AI Systems & Product Studio
Build01 engineers production-grade AI products and autonomous infrastructure. AgentOS is our first runtime product—part of an expanding suite built to turn intelligence into verified, dependable execution.
Built for what comes next
Foundation models are advancing rapidly. But turning raw intelligence into dependable business software exposes five systemic failures that no model release can fix alone. Build01 engineers the infrastructure to address each one.
These failures are not model problems. They are infrastructure problems. Build01 builds the systems layer that resolves them — across every product in our suite.
Foundation models have no concept of scope. Without a deterministic supervisor, autonomous agents drift into adjacent tasks, hallucinate sub-goals, and consume unbounded compute—leaving teams with no reliable way to stop, audit, or replay what happened.
Every chat window is a silo. When a session closes, the context, decisions, and architectural rationale disappear. Teams spend hours re-explaining codebase conventions to fresh model instances—a tax that scales poorly and introduces drift across each new run.
Agents confidently report success when tests fail and type contracts break. Without automated, machine-enforced quality gates running directly on the diff, self-reported completion is indistinguishable from hallucinated completion. Production systems cannot tolerate this.
Closed AI platforms bundle execution loops, memory, and runtime into proprietary black boxes. When the vendor changes pricing, deprecates an API, or the model is outcompeted, teams are trapped—workflows, context, and architectural decisions are locked inside a service they don't control.
Enterprise development cycles involve parallel workstreams, cross-team handoffs, and multi-stage pipelines. A single agent operating sequentially through a chat interface cannot coordinate specialist workers, manage dependencies, or respect team boundaries—making true autonomous throughput impossible.
Foundation models are swappable commodities. You shouldn't be locked into a single vendor's closed stack—your execution loops, rules, and workflows must belong to you.
Never rely on self-reported agent completion. Every change must be validated against automated tests, strict contracts, and deterministic quality gates.
Task planning, architectural decisions, and trust records belong inside your version-controlled repository, eliminating prompt bloat and ephemeral context.
Instead of a fragile monolith, Build01 engineers focused, interoperable products that solve distinct bottlenecks across the autonomous lifecycle.
Build01 develops targeted products to power critical stages of the autonomous development and operational lifecycle. Explore how our systems eliminate runtime bottlenecks, verify code deterministically, and scale parallel agent fleets.
Drive coding agents like Claude Code or Codex to implement features, fix bugs, and refactor codebases while keeping execution bounded, observable, and verified in your local repo.
Enforce deterministic contract testing and AST invariant verification on agent-generated diffs before any code merges into production. Replaces self-reported "done" with mathematical verification.
Maintain repo-embedded durable knowledge that captures architecture decisions and run histories across sessions without prompt bloat, token taxes, or proprietary platform lock-in.
Dispatch parallel tasks across specialist agents with strict dependency graphs, bounded execution environments, and automated handoffs. Scale throughput without coordination bottlenecks.
Building dependable AI products requires disciplined systems engineering, not just prompt tweaks.
We pinpoint where autonomous execution breaks down—uncontrolled loops, lost workspace context, or missing verification.
FIND THE FAILUREWe build dedicated, composable tools rather than bloated wrappers, ensuring each system handles one job with deterministic reliability.
ONE SYSTEM, ONE JOBWe build products like AgentOS to run close to your codebase and data—open source, local-first, and free from SaaS lock-in.
LOCAL-FIRSTEvery product undergoes continuous testing against real codebases, strict compiler contracts, and live development workloads.
PROVEN IN PRODUCTIONOur goal at Build01 isn't to add AI hype to existing software. It's to engineer the foundational systems that make autonomous intelligence dependable.
We build the software scaffolding that lets AI agents plan, execute, and verify code deterministically—starting with our open-source runtime, AgentOS.
Foundation models evolve continuously. Build01 products ensure your workflows, workspace memory, and execution rules remain permanent and portable.
We believe your code, task graphs, and trust records belong in your version-controlled repositories, never trapped inside closed vendor platforms.
From individual agent execution with AgentOS to fleet dispatch with Swarm Mesh, Build01 engineers the full stack for dependable autonomy.
Build01 is founded on a clear conviction: foundation models provide the intelligence, but Build01 products provide the systems that make it work.
Build01 is an AI systems company engineering production-grade software and autonomous runtimes.
We believe the opportunity in AI extends beyond individual prompts and closed chat interfaces. It lies in creating modular, high-performance product systems that govern planning, execution, verification, and workspace state.
AgentOS is our first product in production, pioneering loop-engineering for autonomous coders. Backed by an expanding suite of upcoming tools—including EvalOS, Context Spine, and Swarm Mesh—Build01 delivers the infrastructure developers need to orchestrate intelligence reliably.
As we grow our product portfolio, our commitment remains fixed: disciplined software engineering, deterministic verification, and total repository-level control.
