GCast Raises $2M Seed Round to Bring Mobile Gaming to the Big Screen with AI

Paris, France – September 1, 2025 — GCast, the startup turning any mobile game into a shared living-room experience, today announced it is raising a $2 million seed round to accelerate its product development and growth.

With one tap, GCast lets players cast any mobile game from their phone to a TV with imperceptible latency (16ms). Phones transform into controllers, and the TV becomes a social hub enhanced with AI overlays and in-game companions. These companions read gameplay directly from the screen and provide real-time tips, insights, and second-screen features that make solo games smarter and group play more engaging.

“3.2 billion people play on mobile, yet they’re stuck on small screens. Consoles are expensive, and cloud gaming burns cash. GCast unlocks a frictionless way to bring those games to the big screen and make them social again,” said Jules Testard, CEO of GCast and former YC founder of Jam.gg.

The platform operates with a dual flywheel model:

  • B2C freemium app: Free casting for players, with a $3/month upgrade unlocking AI companions, overlays, and couch multiplayer.
  • B2B SDK: Lightweight Unity/Unreal integration for studios, enabling casting, overlays, and new monetization rails without cloud infrastructure.

GCast has already signed its first B2B partner, Piko Interactive, covering a library of 240 retro titles. iOS and Android betas are live, with overlays already working for popular titles such as Magic Arena, Brawl Stars, and Roblox.

The $2M round will be used to:

  • Polish the B2C app and launch virality loops.
  • Expand the AI team and deepen the gaming companion feature set.
  • Build out the SDK marketplace for developers.
  • Drive product-led growth through influencer partnerships, community building, and PR.

The founding team combines proven startup and gaming expertise:

  • Jules Testard (CEO) – previously built Jam.gg to 1M MAU, YC S20 alum.
  • Stéphane Boghossian (CMO) – ex-Lovable ($0 → $75M), founder of ExJewel.
  • Filippo Scognamiglio (CTO) – Android/Unity SDK engineer, built emulator with 1M+ downloads.
  • Théo Le Goff (CPO) – 8 years in game UX/UI, designed Ultra.io ($12M raised).

Why Now:

Gen Z is bringing TVs back for game nights (54% already organize around shared screens). Netflix has added over 100 mobile games with phone-as-controller tests. Apple’s Epic ruling has opened new monetization paths. Meanwhile, PC overlays thrive, but no equivalent exists on mobile—until now.

GCast’s vision is to become the OS for living-room gaming: a seamless bridge between phones, TVs, and headsets, powered by AI companions and second-screen experiences.
