An honest comparison
URBI vs Building Engines
Building Engines built Prism for a world of separately priced add on modules, a training university, and vendors logging into permissioned web accounts. URBI built one AI native platform for the whole portfolio, with accounting inside it. Here is the real comparison.
URBI puts your whole portfolio in one AI native platform: operations, tenant experience, vendor coordination, and accounting that reconciles itself, CAM included. Building Engines sells an operations platform with a paid AI add on bolted on top, a separate tenant app, and no accounting engine of its own. For commercial buildings, this is not a close call.
Choose URBI if
- You want one platform for the portfolio instead of a core product plus separately priced add on modules
- You want AI that acts: HERO proposes and executes operational work with approval, Arthur answers tenant and resident calls live instead of routing them away
- You want accounting and CAM reconciliation built into the same system as operations, with books pre reconciled at up to 90 percent before close, straight line rent, and estoppel statements ready when you need them
- You want vendors working from an emailed link with no account to create, not a permissioned web login
- You want to be live in weeks on month to month terms, with documentation instead of a certification university
Choose Building Engines if
- Your accounting already runs on Yardi or MRI and you want an operations layer that hands off to it rather than replaces it
- You are comfortable paying separately for an AI add on module on top of the core subscription
- You have staff to put through a 28 course training curriculum and a certification exam
- Your portfolio is already deep in the Prism ecosystem and the switching cost outweighs the gap in what it does

What is the fundamental difference between URBI and Building Engines?
Building Engines is the commercial building operations incumbent, owned by JLL, one of the largest commercial real estate services firms in the world, with over a thousand customers and awards to show for it. That incumbency is real, and it also explains the shape of the product: a core platform, add on modules sold and priced separately, a training university, and a sales process that discloses no pricing until you are already in a quote.
URBI started with the opposite premise: the portfolio is the center, and AI does the heavy lifting inside one system. Operations, tenant experience, vendor coordination, and accounting, CAM reconciliation included, live in one platform that owners, operations teams, and tenants all touch through the same product.
The practical test: Building Engines asks how your team fits into Prism's module structure and which add ons you need to fill the gaps. URBI asks what your portfolio needs and ships it in one system. If you run commercial buildings, you already know which question sounds like less work.
How does URBI's AI compare to Prism AI?
Prism AI is a real product, generally available since August 2025, and it deserves a fair description: it reads documents already stored in Prism, turns operational data into a searchable knowledge base, and answers questions like what issues from last quarter's inspection are still outstanding. That is a genuine capability. It is also sold as a separate add on module on top of the core Prism subscription, and it stops at answering: a person still has to act on what it finds.
Building Engines' only conversational agent, Bengie, is older technology built years before Prism AI, and its own positioning says what it is: a text and messaging chatbot designed to minimize time consuming phone calls. It reduces calls. It does not answer them.
URBI was built AI native. HERO works the problem across a property's records in a loop, shows what it checked, and proposes tickets, work orders, and bookings that a person confirms before anything happens. Arthur, on Premium, answers calls live, over voice, SMS, email, and in-app chat, in the building's own voice, and turns the conversation into a booked action instead of a routed ticket. Ask each vendor to show their AI doing your portfolio's actual work, live, on your scenarios. That is what the demo is for.
What about accounting and CAM reconciliation?
Building Engines has no accounting or CAM reconciliation engine of its own. Its own product pages are direct about this: Prism connects to top accounting platforms like Yardi and MRI rather than replacing them. Prism AI mentions CAM language as an example of the documents it can read and summarize, which is a claim about reading documents, not about performing reconciliation.
URBI's accounting is a full double entry engine, In Beta, built for the AI era: automatic bank reconciliation in three passes with books pre reconciled at up to 90 percent before close, and reporting built for commercial operations specifically, CAM reconciliation, straight line rent, and estoppel statements among more than 40 reports. The work Building Engines hands off to a separate accounting platform, URBI does inside the same system your operations already run on.
It is In Beta, and that is the opportunity: portfolios in the Beta program get the AI accounting stack early and shape where it goes. Sign up through the demo and we will walk your books through it.
What does the tenant experience look like on each?
Building Engines does have a native tenant surface: the Prism for Tenants app, separate from the staff app, plus a web portal and Bengie. But Building Engines' own newsroom describes its HqO partnership as delivering a best of breed combination of building operations and tenant experience, which is Building Engines conceding that the premium tenant experience layer belongs to a partner, not to Prism. The documented scope of that HqO integration is narrow: work order status and visitor registration, nothing broader.
URBI's app is the product, not an add on, included on every plan with unlimited tenants and residents. Amenity and conference room bookings, service requests with photos, package alerts, messaging, visitor and parking access, and documents, all in one app, in one system with operations. Your tenants do not care how many products your vendor stitched together. They care that the one app on their phone does everything, and that is the app URBI ships.
How do vendors work with each platform?
Building Engines' own documentation describes vendor access through web accounts with configurable permissions: authorized users log in to change a work order's status, submit bids, and manage scheduling. That is a real, functioning workflow. It is also an account every vendor has to create and remember.
URBI's vendors answer RFPs and manage work order scheduling and subtasks entirely from a link emailed to them. No account, no password, no login. Amenity closures schedule straight from a ticket. For a portfolio coordinating dozens of vendors across dozens of buildings, removing the login is not a small convenience, it is fewer support calls and faster response every single week.
How long does each take to launch, and what does staff need to learn?
URBI is live in weeks on a fixed playbook: tenant and resident information imports automatically when the portfolio has it ready, staff credentials are provisioned immediately, and residents and tenants get access on launch day. No training program, because none is needed; the product is intuitive and documentation covers the rest. Terms are month to month, so trying URBI costs you nothing but the walkthrough.
Building Engines does not publish an implementation timeline, and larger, more complex portfolios get a professional services led onboarding where Building Engines' team takes a leading role in the migration, which is its own signal about the lift involved. Once live, running Prism is enough of an undertaking that Building Engines operates Prism University: 28 role based courses and a certification assessment for staff. When a vendor builds a university for its own product, believe them: they are telling you what using it is like.
How do the pricing models compare?
URBI prices by building, in three inclusive tiers: a free entry tier, and two flat monthly tiers that include the tenant app, the Kore dashboard, and onboarding, with no setup fee and no per module charges. What you see in the tier is what you get. Exact pricing is custom by volume, and the demo covers it straight.
Building Engines discloses no pricing anywhere, on its own site or on any third party review platform: it is a fully quote gated sales process from the first call. What is published is that Prism AI is sold as a separate add on module on top of the core subscription, so the real total assembles itself module by module after you are already in a sales cycle.
Where URBI is simply the better choice
Strip the incumbency and the JLL branding away and the comparison for commercial portfolios reads one way:
- One platform versus a core product plus paid add on modules: everything in the tier, nothing sold back to you piece by piece
- AI that acts versus AI that answers: HERO proposes and executes, Arthur answers calls live; Prism AI reads documents and Bengie reduces calls
- Accounting and CAM reconciliation built into the same system as operations, pre reconciled at up to 90 percent, versus handed off entirely to Yardi or MRI
- Vendors work from an emailed link with no account, versus a permissioned web login for every vendor on every job
- One tenant app included for the whole portfolio, versus a staff app, a separate tenant app, and a third party HqO layer for the premium experience
- Live in weeks on month to month terms, no certification university, no exit penalty
URBI vs Building Engines: common questions
Is URBI a replacement for Building Engines?
Yes. For commercial portfolios, URBI replaces the parts of Building Engines you actually use: operations, tenant experience, vendor coordination, and, through the Beta program, accounting and CAM reconciliation, in one system instead of a core platform plus separately priced add ons. Book a demo and bring your current Prism workflows; watching them run in URBI is the fastest answer.
Does URBI replace the need for Yardi or MRI the way Building Engines uses them?
Building Engines has no accounting or CAM reconciliation engine of its own and integrates with Yardi or MRI as the system of record. URBI's accounting is a full double entry engine, In Beta, built for commercial operations specifically: CAM reconciliation, straight line rent, and estoppel statements, with books pre reconciled at up to 90 percent before close. Beta portfolios get it early and shape where it goes. Sign up through the demo.
How is URBI's AI different from Prism AI?
Prism AI is a real, generally available feature since August 2025, but it is a document and data question answering layer sold as a separate paid add on, and it stops at answering: a person still acts on what it finds. URBI was built AI native: HERO proposes and executes operational work with approval, and Arthur answers tenant and resident calls live over voice, SMS, email, and chat, not a chatbot designed to reduce calls. Ask both vendors to demo their AI on your portfolio's real scenarios and compare what actually happens.
What does URBI cost compared to Building Engines?
URBI uses three inclusive per building tiers with no setup fee and no per module charges, priced custom by volume; the demo gives you the exact number in one conversation. Building Engines discloses no pricing anywhere and runs a fully quote gated sales process, with AI sold as a separate paid add on module on top of the core subscription.
Do vendors need an account to work with URBI?
No. URBI vendors answer RFPs and manage work order scheduling entirely from a link emailed to them, with no account to create. Building Engines' documented vendor workflow runs through web accounts with configurable permissions instead. For a portfolio coordinating vendors across many buildings, that is the difference between a link they open and a login they have to manage.
How long does switching from Building Engines to URBI take?
URBI launches in weeks on a fixed playbook: automatic tenant and resident data import when your records are ready, staff access immediately, and credentials sent automatically on launch day, with documentation instead of a certification university because the product does not need one. Month to month terms mean there is no lock in on the URBI side of the switch.
