OpenLazarus describes itself as the AI operating system a company owns⁠1OpenLazarus: the AI operating system your company ownsOpenLazarus. Rather than adding AI to existing subscriptions, it builds one platform per company that holds the records and the communication, with AI teammates working on the same data as staff.

Best for: Companies that want CRM, mail, phones, operations, finance and AI teammates in one system they own, instead of an AI layer on top of rented tools.

Not the right fit for: Teams that only want writing help inside the office apps they already pay for, or that are not ready to move work out of existing tools.

What OpenLazarus is

Each company gets its own instance, designed around how it works. The FAQ lists what it contains: a CRM with contacts, companies and deals, mail, calendar, messages, meetings, tasks and projects, operations and finance modules, reports, and AI teammates⁠2FAQOpenLazarus. The home page adds phone lines, transcripts, invoicing and bookkeeping to the list of modules, each presented as replacing a subscription⁠1OpenLazarus: the AI operating system your company ownsOpenLazarus.

The AI teammates come from a library of ready-made roles, such as a receptionist, a bookkeeper, a purchasing lead and a support agent, or are designed from scratch. Each works inside the company's own system, on the same records staff use, with an inbox, a phone number and limits the company sets⁠3AI employees for your business: ready-made teammatesOpenLazarus. The company decides what a teammate does on its own and what needs approval⁠2FAQOpenLazarus, and OpenLazarus states that every action is logged where staff can see it⁠4OpenLazarus for manufacturingOpenLazarus.

There are two ways in. Small teams design their system in a free AI builder, which needs no account and produces a first design in about ten minutes; teams under 30 then choose a published plan, while companies of 30 or more start with a session with the engineers⁠5Build your OSOpenLazarus. Larger companies can take a yearly AI-Architect engagement, which OpenLazarus always recommends above 100 people⁠6PricingOpenLazarus.

The code and the data belong to the customer. OpenLazarus runs the server when it hosts, with backups, updates and monitoring; the system can be moved to the customer's own cloud, and European companies can run on servers in the EU⁠26FAQOpenLazarusPricingOpenLazarus. Any model can be used through its AI router⁠2FAQOpenLazarus.

Published evidence

• Quick Scan & Go (company-published testimonial). On the OpenLazarus AI-Architects page, the CEO of an 80-store retailer says the team consolidated its data systems into one and deployed AI agents for operations, and attributes 76% profit growth to the work. The figure is the client’s own statement, as published on the OpenLazarus site.⁠7AI implementation partner: systems you ownOpenLazarus

The home page and builder use invented example companies, such as a 380-person freight business, to show the product⁠1OpenLazarus: the AI operating system your company ownsOpenLazarus. They are illustrations, not clients. The client statements on the AI-Architects page are testimonials that OpenLazarus publishes, not independent studies⁠7AI implementation partner: systems you ownOpenLazarus.

Strengths and limits

Strengths

• Holds the records itself (contacts, deals, mail, tasks, invoicing, bookkeeping), so AI teammates act across the business rather than inside one app.
• Each AI teammate has its own inbox and phone number and works within limits the company sets; the company decides what runs automatically and what needs approval.
• Code and data belong to the company, and hosting can be moved to its own cloud; an EU hosting option is offered.
• Prices for plans, hosting and engineering support are published.

Limits

• It replaces tools rather than sitting on top of them, so adoption means moving work, data and habits.
• Customer evidence is limited to testimonials on its own site; there are no independent case studies.
• Engineering support starts at $4,500 a month, which is significant for a small company that wants ongoing changes.
• Its own comparison page ranks it first, so its claims should be tested in a pilot.

Choose another option if: The company lives in Microsoft 365 or Google Workspace and wants AI in the documents and inboxes it already uses. Microsoft 365 Copilot or Gemini for Workspace is the smaller step.

Pricing

Published: Starter $100 a month and Pro $300 a month (each including the same amount in AI credits), managed hosting from $150 a month, engineering support from $4,500 a month and a 5.5% fee on AI credits used through its router.

OpenLazarus also publishes an ROI calculator that estimates savings and costs from a company's own figures. Its outputs are the vendor's model, not measured results⁠8ROI calculatorOpenLazarus.
