Vector Intelligence / Accord Book: A founder pivoted from building AI apps to creating a self-hosted AI infrastructure l

Accord Book is a self-hosted AI memory and change-control layer that keeps AI-native dev teams aligned with client decisions and project history across every agent, tool, and conversation.

Djordje Puzic, Founder — Dover, Delaware/remote, Belgrade, Serbia — in their own words, from their Builders application. Lightly edited for length; on the record.

The unusual bet

Choosing self-hosted over SaaS was the unusual bet. Every advisor said, "SaaS is simpler to sell." But AI-native agencies won't put client project data on a third-party server they don't control. Self-hosted removes the biggest trust objection at the enterprise level before the sales call even happens. The complexity is real — but so is the moat.

The hardest lesson

I launched under the name "Q" — clean, minimal, memorable — and had to rename six months in when AWS's trademark enforcement made it a liability. The lesson wasn't just "check trademarks early." It was that brand equity you haven't built yet costs nothing to swap; brand equity you've already started building costs everything. Renaming to Accord Book earlier would have been nearly free. Waiting made it expensive in time, SEO, and momentum.

What surprised them

The biggest surprise was realizing that AI-native teams don't fail because the models are too weak — they fail because of the context. There's no shared memory. Every session starts cold, every agent works in isolation, and hard-won client decisions evaporate. The model capability was already there. The infrastructure layer to preserve context and enforce decisions wasn't. I expected to build AI apps. I ended up building AI infrastructure.

The misconception

People assume "AI memory" means chatbot memory — a user preference store or a session history. Accord Book is closer to version control for decisions: structured conflict detection, arbitration workflows, daily digests, and an MCP server that lets AI agents preflight against live project constraints before they act. The category doesn't have a name yet, which makes it harder to explain but easier to own.
