What Build.One does

Build.One GmbH is a German software company headquartered in Freiberg am Neckar that develops the B1 Framework, an AI-native enterprise application development platform. The framework's core architectural pattern uses deterministic JSON blueprints stored in PostgreSQL and versioned through Git as the single source of truth for UI, services, and policies. These blueprints are rendered through a centrally updated Vue 3 evergreen engine, meaning application frontends stay current without app-level migration projects. AI agents operate on blueprints exclusively via policy-bound Model Context Protocol (MCP) operations constrained by database schema validators and CI gates, never editing source code directly. Enterprise controls — SSO/MFA, RBAC/ReBAC, policy-as-code, audit trails, and observability — ship as defaults rather than add-ons. Multi-tenant customization is handled through blueprint overlays and hooks, avoiding code forks.

The company serves large enterprises and government agencies with mission-critical application requirements. Named deployments include the Swiss Federal Office for Social Insurance's disability insurance case management system (1,000+ screens, 1,350+ AI agents, 25M+ documents governed across multiple customized tenants under national compliance), a global CPQ and proposal automation customer (10,000+ SKUs, 15+ languages, 80%+ faster quoting), and enterprise customers Festo, CBRE, and Lucas-Nülle across manufacturing and commercial real estate. ERP applications are reportedly in development on the framework, signaling horizontal expansion.

Build.One employs a hybrid go-to-market combining enterprise field sales for large accounts with a product-led growth developer entry point via GitHub Codespaces, Dev Containers, and an open-source core framework, with platform access gated through a waitlist-based controlled rollout. Revenue is generated through enterprise framework licensing on a recurring subscription basis. The company has raised undisclosed funding from Freigeist Capital (October 2021) and from Interface Capital and s16vc (December 2022). Mike Liewehr is founder and CEO.

Core offering

Build.One develops and sells the B1 Framework, an AI-native enterprise application development framework. The platform combines deterministic blueprint JSON, evergreen Vue 3 UI rendering, and policy-bound MCP AI agents to enable governed generation of mission-critical business applications for enterprise customers.

Product overview

Build.One offers the B1 Framework — an AI-Native Enterprise Framework that provides deterministic blueprints, an evergreen Vue 3 UI renderer, and governed delivery for enterprise teams shipping critical applications using AI agents. The core B1 Framework generates CRUD APIs, OpenAPI specs, and webhooks from blueprints, enforces BetterAuth policies, and enables AI agents to operate on blueprints via policy-bound MCP operations. The framework ships with VS Code dev containers, supports PostgreSQL and Git for blueprint storage, and uses NestJS/Node.js for the logic layer.

Direct peers

• Retool: Retool is a low-code platform for building internal tools and enterprise applications with strong developer ergonomics and AI-assisted development. It overlaps with B1's mission-critical internal-app use cases and shares an enterprise developer-first GTM motion.
• Mendix: Mendix (a Siemens business) provides a low-code enterprise application platform with strong governance and multi-experience development. It targets the same enterprise mission-critical use cases as B1 and offers comparable enterprise controls and integration capabilities.
• OutSystems: OutSystems is a leading low-code enterprise application platform focused on mission-critical, governed app delivery. It competes directly with Build.One's B1 Framework in the same target segment of large enterprises needing AI-assisted, enterprise-grade application development.

Broad incumbents

• ServiceNow App Engine: ServiceNow App Engine allows enterprises to build custom applications on the Now Platform with workflow and governance built in. It overlaps with B1 in enterprise-grade application development for regulated, mission-critical workflows.
• Salesforce Platform: Salesforce Platform enables enterprise application development on the Salesforce ecosystem with governance and extensibility. It is a broad incumbent competing with B1 for enterprise application workloads, particularly within Salesforce-centric enterprises.
• Microsoft Power Apps: Microsoft Power Apps is a low-code application platform embedded in the Microsoft Power Platform with deep enterprise controls, governance, and integrations. It is the dominant broad incumbent competing with B1 in enterprise mission-critical app development.

Emerging players

• LangChain: LangChain is a framework for building LLM-powered applications with agent and orchestration primitives. It is comparable to Build.One's B1 Framework at the AI agent enablement layer via MCP-style integration patterns, though scoped to AI applications.
• Appsmith: Appsmith is an open-source low-code platform for building internal business applications with self-hosting and governance options. It is comparable to Build.One as a newer entrant targeting enterprise internal apps with open-core delivery.
• ToolJet: ToolJet is an open-source low-code platform for building internal tools with database and API integrations. It competes with B1 at the developer-led, blueprint-style application construction layer for enterprise teams.
• Microsoft Semantic Kernel: Microsoft Semantic Kernel is an SDK for integrating AI agents and orchestration into enterprise applications. It is an adjacent AI agent framework comparable to B1's MCP-governed blueprint operations for AI-assisted enterprise development.
