Real estate systems often depend on MLS feeds, large search indexes, tenant or transaction data, integrations with old platforms, and rules around how property information can be stored and displayed. That makes previous implementation work more useful than a broad list of technologies on an agency website.
Here are seven companies with published proptech projects worth examining if you're planning a new platform or replacing an existing one.
1. MEV
MEV works on software where the difficult part sits below the UI: data pipelines, search, APIs, migrations, and systems that need to stay available while they're being replaced.
Its work with Hawaii Information Service is a useful example. The MLS platform covers more than 600,000 properties. MEV moved users to the rebuilt system without downtime or data loss and developed a Web API certified for RESO Data Dictionary 2.0.
Search was another engineering problem. The platform needed to support more than 300 filters used by real estate professionals, so the team built a custom search layer with ANTLR4 and Elasticsearch.
For teams working with MLS data, RESO requirements, or a large legacy platform that can't simply be switched off during migration, this is the most relevant part of MEV's track record.
2. Brocoders
Brocoders works across rental, listing, HOA, and property-management products.
One project shows the architecture problem well. Lake, a US vacation-rental platform, had a backend that stopped scaling effectively at around 500 connected properties. Brocoders redesigned it in three months. The resulting system later supported about 40,000 connected properties.
That's the kind of case to examine when your product has found users but the first architecture is becoming the bottleneck.
3. Ascendix Technologies
Ascendix focuses heavily on commercial real estate and builds around Salesforce and Microsoft Dynamics.
Its work includes a CRM implementation and cloud migration for JLL, where adoption reportedly increased roughly sixfold. Ascendix also maintains its own CRE products, including AscendixRE and Ascendix Search.
This makes it relevant when the core engineering question is how to extend an established CRM platform for brokerage workflows rather than build the entire stack from scratch.
4. Taazaa
Legacy modernization is the recurring theme in Taazaa's proptech work.
For Tropicana Properties, the company took over an unstable property application and moved it from an older .NET stack to a current version. According to the published case, manual corrections to tenant payment records dropped from roughly 60 per month to 15–20.
It's a useful example of modernization tied to an operational problem rather than a framework upgrade for its own sake.
5. Inoxoft
Inoxoft's real estate work includes property-management software and AI-assisted operational workflows.
Its maintenance agents can interpret free-text requests and photos, prepare work orders, and route jobs to vendors. In a beta deployment for a 5,000-unit operator, the system reportedly resolved 70% of requests without human input.
For an existing property platform, this points to a different architecture question: where automation can be inserted without rebuilding the core product.
6. Goji Labs
Goji Labs is closer to a product studio than a modernization specialist.
Its proptech portfolio includes Gitcha, a reverse property marketplace, and Pocket, a real estate transaction platform. The work spans user research, UX, product definition, and implementation.
That makes Goji more relevant when the technical scope is still being shaped and the team needs to test workflows before committing to a larger system.
7. OpenSource Technologies
OpenSource Technologies has worked on multi-tenant and white-label property platforms.
Its White Label Storage engagement runs more than 350 self-storage facilities from a shared backend while supporting separate branding, data isolation, and centralized billing.
Teams building one platform for multiple operators should look closely at that model. Tenant boundaries, configuration, billing, and deployment strategy tend to become architectural concerns early.
What to verify before choosing a team
Don't stop at the company portfolio. Ask for the implementation details behind the case study.
For a modernization project, find out how migrations were staged, how rollback worked, and how downtime was handled. For MLS products, ask about RESO, IDX, feed normalization, and search architecture. For multi-tenant SaaS, dig into tenant isolation and configuration management.
Ask what they had to migrate, integrate, certify, or redesign, and what changed after the system went live.
