Shashank Agarwal: Building Noveum AI and API.market

Shashank Agarwal is the founder and CEO of Noveum AI and creator of API.market. His work connects two practical parts of the AI ecosystem: helping developers and agents access tools, and helping engineering teams evaluate what those agents do.

The company-building story began before either platform. It includes technical publishing, machine learning infrastructure, a reading app and the API business that grew from a component inside it.

Building before the current companies

Agarwal began publishing hacking tutorials on HackItEasy while still in school. He later founded Dailyjag, a media business listed in his career history from 2008 to 2020.

During his master's studies at The Ohio State University, he built Hopdata, an automated machine learning platform. His later career included Expedia, the original AWS SageMaker launch team, Amazon's ML platform work, engineering leadership at Activeloop and Levity, and ML-powered personalization at Amazon Prime Video.

Those roles are part of his public career history. They connect his present founder work to years spent building and operating software around machine learning.

The path from PipFeed to API.market

PipFeed began as a personalized reading app. After the app was shut down, its article-parsing service continued as an API product.

The pivot appears in a dated November 2023 founder update. API.market's origin documentation describes how selling that service led to a broader problem: API providers needed infrastructure for metering and commercial operations.

That problem became the basis for a marketplace. API.market brings together discovery, API access, provider publishing and billing. Its hosted MCP gateway also gives compatible AI clients a connection to marketplace tools.

The progression is concrete: a service built for one application became an independent API, and the experience operating that API informed a platform for other providers and developers.

A dated view of scale

As checked on October 29, 2026, the API.market homepage reports 18,800+ developers, 1,360+ APIs and AI models, and 6,160+ API tools. It also displays 154 million+ monthly API calls.

These are company-reported platform figures. The homepage does not specify the monthly call measurement window or how it treats retries, failures and test traffic. The developer count should not be read as active paying customers, and none of these numbers is a revenue figure. Products and tools are different units: a product can expose multiple callable tools.

The useful part of the milestone is the operational scope it represents. Running a marketplace requires more than maintaining a catalog: developers need to evaluate services and use them, while providers need access management, usage records and commercial workflows.

Noveum and production AI

Noveum AI focuses on another operational challenge: understanding how AI agents behave after a demonstration.

Its current public workflow connects instrumented traces, evaluation, failure investigation, synthetic testing and recommendations that teams can review. That focus fits Agarwal's earlier work in production machine learning and infrastructure.

On October 29, 2026, Noveum's public site lists 112 published evaluators across 15 categories. Teams select compatible scorers for their data and evaluation goals; the library count does not mean every scorer runs on every trace.

The relationship between the companies is practical. API.market provides access to APIs and AI models. Noveum helps teams examine agent behavior and the evidence behind a proposed improvement.

Writing as part of the work

Agarwal is also the author of Intelligence at Scale, a book about LLMs, agents and production AI. Its accompanying diagram collection provides another public example of his technical communication.

His writing appears on DEV, Medium, company blogs and in a former Forbes Technology Council contribution. Authorship should be checked by byline: the companies' wider publishing archives also include work credited to other team members.

For a technical founder, that combination of products, public explanations and a documented career gives readers several ways to evaluate the work.
