1. Midjourney — $200M with 11 people

The stack

FunctionToolWhy
DistributionDiscord175M users already there. Zero acquisition cost.
PaymentsStripeDirect subscription billing. No sales team needed.
ComputeCustom GPU clusterImage generation at scale. Core IP.
Internal docsSlabLightweight knowledge base. Replaced Notion.
CommunicationDiscord (internal)Same platform as users. Radical simplicity.

Key decision

No CRM. No marketing automation. No analytics beyond Stripe + Discord. David Holz's insight: every tool you don't need is a team you don't need to hire. The product IS the growth engine.

2. Cursor — AI-native development at scale

The stack

FunctionToolWhy
PaymentsStripeSubscription + usage-based billing.
HostingVercelFrontend and API routes. Zero DevOps.
Project managementLinearSpeed-optimized. Built for engineering teams.
DocsNotionPublic changelog + internal wiki.
SupportIntercom + AIAI-first support with human escalation.

Key decision

The product (an AI code editor) means every employee already lives in the tool they're building. Dogfooding at a level most companies can't replicate. The tool IS the culture.

3. ElevenLabs — $500M ARR, 50% B2B, no sales org

The stack

FunctionToolWhy
CloudAWSGPU instances for voice models. Global edge.
PaymentsStripeSelf-serve B2B. Enterprise via Stripe invoicing.
SupportIntercomAI chatbot handles 80%+. Human for enterprise.
Model servingModalServerless GPU. Scale to zero when idle.
AnalyticsMixpanel + MetabaseProduct analytics + internal dashboards.

Key decision

B2B without salespeople. Enterprise customers onboard via Stripe self-serve. The product is so good it sells itself. Support is AI-first by design.

4. Bolt.new / StackBlitz — $2M per employee

The stack

FunctionToolWhy
HostingVercelWebContainer runs in browser. Vercel for deployment.
DatabaseSupabasePostgres with real-time. Open source.
Project mgmtLinearEngineering velocity tracking.
PaymentsStripeSubscription tiers. Usage limits.
AIAnthropic + customClaude for code gen. Custom models for WebContainer.

Key decision

30 people. $20M ARR. Every dollar of revenue funds compute, not headcount. The product itself is AI-mediated development — they literally eat their own dogfood at the architectural level.

5. Lovable — $400M with AI handling lead gen

The stack

FunctionToolWhy
CloudGoogle CloudAI/ML services. Global infrastructure.
DocsNotionCompany-wide wiki. Public docs mirror.
Project mgmtLinearEngineering + product. Speed as default.
SupportIntercom AIAI-native support. Human for complex cases.
CRMAttioAI-powered CRM. Minimal manual entry.

Key decision

146 people for $400M ARR is still 3-5x more efficient than traditional SaaS. The key: AI handles lead gen, onboarding flows, and tier-1 support. Humans focus on edge cases and relationship building.

Patterns across all 5

Stripe is universal. Every company uses it. Self-serve payments eliminate the sales ops function entirely.

Linear or bust. Fast-moving teams standardize on Linear. Speed of project management matters when you have 30 people doing the work of 300.

Intercom with AI. Not just a support tool — the first line of customer interaction. AI handles 70-80% of queries.

No Salesforce. Not one of these companies uses a traditional CRM. When the product is self-serve, CRM is overhead.

No dedicated DevOps. Vercel, Modal, Supabase. Platform-as-a-service eliminates the need for infrastructure teams.
