Software for buildings, listings and the transactions that move them
Real Estate & PropTech
Real estate software has two jobs at once: make a physical asset legible to software, and move a transaction through people who each use a different system. This practice builds property, marketplace, smart-building and closing systems that treat both jobs as one problem.
01Start from where the deal or building stalls
Name where the friction sits.
Real estate buyers usually name one of four frictions. A building that can't report its own status, a marketplace that can't keep up, a closing process stuck in email, or valuation data nobody trusts, each names a different problem. Naming it narrows the route to the fitting practice.
Occupancy, energy and maintenance data sit in disconnected building systems.IoT engineering connects building sensors and systems into one operational feed.
Search, matching and marketplace features have outgrown the platform serving them.Custom engineering rebuilds the marketplace around the search and matching your users actually need.
Title, escrow and closing steps pass through email and disconnected portals.System integration connects title, escrow and closing platforms so a deal stops losing time in handoffs.
Valuation and portfolio data is scattered across systems that disagree.Data modernization builds the governed pipeline behind valuation and portfolio reporting.

Valuation & Portfolio Data
Valuation and portfolio pipelines rebuilt on data teams can trust.
02Physical reality as a design constraint
Built for buildings that don't refresh like software.
Real estate engagements run a delivery process that treats sensor drift, patchy connectivity and third-party title or escrow systems as constraints from day one, not exceptions discovered mid-project. Every release is tested against the messy reality of a live building or an active transaction, not a clean staging environment.
Frame the physical and transactional surface
Sensor coverage, network reliability and the third-party systems a transaction touches are mapped before architecture begins, so an integration gap does not surface mid-deal.
A building and transaction mapDesign for a building, not a data centre
Offline handling, sensor drift and intermittent connectivity are architectural decisions here, because a building's network was never built for uptime guarantees.
Architecture for patchy connectivityValidate closing workflows against real deals
Transaction and closing logic is tested against real title, escrow and brokerage system quirks before launch, not assumed to integrate cleanly.
Workflows tested against real transactionsShip without disrupting an occupied building
Smart-building releases are staged so a sensor or system update never interrupts the people already living or working in the space.

03Services for real estate and PropTech, with the data standards behind each
Find the property service you came for, and the standards it has to speak.
Property buyers arrive looking for a named platform, whether that is a listing engine, a management system or a closing workflow. This ledger pairs each with the deliverable behind it, the listing and building standards it must speak, and the practice that builds it. The four standards that follow decide how data moves between MLS feeds, building systems and closing partners.
| What you need | What we build | Standards and integrations | Where it lives |
|---|---|---|---|
| Property management platform | Tenant, lease, maintenance and portfolio management in one system, with accounting and payment integrations | Yardi and MRI APIs, AppFolio, Open Banking payment rails, GDPR | Custom Software Development |
| Listing and marketplace platform | Search, matching and listing experiences fed by live inventory feeds rather than manual uploads | RESO Web API, RESO Data Dictionary, MLS and IDX feeds, Elasticsearch | Custom Software Development |
| Smart-building integration | Occupancy, energy and maintenance sensors joined into one operational feed a manager can act on | BACnet, Modbus, KNX, Brick Schema, MQTT | IoT Development Services |
| Transaction and closing workflow | Title, escrow, e-signature and buyer communication connected into one tracked, auditable workflow | MISMO data standards, DocuSign and Adobe Sign APIs, ALTA Best Practices, eIDAS | System Integration |
| Valuation and portfolio data pipeline | Governed pipelines joining valuation, occupancy and market data into reporting every stakeholder can trace | RESO Data Dictionary, automated valuation model (AVM) feeds, dbt, Snowflake | Data Modernization |
| Tenant and resident mobile app | Rent payment, maintenance requests, access and notices delivered through one resident app | PCI DSS-scoped payment providers, push notification services, smart-lock APIs, WCAG 2.2 | Mobile App Development |
RESO Web API and Data Dictionary
The RESO transport and field definitions for listing data. Building the marketplace on them means MLS feeds map cleanly instead of through a bespoke parser per board.
MLS and IDX feeds
Multiple listing services publish inventory under IDX display rules that vary by board. The platform enforces each board's display and refresh terms as configuration, not code.
BACnet and Modbus
The building automation protocols HVAC, lighting and metering equipment already speaks. Smart-building integration reads them directly, so no sensor is replaced just to be seen.
GDPR and MISMO
Tenant and buyer records fall under GDPR, and mortgage and closing data follows MISMO structures. Both shape the data model, retention rules and who can see what.
04Evidence and proof
Buildings and transactions that stopped losing time to handoffs.
Real estate proof has to show a physical operation running smoothly, not just a demo. These previews show that standard while written client approvals are collected.

A property maintenance operation that stopped losing dispatch time.
Marlow Estates' field teams managed maintenance requests across a portfolio through disconnected spreadsheets and phone calls. One connected dispatch system cut response time and gave every building the same status view.
- Dispatch response time
- Cut significantly
- Buildings on one view
- Full portfolio
A closing process that stopped living in email.
A residential brokerage moved title, escrow and buyer communication out of email threads into one connected workflow. Deals that used to stall on missing documents now close on schedule.
- Deals delayed by paperwork
- Down
- Closing on scheduled date
- Consistent
They treated our closing timeline like a compliance deadline, and it never slipped.

05Four doors into real estate engineering
Enter through the practice matching the friction.
A disconnected building, a strained marketplace, a manual closing process and untrustworthy valuation data each need a different starting point. The doors below route each situation to its practice, and every one carries the same physical-reality discipline.
- IoT Development
Connect the building's own systems
Occupancy, energy and maintenance sensors joined into one feed a manager can act on.
- Custom Software Development
Rebuild the marketplace or listing platform
Custom engineering for search, matching and listing experiences a growing marketplace actually needs.
- System Integration
Connect closing and title systems
Title, escrow and brokerage platforms integrated so a transaction stops losing days in handoffs.
- Data Modernization
Rebuild valuation and portfolio data
Valuation and portfolio pipelines rebuilt on data a pricing decision can actually rely on.
06Straight answers
Asked before a real estate platform starts.
01Do you build property management platforms?
Yes, covering tenant, maintenance, leasing and portfolio management in one connected system. Property management software here replaces the spreadsheet-and-email pattern most portfolios still run on, without forcing every building onto one rigid workflow.
02Can you connect smart-building and IoT systems?
Regularly, joining occupancy, energy and maintenance sensors from different vendors into one operational feed. The integration is built to tolerate sensor drift and patchy building connectivity rather than assume a clean signal.
03Do you build real estate marketplace or listing platforms?
Yes, including search, matching and marketplace logic built around how buyers and agents actually search, not a generic template. Custom engineering fits the platform to your specific market and inventory.
04How do you handle closing and transaction workflows?
By connecting title, escrow, brokerage and buyer communication into one tracked workflow instead of parallel email threads. Every step has an owner and a status, so a deal stops stalling on a missing document.
05What does real estate software development cost?
It follows the integration and building complexity a scoping engagement maps, since a listing platform and a smart-building rollout carry very different scope. The estimate reflects your actual portfolio, not an industry average.
06Can you support property valuation and portfolio analytics?
Yes, by joining valuation, occupancy and market data into one governed pipeline instead of scattered spreadsheets. Pricing and portfolio decisions then rest on numbers every stakeholder can trace back to source.
07Do you integrate with title and escrow companies?
Through documented interfaces built to each partner's actual system, since title and escrow platforms rarely share a common standard. Each integration is tested against the specific quirks that partner brings.
08Can you take over an existing property or listing platform?
Yes, starting with an assessment of the data, integrations and building systems already in production. The handover includes a stabilisation plan so tenants, agents and buyers see no interruption during the transition.
