TensorStax - Seed Round

$5.5M Raised

Some startups chase buzz. TensorStax? They chase bottlenecks, and beat them into submission with deterministic precision.

Founded in December 2023 by Aria Attar (ex-MongoDB, Otto, Autosnap) and Biraj Silwal (former Dell Technologies lead, now orchestrating machine learning like a conductor in a data symphony), TensorStax just locked in a $5.5M seed round to drag data engineering into the era of AI autonomy. And they’re doing it with something the space rarely sees, LLM driven agents that don’t guess, they compile.

Glasswing Ventures led the charge, Kleida Martiro saw the signal through the noise. Bee Partners, S3 Ventures, Gaingels, and Mana Ventures joined the movement, with Bee doubling down from their earlier pre-seed bet. That’s not just conviction. That’s foresight with teeth.

So what’s under the hood? TensorStax built a deterministic LLM compiler, a control layer that translates the chaos of natural language into airtight code that holds up in enterprise grade data environments. These aren’t chatbots in cosplay. These are agents that read your request, understand the tools in play, resolve dependencies across systems, validate syntax, and push the code live, inside your VPC, no data ever leaving your ecosystem. You say “build a dbt model,” it delivers production-ready code backed by compliance-grade auditing. Zero hallucinations. Maximum trust.

Now they’re moving fast. Internal benchmarks show 85–90% success rates in pipeline generation, blowing past the industry’s shrug-worthy 40–50% average. That’s not just performance. That’s dominance.

With market demand surging, thanks to the lopsided 1:250 ratio of data engineers to software engineers, and a $66.7B addressable market on the horizon, TensorStax isn’t filling a gap. They’re paving a new road for how teams build, scale, and govern their data layers. No code spaghetti, no schema whack-a-mole, no orphaned DAGs gaslighting your ops team at 3 a.m.

The move is calculated: start mid-market, prove in fintech and healthcare (where broken pipelines aren’t just annoying, they’re regulatory liabilities), then scale through certified integrations with Snowflake, Databricks, and the clouds we all orbit.

TensorStax is doubling down on agentic orchestration with real structure, not prompt-driven guesswork. This is software engineering with swagger, clean, crisp, and finally trusted.

Aria and Biraj aren’t just co-founders. They’re architects of the post-fragile data stack. Keep watching.
