Della OS:
Smarter Operations. Real Savings.

Your PMS runs the business. Della runs the building.

Most buildings already have great technology. It just doesn't work together, so your team becomes the integration. Follow one building through a move-out, a new lease and a change to the gym hours, and see what happens when the PMS, the building and the people who run it finally work as one. This is Episode 1, and there's much more to come.
Della OS

Standardize every building. Simplify every operation.

Della OS standardizes operations across your portfolio, regardless of the hardware, vendors, or systems in each building. Reduce operating costs, simplify management, and deliver a better resident experience from one platform.

Della OS

The Building
Operating System

Della creates a single operating environment that connects residents, staff, vendors, and building systems into one consistent experience across every property.
Della OS

Della OS transforms building data into operational intelligence, resident services, and measurable business outcomes.

Della OS by the numbers
A result from a live property, and what the platform connects today.

PMS platforms fully integrated:
Yardi, Entrata, RealPage, AppFolio and ResMan.

Net operating income

The Cost of Running a Building Goes Far Beyond Software.

Every property has its own systems, contracts and operating challenges. Della OS connects existing technology, brings overlapping capabilities into one operating environment and reduces the manual work between systems. The result is multiple opportunities to improve NOI, not one universal savings number.

New income

Your building is different. Your opportunity should be calculated accordingly.

For qualifying portfolios

What If Your Building’s Operating System Paid for Itself?

For qualifying portfolios, Della offers access to exclusive programs designed to generate new recurring operating income.

Depending on portfolio size, participation and program eligibility, these opportunities may offset the entire cost of Della OS and potentially generate additional income for property owners.

Less operational expense. More recurring income. One operating platform.

What Della Users Say

We succeed when our properties do.

“Della is the solution to all of your building problems and then some. I am a property manager and have used many different interfaces to manage numerous buildings, and I have never come across something so intelligent. It is extremely easy to use, and the app is so clean and user friendly.”

KM

Property Manager

“If you're like me, you probably never write reviews but still appreciate reading them. Well, Della impressed me so much that I had to make an exception. I'm not kidding. I was actually considering moving, but then Asset Living, our new property manager, brought in Della, and it completely transformed my living experience. My building and my unit feel revitalized in a way I didn’t expect. I've always been frustrated by how incredible buildings often lack basic tech features, like having a luxury car with an analog radio. Finally, someone did something that genuinely makes a difference. Everything just works, and it’s so easy to use. A big thanks to whoever decided to bring Della into our building.”

Justin

Resident

“As a resident whose property recently onboarded Della, I've been thoroughly impressed with the smart features it offers. Being able to control my apartment's temperature and receive instant building updates has made my life incredibly convenient.”

Mike

Resident

“Della is a game changer! The Della Connect dashboard's powerful capabilities have elevated how I manage my properties to a whole new level. Five stars all the way!”

Kaley

Property Manager, Asset Living

“Della is amazing. We had a hard time with all things in our building before Della. Things like getting in touch with the property management was always a struggle. Having multiple apps for everything and struggling to navigate it all was so frustrating. But Della somehow managed to absolutely impress me. It's so easy and smart. Does Della have other buildings? I would seriously only consider living in a building with it. Love love love Della.”

Alison

Resident

“This app is awesome! It's super easy to use and has everything I need to control my house all in one place. I've never had such a convenient way to manage everything in one place. Totally recommend it to anyone!”
