The landscape

PropTech fails at the gap between property operations and software roadmaps.

The pattern: a beautiful tenant app that doesn't integrate with the property management system; a smart-building deployment that requires onsite staff to operate; a real-estate marketplace that competes with the brokerage relationships that produce its supply; an investment platform that handles regulated transactions through generic e-signature; and a property-data warehouse with conflicting truth across three different sources. PropTech succeeds when engineering meets the operational reality of property management, not when it ignores it.

Prosigns ships PropTech engineering with the operational reality as primary scope. Property management integrations as primary scope, tenant-experience platforms designed against actual lease workflows, smart-building automation with explicit operations contracts, and the regulatory awareness PropTech actually requires. FORGE handles the platforms; CORTEX handles AI for valuation, lead scoring, and asset analytics; CITADEL handles regulated-transaction workflows.

Where we ship

6 workloads, grounded in this sector.

Specific applications we’ve built and operated for real estate & proptech buyers. Every example below is grounded in a real shipped engagement.

  • 01

    Property management software

    Multi-property platforms with leasing, accounting, maintenance, and tenant communication integrated. Yardi, MRI, AppFolio integration as primary scope, not phase 2.

  • 02

    Tenant experience apps

    Resident-facing apps for payments, maintenance, communication, amenities, and community. Designed against real lease workflows and the operating discipline property management requires.

  • 03

    Smart-building automation

    BMS / IoT integration for HVAC, access control, energy monitoring, and amenity automation. Integration with property management for operational visibility.

  • 04

    Real-estate marketplaces

    Listing platforms, transaction marketplaces, and brokerage tooling with the data-quality discipline real-estate transactions actually require. MLS integration where applicable.

  • 05

    Investment and capital markets

    Real-estate investment platforms, deal-room software, capital-raise tooling, and the regulated-transaction discipline private-market real estate runs on.

  • 06

    AI for valuation and lead scoring

    Automated valuation models (AVMs), lead scoring for residential and commercial brokers, demand forecasting for portfolio managers. With explicit calibration to local market reality.

Quick read

  • - Tenant experience apps: shipped for production teams.
  • - Smart-building automation: shipped for production teams.

How we engage

4 phases, named in the SOW.

Each phase has a deliverable, an owner, and an acceptance criterion specific to real estate & proptech delivery.

  1. 01

    Operational reality assessment

    Discovery in property operations, leasing, and accounting, not in the boardroom. We sit with property managers, leasing agents, and operations teams; audit existing platforms; and identify the operational friction the project has to solve.

  2. 02

    Integration as primary scope

    Yardi, MRI, AppFolio, RealPage, and the long tail of legacy property management systems integrated through documented contracts. We design integrations as primary scope, not phase 2.

  3. 03

    Tenant-respecting design

    Tenant-facing experiences designed against actual lease workflows, fair-housing-aware messaging, and the privacy frame consumer-facing real-estate brands actually have to defend.

  4. 04

    Operating discipline

    Property management rhythms (move-in / move-out, billing cycles, maintenance) reflected in operations cadence. Integration health monitored continuously, with explicit fallback for partner outages.

Practices in real estate & proptech

How each practice plays in this sector.

The capabilities below are scoped to the constraints real estate & proptech procurement actually enforces: compliance, audit, data residency, and vendor risk.

Common questions

Asked before the first call.

  1. 01

    Can you integrate with our existing PMS?

    Yes: Yardi, MRI, AppFolio, RealPage, and most major PMS platforms are in our active engagement portfolio. We integrate as primary scope (not phase 2) with documented interface contracts, and we treat PMS integration as the spine of the architecture.

  2. 02

    Do you do smart buildings?

    Yes: BMS integration (Honeywell, Siemens, Schneider, Johnson Controls), IoT platforms for HVAC and access control, energy monitoring, and the operations tooling that makes building data useful. We tell you when 'smart building' is being used as a marketing term and when there's a real operational case.

  3. 03

    Can you support regulated transactions?

    Yes: capital-markets real-estate transactions, accredited-investor verification, blue-sky law compliance, and the audit trail regulated-transaction platforms require. CITADEL co-pilots regulated-transaction engagements from kickoff.

  4. 04

    What about Fair Housing compliance?

    Fair Housing awareness is part of every tenant- and applicant-facing engagement. Anti-discriminatory design in messaging, lead routing, and AI-driven decision support. We tell you when an AI use case is fair-housing-fragile and design alternatives.

  5. 05

    Do you do brokerage / listing platforms?

    Yes: MLS integration, listing platforms, transaction tooling, and brokerage CRM integration. Salesforce-based and custom-built engagements both in the portfolio.

  6. 06

    What does a real-estate engagement cost?

    Discovery: 3–5 weeks, $40K–$120K. Tenant experience platform: 6–10 months, $400K–$1.2M. Marketplace platform: 6–12 months, $500K–$1.5M. Smart-building IoT: 5–9 months, $300K–$1M. Investment platform: $500K–$2M. Managed Services: $25K–$120K monthly retainer.
