Durable advantage, not industries
The industry matters less than whether expertise can become something competitors can't copy.

A live stream of studio notes, source-linked signals, research fragments, and product thinking from Grey Haven.
The industry matters less than whether expertise can become something competitors can't copy.
Why we look for operators who have carried real products to production, not just prototypes.
Open note →Trust comes from legible reasoning and tight context. Notes from building tools for specialists.
Open note →Why we chose PlanetScale's PostgreSQL offering: real performance data, bare metal deployment, and infrastructure that survives cloud outages.
Open note →Your vector database is bleeding money. Pinecone starts at $70/month and scales to $3,000+. Self-hosted Milvus costs $3,000/month in DevOps time. TurboPuffer does the same job for $64/month with zero operational overhead. Here's how.
Open note →LangChain has 100K GitHub stars and everyone uses it. It's also abstraction hell that makes production debugging impossible. Here's why we chose Mirascope's simplicity—and saved 298 hours of maintenance over 3 years.
Open note →While US tech leaders debate AGI timelines, China is building the infrastructure, models, and cultural influence to dominate AI's next decade. Here's what American companies need to understand about the new global AI landscape.
Open note →We needed our portfolio companies to deploy anywhere — AWS, GCP, Azure — without vendor lock-in or operational hell. Control Plane lets small teams go multicloud with 60-80% cost savings and zero dedicated DevOps. Here's how.
Open note →We switched from Next.js to TanStack Start and our velocity increased 40%. Here's why consistency beats novelty, and how our unified tech stack philosophy compounds value across portfolio companies.
Open note →We've released three major open source projects for AI engineering. Here's why giving away our tools makes business sense.
Open note →Building a full-time AI team sounds logical—until you realize you're paying top talent to sit idle 60% of the time. Here's a better model.
Open note →Silicon Valley has 10,000 AI startups competing for the same talent and customers. Meanwhile, the heartland offers lower costs, desperate customers, and zero competition. Here's your playbook for building outside the Bay Area.
Open note →After two years of building AI products through our venture studio model, here's what actually works and what's just VC fairy tales.
Open note →While Silicon Valley chases the next social app, the real AI revolution is happening in manufacturing plants, farms, and construction sites across the heartland. Here's why we're betting on the industries coastal VCs ignore.
Open note →Most AI products stagnate after launch. The ones that dominate? They build data flywheels from day 1. Here's how we turn every user interaction into model improvements across Grey Haven portfolio companies.
Open note →We've built numberous RAG systems across our portfolio. The ones with evals from day 1 reached production 3x faster. Here's our framework for RAG evaluation that prevents the whack-a-mole debugging cycle.
Open note →Tired of AI predictions from people who've never deployed a model? Here's what will actually matter in 2025 from engineers in the trenches.
Open note →Think throwing OCR and ChatGPT at your documents is a strategy? Your document processing pipeline is probably held together with duct tape and delusion.
Open note →Your vector database is not a SQL database with extra math. It's time to stop pretending otherwise before your infrastructure collapses.
Open note →Tired of AI agents that are just ChatGPT in a trench coat? Let's talk about building autonomous systems that actually work in production.
Open note →Your RAG pipeline is hemorrhaging money faster than a venture-backed startup in 2021. Here's why your retrieval augmented generation is actually just expensive random generation.
Open note →While everyone else is writing Medium articles about theoretical AI architectures, we're in the trenches building systems that actually work.
Open note →Finally, enterprise AI that actually works. No more duct tape and optimistic thinking—just solid engineering that ships to production.
