Core Values
-
Team First: We over me. No one left behind.
-
Extreme Ownership: We own our work until it is done, no matter what it takes.
-
Customer Value is All That Matters: We serve customers, not the engineering gods.
-
Velocity is King: Whoever ships value the fastest wins.
-
Tortoises are Faster Than Hares: Always seek deep understanding — learning compounds over time.
-
Done is Better Than Perfect: Start with the skateboard; end with the Lamborghini.
-
Details Matter: At every stage of fidelity, excellence is in the details. Key Theme We put the customer and the business before code. We operate on a Scrumban workflow with commitments tied to product launch dates. Builders own shipping features end-to-end — from customer discovery through QA.
