About Amigo
We build AI that puts people first. Instead of just making organizations more efficient, we ensure AI systems actually help humans thrive.
We focus on healthcare because getting things right matters most there. Our technology gives organizations confidence that their AI is working correctly before they deploy it. We use advanced testing and verification to make sure these systems are reliable enough for critical decisions.
We operate globally and follow strict regulations. We've raised $6.5M from investors including General Catalyst and GSV Ventures. Our team comes from diverse backgrounds—tech, psychology, economics, healthcare, and policy—all working together to create AI that organizations can trust and that genuinely benefits people.

Experience with cloud platforms and container orchestration technologies
Strong understanding of security best practices and experience with systems handling sensitive data
Understanding of distributed systems concepts (consensus, replication, partitioning) without necessarily having built foundational frameworks
