Member Splash — The Platform Built for Swim & Tennis Clubs
A New Era Begins for Club Management
For sixteen years, Member Splash has sat at the center of how swim and tennis clubs operate. Hundreds of clubs. Thousands of board members, treasurers, membership chairs, and front desk volunteers. Millions of check-ins, dues payments, reservation bookings, and guest passes.
We have heard every pain point. Fielded every middle-of-the-night support request. Shipped feature after feature based on what clubs actually needed — not what looked good in a product roadmap deck.
And after sixteen years of listening, one thing became clear: incremental updates weren’t going to be enough.
The way clubs operate has changed. Members expect a mobile experience. Boards are asking harder questions about retention and revenue. Volunteer burnout is real. The gap between what modern clubs need and what their software can deliver has never been wider.
We didn’t patch that gap. We built something new.
Not an update. A new version — purpose-built, from the ground up, for the way your club actually runs.
Introducing Member Splash
Member Splash OS is a software platform built exclusively for aquatic and recreation clubs.
Not adapted from general association software. Not repurposed from HOA management tools. Built from the ground up for the way your club actually runs — with a member-owned structure, a volunteer board, a seasonal operating calendar, and a community that’s been together for decades.
Every layer knows what every other layer knows. Every action a member takes, every reservation booked, every dues payment collected, every check-in logged — it all flows into a dashboard that tells your board exactly what’s happening, why it’s happening, and what to do next.
This is Member Splash.
What Makes Member Splash Different?
The difference between software and Member Splash isn’t the feature list. It’s what happens between the features.
In a traditional software stack, reservations know about courts. Members know about dues. Payments know about invoices. But reservations don’t know about members. Payments don’t know about retention. Check-in doesn’t know about churn risk.
In Member Splash, every layer understands every other layer.
When a family’s check-in frequency drops, the Membership layer notices. When their payment comes in late, the Financial layer flags it. When both signals appear together, Poseidon AI — the intelligence layer — identifies them as an at-risk family and surfaces a recommendation before they send the resignation email you never saw coming.
When a board member asks why revenue is down this season, they don’t pull three separate reports and try to reconcile them manually. They ask. The system answers — with data, context, and a recommended action.
Reservations. Members. Payments. Staff. Events. Lessons. Facilities. Communications. AI.
One ecosystem. Everything aware.
Meet the New Member App
Your club now has an app. No App Store required.
Members install it directly from their browser in one tap — iPhone, Android, tablet, desktop. It lives on their home screen like any native app. It sends notifications to their lock screen. It works offline.
This is a Progressive Web App. And it changes what your club can do.
Progressive Web App
No App Store submission. No developer accounts. No update approvals. Members install it from their browser, and it behaves exactly like a native app — home screen icon, push notifications, offline access, full-screen experience.
No App Store Required
Your club app is live the moment Member Splash OS goes live for your club. Members tap “Add to Home Screen” from Safari or Chrome, and it’s installed. No download friction, no version management, no platform fees.
One-Tap Install
The install prompt appears automatically when members visit your club portal on mobile. One tap. Done. Works on every major device and browser.
Digital Membership Cards
Every member gets a digital membership card stored in the app. Photo ID included. Works at the gate, at the pool desk, at the snack bar. No lanyards. No laminated cards. No “I forgot it at home.”
Mobile Check-In
Members tap to check in from their phone at the gate. Staff verify instantly on any device. Real-time attendance data flows into Member Splash automatically — no manual entry, no paper lists, no end-of-day reconciliation.
Push Notifications
Reach every member on their lock screen — closures, weather delays, registration reminders, event announcements. No email open rates to worry about. Notifications land the same way a text message does. Members opt in through the app. You control what gets sent.
Mobile Ordering
Members pay at the snack bar, at concessions, at the pool desk — from their phone. No cash, no card fumbling, no line at peak times.
Splash Cards
Splash Cards are prepaid digital accounts members load from home and spend anywhere at your facility. Multiple cards per family. Balance visible anytime. Point-of-sale integration built in.
Reservations
Members book courts, lanes, and any reservable facility directly from the app. Paid or free. Capacity limits enforced automatically. No double-booking, no phone calls to the front desk.
Paid Reservations
Charge for court time, lane rentals, or any facility. Payment collected upfront at booking — no chasing fees after the fact.
Swim Lessons
Members register and pay for swim lessons from the app. Rosters, reminders, and scheduling all included — no separate booking system needed.
Event Registration
Members register for club events, pay entry fees, and receive reminders — all from the same app they use for everything else. No separate event tool. No third-party registration form.
Virtual Lost & Found
Members report lost items and claim found items from the app. Staff manage the lost and found log without a clipboard. AI-assisted matching surfaces likely connections automatically.
Guest Passes
Members purchase and manage guest passes from the app. Capacity limits enforced at check-in. Guest waiver capture included. No paper forms, no manual tracking.
Meet Poseidon AI
Most software companies are bolting AI onto products that were never designed for it. They’re adding a chatbot to a feature list and calling it intelligence.
Poseidon AI is different — and the difference matters.
Poseidon AI is the intelligence layer woven throughout the entire Member Splash OS. It doesn’t sit on top of the platform. It runs through it. Every feature that generates data feeds Poseidon AI. Every recommendation Poseidon AI surfaces is grounded in your club’s actual operational history — not generic advice, not industry templates, your data.
That’s only possible because of sixteen years of cross-club operational data across 470+ clubs in 30+ states. No competitor can replicate that on any timeline.
Here’s what that intelligence looks like in practice:
AI Scheduling
Poseidon AI learns your facility’s demand patterns. It surfaces recommendations for schedule optimization based on how your members actually use your courts, lanes, and facilities — not how you think they do.
AI Availability Builder
Describe your facility rules in plain language. The AI builds your availability schedule across courts, lanes, and any facility. Configuration that used to take hours takes minutes. Review, adjust, publish — you stay in control.
AI Communication
One-click generation of renewal emails, win-back sequences, event announcements, volunteer recruiting campaigns, sponsorship outreach, and board updates. Your club’s voice, your club’s data — drafted instantly, reviewed by you, sent when you’re ready.
AI Reporting
Board-ready reports generated automatically. Monthly performance summaries, season-over-season comparisons, revenue and retention analysis. The kind of reporting that used to require a Treasurer with spreadsheet skills now takes one click.
What’s Coming
Churn Prediction and AI Communications are in active development — club-by-club retention modeling and AI-drafted outreach sequences that launch automatically when risk signals appear.
The Member Splash Feedback Loop
Every feature in Member Splash OS exists because a club asked for it.
Not because a product manager invented it. Because a membership chair at a swim club in Georgia said “I spend three hours every Monday doing this manually and there has to be a better way.” Because a treasurer in Ohio said “I can’t get a clean renewal rate out of this system.” Because a board president in California said “I found out we lost eleven families this season after it was already too late to do anything about it.”
470 clubs. Thousands of board members. Managers. Parents. Staff. Sixteen years of conversations.
Every request, every idea, every pain point — it feeds engineering, product, and AI. Every release makes every club better.
Traditional software works like this: you have a problem, you submit a support ticket, the ticket closes, and that’s the end of it. Maybe it eventually becomes a feature request that sits in a backlog for three years.
Member Splash works differently. Feedback flows directly into the product roadmap. Engineering builds what clubs are actually asking for. Poseidon AI learns from how clubs use what gets built. Every new capability makes the platform more useful for every club on it.
This is the Member Splash Feedback Loop. Sixteen years of compounding. And it’s why no competitor can catch up by simply copying features.
Built With Clubs
Most software companies are built for investors. Quarterly growth metrics. Features that look good in a funding pitch.
That’s not how Member Splash was built.
The roadmap was set by clubs. By volunteer boards asking for better tools. By treasurers who needed cleaner reporting. By membership chairs who needed earlier warning signals. By front desk staff who needed faster check-in.
When you build software with investor money, you’re building for exit. When you build software with club feedback, you’re building for clubs. The difference shows up in every feature, every design decision, every release.
Everything New Inside Member Splash OS
This is the biggest product release in Member Splash’s sixteen-year history. Twelve features shipped, live, and ready for your club.
Member App
The Member Splash app installs directly from your members’ browsers — no App Store, no download friction. Works on iPhone, Android, tablet, and desktop. Members get a home screen icon, push notifications, and a full-featured club experience from a single tap. Check in at the gate, book a court, pay at concessions, register for events — everything in one place. Setup included with onboarding. Members install it on day one.
Splash Cards
Splash Cards are digital prepaid accounts members load from home and spend anywhere at your facility. Multiple cards per family. Balance visible anytime in the app. Fully integrated with your point of sale — no separate system, no reconciliation. Members stop fumbling for cash or cards. Staff stop handling end-of-day cash discrepancies.
Lessons & Clinics
Members register and pay for swim lessons and clinics directly from the app. Rosters built automatically. Reminders sent automatically. Scheduling managed in Member Splash alongside everything else your club runs. No third-party booking system. No manual enrollment spreadsheets. Lesson revenue flows into your reporting alongside all other club revenue.
Paid Reservations
Charge for court time, lane rentals, or any facility. Payment collected upfront at booking — no chasing fees after the fact. Capacity limits enforced automatically. Booking conflicts prevented in real time. Revenue from paid reservations tracked and reported alongside membership dues and other income streams.
Day Use Passes
Sell single-day facility access for guests online or at the gate. Custom pricing tiers, waiver capture, and capacity limits built in. No manual gate logs. No paper waivers. Revenue and attendance tracked automatically. Works for guest days, community events, open swim — any single-day access scenario your club needs.
AI Availability Builder
Describe your facility’s availability rules in plain language and Poseidon AI builds your schedule. Courts, lanes, pools — any facility. Type or speak your rules. The AI builds it, you review and adjust, then publish. Configuration that previously required hours of manual entry now takes minutes.
Staff Scheduler
Build staff schedules, manage time-off requests, and track hours — all in one place. Employees clock in and out from their phones. Managers approve time-off with one tap. Hours and pay summaries export directly for payroll. No separate scheduling tool, no shared spreadsheet, no manual timesheet collection.
Custom Announcements
Greet members with a message the moment they log in. Swim meet reminders, rule changes, pool closures, upcoming events — fully branded, fully scheduled, acknowledged and dismissed by members. Set start and end dates. Add images, text, and links. No message gets missed.
Push Notifications
Reach every member on their lock screen. Closures, weather, registration deadlines, event reminders — delivered like a text message, without the cost. Send to all members or target specific groups. Opt-in managed through the app. Delivery confirmed. No more wondering whether your email got opened.
App Self Check-In
Members tap to check in from their phone at the gate. Staff verify instantly on any device. Real-time attendance data flows into Member Splash automatically. Works for all paid members with no additional setup. Faster entry at peak times, zero manual lookups, attendance records that live where the rest of your data lives.
Branded Invoices
Every invoice your club sends carries your logo and your colors. Works across dues, passes, reservations, and lessons. Members see your brand — not ours. Consistent, professional billing that looks like it came from your club.
Geofence Pricing
Set location-based pricing rules that apply automatically based on where a transaction originates. Custom pricing for members who book on-site vs. online, or for specific facilities within your property. Rules enforced automatically — no manual overrides, no staff judgment calls.
Why Clubs Are Implementing Before Next Season
Every club that has made a platform transition in the middle of the season regrets it.
New software during peak operations means staff learning on the job while members are waiting at the gate. It means board members troubleshooting instead of running the club. It means a season that should have been your best becomes your most stressful.
The clubs that get it right implement in the off-season.
Off-season implementation gives you time. Time to configure the platform correctly. Time to migrate your member data without pressure. Time for your board to get comfortable before a single member asks a question. Time for your front desk staff to run through check-in scenarios before opening day.
It gives you a clean launch. Day one of your 2027 season, everything is live. Members install the app before the pool opens. Staff know the check-in flow before the first family arrives. Your board has run a full report before the first board meeting of the year.
The math is simple. Implement now. Launch ready. Run a better season.
Why We’re Opening Only Fifteen Launch Partner Spots
This offer isn’t a promotion. It’s a partnership.
We’re opening fifteen spots because that’s how many clubs we can properly support through onboarding in this window. Not because of an arbitrary limit. Not for scarcity marketing. Because white-glove onboarding requires dedicated time from real people — and we’re not going to stretch that thin.
Launch Partners aren’t just getting a free year of software. They’re getting dedicated migration support. Hands-on configuration. A team that knows your club’s setup before your 2027 season starts.
In exchange, we’re asking Launch Partners to be engaged. To give us real feedback on what’s working and what isn’t. To be part of the product loop that makes Member Splash better for every club that comes after them.
This is how Member Splash has always worked. Not discounts. Partnerships.

How many spots are available?
Fifteen. First come, first served. When spots are gone, the offer closes regardless of the September 30 date.
The Future of Club Management
The pressure on volunteer-run swim and tennis clubs has never been higher.
Members expect a mobile experience. They expect digital cards, push notifications, and online booking — the same frictionless experience they get from every other consumer app in their life. Clubs that can’t deliver it are losing members to clubs that can.
Boards are under increasing scrutiny. Treasurers need cleaner financial visibility. Membership chairs need earlier warning signals. Presidents need to walk into board meetings with data, not guesses.
Volunteer burnout is real. Every hour a volunteer spends reconciling a spreadsheet is an hour they’re not spending on what they volunteered to do. Every manual process that could be automated is a reason the best board members don’t run again.
And the AI moment is here. Not AI as a marketing badge — AI that actually does useful work. That identifies at-risk families before they leave. That drafts the renewal email in your voice. That builds the availability schedule in minutes instead of hours.
This is where Member Splash OS is headed. More automation. Deeper intelligence. Churn prediction. AI-driven communications that launch without anyone pushing a button. A platform that makes the best-run clubs look easy to run.
The clubs that implement now will be ahead. The ones that wait will be catching up.
