Strong expertise in Next.js, React, and Tailwind for frontend development.
Proficiency in Python for backend/API development.
Familiarity with Terraform, Kubernetes (K8s), and Postgres for infrastructure and data management.
Experience optimizing web performance and improving frontend UX.

Culture: Our team is kind, collaborative, inquisitive, and inclusive – and we want to keep it that way. We have high standards for quality and ethics, and help each other learn in order to reach our objectives. We think technology is best built by teams with a diversity of background, thought, and experience.
👒 Every team member is a human first, and we strive to create a culture and environment that supports your career goals and respects all of the hats you wear in life, not just the ones that earn you a paycheck.
Our Team
We were founded in 2023 by SaaS and data experts: Josh (CEO) lead Chartbeat as CTO to $70M+ ARR and exit; David (COO and Head of Product) lead Cortico (MIT spinoff) from 0->1 as COO; Paul (CTO) ran search infrastructure at Reddit and was engineer #7 at Moat (acquired by Oracle for $850M).
Let’s build something great together! 🚀
