About

Lmnt (pronounced "element") is a San Francisco-based speech synthesis company that provides an ultra-low-latency text-to-speech API designed specifically for real-time voice AI applications including conversational AI agents, voice interfaces, and interactive voice response systems. While traditional TTS APIs have latency measured in hundreds of milliseconds, Lmnt's streaming architecture delivers the first audio bytes in under 100 milliseconds, enabling natural back-and-forth voice conversations without perceivable delay. The company offers voice cloning from short samples and a library of pre-built voices with emotional range, all accessible through a developer-friendly API. Lmnt is used by companies building AI companions, customer service voice bots, and voice-enabled productivity tools that require speech synthesis fast enough to feel natural. Founded in 2021 by ex-Google Brain researchers, Lmnt raised seed funding to commercialize research on real-time speech synthesis. It competes with ElevenLabs Turbo, Cartesia, and Deepgram TTS in the low-latency speech API market.

About

International Business Machines Corporation (IBM) is an Armonk, New York-based global technology and consulting company — publicly traded on the New York Stock Exchange (NYSE: IBM) as an S&P 500 component — providing hybrid cloud infrastructure, artificial intelligence software, and enterprise IT consulting through approximately 270,300 employees in 170 countries with $62.8 billion in annual revenue. Founded on June 16, 1911, as Computing-Tabulating-Recording Company through a merger orchestrated by financier Charles Ranlett Flint, renamed IBM in 1924 under Thomas Watson Sr., IBM has undergone multiple strategic transformations over its 110+ year history: building the System/360 mainframe platform (1964), launching the IBM PC (1981), selling the PC division to Lenovo (2005, $1.75B), and completing the $34 billion Red Hat acquisition (2019) that repositioned IBM as a hybrid cloud platform company. CEO Arvind Krishna (appointed April 2020) has focused IBM's strategy on three areas: hybrid cloud (powered by Red Hat OpenShift, the enterprise Kubernetes platform), AI (the watsonx platform for enterprise AI model development and deployment), and enterprise consulting. Under Krishna, IBM recorded $12.7 billion in free cash flow in 2024 (a company record), surpassed $6 billion in generative AI bookings since June 2023, and saw the stock price double — trading at all-time highs through 2024-2025. IBM announced the DataStax acquisition in 2025 to deepen watsonx's data layer with AstraDB (vector database for AI applications), DataStax Enterprise (Apache Cassandra), and Langflow (low-code AI agent development).
