Arize reaches $38 million to develop an enterprise MLOps platform

Arize AI, a startup developing a platform for machine learning operations, today announced that it has raised $38 million in a Series B round led by TCV with participation from Battery Ventures and Foundation Capital. Bringing Arize’s total capital to $62 million, CEO Jason Lopatecki says the new cash will be used to scale R&D and double the company’s 50-person staff for the year. next.

Machine learning operations, or MLOps, involve deploying and maintaining machine learning models in production. Similar to DevOps, MLOps aims to increase automation while improving the quality of production models – but not at the expense of regulatory and business requirements. Given the broader interest in machine learning and enterprise AI, it’s no surprise that MLOps are predicted to become a large market, with IDC put scale of about $700 million by 2025.

Arize was founded in 2019 by Lopatecki and Aparna Dhinakaran, after Lopatecki sold a previous startup – TubeMogul – to Adobe for about $550 million. In fact, Lopatecki and Dhinakaran first met at TubeMogul, where Dhinakaran was a data scientist before joining Uber to work on machine learning infrastructure.

“After watching group after group – year after year – not understanding what was wrong with the models going into production and struggling to understand what the models were doing once deployed. , we came to the conclusion that something was fundamentally missing,” Lopatecki told TechCrunch in an email interview. “If the future is driven by AI, then there needs to be software to help humans understand AI, break down problems, and fix them. AI without the observability of machine learning is not sustainable.”

Arize is certainly not the first to tackle these challenges in data science. Another MLOps provider, Tacton, which recently raised $100 million to build its machine learning model testing platform. Other players in the space include Galileo, Modules, Shoes and Grid.aithe company finally raised $40 million in June to launch a collection of components that add AI capabilities to apps.

But Lopatecki claims that Arize is unique in some respects. The first is a focus on observability: Arize’s embedded product is designed to look inside deep learning models and understand their structure. “Bias Tracing” complements it, a tool that tracks biases in models (e.g., facial recognition models recognize Blacks less frequently than subjects with brighter skin) – and try to trace back the data that caused the error.

Most recently, Arize launched an embedded bias tracking feature that attempts to detect when models have become less accurate due to outdated training data. For example, drift monitoring could alert Arize customers if a linguistic model responds with “Donald Trump” to answer the question “Who is the current President of the United States?”

“Arize stands out… [because] we’re focused on doing something hard well: machine learning’s observability,” says Lopatecki. “Ultimately, we believe that machine learning infrastructure will be like software infrastructure with some of the best, market-leading solutions used by machine learning engineers to create great machine learning. great.”

Arize’s second differentiator, says Lopatecki, is its field expertise. Both he and Dhinakaran hail from academia and draw from a practitioner’s background, he notes – having built a machine learning infrastructure and managing problems with models in production.

“Even for teams that are experts and thought leaders, it’s important to keep up with every new paradigm architecture and every new breakthrough,” says Lopatecki. “As soon as teams finish building their latest model, they often move on to the next model the business needs. This leaves very little time to dig into the billions of decisions these models are making on a daily basis and the impact these models have on both businesses and people… That’s why Arize spent over a year building a product to track deep learning models and workflows designed to debug where they went wrong. “

Some might argue (correctly) that Arize’s competitors also have experts in their ranks and monitoring and observation solutions in their product suite. But judging by Arize’s impressive client list, the startup is making a convincing pitch. Uber, Spotify, eBay, Etsy, Instacart, P&G, TransUnion, Nextdoor, Stitch Fix and Chick-fil-A are among Arize’s paid customers, and the company’s free tier – launched earlier this year – has more than 1,000 users.

However, mother is the word about annual recurring revenue. Lopatecki is adamant that Series B capital will give the company “a spacious runway” macro environment to be loved.

“In healthcare, there are teams using Arize to ensure that cancer detection models use consistent imaging in production across multiple cancer types. In addition, there are groups that use Arize to ensure that the models used in standard care decisions and coverage experiences are consistent across racial groups,” added Lopatecki. “As models get more and more complex, we’ve found that even the largest and most complex machine learning teams have found that they would rather invest their time and energy in building better models than in building better models. build a machine learning observation tool… Arize helps students improve returns on model investments and quantify results for business leaders [and provides] market leading software to track the risk of investments in AI. “
