M1's Commitment to Diversity 

M1 is proud to be an equal opportunity employer. We celebrate different experiences and we're committed to diversity, equity, and inclusion (DEI) at all levels of the company. Women, minorities, veterans, members of the LGBTQIA+ community, and individuals with disabilities are strongly encouraged to apply. With our three DEI task forces (internal education, recruiting, and community involvement) and five Employee Resource Groups (Mental Health, Pride, Black, Latinx, and Women at M1), M1 employees and leaders set aside company time to tackle DEI projects and achieve goals every quarter. 

Our Values 

Our team embodies our ten core principles and if these principles speak to you – we’d love to talk with you.

  • Mission Driven: Life is short – everyone should spend their waking hours on something they find meaningful. We believe improving people’s financial wellness improves lives. It’s a vital and worthy cause.  
  • Extreme Ownership: We think and act like owners. That means we’re responsible for the results to our clients, coworkers, and M1 shareholders. Our focus is on building long-term value, not scoring short-term marks. 
  • Boldness: We want to do things of consequence. Make a difference. Put a dent in the universe. Thinking big inspires results. We’d rather fail at something meaningful than succeed at something trivial. 
  • Bias for Action: Results lag prior efforts – we can’t hope or wait for results. Instead, we believe a good process leads to good outcomes and persistent progress leads to compounding.
  • Economical: We strive to do more with less. We’ll always be limited in time, money, and energy, especially compared to our ambitions. We must use our limited resources on what matters and regard constraints as motivators. 
  • Transparency: Context and accurate information are the foundation of strong decision making. We share information openly, honestly, deliberately and broadly.
  • Team-oriented: People at M1 may play different roles, but we’re all on the same team. Together, we can achieve more. We maintain a low ego, make everyone feel welcome, trust one another, and seek out and respect different perspectives.
  • Challenged, But Not Overwhelmed: We are curious people who always want to grow. We support growth through high standards, clearly defined responsibilities, and broad autonomy, with help when needed. 
  • Effectiveness: We care about performance and results, not specific methods. Different problems may require creative brilliance or a simple idea; grinding hard work or casual effort; or disciplined process versus scrappy implementation. Effective people do what’s needed to get the right things done and deliver intended results.
  • Integrity: We do the right thing. When we make mistakes, we own and correct them. We’d be proud if our actions are shared with our family, friends, and strangers. Everyone can count on us to act according to our values. This trust must never be broken.
