Starter 401(k) Enables Competition With State Programs
Kevin Busque and Steven Wu, CEO and CFO of Guideline, on hitting $120M ARR
The key shift is that Guideline can now sell a real employer plan into the same small business accounts that states were funneling into auto IRA programs. Starter K strips out much of the testing and admin work that made a normal 401(k) too hard for restaurants, franchises, and hourly workforces, so Guideline can offer a lower cost plan with payroll integration, employer branding, and a better participant experience than a state default savings program.

The practical unlock is compliance. SECURE 2.0 created starter 401(k) arrangements, and the IRS says the employee deferral cap for these plans remains $6,000 in 2026. That lower ceiling is what makes the product simpler to run for employers that could not handle a full 401(k).
-
State mandates create distribution. In California, employers can satisfy the requirement either by registering with CalSavers or by offering a private retirement plan. That turns every newly mandated small employer into a live sales lead for Guideline instead of a customer the state wins by default.
-
This also changes who Guideline competes with. Historically it sold mainly to white collar SMBs, while Human Interest scaled through broad payroll integrations and incumbents like Fidelity served the large end of the market. Starter K lets Guideline move downmarket into blue collar segments without taking on legacy plan complexity.
Going forward, state auto IRA mandates will keep pushing small employers to make a retirement decision, and starter 401(k) products will convert more of that demand into private plans. That should pull the market away from bare minimum compliance accounts and toward bundled payroll linked retirement products with more room for upsell into HSAs, emergency savings, and higher value plans.
