Feb 2025Series CAdams Street Partners (lead); Industry Ventures; SineWave Ventures; PagerDuty; Swift Ventures; Battery Ventures; TCV; Datadog; M12; Archerman Capital; OMERS Ventures; Foundation Capital$70MArize AI, a Berkeley, CA-based company founded in 2020 by Jason Lopatecki and Aparna Dhinakaran, provides a unified AI observability and LLM evaluation platform that enables teams to monitor, troubleshoot, detect issues, and improve performance for traditional ML and generative AI use cases. The platform serves enterprises including Booking.com, Condé Nast, Duolingo, Hyatt, PepsiCo, Priceline, TripAdvisor, Uber, and Wayfair, as well as government agencies. Arize Phoenix, its open-source offering, has over two million monthly downloads and is the most widely adopted AI observability library. On February 20, 2025, Arize AI raised $70 million in its Series C funding round, the largest investment in AI observability to date, led by Adams Street Partners with participation from M12 (Microsoft's venture fund), SineWave Ventures, OMERS Ventures, Datadog, PagerDuty, Industry Ventures, and Archerman Capital. Existing investors Foundation Capital, Battery Ventures, TCV, and Swift Ventures also participated, reaffirming their commitment. The funding will accelerate development of advanced features for AI evaluation and debugging, scale AI evaluation and monitoring for LLMs and AI agents, expand Arize Phoenix OSS, advance research through OpenEvals and AgentEvals, and support hiring. It enhances partnerships like deeper integrations with Microsoft Azure AI Studio and Foundry.
Sep 2022Series BTCV (lead); Swift Ventures; Battery Ventures; Foundation Capital$38MArize AI is a Berkeley-based startup founded in 2019 by Jason Lopatecki and Aparna Dhinakaran, providing an AI observability platform to monitor, evaluate, and improve machine learning models and large language models for enterprises. The platform helps detect issues, reduce uncertainty, and optimize AI performance in real-world applications across industries like retail and healthcare. On September 7-8, 2022, Arize AI raised $38 million in a Series B round led by TCV, with participation from Battery Ventures, Foundation Capital, and Swift Ventures, bringing total funding to $62 million. The funds were intended to scale operations, enhance platform capabilities, expand the MLOps platform for enterprise customers, double the 50-person headcount, and accelerate R&D. This was described as the industry's largest investment in a machine learning observability platform at the time. Arize differentiates through domain expertise from its founders' backgrounds at TubeMogul (acquired by Adobe for $550 million) and Uber, focusing on practitioner needs rather than building observability tools in-house. Competitors in the MLOps space include Tecton, Galileo, Modular, Gantry, and Grid.ai. The company has since raised a $70 million Series C in February 2025 led by Adams Street Partners, reaching total funding of $131 million, to further advance AI evaluation and observability for LLMs and AI agents.
Sep 2021Series ABattery Ventures (lead); Swift Ventures; The House Fund; Foundation Capital; Trinity Ventures$19MArize AI, a Berkeley-based leader in ML observability and model monitoring, raised $19 million in a Series A financing round on September 28, 2021, led by Battery Ventures with participation from Foundation Capital, Trinity Ventures, The House Fund, and Swift Ventures. The funding aimed to expand the team, accelerate product development, and build the industry's first full-stack ML observability platform designed for ML engineers, data scientists, and practitioners deploying and maintaining production models. The founding team includes veterans from Uber, Google, Apple, Slack, Adobe, and PagerDuty. Since its seed round in October 2020 (noted as February 2020 in some sources), Arize AI gained early traction with enterprise customers like Adobe and Twilio, ensuring production models perform as designed, alongside organizations in financial services, fintech, healthcare, insurtech, ad tech, and retail for applications like fraud detection, pricing, demand forecasting, and service optimization. The platform addresses barriers to continuous ML model delivery with high ROI, providing insights into model behavior post-deployment amid growing AI complexity. Battery Ventures' Dharmesh Thakker joined the board, aligning with Arize's mission given their investments in MLOps leaders like Databricks, Dataiku, AppDynamics, Sumo Logic, and Datadog. The round supports scaling ML observability as critical to MLOps, tackling complexities from data, systems, features, and code impacting model performance. Later rounds include Series B ($38M in 2022 led by TCV) and Series C ($70M in February 2025 led by Adams Street Partners).
Feb 2020SeedSwift Ventures; Brett Wilson; Foundation Capital; Trinity Ventures$4MArize AI launched in February 2020 with a $4 million seed funding round led by Foundation Capital, with participation from Brett Wilson and Trinity Ventures. The company provides a real-time analytics platform for AI observability, enabling teams to monitor, troubleshoot, and improve machine learning models in production. Arize AI also acquired Y Combinator-backed Monitor ML, with its team joining as co-founders. CEO Jason Lopatecki, former chief strategy officer at TubeMogul (acquired by Adobe), leads the company, while co-founder and chief product officer Aparna Dhinakaran previously built ML infrastructure at Uber. The platform delivers insights to distinguish issues between data and models, optimizing data scientist efficiency. Swift Ventures appears in later rounds, confirming investor alignment.
