Gusto signs an agreement to acquire Guideline, its most-used retirement product
CEO Joshua Reeves announced an agreement for 401(k) and IRA provider Guideline to join Gusto, subject to final approvals. Guideline was already the most popular retirement product on the Gusto platform, serving more than a million people. TechCrunch later put the purchase at roughly $600 million.
Gusto CEO Joshua Reeves announced on 27 August 2025 that the company had “signed an agreement for Guideline to join Gusto”, subject to final approvals.
Guideline had spent nearly a decade providing 401(k) and IRA plans to more than a million people and was, in Reeves’ words, “already the most popular retirement product on Gusto by far.” The stated rationale is consolidation of the bill: “one modern product to handle payroll, health insurance, HR, time tracking, compliance, and retirement benefits.”
The regulatory driver named in the post: “At least 25 states have already enacted legislation requiring employers to either offer their own retirement plans or enroll employees in a state-funded auto-IRA.”
TechCrunch reported in May 2026 that the acquisition completed for approximately $600 million.
Pricing impact as of the 10 September 2026 capture is nil on the public grid: 401(k) still reads “Pricing varies by 401(k) integration” on Gusto’s add-on list, with no published rate card.
Gusto announces Gusto Solo, a purpose-built plan for one-person S corps covering compliant self-pay, a reasonable-salary calculator and S corp election. The launch post carries no price; Solo surfaces later at $49/mo plus $6/mo per person.
