What Resonance does

Resonance is a SaaS platform purpose-built for the operational coordination of affordable housing relocation programs. Founded in 2019 and headquartered in San Francisco, the company serves public housing authorities (e.g., NYCHA), affordable housing developers (e.g., Related Companies), and relocation service providers (e.g., Kalel Companies) that run complex, multi-year programs under HUD frameworks including RAD, PACT, Section 18, Choice Neighborhoods, HOPE VI, and LIHTC preservation — typically at scales of 500 to 5,000+ households per program.

The platform consists of a connected operational database and a Declarative AI architecture that reasons over structured program data — households, units, timelines, eligibility rules, and voucher constraints — rather than producing generative text. Core modules include Household & Case Management, an AI-powered Relocation & Matching Engine that ranks household-to-unit fits across multiple constraints simultaneously, Scenario Planning & Simulation for evaluating re-sequencing decisions, Compliance & Document Generation (auto-producing URA notices, RAD resident letters, and HUD reports), a Units Module tied to construction readiness, Workflows & Logs for field operations, and a Checklist Countdown System. A Managed Services add-on places Resonance coordinators inside client programs on retainer.

The company makes money through a flat $3,000/month platform license plus volume-based per-active-unit fees of $7–$15 per unit per month (scaling down at 500+ and 1,000+ unit thresholds), a one-time implementation fee scoped to program size, and recurring managed services retainers. Pricing is enterprise-quote-based with no self-serve channel; the entire go-to-market is direct enterprise field and inside sales supported by content marketing (case studies) and four free self-service calculators (ROI, Capacity, Timeline Risk, Compliance Risk Score). The company holds SOC 2 Type II certification and offers a 99.9% uptime SLA, and is led by four co-founders (Liz Letak, Sean Christensen, Sushanth David, Raymon Geis) and a Chief Data Officer.

Includes household tracking, URA compliance documentation, right-to-return eligibility tracking, AI-assisted matching, chain-move and scenario planning, field workflow logs, and multi-stakeholder dashboards.
2. Per Active Unit Usage Fee: Volume-based per-unit fee on top of the platform license. Rate scales down as portfolio grows: $15/unit/month for up to 500 units, $10/unit/month for 500–999 units, $7/unit/month for 1,000+ units. On-hold projects (read-only, no active workflows) billed at $3/unit/month. The bigger the program, the lower the per-unit cost.
3. Implementation Services: One-time setup fee per project covering data migration, workflow configuration, and team onboarding. Scoped to program size. Professional services for managed services retainer — where Resonance coordinators are embedded in the program — operates on a monthly retainer basis.

Products and services

• Resonance Platform A unified SaaS operating system for affordable housing relocation programs (RAD, PACT, Section 18, LIHTC preservation, Choice Neighborhoods, HOPE VI) that combines Household & Case Management, an AI-powered Relocation & Matching Engine, Scenario Planning & Simulation, Compliance & Document Generation, Workflows & Logs, a Units Module, and a Checklist Countdown System into one connected data layer. Targets public housing authorities, affordable housing developers, and relocation service providers managing 500-5,000+ household programs.
• Managed Services Premium add-on service in which dedicated Resonance coordinators are embedded directly into the client's program on a monthly retainer, handling data management, compliance reporting, relocation workflow support, and day-to-day coordination tasks, plus strategic consultation on RAD conversion sequencing, right-to-return tracking, and URA compliance workflows. Designed for programs that want full operational launch from day one without ramp-up lag.
• ROI Calculator Free interactive calculator that models the true cost of manual relocation coordination (coordinator hours lost, household-level overhead) and estimates savings recovery with Resonance across the program lifecycle. Used as a top-of-funnel demand-generation tool for affordable housing program operators.
• Capacity Calculator Free calculator for relocation service providers that models how much coordinator capacity is consumed by manual overhead and estimates how many additional programs the same team could handle with Resonance at current load. Tied to the RSP Capacity Planning solution for portfolio growth.
• Timeline Risk Calculator Free calculator that models construction delay exposure across phases, estimates how many households risk exceeding the 12-month URA permanent relocation benefit threshold, and quantifies financial exposure from unplanned delays. Used by affordable housing developers and relocation service providers evaluating program risk.
• Compliance Risk Score Free self-assessment that scores HUD audit readiness across 8 risk dimensions using the same framework Resonance's team uses when evaluating new programs, producing an estimated finding cost and risk score based on documentation method and tracking gaps.

Approximately 2,000 units across three Manhattan developments (Fulton, Elliot, Chelsea), a 6–7 year phased redevelopment, with NYCHA, Related Companies, and an RSP partner all operating on the same Resonance platform with role-based access. The program demonstrates Resonance's ability to handle NYCHA-scale complexity with full HUD compliance infrastructure.
• Related CompaniescoreStrategic or Co-development PartnerRelated Companies, one of NYC's largest affordable housing developers, uses Resonance alongside NYCHA and an RSP partner for the FEC redevelopment program (~2,000 units, three Manhattan developments, 6–7 year timeline).
