TensorStax gets $5M in funding to automate data engineering with deterministic AI agents – News

A startup called TensorStax says it’s looking to bring artificial intelligence-powered automation to the unyielding world of data engineering after raising $5 million in seed funding.

Today’s round was led by Glasswing Ventures and saw participation from Bee Partners, S3 Ventures, Gaingels and Mana Ventures.

TensorStax is building AI agents that can perform tasks on behalf of users with minimal intervention to the challenge of data engineering, which has traditionally always been considered something that’s beyond the capabilities of even the most advanced AI algorithms.

The problem with data engineering, which refers to building systems that collect and analyze data, is that it’s much more rigid than software engineering, where AI already performs exceptionally well, generating code that’s often as good as human programmers. That’s because data engineering involves dealing with strict schemas, tightly coupled pipelines and reproducibility requirements, and even the smallest of errors can totally corrupt downstream outputs.

TensorStax co-founder and Chief Executive Aria Attar said that when it comes to a task such as frontend application development, there are numerous ways an AI can create a menu component that fulfills all of the required functions for that app. But that can’t be said for data engineering tasks.

“If you need to perform a specific transformation on a thousand-column Snowflake data warehouse, there are often only one or two correct approaches to this,” Attar said. “This rigidity makes data engineering exceptionally difficult for large language models, due to their non-deterministic nature.”

A deterministic approach to data pipeline automation

The startup gets around this by creating a purpose-built abstraction layer to ensure its AI agents can design, build and deploy data pipelines with a high degree of reliability. Its proprietary LLM Compiler acts as a deterministic control layer that sits between the LLM and the data stack to facilitate structured and predictable orchestration across complex data systems.

Among other things, it does the job of validating syntax, normalizing tool interfaces and resolving dependencies ahead of time. This helps to boost the success rates of its AI agents from 40% to 50% to as high as 90% in a variety of data engineering tasks, the startup said, citing internal testing. The result is far fewer broken data pipelines, giving teams the confidence to offload various complicated engineering tasks to AI agents.

TensorStax says its AI agents can help to mitigate the operational complexities involved in data engineering, freeing up engineers to focus on more complex and creative tasks, such as modeling business logic, designing scalable architectures and enhancing data quality.

By integrating directly within each customer’s existing data stack, TensorStax makes it possible to introduce AI agent data engineers into the mix without disrupting workflows or rebuilding their data infrastructure. These agents are designed to work with dozens of common data engineering tools. For instance, they’re compatible with data transformation platforms such as dbt, processing engines such as Apache Spark, orchestration frameworks such as Apache Airflow and Dagster, and cloud data warehouse offerings, including Snowflake, Databricks, Google BigQuery and Amazon Redshift.

The startup says its customers primarily use its AI agents for building extract, transform and load, and extract, load and transform pipelines, and to optimize their performance. They can also carry out tasks related to data lake and data warehouse modeling, building schemas and transformations atop of customer’s existing infrastructures. They can aid in pipeline monitoring too, where they keep an eye out for problems, diagnose the root cause of those issues and suggest and deploy fixes when required.

The best thing is that TensorStax AI agents respond to simple commands. Users simply express what they want it to do, such as creating a new dbt model or full ELT pipeline, and it will immediately set about drafting a plan that’s customized for their data stack. Once approved, the planned workflow is transformed into production-grade code that can be deployed immediately to generate new dbt models, Structured Query Language Scripts, configurations and more. Prior to deployment, the AI agent will deterministically validate each component to ensure no problems.

A bottleneck for AI scalability

Constellation Research Inc. analyst Michael Ni told News that TensorStax is targeting a real and growing problem around the need for enterprises to simplify and stabilize data pipelines that remain incredibly fragile, complex and mostly human-dependent.

“As data analytics, machine learning and AI scale, these brittle pipelines become major bottlenecks,” Ni said. “While other companies have introduced copilots, such as Google BigQuery’s Data Engineering Agent, they tend to skip the most challenging part, which is end-to-end orchestration.”

Ni said TensorStax appears to be architecturally different to others, with its LLM compiler, its integration with existing tools and its no-customer-data-touch approach, though he cautioned that details of its solution are still somewhat sparse at present.

“It promises a more disciplined and deterministic approach to AI in data engineering, moving beyond code generation and towards agentic orchestration with compiler-like reliability,” Ni said. “It’s auditable and runs alongside popular tools without exposing customer data. These are critical capabilities in environments where broken pipelines aren’t just technical debt, but barriers to the promise of AI and analytics at scale.”

TensorStax is operating in a nascent market for agentic AI in data engineering that was valued at just $2.7 billion last year, according to Market.us. However, the prize is expected to grow much bigger, with the same study forecasting it to grow at a compound annual growth rate of 37.8% through 2034, reaching as high as $66.7 billion.

Glasswing Ventures Partner Kleida Martiro said he believes TensorStax’s unique approach, using a deterministic compiler for LLMs, is essential for giving AI agents the attention to detail required for automating data engineering tasks.

“We are confident that Aria and the TensorStax team have the perfect blend of technical know-how and business acumen to build this critical solution that will transform enterprise businesses and drive significant value creation,” he said.
