side by side on one calendar.
Private hire
Sell the whole sauna or studio as a private booking alongside shared sessions.
Gift vouchers that sell
Vouchers sold and redeemed on your own site, with no separate voucher tool.
Health questions before arrival
Online forms with your own questions, signed before anyone arrives.
Sea saunas timed to the tide
Set tide and weather conditions for seafront sessions.
“The whole thing is significantly more comprehensive and joined up than I anticipated. It sounds like you guys are actually listening to what centres need.”
“This is far more tailored. My current system is a one-size-fits-all and takes in a huge variance of types of activity. Yours is far more tailored, which is exactly what we need.”
“You guys have been busy. You guys have got a lot of stuff that our current system doesn’t do.”
“You can tell you guys are obviously in the outdoor business because it is very comprehensive.”

We’re experts at turning visitors into bookings.
We run the adventuro marketplace, so we see every day what makes people book an adventure and what makes them leave. Slipstream puts that know-how to work for your centre, and our team is there to help you grow, not just hand you a login.

Booking that converts
Customers pick a date, choose their options and pay on your own site, without a detour to someone else’s.
10pm on a Tuesday, a family books Saturday’s surf lesson for four from the sofa.
An AI agent that sells
It answers the questions that usually lose a booking, then books them in, even while you’re out on the water.
“Do I need to be able to swim?” answered from your own activity details, then booked.
Websites built to sell
Fast, mobile-first sites with your activities front and centre and booking on every page.
Every activity page shows the next dates with spaces and a Book now button.
More places to be found
Your activities on the adventuro marketplace, in front of people already searching for them.
Someone looking for coasteering in Cornwall finds your sessions and books on adventuro.
Switching is the easy part.
We move you over
Your products, pricing and customers come across from your current system. You don’t start from scratch.
Run both side by side
Keep your old system going while Slipstream beds in, and switch when you’re happy.
No long-term contract
No lock-in. You stay because it works for your centre, not because you have to.
The things centres ask us first.
Anything else, just ask on a demo.
Can we limit the number of people in each session?+
Yes. Every session has its own capacity across your website, the marketplace and bookings you take yourself.
Can we sell gift vouchers?+
Yes. Vouchers are sold and redeemed on your own site, with no separate voucher tool.
Can we ask health questions before people arrive?+
Yes. Guests answer your own questions online and sign before their session.
Can we offer private hire as well as shared sessions?+
Yes. Sell private hire as its own option alongside your shared sessions.
What does Slipstream cost?+
One monthly subscription plus a small share of the bookings you take through it, in place of the separate tools you pay for today. We’ll talk you through what it would look like for your centre on a demo.
Can you move us over from our current booking system?+
Yes. We move your products, pricing and customers into Slipstream for you, and you can keep your current system running alongside until you’re ready to switch.
Am I tied into a long contract?+
No. There’s no long-term contract.
