What Justfix, Inc. does

JustFix, Inc. is a 501(c)(3) nonprofit organization headquartered at 137 Montague Street in Brooklyn, NY, that builds free digital tools and resources to help New York City tenants understand and exercise their housing rights. The organization operates a web-based tenant advocacy platform (app.justfix.org) integrating USPS Certified Mail delivery, SMS text messaging, and bilingual (English/Spanish) interfaces. Its product suite comprises eight interconnected tools: Letter of Complaint (lawyer-approved repair request letters sent via USPS Certified Mail at no cost to the user), WhoOwnsWhat (a building and landlord research database), Rent History Request and Rent History Text Bot (DHCR-integrated rent stabilization records), Good Cause NYC (Good Cause Eviction eligibility screener with rent calculator), Eviction Free NYC (eviction defense resources under Right to Counsel legislation), Area Alerts (weekly neighborhood displacement-risk email monitoring), and Worst Evictors List (an annual public database ranking NYC landlords by eviction filings). Underlying components include integration partnerships with USPS, NY State DHCR, NYC HPD, and NYC 311 for government workflow interoperability, with SendGrid, Email on Acid, and Google Analytics supporting email delivery and engagement analytics, and Netlify hosting the web platform.

The organization pursues a freemium, donation-funded business model with all digital services provided at no cost to tenants; the nonprofit absorbs operational costs including USPS postage. Distribution is direct-to-consumer via self-service web tools, supplemented by community-led growth through partnerships with tenant organizers, housing attorneys, and community organizations. Marketing relies on organic channels (SEO-optimized Learning Center content, email newsletters, and SMS) rather than paid advertising. Customer segments include NYC residential tenants across all housing types (primary), rent stabilized tenants, tenants facing eviction, and tenant organizers. The Privacy Policy explicitly restricts service availability to users within the United States. No funding rounds, parent company, M&A activity, or management team details are disclosed in the available sources.

Others

• ProPublica: Investigative journalism nonprofit that has produced significant housing-related investigations including landlord accountability and tenant displacement reporting. Adjacent to JustFix's Worst Evictors List investigative work in producing public-interest landlord accountability content, though operates through journalism rather than legal tools.

Broad incumbents

• Legal Services NYC: Largest provider of free civil legal services in NYC, offering housing-related legal assistance including eviction defense, landlord disputes, and rent stabilization issues. Directly comparable geography and target population to JustFix, with overlap in addressing housing problems but operating as a traditional legal services organization.
• Urban Resource Institute: NYC social services nonprofit providing housing, domestic violence, and human services programs for vulnerable populations. Comparable in addressing housing stability for vulnerable NYC residents, though primarily a direct-services provider rather than a digital tool builder.
• Legal Aid Society: Major NYC-based legal services nonprofit providing free civil legal services including housing court representation, eviction defense, and tenant advocacy. Overlaps with JustFix's mission of providing free housing-related resources to NYC tenants, though Legal Aid operates as a traditional legal services firm rather than a digital tool builder.
• Community Service Society of New York: NYC-based nonprofit advocating for economic security and housing stability through research, policy, and direct services including benefits access and tenant support. Comparable in targeting low-income NYC residents with housing-related needs and producing data-driven reports, though broader in scope than JustFix's tenant-rights focus.
• National Housing Law Project: National advocacy organization supporting legal services and tenant rights through policy advocacy, impact litigation, and resource production. Comparable in mission (housing justice advocacy) and product type (educational resources, data tools), though operates at national rather than city level and focuses more on legal advocacy than direct service.

Direct peers

• Housing Court Answers: NYC nonprofit providing information and resources about housing court procedures, tenant rights, and navigating the NYC court system for housing disputes. Directly comparable as a NYC-focused tenant advocacy and education resource, though operates primarily through phone-based information services rather than digital self-service tools.
• Lawyers' Committee for Better Housing: Chicago-based nonprofit providing legal services, education, and advocacy for renters facing housing issues, including tenant rights information, legal clinics, and policy advocacy. Most directly comparable to JustFix in mission (tenant rights advocacy) and target population (low-income renters), though operating in a different geography.
• LawHelpNY: Pro Bono Net-operated statewide portal connecting low-income New Yorkers with free legal services including housing-related assistance. Directly comparable as a free digital resource for housing justice and legal self-help in New York, though broader in legal topic scope than JustFix's housing-only focus.

Emerging players

• Eviction Lab: Princeton-based research initiative producing data and visualizations on eviction patterns across the United States, including interactive maps and landlord analysis. Comparable to JustFix's Worst Evictors List and Area Alerts in producing data-driven tenant displacement insights, though positioned as research rather than direct service.
