Feiliao (Flipchat) \China

Feiliao (marketed internationally as Flipchat) was ByteDance's ambitious attempt to create a next-generation social networking platform that combined short-form video with real-time social interaction. Launched in 2019 at the peak of TikTok's global ascent, Feiliao represented ByteDance's strategic bet on evolving beyond passive content consumption toward active social graph building. The platform integrated TikTok's algorithmic content discovery with WeChat-style messaging, group chat functionality, and ephemeral stories—essentially attempting to merge the engagement mechanics of multiple successful platforms into a unified experience. The 'Why Now' was compelling: ByteDance had unparalleled expertise in recommendation algorithms, massive distribution capabilities through TikTok, and observed that Gen Z users were fragmenting their social lives across multiple apps (TikTok for discovery, Instagram for stories, WhatsApp for messaging). Feiliao aimed to capture this entire behavioral stack within one super-app, leveraging ByteDance's content graph to bootstrap social connections. The platform featured AI-driven friend suggestions based on content preferences, video-first messaging, collaborative content creation tools, and interest-based communities. ByteDance invested $50M+ and deployed significant internal resources, treating this as a strategic priority to own the full social stack and reduce platform risk as governments worldwide scrutinized TikTok.

Pivot Concept

+

Resonance is an AI-native async social platform designed for deep, meaningful connections in the age of information overload. Instead of competing with TikTok/Instagram on engagement metrics, Resonance uses AI to facilitate thoughtful, asynchronous interactions that respect users' attention and time. The core mechanic: users share 'thought threads'—voice memos, video clips, or text—and AI agents help surface relevant responses, summarize conversations, identify collaboration opportunities, and maintain context across time. Think of it as 'Loom meets Discord meets Substack, orchestrated by a personal AI that knows your interests and social context.' The wedge: professionals and creators drowning in Slack/Discord/email who want meaningful collaboration without real-time pressure. The AI handles the cognitive load of maintaining multiple conversation threads, suggesting when to engage, summarizing what you missed, and even drafting contextual responses for review. Unlike incumbents optimizing for daily active users, Resonance optimizes for 'meaningful interactions per week'—quality over quantity. The business model aligns with user wellbeing: paid tiers for advanced AI features, not ads. The technical moat: local-first architecture with on-device AI (Llama 3.1, Mistral) for privacy, federated social graphs for portability, and vector-based context memory that improves with use. Start with a specific niche (YC founders, podcast creators, research collaborators), achieve density, then expand to adjacent communities.

Execution Plan

+

Phase 1

+

WEDGE (Weeks 1-8): Build for 50 YC founders in a single batch. Core feature: AI-summarized async video standups. Each founder records 2-min daily updates; AI generates summaries, identifies collaboration opportunities, and surfaces relevant threads. Use Mux for video, Supabase for data, Replicate for Whisper transcription + GPT-4 summarization. Manual onboarding, white-glove service. Success metric: 40+ founders using it 3+ days/week, NPS >50. Monetization: Free during beta, validate willingness to pay $20/mo through surveys.

Phase 2

+

VALIDATION (Weeks 9-16): Expand to 500 users across 5 cohorts (YC founders, podcast creators, research labs, indie hackers, book clubs). Add core features: threaded conversations with AI context maintenance, smart notifications (AI decides what's urgent), voice-to-text with speaker identification, and 'collaboration signals' (AI suggests who to connect based on complementary interests). Build Stripe integration, launch $15/mo tier with advanced AI features. Instrument everything: retention cohorts, engagement depth, AI accuracy metrics. Success metric: 60%+ W4 retention, 20%+ conversion to paid, $5K MRR.

Phase 3

+

GROWTH (Weeks 17-32): Launch invite-only viral loop—each user gets 5 invites, AI suggests who to invite based on conversation context. Build 'public thought threads' feature where users can share insights publicly (SEO growth). Add integrations: Slack (sync channels to Resonance with AI summaries), Notion (AI extracts action items), Calendar (AI schedules async catch-ups). Launch creator tier ($49/mo) with audience analytics and AI-assisted content repurposing. Expand to 5K users, $50K MRR. Partner with 10 communities (On Deck, South Park Commons, etc.) for cohort-based onboarding.

Phase 4

+

MOAT (Weeks 33-52): Build the features incumbents can't copy: (1) Local-first mode with on-device Llama 3.1 for privacy-sensitive conversations—data never leaves device; (2) Federated social graph using ActivityPub—users can export their network and content; (3) AI memory layer that learns your communication style, interests, and context over time (stored locally, encrypted); (4) 'Attention budget' feature where AI enforces your desired engagement limits; (5) Open API for third-party AI agents to participate in conversations. Launch enterprise tier ($99/user/mo) for remote teams. Build network effects through 'shared AI context'—groups that use Resonance together get better AI suggestions. Target: 25K users, $200K MRR, clear path to $1M ARR.

Monetization Strategy

+
Freemium model aligned with user wellbeing, not attention extraction. FREE tier: 10 async messages/week, basic AI summaries, 2 active threads. CREATOR tier ($15/mo): Unlimited messages, advanced AI features (context memory, collaboration signals, smart notifications), public thought threads, basic analytics. PRO tier ($49/mo): Everything in Creator plus local-first privacy mode, federated social graph, AI-assisted content repurposing, priority support, API access. ENTERPRISE tier ($99/user/mo, min 10 seats): Team workspaces, admin controls, SSO, custom AI training on company knowledge, SLA, dedicated success manager. Revenue projections: Year 1: 25K users, 15% paid conversion, $450K ARR (avg $30/user/yr). Year 2: 150K users, 20% paid conversion, $4.5M ARR. Year 3: 500K users, 25% paid conversion, $18.75M ARR. Additional revenue streams: (1) API access for developers building AI agents ($0.01/message processed), (2) White-label licensing for communities ($5K/mo flat fee), (3) Premium integrations (Notion, Slack, etc.) with rev-share. The key differentiation: we make money when users have meaningful interactions, not when they're addicted. This aligns incentives with user wellbeing and creates a sustainable moat against ad-driven incumbents who can't adopt this model without cannibalizing their core business.
