For years, every claims feature at Alan meant building it twice. A year ago, we broke that cycle. Here's what that journey looked like — from expensive first steps to compounding returns, and AI's role in it all 👇. medium.com/alan/universalisa…

Universalisation at Alan: How We Stopped Building Everything Twice

From duplicate codebases to shared flows: how we turned multi-platform pain into compounding gains.

Part 3 of our document processing series is out — how we scaled our pipeline from French insurance docs to new countries and multiple use cases, without rewriting everything. This wraps up the series. Thanks for following along! buff.ly/9cQL4F3

How We Built a Configurable Document Processing Pipeline

We generalized our French insurance document pipeline to handle new countries and multiple use cases.

We think we built the best Python caching library in the world! RAM Redis, atomic writes, distributed invalidation, async refresh, warmup, observability... Dive into this 5-part series, packed with diagrams, code snippets, dashboards, and numbers! buff.ly/QVH9M71

Few-shot examples are only as good as their labels. Ours were hallucinating values from memory. The LLM learned to do the same. Part 2 of the doc processing series: curated datasets, backtesting every change and separating parsing from human knowledge buff.ly/mIQUqa7

Lessons from Running an LLM Document Processing Pipeline in Production

We evolved from text-only to multimodal, built curated reference datasets for RAG and developed an evaluation framework

Ever wondered how Alan reimburses health claims so fast? Spoiler: we automated 70% of document processing. We just dropped the first article of our doc processing series — stay tuned for more on how we're scaling this across other countries and use cases. buff.ly/2Lu7aWD

How we reached 70% document processing automation at Alan

We replaced our classic ML pipeline with a unified LLM-based approach using Markdown Transcription and few-shot RAG extraction

A button color took weeks to ship. Not because it was hard—but because the designer who spotted it couldn't fix it themselves. So we asked: what if everyone could build? #everyonecanbuild

Don't chase leaderboards. There's always a score-latency tradeoff, and LLM providers often hide it. We reproduced Tau-bench to see for ourselves. Here's what we learned: medium.com/alan/benchmarking…

Benchmarking AI Agents: Stop Trusting Headline Scores, Start Measuring Trade-offs

Don’t chase leaderboards. Run the benchmark yourself and map your score–latency–cost frontier to choose models for production.

There are many LLM benchmarks such as MMLU and GSM8k, but they're useless for AI agents. Real agents need to handle database state, tool calling, and multi-turn conversations. Stateful benchmarks show the path forward. New post on agent evaluation 👇 medium.com/alan/benchmarking…

AI agents need stateful benchmarks. Unlike LLMs, agents interact with databases and users. We explore why and how to evaluate them…

Static chatbots couldn't handle complex support tickets about insurance claims. So we built something different with tool calls and the ReAct framework. Our Claim Agent investigates dynamically - just like human agents, but faster. Now automating 30% of tickets it receives.
