Sesame AI scores B on the Alion truth index (A is best, E worst), measured over 22 open roles re-checked against its own hiring board: 18% look like ghost listings, 0% have gone stale and 0% are the same role posted again. Its roles close in a median of 148 days. It measures how much of what this employer publishes turns into a real, finite search - not the employer as a workplace. How the index is computed
Overview
Sesame AI is a company founded in 2022 that develops conversational speech models with unusually natural timing and prosody. Its demonstration voices drew wide attention for sounding present in a conversation rather than reading text aloud, and it released a base speech model openly. The company is also building lightweight eyewear intended to keep an assistant available throughout the day.
