Is Human Interest profitable in 2026?

Human Interest does not publicly disclose profitability. Its ARR reportedly crossed $100M in June 2024 per Sacra, and it raised a $100M Series F on October 31, 2025 at a $3B valuation, but no audited profit figures have been released as of mid 2026.

Who owns Human Interest?

Human Interest is privately held and venture backed. Its Series F round, closed October 31, 2025, was led by TPG with Baillie Gifford, BlackRock, Marshall Wace, and Morgan Stanley participating, valuing the company at $3B.

Could AI replace Human Interest's 401(k) service?

AI can automate support and compliance workflows, but Human Interest's subsidiary Human Interest Advisors LLC holds RIA fiduciary status and assumes 3(38)/3(21) legal liability, a licensed role AI cannot assume, per company pricing disclosures as of June 2026.

Who is Human Interest's biggest competitor?

Vestwell and Gusto-owned Guideline are Human Interest's closest rivals. Gusto acquired Guideline in November 2025, and Vestwell acquired the remaining book as Accrue 401k on December 9, 2025, consolidating payroll-bundled distribution against Human Interest.

How much is Human Interest worth in 2026?

Human Interest was valued at $3B after its Series F round of $100M closed October 31, 2025, led by TPG, up from a $1.33B valuation set in its July 2024 Series E led by Marshall Wace and Baillie Gifford.

Human Interest runs 401(k) retirement plans for small and mid-size US businesses.

The call

Human Interest keeps its regulated recordkeeper role while payroll giants bundle rival 401(k) tools like Guideline and Vestwell into the same small-business software Human Interest depends on for distribution.

Human Interest helps small companies set up and manage 401(k) retirement plans, earning recurring fees as the plan administrator. It has real legal protections, its role as a fiduciary and record keeper means big competitors like Fidelity and Vanguard cannot easily copy it, and AI cannot take on legal liability, but rivals like Vestwell and Guideline (owned by Gusto) have the same protections and are bundling retirement plans into payroll software to lock in customers. The biggest question is whether Human Interest can grow fast enough through newer channels, like white-label offerings and financial advisor partnerships, before rivals steal business by making retirement plans part of payroll software that companies already use.

Why

AI pressure: None apparent. AI can automate support and compliance tasks but cannot take on fiduciary liability or the recordkeeper role Human Interest holds. Could AI do the core job? Unlikely.

Bigger players: Gusto's payroll suite bundling Guideline's 401(k), plus Vestwell partnerships with Rippling and ADP. Payroll platforms now offer 401(k) natively through Guideline or Vestwell, cutting the need for a separate provider like Human Interest. Could a giant copy it? No, they are blocked.

What protects it. Its RIA subsidiary and recordkeeper-of-record status put fiduciary liability on Human Interest, a regulatory step rivals must build or partner around.

What would change this call

Gusto, Rippling, or QuickBooks announces an exclusive or expanded payroll-bundled 401(k) partner other than Human Interest. Would show payroll platforms are steering distribution to Vestwell or Guideline instead.
Human Interest discloses confirmed ARR for year-end 2025 versus the ~$200M target. Would show whether growth has decelerated below prior 20%+ YoY pace.
Human Interest files an S-1 or confirms an IPO date. Would show whether the long-signaled 2021 IPO plan is actually materializing.

Key numbers

ARR crossed $100M (2024-06)
Series E $242M at $1.33B valuation (2024-07)
Series F $100M at $3B valuation (2025-10-31)

Named risks

Payroll partner consolidation via Gusto-Guideline and Vestwell-Accrue could cut off shared distribution channels. Severity: high
Financial results remain unaudited and unconfirmed, with ARR beyond June 2024 based only on analyst estimates. Severity: medium
Sub-scale AUM under 0.1% of the $7.3T US 401(k) market limits negotiating leverage versus incumbents. Severity: medium
Headcount contraction from 876 employees in 2023 to 776 in December 2025 signals possible restructuring. Severity: medium
