Should you build or buy Tenant Experience Platform (Commercial Buildings)?
Tenant Experience Platform software for commercial buildings provides a branded mobile app that connects office tenants to building amenities, visitor management, access control, communications, and event programming. Landlords and property managers use it to increase tenant retention and lease conversion by giving occupants a digital interface to their building.

Buy the platform, own the brand. That is what the large owners actually did — ESRT+ is developed by VTS, Brookfield's axiis ships on a Lane package, and Tishman Speyer's ZO started in-house and ended up on vendor infrastructure. Anyone can build the news feed, the events calendar and the amenity booking screen. What stops a custom build is the access layer: issuing and revoking mobile credentials, mapping tenants to users, handling visitors, getting Bluetooth and wallet behavior right, and passing security review against Kastle, Avigilon Alta or Brivo, each with its own exceptions. At $0.05-$0.15 per square foot a million-foot portfolio pays $50,000-$150,000 a year against a $250,000-$400,000 MVP and a permanent app-operations bill. Build only if you are large enough to amortize it across many buildings and you intend the app to be a real data and service layer rather than a tenant newsletter.
Build it, buy it, or bridge?
When building makes sense
A tenant experience platform is, on the surface, a mobile app with notification management, amenity booking, visitor management, and building system integrations, and building one looks straightforward for an organization with mobile development capacity. In practice, the REIT self-builds most often cited turn out to be exactly the opposite: ESRT+ and Brookfield's axiis are both developed on VTS/Lane infrastructure under a landlord's own branding, and Tishman Speyer's in-house ZO app now runs on vendor infrastructure as well. What actually gates a genuine build is not the app shell; it's the access layer: issuing and revoking mobile credentials, mapping tenants to users, handling visitors, and passing security review against Kastle, Avigilon Alta, or Brivo, each with its own integration quirks. The build case only holds for a REIT large enough to amortize that access-layer work across many buildings, with the intent to run the app as a real data and service layer rather than a branded newsletter.
When buying makes sense
Buying earns its keep when branded tenant experience is a genuine leasing differentiator and access-layer engineering isn't something you want to own. HqO and Equiem handle the access control integrations, visitor management, and push notification infrastructure that take real development effort to build, and the market's own biggest examples confirm the pattern: ESRT+, axiis, and Tishman Speyer's ZO are all landlord-branded apps sitting on VTS/Lane infrastructure rather than independent builds. In soft office markets, not every tenant amenity program justifies owning that infrastructure. The engagement data is still valuable; the honest question is whether the difference between owning the pipes and renting a branded front end is worth the access-layer investment in your specific market.
The desk read
A tenant experience platform looks, on the surface, like a mobile app with notification management, amenity booking, visitor management, and building system integrations, technically straightforward for an organization with mobile development capacity. The REITs most often cited for building their own turn out to be running vendor infrastructure underneath: ESRT+ and Brookfield's axiis are VTS/Lane deployments, and Tishman Speyer's ZO, which started in-house, is on vendor infrastructure now too. The vendor consolidation in this space, Lane folding into VTS Rise, tracks the same direction.
HqO and Equiem earn their keep when branded tenant experience is genuinely a leasing differentiator and you don't have the appetite to own the access layer yourself: credential issuance, visitor mapping, security-system integration. In a soft office market, tenant engagement features that seemed necessary in 2022 are increasingly optional. The engagement data layer, who uses which amenities and how often, is genuinely useful for retention and portfolio planning, but owning it means owning the infrastructure underneath it, not just the app shell, and the portfolio has to be large enough to amortize that before the build economics work.

Frequently asked
What is a Tenant Experience Platform for commercial buildings?
The app is the visible part; the harder problem underneath is identity and access, issuing a tenant's mobile credential, revoking it when they move out, and reconciling that against the building's actual access-control hardware.
When does building a Tenant Experience Platform make sense?
Building makes sense only for a REIT large enough to amortize the access-layer engineering (credential issuance, visitor mapping, security-system integration) across many buildings. The branded apps often cited as REIT builds, ESRT+ and axiis, are VTS/Lane deployments underneath, not independent builds, so the actual bar is higher than app development alone suggests.
When does buying a Tenant Experience Platform make sense?
Buying earns its keep when branded tenant experience is a real leasing differentiator and access-layer engineering isn't something you want to own. Vendors handle the credential, visitor, and security-system integrations that take real effort to build, and the market's largest examples of landlord "self-builds": ESRT+, axiis, and Tishman Speyer's ZO, all run on that same vendor infrastructure underneath.
What are the main Tenant Experience Platform vendors?
Representative vendors include HqO, Equiem, Lane (now part of VTS Rise), Sharry, Shareable / BuiltHere. B4 Pro includes the category score and the full vendor list.
Is the tenant experience software market consolidating?
Yes. Lane was acquired into VTS Rise, and Tishman Speyer's own in-house ZO app has since moved onto vendor infrastructure too, the same direction as the market's most-cited landlord builds. Consolidation here has tracked toward fewer, larger platforms rather than toward viable independent builds.
