Sourgum

Sourgum is a waste and recycling technology company headquartered in Jersey City, New Jersey. It operates what it calls a "haulsourcing" platform: a digital marketplace and operating layer that connects businesses to a curated network of local haulers for dumpster rentals, recurring commercial pickups, and specialized streams including compost, e-waste and hazardous waste. Customers manage locations, waste streams, invoices, reporting and SLA tracking through a customer portal, with features such as delivery tracking, dispatch photos, automated routing, same-day dumpsters and emergency pickups.

The company positions itself as different from traditional brokers and marketplaces by controlling the end-to-end experience — pricing, scheduling, billing and support — rather than only matching supply and demand. Its platform is built in house and, per company materials, uses proprietary AI algorithms, automated workflows and a custom logistics engine. Haulers in the network are equipped with Sourgum software for operations such as billing and scheduling, offered in free and paid tiers according to one aggregator profile. Sourgum frames landfill diversion and sustainability metrics as core to its model rather than an add-on, arguing that routing and material-handling decisions can lower both cost and waste.

Sourgum serves single-site and multi-location businesses, including construction, real estate, restaurant and retail operators. Named customers cited in its Series A announcement include McDonald's, Toll Brothers and Cushman & Wakefield.

Founding story

The founders, cousins Joe DiNardi-Mack (co-founder and CEO) and Luciano DiNardi, are fourth-generation members of a family in the waste business; their great-grandfather immigrated from Italy and began collecting waste with a horse and buggy in 1897. The family owned and operated collection companies, disposal sites and waste diversion facilities, and both founders worked across industry roles from riding garbage trucks and handling customer calls to running hauling operations and disposal facilities. Observing inefficiencies, opaque pricing, outdated systems and weak sustainability outcomes, they built Sourgum to apply software to the sector; DiNardi-Mack was previously a founding full-stack software engineer at a proptech startup.

Business model

Sourgum sits between commercial waste generators and local haulers, taking service orders directly from customers and fulfilling them through a vetted hauler network while controlling pricing, scheduling, billing and support. It offers both subscription-style recurring commercial service and on-demand temporary dumpster rentals, and it supplies haulers with proprietary operating software; an aggregator profile describes free and paid SaaS tiers for haulers covering functions such as billing, scheduling, service history and messaging.

Company materials describe transparent, predictable pricing to customers with no hidden fees, fuel surcharges or surprise charges, across recurring service subscriptions and on-demand dumpster rentals; a third-party profile additionally references free and paid SaaS tiers sold to haulers.

Traction

Company materials cite more than 14,000 customers across industries, 4 million-plus locations serviced nationwide, and average savings of 50%; the April 2025 Series A release stated the company had grown to serve over 14,000 locations nationwide within three years and cited average customer savings of 20%, alongside a network of 5,000+ vendors.

Latest developments

April 2025: closed a $12.5 million Series A led by Spark Capital with Suffolk Technologies, Founder Collective, 186 Ventures, RiverPark Ventures, BD Investment Management and Broadway Venture Partners, to fund market expansion and the AI-powered platform. The company also unveiled a new brand. A third-party profile cites a launch of its marketplace in the Twin Cities. In September 2025 CEO Joe DiNardi-Mack discussed scaling the platform, supporting local haulers and improving routing and diversion rates on The Environmental Transformation Podcast.
