We designed and built Before You Buy's property platform from scratch, and Erin Living's resident app, building manager portal and admin.
What we build for proptech and real estate
Property products serve many people at once. We design and build for each of them, on the web and on mobile.
Buyer and seller platforms
Search a property, order and pay for reports or services, and come back to a customer portal to download them.
Tools for agents and agencies
Tools that fit an agent's working day and keep the agency's CRM up to date, from inspection follow-ups to buyer leads.
Resident and community apps
Apps for people living in apartment buildings and communities: access, deliveries, notices, amenity bookings and events in one place.
Apps for inspectors and field teams
Mobile apps for the people on site: accept jobs, schedule visits, set availability and upload reports from the phone.
Admin and operations
Back-office systems and building manager portals that replace spreadsheets, email and manual matching for your team.
Integrations
Connections to CRMs, payment providers, messaging and building systems, mapped in discovery so they are in the quote.
Proptech platforms and apps we have built
Real estate and property products our team has designed and built.
Property due diligence
Before You Buy
We designed and built the whole platform from scratch to replace an MVP built offshore: the public website, the customer portal, the admin, BYB Assist for agents and the BYB Inspector app for iOS and Android, followed by maintenance and new features. Before You Buy now describes itself as Australia's largest property due-diligence platform (October 2026).
Residential communities
Erin Living
A resident app for iOS and Android, a building manager portal and a multi-site admin, connected to building access control, parcel lockers and intercoms. Setting up a new resident's access went from days to minutes, and the platform runs in multiple residential developments.
Property inspections
WeView
We turned WeView's manual property inspection service into a designed digital ecosystem: an app for WeViewers, a booking portal for property seekers, a super admin portal and a new brand. The whole ecosystem was designed within six weeks.
And many more, for startups, enterprise and government. See all case studies.

Proptech app development FAQs
What is proptech?
Proptech, short for property technology, is software for buying, selling, renting, managing and living in property. It covers listing and due-diligence platforms, agency CRMs and tools for agents, inspection apps, and apps for residents of apartment buildings and communities.
What proptech and real estate products have you built?
Platforms and apps for buyers, agents, inspectors and residents. For Before You Buy we designed and built the whole property due-diligence platform from scratch: the website, the customer portal, the admin, BYB Assist for agents and the BYB Inspector app. For Erin Living we designed, built and launched a resident app, a building manager portal and an admin. For WeView we designed a property inspection ecosystem across mobile and web.
Can you connect a property platform to real estate CRMs?
Yes. Connecting a platform to agency CRMs, payment providers, messaging and other systems is a normal part of the build, and we map each integration in discovery so it is in the quote. BYB Assist, which we built for Before You Buy, updates the agency CRM after an open for inspection and works with CRMs including Agentbox, Rex and VaultRE.
How much does it cost to build a proptech platform?
It depends on how many sides of the market you serve, the integrations, the platforms and how much already exists. We give every project a fixed quote after a short discovery phase, and a free consultation is enough for a ballpark.
Can you take over our existing app?
Yes. For apps built with tools like Lovable, Cursor or Claude Code, the App Rescue Report tells you what to fix, what to cut and what it costs to launch. For larger products we start with a technical review, then modernise or rebuild only what needs it, with ongoing support and optimisation after launch.
Who owns the code?
You do, once the project is paid in full. The code and documentation are yours, and the apps are published under your own App Store and Google Play accounts.
Do you only work with clients in Sydney and Melbourne?
Our team is based in Sydney and Melbourne, and we work with clients across Australia.
What happens in a free consultation?
A 30-minute call with a senior member of the team. You tell us what you are building, we ask about goals, users, timeline and budget, and we tell you honestly whether we are the right fit. No pitch deck, no obligation. Book a free consultation when it suits you.

1 of 3
Our business has hundreds of suppliers and thousands of customers so we needed a highly robust structure and that’s exactly what was delivered by Julien, Jen and the RL development team.
Rocket Lab’s ability to help define and execute our business through software in a timely fashion, has been a breath of fresh air and a pleasure to work with.
They took what was just an idea in my head and turned it into a product that’s now live on both the App Store and Google Play. From day one they felt like an extension of our team, not an external agency.
