https://eximotech.com Eximo is an AI engineering and advisory firm. We advise teams on where AI is worth the investment, then design and build it: data ingestion and normalization pipelines, retrieval-augmented generation, multi-agent orchestration, and secure agent systems. Legacy .NET modernization available. en Mon, 21 Sep 2026 00:00:00 GMT https://eximotech.com/blog/build-vs-buy-ai-agents https://eximotech.com/blog/build-vs-buy-ai-agents Most teams default to buying, or default to building, and both defaults are wrong some of the time. A concrete framework for when a custom agent earns its cost and when it does not. Mon, 21 Sep 2026 00:00:00 GMT https://eximotech.com/blog/securing-agent-to-agent-communication https://eximotech.com/blog/securing-agent-to-agent-communication As agents start calling other agents and tools across systems, the attack surface stops looking like a normal web app. What actually goes wrong when agents talk to each other, and the defenses that hold up in production.

A plain explanation of what actually makes something an agent, the loop that drives it, and where it fits next to RAG and a simple LLM call. Sat, 12 Sep 2026 00:00:00 GMT https://eximotech.com/blog/how-to-evaluate-a-rag-system https://eximotech.com/blog/how-to-evaluate-a-rag-system You cannot improve a RAG system you cannot measure. How to build an evaluation set, what to score (retrieval and generation separately), and how to keep it honest over time.

Here is what it actually takes to run useful LLM systems inside your own boundary: model hosting, retrieval, and evaluation that never phone home. Sat, 05 Sep 2026 00:00:00 GMT https://eximotech.com/blog/multi-agent-orchestration-in-production https://eximotech.com/blog/multi-agent-orchestration-in-production Multi-agent demos are easy. Multi-agent systems that run reliably need shared memory that is actually safe to share, a single trace across every agent, and clear rules for when control passes. The prompts are the easy part. Wed, 02 Sep 2026 00:00:00 GMT https://eximotech.com/blog/rag-vs-fine-tuning https://eximotech.com/blog/rag-vs-fine-tuning RAG and fine-tuning solve different problems. A decision guide: use RAG for knowledge, fine-tuning for behavior, and start with RAG almost every time. Sat, 22 Aug 2026 00:00:00 GMT https://eximotech.com/blog/document-ingestion-pipeline-for-rag https://eximotech.com/blog/document-ingestion-pipeline-for-rag A production ingestion pipeline is what makes retrieval-augmented generation reliable. Here is the architecture we use: normalize every format into one schema, embed on ingest, and keep the whole run replayable.

A concrete filter for choosing which workflows to hand to an agent.

It is what you pay every year by not doing it: rising maintenance, security exposure, opportunity cost, and a talent premium.
