What Sequoia One does
Sequoia One is a Professional Employer Organization (PEO) provider headquartered in Walnut Creek, California, founded in 2003. According to a 2025 industry market review, the company targets startups as its primary customer segment, delivering HR outsourcing, employee benefits administration, payroll processing, and compliance management services aimed at reducing the administrative burden on early-stage companies.
The firm is privately held with no disclosed funding history, parent company, or subsidiaries. It operates with a small team of 1–10 employees and identifies Roy Zerner as principal/head of department. No detailed product portfolio, platform architecture, integrations, or technology stack has been disclosed in the available sources, and no marketing or distribution channels are specified.
The firm's revenue model is not publicly disclosed — pricing, contract structures, and customer economics are unavailable. With no stated customer logos, named accounts, or scale signals beyond the startup segment focus, the operational footprint is effectively uncharacterized beyond its core PEO positioning. Note: a separate firmographic field describes Sequoia One as a consultancy specializing in supply chain planning, product design, executive management, and distribution strategy, which conflicts with the PEO positioning in newer sources; the PEO characterization is treated as the more current and primary based on the 2025 reference.

Sequoia One competitors and assessment
Company assessmentBroad incumbents
- ADP TotalSource: ADP TotalSource is the PEO arm of ADP, the largest payroll services incumbent, offering co-employment, HR, and benefits administration to SMBs. It competes with Sequoia One across most service lines but benefits from ADP's broader scale and brand.
- Paychex PEO: Paychex is a major payroll/HR provider with a PEO offering (Paychex Flex PEO) targeting small and mid-sized businesses. It is comparable as a PEO services provider, though broader in scope and well-established in the market.
Direct peers
- TriNet: TriNet is a PEO specializing in HR solutions for small and mid-sized businesses, including venture-backed startups. It competes head-on with Sequoia One for similar clients and service scope.
- Rippling: Rippling combines HR, payroll, benefits, and IT management in one platform, with a PEO option for US companies. It targets the same startup-to-mid-market segment as Sequoia One with similar bundled employer services.
- Gusto: Gusto provides payroll, benefits, and HR services for startups and small businesses, including PEO-style offerings. It overlaps with Sequoia One in target customer and core service scope.
- Insperity: Insperity is an established PEO providing bundled HR, payroll, benefits, and compliance services to SMBs. It is a direct competitor to Sequoia One in the co-employment/PEO category.
- Justworks: Justworks is a PEO/HR platform purpose-built for small businesses and startups, offering payroll, benefits, compliance, and HR support—directly comparable to Sequoia One's startup-targeted PEO model.
Emerging players
- Zenefits: Zenefits offers HR, benefits, and payroll software plus PEO services aimed at small businesses and startups. It competes in the same bundled employer-services category as Sequoia One with a more product-led approach.
- Oasis (a Paychex company): Oasis is a PEO focused on small businesses and has been acquired by Paychex. It targets a similar customer profile to Sequoia One, providing HR outsourcing and benefits administration.
- Deel: Deel provides Employer of Record (EOR) and global payroll/HR services to startups hiring internationally. While global-first rather than domestic-US PEO like Sequoia One, the EOR/PEO services overlap meaningfully as Deel expands US offerings.
