Bose Built a Business Around the Part of Sound You Cannot See
For six decades, Bose has sold a deceptively simple promise: make the machinery disappear and let the listener feel the result. Its next act stretches that research habit from headphones and car cabins to luxury hi-fi and the software inside other brands' devices.
Chipiron
Chipiron is a Paris-based medical-imaging startup building a compact, low-cost MRI scanner that runs at an ultra-low magnetic field (below ~30 millitesla, roughly 1,000x weaker than a hospital MRI). Its patented low-Tc SQUID quantum detection system plus AI noise cancellation and reconstruction are designed to recover clinical-grade image quality without a shielded room, without helium, and at a fraction of the cost, size, and infrastructure of conventional machines. The company's stated aim is to make MRI accessible everywhere, starting with breast imaging, and eventually reach patients, clinics, and remote settings that today's scanners can't serve.
Incept AI
Incept AI is a New York-based voice AI company building order-taking systems for quick-service restaurants, starting with the two hardest environments in the business: the drive-thru and the phone. Founded in 2024 by former Amazon and Presto Automation engineers, Incept pairs a proprietary neural audio engine that strips out background noise, echo and crosstalk with foundation models and POS integrations, so the AI can complete restaurant orders end-to-end without a human stepping in. The company says its system reaches 95%+ order completion without human intervention, well above the roughly 83% where most competitors escalate to a person, and raised a $3 million pre-seed round led by Rally Ventures in early 2025.
Krisp
Krisp is a voice AI company that strips background noise, voices, and echo from live calls using deep learning, then layers transcription, meeting notes, accent conversion, and real-time translation on top. Founded in 2017 by ex-Twilio engineers, it now processes 75+ billion minutes of audio a month for contact centers, BPOs, Discord, and millions of remote workers.
Sanas
Sanas builds real-time speech understanding AI for contact centers - accent translation, language translation, noise cancellation and speech enhancement that runs live on a call without losing the speaker's voice or emotion.
