Our Mission

We believe that everyone deserves access to a secure financial future.  In the United States, there’s a huge, quantifiable disparity in the earning and saving potential between those who have access to financial knowledge and those who don’t.  When it comes to 401(k)s, large financial institutions are incentivized to work with corporations who have thousands of employees and millions of dollars in assets so they can maximize profits from their services and fees. As a result, small business owners and their employees end up with the short end of the stick when it comes to retirement savings and financial planning. People shouldn’t have to choose between doing work they’re passionate about and financial security via “big company” benefits.  401(k)s are often only offered at larger corporations that have the HR departments and budgets to sustain them. At Human Interest ®, we focus exclusively on small businesses so that they can have an affordable 401(k) plan that suits their unique needs. We're a Y Combinator-backed company that offers an easy and affordable 401(k) retirement plan for the modern workforce. We're a Series A company disrupting a massive but broken industry through empowering businesses of any size to safeguard the financial futures of their employees -- something that only 14% are able to do today.  We believe that all individuals deserve the opportunity for a secure financial future. We want idealistic and talented people to join our team of doers and builders. Current 401(k) solutions for small businesses are built on legacy software, involve physical paper forms, and are sold with kickbacks to financial advisors whose interests are misaligned with the financial well-being of their clients.  We've built an automated, paperless 401(k) that makes it possible for small businesses to offer a 401(k) benefit to their employees, and we’re proud to be working with over a thousand businesses across the country!

Tech Stack

We work with a range of technologies, including but not limited to: Node TypeScript React Heroku AWS PostgreSQL various legacy systems (but you don’t need to have prior experience with them)

Core Values

We are a diverse set of socially-minded professionals in marketing, engineering, finance, human resources, operations, sales, and more. Each of us has a track record of success in our given fields, and we all feel passionate about using our skills for a worthy cause.  We come from different places, have different backgrounds, and own different experiences, but we all come to work every day knowing we’re working on an important, complex problem together: helping people save for retirement at a critical time when pensions are going extinct and Social Security isn’t enough. We believe that everyone deserves access to a secure financial future, which is why we make it easy to provide a 401(k) to your employees. We're proud of: - helping over 10,000 employees with saving - 98% customer satisfaction rating - serving 100+ industries Diversity and inclusion help us do better as a business, and we deliberately build processes to create a workplace where all are welcome and accepted. We're proactive and purposeful in prioritizing diversity and inclusion internally not only because it's the right thing to do, but also because we believe it's the only way to effectively create products and services that can be truly helpful to all people.
