What HammerLoop does
HammerLoop is a U.S.-only, two-sided online hiring marketplace focused exclusively on the construction trades. The platform connects skilled trade workers — including electricians, plumbers, welders, HVAC technicians, masons, drywallers, roofers, CDL drivers, and 50+ other trades — with contractors and construction employers. Workers create profile "Worker Cards" listing trade, location, hourly rate, certifications, and experience, and can browse and apply to jobs without submitting a resume; employers can post jobs free of charge and browse or filter worker profiles by trade, location, experience, certifications, and availability. The product is delivered through a web platform at hammerloop.com and native iOS and Android applications distributed via the Apple App Store and Google Play Store. Underlying technology is a web and mobile marketplace with location-based matching, in-platform direct messaging, advanced analytics for employers, and Stripe-handled secure payments; the platform was designed and built by 9MILLS, with Twilio for SMS notifications and Google Maps Platform APIs for geolocation.
HammerLoop operates a freemium go-to-market model: workers join free, employers can post jobs free of charge, and a premium subscription tier with a free trial monetizes advanced features such as enhanced analytics and hiring tools. Stripe processes subscription billing and any transactional payments, and Facebook and X social login are supported to reduce onboarding friction. Reported early traction includes approximately 1,000+ active workers, 150–200+ employer companies, 200+ jobs posted, 50+ trades covered, and a 24-hour average time to first applicant, with employer testimonials referencing filling five positions in a single week. The company is registered as Hammerloop LLC in California (Tiburon), was founded in 2025, employs 1–10 people, has not disclosed any venture funding, and operates entirely within the United States.
