Grassroots sport in London, running on something other than luck.
Club House OS and the Player OS are two halves of one system, built to fix how clubs grow and how players find them.
The problem
Most grassroots clubs run on volunteers with a full-time job elsewhere. They don't have the time or the marketing background to grow, and the tools built for players — session finders, listing sites — don't touch that. Players give up on finding a session for a different reason: the information about it lives across an Instagram account, a WhatsApp group, and word of mouth, never in one place.
Why we're doing this
This isn't a market a spreadsheet pointed us at. Twenty-five years playing, coaching, officiating, and volunteering in grassroots sport in London means watching good clubs stall or fold for a reason that has nothing to do with how good they are at the sport itself — nobody had the hours left over to also do outreach, chase a sponsor, or keep a calendar current. The idea sat around for the better part of two decades before there was a real way to build it. Ten years in marketing after that is what made it buildable.
What we got wrong at first
The NBRH started as a two-sided marketplace: help players find sessions, help clubs get booked. A pilot showed the first half wasn't the real problem — players found workarounds, clubs didn't. Discovery already has decent tools built for it. What clubs lack is capacity: someone to do outreach, chase sponsors, and keep a session calendar current. So the platform got rebuilt around clubs as the side that pays, with free player discovery as the layer that feeds it.
How we do it
Every club, venue, league, and session in the directory gets checked before it's trusted. Nothing is pulled in once and left to go stale — each entry carries a confidence rating, from verified down to unconfirmed, and gets rechecked over time rather than sitting as a dead listing. It's slower to build this way than taking a one-off data pull, but it's the difference between a directory and a spreadsheet nobody trusts.
Two products, one system
Club House OS
A self-serve platform for clubs — outreach, sponsorship leads, and the tools to run day-to-day without hiring for it.
The Player OS
Free, and staying that way — sessions, clubs, and leagues in one search, feeding the same dataset back into Club House OS.
What this actually saves you
Time
Hours back each week not spent drafting outreach messages, chasing replies, or hand-updating a session calendar.
Effort
No need to become a marketer, a data analyst, and a salesperson on top of actually running the club.
Money
No agency retainer and no ad spend to reach players who are already looking for a club like yours.

Where this goes
The directory gets more useful the more clubs and players put into it, and that's the actual asset — not another session finder, but a live, verified picture of grassroots sport in London that gets harder to copy the longer it runs.
