Most companies that replace an ERP exchange one rented suite for another. OpenLazarus addresses the company that would prefer to stop renting: it describes itself as an AI lab helping established companies become AI-native, and its platform lets them build and own their AI operating system, agents and data⁠1OpenLazarus: the AI operating system your company ownsOpenLazarus.

Best for: Established companies that want to replace the ERP and the tools around it with one AI-native system they own, built by their own team or built for them.

Not the right fit for: Companies that want a packaged suite configured by a large integrator and are content to rent it.

The problem it addresses

An established company typically runs an ERP, a CRM, a mail system, a phone system and a helpdesk, each with its own data and its own subscription. People move information between them by hand. AI tools added on top see one system at a time. OpenLazarus’ description of what keeps companies behind names exactly this: AI tools that are not connected to existing systems, knowledge locked in individual inboxes and documents, and expensive software platforms that hold the company’s data.

What it replaces, and with what

The modules are swapped in on one AI and data layer. According to OpenLazarus, employees sign in to one system in which the features they know are rebuilt, they can address the system by text or email as they would a colleague, and AI agents take the repetitive work under permissions the company sets per action: always, ask or never.

Three design choices carry the argument for an ERP buyer. Model selection runs across several LLMs, which OpenLazarus says lowers token costs by 80% or more. The architecture is headless, so a new model can be adopted without rebuilding the system. And the company owns the code, so it can maintain the system itself, hire any developer or use OpenLazarus engineers. The cost figures are the company’s own claims.

Two ways to work with it

Teams that want to build can use its builder: they describe the business, the software in use and where information is moved by hand, and the builder proposes the applications and agents, with costs. Companies that want it built for them work with OpenLazarus’ team, which starts from code already written and adapts it; the company recommends this route above 100 people.

Strengths and limits

Strengths

• One AI and data layer under every module, so people and agents work from the same records instead of an assistant added to one suite.
• The company owns the code: it can maintain the system itself, hire any developer or use OpenLazarus engineers.
• Model selection across several LLMs and a headless design, so a new model can be adopted without rebuilding the system.
• Two ways in: a builder for teams that want to build it themselves, and a consulting engagement for companies that want it built for them.
• Published prices for hosting, developer support and AI credits.

Limits

• No published, named case study of a completed SAP or other tier-one ERP replacement that we could open.
• Its savings figures (80 to 90% lower IT cost, token costs lower by 80% or more) are the company’s own claims, not independent measurements.
• Consulting engagements are priced per engagement, so the full cost of a build needs a quote.
• A system built around one company’s processes needs that company’s process owners in the room; it is not a product to be installed.

Choose another option if: A regulator, auditor or parent group requires a named packaged ERP, or the company has no appetite to own software. Then a suite such as Dynamics 365 or Odoo is the closer fit.

Pricing

Published: managed hosting from $150 a month, developer support from $4,500 a month including 10 engineering credits, and a 5.5% fee on AI credits. Consulting is priced per engagement.

Questions to ask OpenLazarus

• Which company of our size and sector runs its ledger on the ERP module today, and may we speak to it?
• What will the first process cost to build and run, including AI credits, and what is the ceiling?
• How does the ERP module handle our costing method, tax rules and audit trail?
• What does the handover look like if we later maintain the system with our own developers?
