About Phaidra

Phaidra is building the future of industrial automation.

The world today is filled with static, monolithic infrastructure. Factories, power plants, buildings, etc. operate the same theyve operated for decades — because the controls programming is hardcoded. Thousands of lines of rules and heuristics that define how the machines interact with each other. The result of all this hardcoding is that facilities are frozen in time, unable to adapt to their environment while their performance slowly degrades.

Phaidra creates AIpowered control systems for the industrial sector, enabling industrial facilities to automatically learn and improve over time. Specifically:

• We use reinforcement learning algorithms to provide this intelligence, converting raw sensor data into highvalue actions and decisions.
• • We focus on industrial applications, which tend to be wellsensorized with measurable KPIs — perfect for reinforcement learning.
• • We enable domain experts (our users) to configure the AI control systems (i.e. agents) without writing code. They define what they want their AI agents to do, and we do it for them.
• Our team has a track record of applying AI to some of the toughest problems. From achieving superhuman performance with DeepMinds AlphaGo, to reducing the energy required to cool Googles Data Centers by 40%, we deeply understand AI and how to apply it in production for massive impact.

Phaidra’s ability to achieve its mission is determined by our ability to work together — as defined by our core values: Transparency, Collaboration, Operational Excellence, Ownership, and Empathy. We seek individuals who embody these values, as they are instrumental in ensuring our team consistently delivers excellence and fosters an engaging and supportive culture

Phaidra is based in the USA, but we are 100% remote with no physical office. We hire employees internationally with the help of our partner, OysterHR. Our team is currently located throughout the USA, Canada, UK, Italy, Sweden, Spain, Portugal, the Netherlands, Singapore, Australia, and India.
