Description

PlyrVI is a private staff application for volleyball clubs that want a more structured way to develop athletes. The core idea is simple: testing, training, coaching decisions and retesting should not live in separate spreadsheets or in someone’s memory. PlyrVI brings that work into one evidence-based loop: Measure → Assess → Act → Retest Club administrators can manage organizations, teams, staff access, athletes and consent records. Coaches and analysts can record physical tests, training attendance, session workload, volleyball skill assessments, club development standards and coach-owned development actions. The application calculates derived values such as vertical jump, repeated-effort drop-off and session load on the server. It then produces deterministic insights from the evidence already stored. Those insights show what changed, what the comparison is based on and when the evidence is still thin. PlyrVI does not produce a composite talent score. The implemented staff workflow includes: Role-based access for administrators, analysts and assigned-team coaches. Athlete and team management. Staff-recorded youth consent controls. Physical testing and athlete development history. Training attendance and session workload. Volleyball skill assessments. Club-defined development standards. Evidence-backed performance insights. Coach actions, targets, retesting and stored outcomes. Athlete and team performance views. An optional evidence-grounded assistant called Six. PlyrVI is publicly deployed, but it is pre-revenue. It has no paying customers, established user base or completed commercial pilot. The included demonstration organization and athletes are fictional sample data. The repository also contains a local Match Analyzer interface, analyzer source code, bundle importing, court visualization and match-rate calculations. Automated match-video processing is not operational. The required model files are not included, and the current analyzer does not turn a match recording into player tracking, jersey recognition or automated match statistics. That component should be treated as future development, not as a completed feature. The project is best suited to a technically capable buyer who wants an existing sports-technology foundation that can be deployed independently, completed and developed into a commercial volleyball product.

Requirements

Staff use PlyrVI in a current browser on a laptop, tablet, or phone. There is no app-store build. The buyer installs it with Docker, PostgreSQL 16, a Supabase project, DNS, a TLS certificate, and new secrets. The frontend is React 18. The backend is Python 3.12 and FastAPI. The buyer deployment guide is included. The seller's server and accounts are not included.

Changelog

0.1.0, 17 September 2026. First production release of the staff development loop: testing, training, insights, coach actions, and retesting. Match-video reading is not included.

Technology stack · seller-provided

PlyrVI uses a modular monolith architecture: React 18 and TypeScript frontend. Vite build system. Tailwind CSS. TanStack Query and React Router. Three.js, React Three Fiber and Drei for court visualization. Recharts for performance charts. Python 3.12 backend. FastAPI and Pydantic. SQLAlchemy and Alembic. PostgreSQL 16. Supabase authentication for production staff accounts. Docker and Docker Compose. nginx for HTTPS termination and frontend delivery. GitHub Actions for automated linting, tests, builds and deployment. Optional Sentry error monitoring. Optional external AI provider for Six. Production runs as three containers: PostgreSQL, the FastAPI service and nginx serving the built React application.

Post-sale support: Included · Support lasts 14 days after closing and is capped at 10 hours. It covers handover questions, setup clarification, and knowledge transfer.

Migration assistance: Not included

Reason for selling

PlyrVI has reached the point where the foundation is built and the next stage requires a different level of time, technical investment and commercial focus. I would rather transfer the complete project to a capable buyer who can finish the video-analysis work, validate it with clubs and build the commercial operation than leave a serious product sitting unfinished. The buyer is not purchasing an idea on a slide. The application, architecture, development workflow, documentation and public deployment already exist. What remains is the work of completing the unfinished match-video analyzer and taking the product into the market.

What is included in the acquisition

  • Domain namesThe registered domain plyrvi.com transfers at closing through the registrar's normal domain-transfer process. www.plyrvi.com and api.plyrvi.com are addresses on that same domain, not separate registrations. The transfer does not include the current DNS account, the DigitalOcean droplet, or any hosting login.
  • Brand and logoThe original PlyrVI logos, app icons, favicons, and login image transfer with the source snapshot. These files are in frontend/public, and the SVG app icons are in frontend/brand. The PlyrVI name transfers as an unregistered brand. No trademark application has been filed, and no trademark registration is included. The Geist and Geist Mono fonts are not included as owned assets. They remain under the SIL Open Font License 1.1, and those licence notices must stay with the interface.
  • Technical documentation
  • Intellectual property rightsThe sale assigns the seller's original PlyrVI intellectual property in the current source code, documentation, logos, icons, and unregistered rights in the PlyrVI name. The buyer receives a clean snapshot and creates a new repository. The assignment takes effect in the signed purchase agreement. The private Git repository, its commit history, and the GitHub account remain with the seller. No trademark registration exists or transfers. Third-party libraries, including psycopg under LGPL-3.0-only and the Geist fonts under the SIL Open Font License 1.1, remain under their own licences. Trained model files, the production database, personal data, credentials, and the seller's hosting and service accounts are not part of the assigned rights.
  • Complete source code

Ownership and transfer

The buyer receives the seller's original PlyrVI rights in the current source code, documentation, logos, icons, and the unregistered PlyrVI name, plus the plyrvi.com domain through the registrar at closing. The buyer gets a clean snapshot and creates a new repository. The seller keeps the private Git repository, its history, and the GitHub account. No trademark registration exists. Third-party libraries stay under their own licences. The production database, personal data, credentials, hosting and service accounts, and trained model files are excluded.

Handover

The source snapshot and domain transfer are completed at closing. The seller then answers handover questions for 14 days, up to 10 hours total. Support: Support lasts 14 days after closing and is capped at 10 hours. It covers handover questions, setup clarification, and knowledge transfer. It does not include maintenance, new development, a warranty, or finishing the match-video analyzer. Work beyond 10 hours or after 14 days requires a separate written agreement. Handover support is 14 days and 10 hours. It is not a warranty, a maintenance plan, or an obligation to finish the match-video analyzer. The $8,000 figure is an asking price, not an independent valuation. Governing law, payment, warranties, and liability are set in the signed purchase agreement.

External transfers such as domains, store listings, hosting and third-party accounts are arranged directly between buyer and seller after payment.
