Hear from Gustomers

I was expecting a lengthy application process and was shocked at how fast and simple it was to get set up. Pricing is highly competitive, and the investment funds offered are great. Overall, it is a really great product, and excited to keep working with them.

Daniel C.

VP of Finance

Human Interest integrates beautifully with Gusto. We started six months ago, and I haven't had to do anything.

Stanley Chen

President at BerryClean

We're a small business of under ten employees. My main fear was how much paperwork, legalese, etc., would go into managing a 401(k). So, when I found out Human Interest integrated with Gusto, it was a no-brainer. It was super easy onboarding and worked seamlessly with Gusto. It has not added any more work on our side and is working very smoothly.
