💵 Business Fit (Scorecard)

⏱ Why Now?

Cloud gaming is expensive, console access is limited, and post-pandemic users crave in-person social play. GCast offers instant, local co-play without infra friction. Netflix, Apple, and Meta are all signaling interest—but lack GCast’s zero-cost distribution and native mobile UX.

✅ Proof & Signals

• SDK deal with Piko (240+ games)
• B2C demo live: Magic Arena overlay
• YC Top 10% prior round
• Reddit + Discord buzz on social/mobile play
• Overlays like Hearthstone’s “TrackoBot” show monetizable demand

🧩 The Market Gap

Cloud gaming failed casual players. Current couch-play is console-gated. Mobile is massive, but single-player. No one’s bridged mobile + TV for multiplayer. GCast makes social gaming frictionless—just cast and play.

🎯 Target Persona

• Mobile-first gamer (13–35)
• Discover via Discord, YouTube, Twitch
• Pain: wants social gaming but no console
• Emotional driver: inclusion, fun with friends
• B2C first, virality-driven, then B2B inbound

💡 Solution

The Idea: Turn your mobile game into a living-room console experience.

How It Works: Cast your game to TV, play with phone as controller. Add real-time overlays and invite friends.

Go-To-Market:

• Launch wedge: Magic Arena, Brawl Stars
• Channels: Discord, Product Hunt, TikTok, gaming YouTubers
• Loops: Invite friends → install → play together

Business Model:

• Freemium (B2C)
• SDK licensing (B2B)
• Referrals & tournaments

Startup Costs: Medium

• Dev-heavy, low infra, light legal (initially)

🆚 Competition & Differentiation

GCast is the first mobile-to-TV gaming platform that lets anyone cast any mobile game to the big screen, play socially with phones as controllers, and enhance gameplay with intelligent overlays. It fills the gap between utility-only casting (e.g., AirDroid), licensed cloud streams (like Xbox Cloud), and limited-party games (like Jackbox).

🕹️ Direct Competitors: Mobile-to-TV Social Gaming

AirConsole

A browser-based platform where smartphones act as controllers for casual multiplayer games on TVs or PCs.

• Strengths: Built-in game catalog + multiplayer support.
• Weakness: Limited game library and browser-only deployment (not mobile SDK)

Jackbox Party Pack

Quiz/party game collection where players join via phone, hosted on PC/console and cast to TV.

• Strengths: Strong brand + social gameplay
• Weakness: Developers must build for console; can't stream any mobile game

🎮 Cloud & Screen Mirroring Tools

AirDroid Cast

Utility for mirroring Android/iOS screens to TVs with two-way audio.

• Pros: Low-latency mirroring
• Cons: Utility focus; no overlay/game features

Generic Screen-Casting Apps

“Cast to TV”, “Miracast”, etc.

• Pros: Very popular, free
• Cons: Basic mirroring with notable latency; no gaming-specific enhancements

☁️ Cloud Gaming Platforms

• Xbox Cloud Gaming, Amazon Luna, Google Stadia, OnLive, Apple Arcade
• Pros: Access to console-grade games anywhere
• Cons: Costly infrastructure, limited to licensed content, requires subscription and remote hardware

Differentiators:

GCast’s Strategic Differentiation

1. Universal Game Access

Cast any mobile game—no licensing or creation required.

2. Game-Centric UX

Mobile-as-controller with low latency (~16ms), splitscreen, overlays & OCR-based enhancements—built for gameplay, not generic mirroring.

3. Dual GTM Engines
• B2C viral via social/mobile gamers
• B2B SDK integrations with dev partners like Piko/Asmodee
4. Lightweight Infra + IP Moat

No heavy streaming infrastructure, open overlays, and patent-pending SDK—hard to replicate horizontally.

⚠️ Execution & Risk

Time to market: Fast

Risk areas: Apple/Google review gatekeeping, scaling cross-device QA

Critical assumptions:

• Mobile users adopt casting
• Devs adopt SDK
• Apple/Google don’t block

💰 Monetization Potential

Rating: High

Why: LTV from hardcore gamers + dev SDK rev share + ad targeting on overlay

🧠 Founder Fit

Perfect. Second-time founder in social gaming with 8M-user track record.
