About
Hazel AI was founded to solve one of enterprise technology's most persistent and costly problems: the accumulation of aging, complex legacy codebases that organizations cannot afford to maintain but cannot afford to abandon. The company's mission is to automate the modernization of enterprise software through autonomous AI agents that understand, transform, and re-architect legacy systems at a speed and scale that human engineering teams cannot match. Its core technology relies on multi-agent orchestration to analyze existing code, generate transformation plans, and execute migrations across large, heterogeneous code environments.\n\nHazel AI's platform targets large enterprises with significant investments in legacy systems across mainframe, COBOL, Java, and other aging technology stacks. Rather than generating incremental code suggestions, Hazel operates as a full transformation engine capable of handling end-to-end modernization engagements. The platform coordinates multiple specialized AI agents, each responsible for distinct stages of the transformation process, enabling parallel execution across millions of lines of code.\n\nHazel AI positions each engagement as a high-ROI initiative, claiming $20 to $50 million in annual outcomes per customer through reduced maintenance costs, improved developer velocity, and decommissioned legacy infrastructure. This outcome-based framing differentiates Hazel from tool vendors and aligns it more closely with systems integrators, allowing it to command premium pricing. The platform addresses a multi-hundred-billion-dollar global market in legacy modernization, where enterprises are increasingly motivated to accelerate transformation as AI raises the competitive cost of technical debt.

About
ElevenLabs was founded in 2022 by Piotr Dabkowski and Mati Staniszewski, two former Google and Palantir engineers who set out to break the language barrier using AI voice technology. The company specializes in AI-powered voice synthesis, cloning, and dubbing, enabling developers and enterprises to generate human-quality speech in over 30 languages. Its core technology combines deep learning models trained on massive speech datasets to produce natural-sounding voices indistinguishable from real humans.\n\nElevenLabs offers a suite of products including its flagship text-to-speech API, voice cloning tools, and an AI dubbing platform that localizes video content while preserving the speaker's original voice. Its products target a broad audience—from indie developers building audio apps to large enterprises deploying voice interfaces at scale. Key differentiators include ultra-low latency streaming synthesis, fine-grained voice customization, and a growing library of pre-built AI voices across accents and styles.\n\nElevenLabs has grown rapidly, surpassing $330M in annualized revenue and serving over 1 million developers. Enterprise clients include Deutsche Telekom, Spotify, and leading media companies. In February 2026, the company closed a $500M Series D at an $11B valuation, cementing its position as the market leader in AI voice. Its APIs power podcasts, audiobooks, video games, and customer service bots worldwide, making ElevenLabs the default infrastructure layer for AI-generated audio.
