FitLink: Fitness Marketplace Platform
A double-sided marketplace matching fitness seekers with certified local and remote trainers.
Project Snapshot
Executive Summary
FitLink is an on-demand marketplace connecting fitness trainers with clients. Users can discover certified trainers based on reviews and specialization, schedule customized video workouts, pay securely, and track weight/nutrition objectives.
The Challenge
The fitness industry was rapidly shifting to digital, but independent trainers had no unified platform to manage their businesses. Each trainer was juggling separate tools for scheduling, payments, video calls, and client communication. Clients faced the opposite problem — they had to discover trainers through Instagram, book via DMs, and pay through fragmented channels with no buyer protection. Creating a trusted, double-sided marketplace required solving identity verification, real-time video latency, secure payment escrow, and a recommendation system that could match clients with the right trainer based on goals, location, budget, and availability.
The Problem
Independent fitness trainers lacked tools to schedule sessions, collect payments, and manage client workouts. On the other hand, users struggled to find vetted, high-quality trainers tailored to their budgets.
Our Solution
We engineered a React Native mobile application for iOS and Android, paired with a web admin panel. We built a custom video streaming integration, a matching algorithm, and a Stripe Connect payment system to process instant trainer payouts.
Our Approach
We architected FitLink as a two-sided platform with distinct onboarding flows for trainers and clients. Trainers undergo a multi-step verification process including certification validation, identity verification, and a sample video submission. The matching algorithm uses collaborative filtering combined with geolocation data to rank trainers. For video sessions, we implemented a WebRTC-based solution with adaptive bitrate streaming to handle varying network conditions. The payment system uses Stripe Connect with a delayed escrow model that releases funds to trainers 24 hours after session completion.

Frequently Asked Questions
Everything you need to know about the FitLink platform
How does FitLink verify trainer credentials?
Trainers must upload valid certification documents (NASM, ACE, ISSA, etc.), complete a background check, and submit a sample training video. All credentials are manually verified by our compliance team before profiles go live.
What happens if I am not satisfied with a session?
FitLink offers a satisfaction guarantee. If you report an issue within 24 hours of the session, our mediation team reviews the recording and can issue a full or partial refund. Trainers with repeated complaints are removed from the platform.
Can trainers set their own rates and schedule?
Absolutely. Trainers have full control over their pricing, availability calendar, session duration, and service types. FitLink takes a standardized commission only on completed and confirmed sessions.
