Uncountable has built an enterprise software platform for R&D organizations to minimize the number of experiments required to reach a higher level of performance. By using the platform, scientists have instant access and search-ability to all of their previous formulations, instead of digging through disparate spreadsheets. And with previous experimental records properly structured and stored, Uncountable's artificial intelligence engine can be manipulated to provide the best formulation suggestions in order to achieve new product goals.

For the past decade, Namecoach has worked with universities, enterprises, and global platforms to help people pronounce names correctly across languages and cultures. And we built the largest verified pronunciation dataset of its kind, combining human recordings, phonetic transcription, and machine learning. We're now building Euphonia (euphonia.namecoach.ai), a pronunciation intelligence platform for voice AI. Voice agents are proliferating, but they all break on the same problem: names and out-of-vocabulary words. A patient relations agent mispronounces a drug name. An enrollment assistant butchers a student name. Voice agents lose trust the moment they get a word wrong, and the TTS providers building these models can't easily fix it. Our pronunciation data, verified by humans across languages for over a decade, is a critical proprietary asset which Euphonia turns into a drop-in pronunciation layer for any voice agent or TTS product. Universities, Fortune 500 enterprises, and major sports organizations rely on us today. We're now building the pronunciation layer voice AI needs tomorrow.
