Sequoia One Review, an independent broker's honest assessment.

Sequoia One is the PEO built for venture-backed technology and life sciences companies, with the deepest equity-compensation expertise in the industry and strong benefits buying power for startups, and it holds both CPEO certification and ESAC accreditation. It is also the narrowest PEO on our panel: it declines employers outside tech and life sciences regardless of size, prices at a premium tier, and its platform is less polished than Rippling's.

Best for
Venture-backed tech, software, life sciences and biotech companies of 5 to 250 employees, especially in the SF Bay Area and New York, with meaningful equity compensation programs.
Worst for
Blue-collar industries, any company outside the tech and life sciences vertical, and buyers who want low-touch service at a low price.

We've placed clients with Sequoia One across multiple industries and headcounts. The assessment below reflects what actually happens in real engagements, not what the Sequoia One sales deck says happens, not what the affiliate review sites report based on commission spreads, and not what aggregated G2 stars suggest.

Company background: Sequoia One.

Sequoia One was founded in 2001 and is part of Sequoia Consulting Group, a private firm. It does not publicly disclose its worksite employee count, so we cannot place it on the scale that ranks PEOs by headcount, and that is the wrong way to evaluate it anyway. Sequoia One is a vertical specialist: its clients are venture-backed technology, software, life sciences and biotech companies, concentrated in the San Francisco Bay Area and New York tech hubs.

The specialization shows in what it knows. Option grants, ISO and NSO treatment, RSUs, cliff vesting, contractor-to-employee conversions and payroll readiness ahead of an IPO are the problems a venture-backed company brings to its PEO, and Sequoia One's expertise on them is, in our experience, the best in the industry. A generalist PEO can run payroll for a startup; Sequoia One understands the startup's cap table.

Sequoia One holds IRS CPEO certification and ESAC accreditation. CPEO status transfers federal employment tax liability to the PEO and carries the wage base over on a mid-year start; ESAC accreditation puts a bonded financial assurance program behind its obligations. Fewer than seven percent of PEOs hold both, and for a company whose board and investors ask about controls, that stack matters.

Pricing: what to expect.

Sequoia One quotes per client as a PEPM fee and does not publish a rate. Its own profile describes the pricing as a premium tier, and that is consistent with what we see: the price reflects the specialization and the benefits program, and Sequoia One does not compete to be the lowest administrative fee on the page.

Where it earns the premium is benefits and equity administration. Its benefits buying power for startups is rated at the top of our scale, and for a company competing for engineers and scientists against larger employers the quality of the medical and ancillary offer is part of the compensation package. Compare Sequoia One's medical rate table plan by plan against the other quotes, and weigh the equity-comp administration against what you would otherwise pay an outside provider to handle it.

Contracts are annual. Confirm notice and exit terms, and because Sequoia One may not quote a company outside its vertical, confirm your eligibility before you invest time in the comparison.

Strengths: what Sequoia One does well.

Purpose-built for venture-backed tech and life sciences

Sequoia One's whole model is built for one kind of client, and that client gets a PEO that already understands its structure: investor reporting, hiring plans tied to funding rounds, research staff, equity for every hire. We call this the deepest equity-compensation expertise in the PEO industry, and we agree.

Equity compensation handled properly

Option grants, ISO and NSO distinctions, RSUs, cliff vesting, conversions from contractor to employee and the payroll work ahead of an IPO are where generalist PEOs make expensive mistakes. This is the question that most often puts Sequoia One on a shortlist.

Strong benefits buying power for startups

A young company cannot buy competitive benefits on its own census. Sequoia One's benefits program is rated at the top of our scale, and for a startup recruiting against established employers the benefits offer is part of the pitch.

CPEO and ESAC, with tech-hub depth

Both credentials, plus a concentration of clients and expertise in the San Francisco Bay Area and New York. For a company in those hubs, Sequoia One knows the local employment rules and the local talent market.

Considerations: the things to weigh.

We frame these as considerations rather than negatives because most are real trade-offs rather than disqualifying flaws, but they are things we make sure clients understand before signing.

Narrow focus; declines outside the vertical

Sequoia One will decline buyers outside tech and life sciences regardless of size. That is not a weakness for its intended client, but a company in any other industry should not spend time here; it may not even receive a quote.

Premium price tier

Sequoia One prices for its specialization and its benefits program, and it is rarely the lowest administrative fee in a comparison. A startup optimizing on fee alone, or one with little equity compensation to administer, may find a less specialized PEO better value.

A less polished platform than Rippling

The platform is rated well but trails Rippling's. A company that judges a PEO by its software and its IT automation will notice the gap; a company that judges it by how its option grants are handled will not care.

The fit: who should and shouldn't pick Sequoia One.

Good fit for Sequoia One

  • +Venture-backed technology and software companies of 5 to 250 employees
  • +Life sciences and biotech companies with research staff and equity programs
  • +Companies with significant equity compensation or an IPO on the horizon

Bad fit for Sequoia One

  • −Blue-collar industries and higher-risk workers' comp classes
  • −Any company outside the tech and life sciences vertical
  • −Buyers who want low-touch service at the lowest fee
  • −Companies that evaluate a PEO primarily by its software platform

Frequently asked questions Sequoia One.

Is Sequoia One a certified PEO?

Yes. Sequoia One holds IRS CPEO certification and ESAC accreditation, a combination fewer than seven percent of PEOs carry.

What size company is Sequoia One best for?

Sequoia One positions for 5 to 250 employees, with venture-backed technology and life sciences companies the intended client at every point in that range.

Where does Sequoia One operate?

Its client base and expertise are concentrated in the San Francisco Bay Area and New York tech hubs, though it serves venture-backed companies in its vertical more broadly.

Does Sequoia One publish pricing?

No. Sequoia One quotes per client as a PEPM fee, and the pricing sits at a premium tier.

What is the main consideration with Sequoia One?

Its narrow industry focus. Sequoia One declines buyers outside tech and life sciences regardless of size, and it prices at a premium. For its intended client those are features; a company outside those industries will need a different PEO.

How does Sequoia One compare to TriNet?

Both specialize in technology and life sciences and both hold CPEO and ESAC. TriNet is a public national PEO with a premium benefits portfolio and multi-state infrastructure; Sequoia One is a private specialist whose equity-compensation expertise is the deepest in the industry. For a company whose hardest HR problem is its equity program, Sequoia One; for one planning significant multi-state scaling, get both quotes.

Does Sequoia One handle stock options and RSUs?

Yes, and that is its distinctive strength: option grants, ISO and NSO treatment, RSUs, cliff vesting, contractor-to-employee conversions and payroll readiness ahead of an IPO are the problems it is built to handle.
