The biggest risk in AI and crypto startups isn’t bad architecture. It’s narrative debt. When your story is murky or mismatched, users can’t onboard, investors can’t pitch you forward and your community can’t retell your value. This piece breaks down the five failure modes behind narrative debt and walks through an engineering-style refactor so founders can ship clarity, trust and traction on purpose.

Keyword search engines like Algolia were designed for precise lookups across structured catalogs. But modern search demands semantic understanding, constraints, personalization, and real-time signals.

Machine learning is centered on creating models that predict accurately. Evaluation metrics offer a way to gauge a model's efficiency, which allows us to refine or even switch algorithms based on performance outcomes.

Decoder-only architecture (GPT) is more efficient to train than encoder-only one (e.g., BERT). This makes it easier to train large GPT models. Large models demonstrate remarkable capabilities for zero- / few-shot learning. This makes decoder-only architecture more suitable for building general purpose language models.

Most AI failures aren't model failures, they're context failures. LLMs are powerful but fundamentally blind to decisions, relationships, history, and tone. The messiest data in any company (email, chat, docs) is where AI struggles most. We spent years building an engine that turns unstructured communication into structured intelligence. This article breaks down what makes this hard, why traditional methods fail, and how a context-first architecture actually works.

AI coding agents excel at building features but fail at production integrations. The issue isn't AI capability—it's lack of integration-specific infrastructure.

AI agents can scaffold UIs, call APIs, and generate data models in seconds. But when it comes to building production-grade integrations, they consistently under-deliver. This isn't an AI problem. It's an infrastructure problem.
