Otter.ai Tech Stack

AI meeting transcription and note-taking platform processing billions of conversations

Software Development Mountain View, California 51–200 employees Privately Held

Otter.ai transcribes and summarizes meetings at scale, processing over 1 billion conversations through a polyglot backend (Python, Go, Java, C++) running on Kafka, Cassandra, and AWS. The tech stack reveals a data-intensive operation: Elasticsearch for search, Snowflake + BigQuery + Databricks for analytics, and Apache Airflow + dbt for pipeline orchestration. Engineering-heavy hiring (16 of 32 open roles) with a security-first lean (CI/CD hardening, cloud architecture design, infrastructure-as-code automation) suggests the company is solving scale and compliance challenges head-on as it expands into enterprise deployments.
