SoundHound's revenues are soaring, but its acceleration was mainly driven by its acquisitions of the AI restaurant services provider SYNQ3, the online food ordering platform Allset, and the conversational AI company Amelia throughout 2023 and 2024. Without those acquisitions, its core business would have grown at a much slower rate.

The primary concern for investors is whether the stock remains a solid investment following such a considerable increase.
