Semantic Applications
Software has been producing the wrong artifact.
Every generation translated intent into code. AI made writing code faster. Closure changes the artifact: a governed product graph the runtime executes across every interface.
Intent in. Product graph out.

AI made writing code faster. The artifact never changed.

The artifact is the product itself — one governed graph, every interface.
Software has always compiled human intent into code.
Closure compiles human intent into products.
Why teams buy
A faster, safer way to deliver software.
Build it once, not three times.
Portal, assistant, and agentic workflow are renders of one graph — not three codebases.
AI inside the application.
Agents operate on the same governed product model as your UI and process — not a chatbot bolted on.
Evolve the model, not the code.
Goals watch live Events and draft evolution proposals — you approve, the graph versions. Change the product without rewriting and redeploying.
Quality is a gate, not a hope.
Drift scans open Issues on the graph — i18n, brand, SEO, ops — and tiered heal fixes what it safely can. Promotion is blocked while high-severity Issues stay open.
Most software isn't unique — it's scaffolding wrapped around a business model. Closure makes the scaffolding part of the runtime. You author the business. Why a product graph? →
How it's organized
Four pillars. One product graph.
Experiences
Portals and apps — rendered from the graph.
Workflows
The journey — Agent Teams as one governed step.
Knowledge
Skills, files, and live data for AI.
Integrations
Seal into systems of record you trust.
Closure doesn't replace your IDE.
It gives your IDE a product model.Your agent learns the paradigm from the runtime, drafts against live schemas, and ships only through the gates every author passes — human or machine.
The Book
We wrote the book on it.
The Last Application traces seventy years of software producing the same artifact — and what happens when the artifact finally changes. Sixteen chapters on why applications rot, why every rewrite fails the same way, and how a governed product graph ends the cycle. Read it free.
Build once. Evolve forever.
Closure is invite-only while we heat toward launch. Request access — we'll approve and send an invite.
