ML Observability Company Arize AI Raises $19 Million

By Amit Chowdhry ● Oct 4, 2021
  • Arize AI, a leader in ML observability and model monitoring, announced it raised $19 million in Series A funding. These are the details.

Arize AI — a leader in ML observability and model monitoring — announced it has raised $19 million in Series A financing. This round of funding was led by Battery Ventures with participation from previous investors Foundation Capital, Trinity Ventures, The House Fund, and Swift Ventures. Dharmesh Thakker, general partner at Battery Ventures will join the Arize AI board.

Machine learning is known as the backbone of modern technology, powering AI systems that touch all aspects of life. But these systems are extremely complicated, and many ML practitioners don’t have the right tools or telemetry to understand how, or why creations work.

There are common problems that plague all ML models. And left undetected and unmitigated, these problems disrupt business and create negative experiences for customers, and ultimately communities and society. Adding to the complexities of AI is the lack of transparency and observability – which can lead to biased ML models that fail to protect individuals against discrimination, promote inclusion, diversity and equity, and safeguard equality.

The Arize AI founding executive and engineering teams – composed of industry veterans from industry-leading organizations including Uber, Google, Apple, Slack, Adobe and PagerDuty have charted a course for the industry’s first full-stack ML observability and model monitoring platform. And the platform is the only solution designed specifically for the ML engineers, data scientists, and other practitioners responsible for deploying and maintaining the ML models that drive business decisions and processes.

Arize AI’s Aparna Dhinakaran is one of the few women co-founders in the AI industry. And prior to co-founding Arize AI, Dhinakaran was a Ph.D. candidate in computer vision at Cornell University and before that led the design and development of Uber’s first model lifecycle management system. A season 32 contestant on The Amazing Race, she tested her limits and learned valuable life lessons, ultimately finishing amongst the race’s top 5 teams.

Since announcing seed financing in October 2020, Arize AI has gained traction among enterprises such as Adobe and Twilio that are looking to ensure production models perform as designed in the research and building phase. And other customers include organizations in financial services, fintech, healthcare, insurtech, ad tech, retail and other industries that rely on AI for fraud detection, pricing, demand forecasting and service delivery optimization.


“In the same way that tools had to be created in the software industry to track issues, manage version history, oversee builds, and provide monitoring, we’re seeing a similar trajectory in the ML space. Without the tools to reason about mistakes a model is making in the wild, teams are investing a massive amount of money in the data science laboratory but essentially flying blind in the real world.”

— Aparna Dhinakaran, co-founder and chief product officer at Arize AI

“Despite the significant effort and resources put into building and shipping models, no model is going to be perfect at processing and understanding natural language under natural conditions. The Arize AI platform provides an intuitive UI that’s easy to use and can monitor drift and performance of all models across our most advanced communication deployments. With Arize, our team of practitioners can now quickly and easily observe and continuously improve models, solving one of the core pain points to keeping our ML initiatives on track.”

— Brendon Villalobos, machine learning technical lead at Twilio

“In our business, ML models make decisions daily that determine if our customers make or lose money by deciding what ad spots to buy. The ability to quickly change what we’ve built, understand how it’s different from the previous models and know where it has problems is mission-critical, particularly in the context of our commitment to innovation and leadership in the increasingly privacy-focused advertising environment.”

— Alok Kothari, director of machine learning at Adobe

“While almost every business is massively investing in artificial intelligence for competitive advantage, very few are able to deliver models continuously with a high return on that investment. Arize AI is successfully eliminating barriers to a future where ML practitioners understand why a machine learning model behaves the way it does after it is deployed into the real world. Ultimately, as AI systems become increasingly complex, their capabilities and limitations will become more profound and will require a highly advanced level of useful, meaningful human oversight to ensure they are contributing to, not detracting from, societal well-being.”

— Jason Lopatecki, CEO of Arize AI

“As the world becomes increasingly AI-centric, there will be a few primary categories of ML infrastructure tools that truly matter for data organizations… Billions have been invested in two categories, data preparation and ML model building; leading to a flood of models being deployed across every industry. However, the actual value of a model’s impact on business and customers is often hazy at best. Similar to how solutions help teams manage their software infrastructure investments, organizations that are serious about ML need to employ a toolchain for ML infrastructure.”
