I'm Eric Campbell
I build developer platforms and infrastructure for AI.
Currently building Stack0 — infrastructure for apps and AI agents.
Previously: 4 startups, 4 exits (Google, Ford, Nest, Bird).
Principal Engineer at Zapier. YC W15.
At Stack0, I'm building an AI-native infrastructure platform — email, CDN, video transcoding, AI workflows, and a unified integrations API across 5 languages.
At Zapier, I led the launches of Maker and Forms, and contributed to Tables and Interfaces as Principal Engineer.
At Flow Auctions, I'm building an AI-native auction house management platform with GenAI workflows for lot descriptions, auto-pricing, and marketing.
Track record: founding engineer or CTO at 4 VC-backed startups, all acquired.
- AI-native infrastructure: email, CDN, video, AI workflows
- Unified integrations API, SDKs in 5 languages, usage-based pricing
- AI-native auction house management (Shopify for auction houses)
- GenAI workflows: lot descriptions, auto-pricing, marketing assets
- Led Maker & Forms product launches
- Contributed to Tables & Interfaces products
- Built commuter shuttle platform from 0 to acquisition
- Real-time routing and demand prediction systems
- Mobile-first social networking platform
- Early electric scooter sharing infrastructure
- Home energy monitoring and analytics platform
An all-in-one platform for creatives to manage their content, sell their work to clients, and get paid.
Multi-provider AI pipeline: image generation (Banana/Replicate), video generation (Kling/Runway), audio synthesis. 4c per generation.
Multi-step workflow orchestration: script → parallel image gen → parallel video gen → stitch. DAG execution with fan-out/fan-in.
What I learned building Stack0's SDKs — API design decisions, TypeScript patterns, and the tradeoffs of unified vs service-specific interfaces.
The patterns I've found most impactful in production Next.js apps — eliminating waterfalls, reducing bundle size, and avoiding common RSC mistakes.
How we integrated Claude, GPT-5, and computer vision at Flow Auctions. Prompt management, cost optimization, and why RAG isn't always the answer.
