Single agents hit a ceiling fast. Multi-agent systems are what comes next — and they bring orchestration, governance, and architectural challenges most startups are not ready for. A fractional CTO's field guide.
Read →A practical guide to building retrieval-augmented generation features that actually work — chunking, embeddings, retrieval, re-ranking, evals, and the mistakes I see in almost every first attempt.
Read →The single piece of infrastructure that separates AI features that improve from AI features that drift — what a real eval suite looks like, how to build one, and what to measure.
Read →Why the Model Context Protocol matters for SaaS in 2026, how to expose your product to agents safely, and the specific implementation steps for a seed-stage team.
Read →Why LLM feature costs quietly explode as you scale, the specific decisions that drive the curve, and the handful of optimizations that reliably cut your bill by 50% or more.
Read →The shift from clever prompts to context assembly pipelines — why the 'prompt engineer' role is dissolving, and what replaced it.
Read →A practical decision framework for picking the right LLM for each feature — by cost, latency, quality, privacy, and lock-in — without turning it into a religious debate.
Read →After two years of 'just prompt it,' fine-tuning is quietly winning back ground. Here's when distillation, LoRA, and small specialized models actually beat calling a frontier API.
Read →The architectural patterns that define AI-native SaaS in 2026 — vector stores, semantic caches, tool-use orchestrators, eval infra, and the stack decisions founders get wrong.
Read →A decision framework for founders trying to figure out whether to build, buy, or wrap when adding AI features to a product — with the specific questions that tell you which path fits.
Read →A practical safety baseline for AI features at seed-stage startups — injection defense, PII protection, red-teaming, and audit trails you can implement in a single sprint.
Read →The shift from copilots to agents is restructuring how SaaS gets built, priced, and defended. A fractional CTO's honest read on what that means for founders right now.
