Symbl

The company's business model is centered around a Platform-as-a-Service (PaaS) offering. It provides developers with a suite of APIs and low-code tools to process and analyze unstructured conversation data from audio, video, and text formats. Clients, which range from small developers to large enterprises, pay for these services based on usage, including subscription fees and volume-based pricing. The platform's features include real-time speech-to-text transcription, speaker separation, sentiment analysis, and the generation of summaries and action items. Its proprietary Large Language Model (LLM), named Nebula, is specifically trained on conversational data to perform generative tasks and provide deep contextual understanding. This enables clients to build conversation intelligence into their own products for use cases like sales coaching, customer support automation, and compliance monitoring.

Key funding rounds included a $1.8 million seed round in 2019, a $4.7 million round in 2020 that included investment from Amazon's Alexa Fund, and a $17 million Series A in 2021 led by Great Point Ventures. Following the acquisition, Rathore became Invoca's VP of AI Products and Strategy, while Jawale took on the role of Head of Engineering.
