Checkmate

What Checkmate does

Checkmate, Inc., operating under the DBA Magnum Diego Priority Services, is a privately held Colorado-based legal support services firm founded in 1978 and headquartered in Englewood, Colorado. The company delivers process serving (legal document delivery), skip tracing (locating persons, debtors, witnesses, and assets), court filings, and statewide court research and document retrieval, primarily to law firms, sole practitioners, collection agencies and lending institutions, government agencies, non-profits, and individual consumers across Colorado, with nationwide reach through a pre-screened partner network of process servers.

The company's technology stack centers on the Magnum Diego Priority Services online portal, which provides 24/7 self-serve order placement, document upload, real-time case tracking, and automated invoice generation, supported by a proprietary case tracking program and a mobile application for field agents. Operations are run with in-house paralegals and dedicated (non-subcontractor) process servers carrying Professional Liability/E&O coverage and notaries on staff, which differentiates the firm from typical process serving competitors.

The business model is transactional: clients pay flat-rate per-order fees with no mileage or hidden charges, supplemented by inside sales support via phone and email and a self-serve digital channel. GTM combines direct-to-consumer online ordering with inside sales targeting legal professionals and institutional buyers, supported by professional association memberships across multiple states and a statewide Colorado court-service coverage footprint.
