Eastern Peak builds smart building IoT solutions for landlords and property management companies, and for proptech startups that make connected devices of their own. We write the device firmware as well as the apps, so one team is responsible for everything between the door and the phone.
Our smart building software is designed around the buildings you actually own, older ones included, and the systems already running in them. We build it for startups launching a new IoT smart building product, and for property companies bringing a portfolio of multifamily buildings into one view.
Smart Building Software We Build
Most clients start with one of these and add the rest later, until the whole portfolio runs on one smart building management system.
Access control and smart entry
Residents open the lobby and their own door from the phone. Guests and contractors get a key that stops working when the job is done.
Resident apps
One app for door keys and smart apartment technology like thermostats, the same in every building you run. Repair requests go straight to your property management software.
Building management dashboards
Your engineers see HVAC, elevators, water and alarms for every building on one screen, and get an alert when a reading looks wrong.
Sensors and alerts
Leak and temperature sensors catch a burst pipe before it floods the unit below, and open a work order on their own.
Connected devices and firmware
For companies making their own locks or meters. We write the firmware and the app together.
Smart Building Features
Each product starts with the features its users need first, and the rest come later.
- Phone key: opens the lobby and the apartment door
- Guest passes: a code or link that works for a set time
- Package alerts: a notification when a delivery arrives
- In-unit controls: thermostat and lights from the same app
- Repair requests: sent from the app, with photos
- Move-in and move-out access: keys switched on and off with the lease
- Door alerts: a door left open or forced
- Entry history: who opened which door, and when
- Vendor access: keys for contractors that expire after the job
- Portfolio dashboard: every building in one view
- Building reports: alerts and work orders by building
- Roles and permissions: separate access for on-site staff and head office
- Device status: offline locks and low batteries flagged
- Self-guided tours: a prospect books a time and gets a key for that slot
- Delivery access: couriers let into the lobby or package room
- Visitor entry: residents see who is at the door and let them in from the phone
- Time limits: every visitor key stops working at the end of its window
Our PropTech Projects
DOORe
Smart lock and video doorbell
DOORe is a smart lock and video doorbell for apartments and homes, connected to the cloud through a small bridge unit. Owners see who is at the door and send family or a cleaner a virtual key that expires. Eastern Peak wrote the firmware for the lock and the bridge, and built the smart home app and the AWS backend.
Goldfarb Connect
Resident app for building access
Goldfarb Properties runs 26 buildings in New York with more than 7,000 apartments. Residents use Goldfarb Connect, the app we built, to open the lobby and their apartment door from the phone and to let visitors in with temporary access. It has been live since October 2024.
SelfTour IQ
Self-guided tours with phone access
SelfTour IQ lets renters view apartments with no agent present. The app books the tour and opens each door on the way, and leasing agents follow up from a web portal. Walk In IQ reports the platform cut vacancy loss by 25% and staffing costs by 35% across Goldfarb Properties’ portfolio.

Our Smart Building Software Development Process
Discovery
We look at what you want to build and the systems it needs to work with, and agree on what the first version should do. You get a scope and a budget range before the build starts.
Design and prototype
Clickable designs of the main screens, so you see how the product works before development starts.
Build and integrate
Development in two-week sprints, with a working version for you to review after each one.
Pilot
A first release to a smaller group of users, and fixes based on what comes up before the wider launch.
Rollout and support
Full rollout, and ongoing development after launch.
A few quick questions show which kind of project yours most likely is.

REVIEWS
We wanted to enhance our shipping solutions by migrating our desktop-based platform and its users to a new web application. Good KPIs met our expectations, generating plans for future collaboration with Eastern Peak.
interview on Clutch
We had a development challenge, as well as a business one. We needed quality people quickly, so we decided to approach Eastern Peak. The results were excellent and we were able to exploit the full potential of the IoT.
interview on Clutch
Eastern Peak assumed responsibility for their results and never tried to deflect it. They stood behind their promises and were very pragmatic. We have received input on app development as well as on our general business model, which helped a lot.
interview on Clutch
We needed to find people who were experienced specifically with startup schedules. Most of the people I’ve worked with had experience of five or six startups, and they’re in their mid-20s. These guys have a good reputation, and I just got very lucky to work with them.
interview on Clutch
They gave me the knowledge, expertise, and experience I needed to launch everything from the beginning and to support it further. They’re like a partner in terms of thinking and creating new concepts, new features, and new ideas.

FAQs on Smart Building Software Development
1. How much does smart building software development cost?
The cost of smart building software development depends on the project. The main factors include the features you need, the devices and systems the software has to work with, how many locations it serves, and whether it includes firmware for your own device.
2. How long does it take to build?
A pilot in one building usually goes live within a few months. Hardware lead times and access to the building’s existing systems set the pace, so we start on both in the first week.
3. Can you work with the locks and building systems we already have?
Yes, as long as the equipment can be connected to, through the manufacturer’s API or a standard building protocol such as BACnet or Modbus. If a device is closed, we can help you choose one that fits the software.
4. How do you keep connected devices secure?
Through the standard practices for connected devices: each device has its own credentials, data travels over encrypted connections, firmware updates are signed so a device only installs trusted code, and staff only get access to the buildings they manage.
