Edinburgh-based semiconductor firm Singular Photonics has successfully raised €1.85 million ($2.15 million) in a heavily backed funding round, led by ACF Investors and featuring participation from Wren Capital, Cambridge Angels, Scottish Enterprise, Quantum Exponential and Old College Capital. The venture capital injection follows the company's announcement that former Arm CTO Dipesh Patel has joined its board of directors.
In its maiden year, Singular Photonics has already achieved double-digit growth targets, with management reporting a doubling of 2025 sales in the first half of 2026. CEO Shahida Imani highlighted the company's ability to respond to customer demands more swiftly, thanks to the funding, which will enable expansion of its sensor portfolio and deployment of new features aligned with customers' needs.
The startup was founded in February 2024 by CEO Imani, CTO Dr. Aravind Venugopalan, Professor Robert Henderson, and Dr. Neil Finlayson. Emerging from stealth mode in January 2025, Singular Photonics is a fabless innovator developing SPAD image sensors with on-chip computation. The company's technology represents a shift in image sensor capabilities, moving beyond conventional intensity measurement to precise detection and timing of individual photons, thereby enabling new imaging possibilities beyond the reach of traditional cameras.
Singular Photonics' Andarta and Sirona product lines are currently commercially available and generating revenue. The company's investment will be directed towards scaling engineering capacity and hastening the delivery of new image sensors, targeting diverse markets such as machine vision, industrial automation, physical AI, scientific discovery, and medical imaging.
ACF Investors' Managing Partner Tim Mills expressed enthusiasm for Singular Photonics' potential, noting the company's unique blend of groundbreaking sensor science and commercial viability. The investment round underscores the increasing importance of real-time photon detection in the evolving landscape of edge computing and AI applications.
