What makes someone successful on your team?

Curiosity and grit will set you up for success on our team! When I joined Alloy, I learned about the relationship between identity and bank applications. From there, I created a knowledge base for clients, and today I manage our support team.

How do you empower your team to be more creative?

One of Alloy’s values is to “be bold”. This helps the team to have a go-getter, proactive attitude towards challenges big and small as we scale. We also feel supported by our team to try out new strategies, set 1:1 time with SME's across the org. for advice, and be encouraged to fail because we learn so much and grow in that experience.
