Background Check Services

Modern API-first background checks for gig, marketplace, and high-volume tech hiring.

Checkr is the modern API-first leader of the background check category, the vendor that built the workflow Uber, DoorDash, Instacart, and most YC tech firms run on. Founded in 2014 by Daniel Yanisse and Jonathan Perichon, Checkr reached an estimated $5B valuation in 2021 and has been NYSE-IPO rumored ever since. The product genuinely changes the workflow: sub-24-hour turnaround on most criminal reports, full self-serve API, modern dispute and adverse-action workflows, configurable adjudication rules, and the cleanest developer experience in the category. The trade-offs are real: a 2020 FCRA class action settled for ~$5M, ongoing AI-screening discrimination concerns through 2024, and pricing that escalates aggressively above the published self-serve tier.

Largest pure-play background check vendor post Sterling acquisition; the new enterprise default.

First Advantage (NASDAQ:FA) is, as of Q1 2025, the largest pure-play background check vendor by revenue, having closed its ~$2.2B acquisition of Sterling Check Corp in March 2025. Founded 2003, IPO 2021, FA was already a top-three enterprise vendor before the Sterling deal; post-acquisition it operates a combined enterprise customer base spanning Fortune 1000, healthcare systems, financial services, and global logistics. The product depth is genuine: 200+ country coverage, deepest ATS integration breadth in the category, mature drug screening, and credentialed verification operations. The risk is integration risk; combining two enterprise-scale operations through 2027 introduces real customer-facing disruption, contract-renegotiation pressure, and platform-consolidation decisions that will favor FA-native technology over legacy Sterling stacks.

Legacy enterprise leader, now operating as part of First Advantage post Q1 2025 acquisition.

Sterling was, until Q1 2025, one of the top two enterprise background check vendors alongside First Advantage. Founded 1975, IPO 2021 (NASDAQ:STER), Sterling went private in June 2024 in a ~$2.2B take-private by Onity Group and Kohlberg & Company, then was acquired by First Advantage in a deal announced February 2024 and closed Q1 2025. Sterling now operates as part of FA, retaining its brand and customer-facing operations through the integration period (expected to extend through 2027). The product remains genuinely strong: deepest legacy ATS integrations (Workday, SuccessFactors), mature international operations, and the most experienced enterprise sales and support team in the category. The risk is consolidation risk; Sterling-stack customers should expect platform-migration decisions, contract-renegotiation pressure, and possible feature deprecations as FA consolidates the combined platform.

Legacy enterprise vendor post 2018 GIS merger; Stone Point PE-owned.

HireRight is one of the three legacy enterprise vendors (alongside Sterling and First Advantage) that defined the category through the 2010s. Founded 1995, HireRight merged with General Information Services (GIS) in 2018 to form a combined business owned by Stone Point Capital. The product remains genuinely strong for legacy enterprise: 200+ country coverage, mature drug screening operations, strong DOT and FMCSA compliance for transportation hiring, and the most experienced healthcare credentialing operations in the category. The risk is PE-shortened innovation budget; under Stone Point ownership, HireRight has prioritized margin expansion over product modernization, and the gap to Checkr on developer experience and modern UX continues to widen.

Cinven-backed enterprise volume specialist with the most consistent contract terms in the category.

Accurate Background is the quietest of the top five enterprise vendors and arguably the most stable. Founded 1997, acquired by Cinven (European PE) in 2019 at an undisclosed valuation, Accurate has built a ~$500M+ ARR business on enterprise volume contracts with Fortune 1000 customers. The product is genuinely strong: national criminal coverage, mature drug screening, deep continuous monitoring, and the most consistent enterprise contract terms in the category (lower-than-average price escalators, reasonable exit clauses, predictable multi-year pricing). The trade-off: innovation velocity is meaningfully below Checkr and the modern vendors; Accurate competes on operational excellence and contract fairness, not product velocity.

Self-serve mid-market vendor, Checkr-acquired 2018; brand maintained but roadmap autonomy thin.

GoodHire was the original modern self-serve background check vendor, founded 2013 by Inflection (the company that became Checkr GoodHire after the parent rebranding). Checkr acquired GoodHire in 2018, and the brand has been maintained as a mid-market self-serve SKU ever since. The product remains genuinely strong for mid-market: best published pricing in the category (packages from $29.99 per report), strong UX for HR teams without API integration needs, and credible employment and education verification operations. The trade-off: roadmap autonomy under Checkr ownership has been thin for several years, and the strategic question is whether GoodHire is a genuine standalone product or simply a Checkr SKU for buyers who do not want to negotiate enterprise terms.

TransUnion-owned SMB and tenant screening with integrated credit data.

Shareable for Hires is the TransUnion-owned background check service, originally built as a SMB screening product and now a credible mid-market option for buyers who want integrated credit data (TransUnion is the source) and self-serve pricing. Founded 2014 within TransUnion, Shareable has remained a TransUnion subsidiary since launch. The product is genuinely strong for SMB and tenant screening: best-in-category credit data (because TransUnion is one of the three US credit bureaus), self-serve pricing with no contract minimums, and clean reports for small business hiring. The trade-off: feature breadth meaningfully thinner than Checkr or GoodHire, and product investment from TransUnion has been steady but not aggressive.

Modern API-first background checks built for marketplace, gig, and contractor workforce screening.

Yardstik is the youngest of the credible modern vendors and the most focused on marketplace and gig workforce screening. Founded 2020, raised a $35M Series A in September 2022 led by Sound Ventures, Yardstik built its product around the specific operational reality of marketplace platforms: high-volume, fast turnaround, configurable adjudication, and API-first integration. Customer roster includes Outschool, Pearl, FlexJobs, and several others. The product is genuinely strong for marketplaces: modern API, configurable adjudication, fast turnaround, and a smaller team that responds quickly to customer feedback. The risk is scale risk; Yardstik is meaningfully smaller than Checkr or the legacy vendors, and ops scaling through high-growth customer onboarding is the open operational question.

UK-built international screening with deep GDPR-native workflows and 180+ country coverage.

Veremark is the UK-built modern vendor most focused on international screening, founded 2018 in London with a deliberately global product approach. The customer roster spans UK, EU, APAC, and remote-first global teams. The product is genuinely strong internationally: 180+ country coverage with native GDPR workflows, multi-language candidate experience, and modern API. Veremark has marketed a blockchain-verified credentials angle since 2020 (Veremark "verified credentials" stored on blockchain), though the substance is more conventional than the marketing suggests; the genuine substance is the GDPR-native compliance posture and international coverage depth. The trade-off: US coverage is meaningfully thinner than Checkr or the US-native vendors.

Canadian-built API-first screening with strong fast-turnaround global checks.

Certn is the Canadian-built modern vendor most focused on fast-turnaround global checks, founded 2016 in Victoria with $90M Series B in 2021 led by Inovia Capital and B Capital. The product is genuinely strong for Canadian and global API-first hiring: native PIPEDA and provincial privacy compliance, fast turnaround on most reports, modern API, and credible coverage across 150+ countries. Certn is the default modern alternative for Canadian-headquartered firms and US firms with meaningful Canadian operations. The trade-off: US coverage is solid but not best-in-class (Checkr remains stronger for US-primary hiring), and feature breadth is thinner than legacy enterprise vendors.
