Founded by Jennifer Song & Adam Mhatre
Jennifer studied physics, math, and CS at Harvard and built quantum optics experiments across Harvard, Stanford, and QuEra (a Google-backed quantum computing startup).
Adam studied computational physics at Stanford, and worked on plasma simulation for fusion and large-scale astrophysical modeling of black holes.
They have both felt the pain of inefficient engineering design firsthand — and built Photonium to fix it.
Optical systems are mission-critical across many high-growth sectors — including quantum technology, biomedical imaging, LiDAR for defense and autonomous vehicles, and metrology for semiconductor fabrication.
But designing them is a nightmare:
Engineers spend countless hours on repetitive workflows — constrained by tools that haven’t changed in decades.
Photonium is building the electronic design automation (semiconductor EDA) for optics. They work with complex optical setups across industries and handle the entire design process — from system generation and optimization to simulation, tolerancing, and sourcing.
Photonium enables companies to:
Optical systems are foundational to cutting-edge technologies, from quantum computing to semiconductor fabrication. Yet, outdated tools and fragmented workflows slow innovation and inflate costs. The team hopes to eliminate these bottlenecks and accelerate innovation across industries.
