ERIN

What ERIN does

ERIN Technologies, Inc. is a Pittsburgh-based, venture-backed software company that operates an AI-powered employee referral platform for enterprise and mid-market talent acquisition teams. Founded in 2019 and backed by a $5 million seed round led by Reformation Partners in October 2022 (with a smaller follow-on of approximately $552,343 in September 2024), ERIN has built a three-product portfolio on a shared 'ERIN AI Core' engine: ERIN Refer automates the end-to-end referral lifecycle from text-to-refer via SMS (short code 20000) through eligibility checks, bonus tier administration, and paid-when-ready payroll handoff; ERIN Source is a standalone AI sourcing product that parses job URLs, identifies ideal internal referrers, and maps second-degree professional connections without requiring an ATS integration; and Referral Studio is a free AI assistant that benchmarks bonuses against 12.4M+ real referral payouts and generates branded posters, videos, and policy drafts. The platform supports 30+ certified integrations with major ATS, HRIS, and payroll systems (Workday, iCIMS, Greenhouse, SAP SuccessFactors, Oracle, SmartRecruiters, Lever, UKG, Dayforce, ADP) and is deployed across 100+ countries with SOC 2 and GDPR compliance.

The company monetizes through a tiered subscription model: a free Starter plan covering up to three hires, a Refer plan at $699/month billed annually (targeted at mid-market organizations with up to 2,500 employees), and custom-priced Enterprise contracts with multi-year terms, SSO, dedicated customer success, and custom SLAs. ERIN Source adds a credit-based usage component. Go-to-market combines direct enterprise field sales (25-minute demo, custom proposal), inside sales for mid-market conversion, and product-led growth via the free tier and Referral Studio. Customers span healthcare (Trinity Health, IQVIA, Takeda, Heartland Dental, Sevita, a top-10 health system), retail (Crocs, Tri Star Energy, Verisure), aerospace & defense (RTX), real estate services (JLL), security services (Allied Universal), senior living (Vi Living, Sunrise Senior Living, Methodist Retirement Communities), manufacturing, transportation & logistics, hospitality, and technology (Neuralink). ERIN reports 3M+ employees activated, 5M+ referrals processed, $500M+ in referral bonuses paid, and 4.7/5 on G2 with 16 badges including Employee Referral Leader, Enterprise Leader, and Momentum Leader for Summer 2025. The company serves enterprise and mid-market talent acquisition leaders with a focus on frontline, high-volume, and healthcare-heavy industries where employee referrals drive 35-50% of total hires.
