For Startups
Playbooks, decision frameworks, and case studies written for startups.
LangChain vs. LlamaIndex vs. Raw API: Pick One
Three days into a prototype, every LLM orchestration framework looks the same. Here's how to pick between LangChain, LlamaIndex, and a raw API wrapper based on where you want to own the complexity — not which one had the best quickstart.
Feature Stores Explained: Why Your ML Models Stale Out
Your credit risk model nailed backtesting but production accuracy keeps slipping. The culprit is rarely the model — it's a silent mismatch between how features are computed at training time and at inference. Here's what a feature store actually does about it.
How to Audit an AI Feature Before It Ships to Production
Your AI feature passed internal demos. That's not the same as being ready for real users. Here's the pre-ship audit playbook to either confirm your fear or clear the launch.
Your RAG Pipeline Isn't Failing. Your Chunking Strategy Is.
Most broken RAG pipelines aren't broken at the retrieval layer — they were broken at ingestion, when documents were split without respecting semantic boundaries. Here's why chunking is the silent failure mode no metric catches.
Questions to Ask Before Hiring an AI Development Partner for Healthcare
Every AI vendor claims healthcare experience. Here are 15 specific questions that separate teams who have actually shipped under HIPAA, HL7, and clinical scrutiny from those who built a wellness app and are overstating their credentials.
In-House AI Team vs. AI Development Partner: Pick One
You have 30 days to decide: hire two senior ML engineers or engage an AI development partner for your first core feature. Here's the decision framework that actually matters — and the one axis most founders get wrong.
5 Mistakes We See Teams Make Shipping AI to Thin-File Users
Most thin-file AI lending models don't fail because the architecture is wrong. They fail because the team never audited what happens after the first batch of rejections starts retraining the model. Here are the five failure modes we see most often.
Pinecone vs. Weaviate vs. pgvector: Pick One Without Regret
Every vector database benchmark was run by the vendor being benchmarked. Here's an honest head-to-head of Pinecone, Weaviate, and pgvector for production RAG — based on where your vectors actually need to live, not whose marketing landing page you read last.
Fine-Tune a Prescription NER Model on 500 Labeled Lines
Off-the-shelf medical NER models choke on regional brand names, OCR noise, and mixed-language prescriptions. Here's how to fine-tune your own with roughly 500 labeled lines and a free afternoon.
Your AI Feature Isn't Slow. Your Data Contract Is.
Most production AI features that feel slow aren't bottlenecked by the model. They're bottlenecked by the undocumented assumptions between your product database and the AI layer — and no GPU upgrade fixes that.
How to Cut SaaS Churn With Behavioral Signals Before the Cancel Click
Most B2B SaaS churn is predictable from usage logs 30-45 days before the cancel email arrives. Here's the operator's playbook for catching it — built around the one signal most founders miss: collapsing seat breadth.
Vector Search Is Not Semantic Search (And the Difference Costs You)
Your vector-powered drug lookup demos beautifully but returns clinically wrong matches in production. The gap between vector search and real semantic search is where health-tech features quietly break.
