Hex raises $100M after rebuilding its data product around AI agents

What Hex announced

Hex Technologies sells a platform where teams analyse data and build reports. As FourWeekMBA reported, the company has raised $100 million, valuing it at $1.2 billion. CEO Barry McCardel shared the news in a company blog post dated 27 October, and Techmeme linked to Forbes' coverage on 2 November.

Peak XV and 137 Ventures led the round. Amplify, Avra, a16z, Next Legacy, Redpoint, Sequoia and Zero Prime also took part, according to the post. Techmeme calls it a Series D, which is a later-stage funding round.

Alongside the money, Hex released Hex 4.0. McCardel describes it as a complete rewrite aimed at a world where AI agents, meaning programs that carry out multi-step tasks on their own, do much of the analysis.

Why start over after a strong quarter

McCardel says the decision came a few months earlier, right after the strongest quarter Hex had ever had. So by the company's own account, this was not a rescue from a slowdown. It chose to discard a six-year-old design while things were going well.

His post lists what was wrong with the old architecture. The set of tools that Hex's own built-in agent could use had swollen to hundreds. Outside agents could only reach Hex through a narrow connection called MCP, a standard way for AI agents to plug into other software. And the engine that runs the calculations was not built for the way agents work, which is fast, in parallel, and through many repeated tries.

The guiding idea of the new version, McCardel wrote, is that "everything is code." In practice, that means treating analyses as something both people and agents can write, run and inspect in the same way.

What customers were already doing

The post also describes behaviour Hex saw outside its own product. Customers were using agents such as Cursor, Codex, Cognition and Claude, plus custom-built ones, to generate dashboards and reports quickly, a habit often called vibe coding, where you describe what you want and let an AI write the code.

The results were often shared as plain HTML files. That is fast, but those files carried no access rules, no record of where the data came from, no context about what the numbers meant, and no way to watch how they were produced. For a company's finance or sales figures, that is a real risk.

As FourWeekMBA reads it, Hex is betting that analysis done by outside agents will keep growing, and that it can be the place where that work gets permissions and a paper trail. It does not expect people to open Hex first and start there.

The jab at older software

McCardel aimed a pointed comment at older business intelligence tools, the software companies use for dashboards and reports. He argued that adding a chatbot sidebar to those legacy platforms will not be enough. That is a competitor-facing claim from a company with something to sell, so read it as a position rather than a finding.

Hex says more than 2,500 customers use its product. FourWeekMBA did some arithmetic with the figures. The new money is about 8.3% of the valuation, and the valuation works out to no more than roughly $480,000 per customer. Those are the outlet's calculations, not numbers Hex published, and the second is only an upper bound.

What we do not know

Hex did not share revenue, growth rates or total funding raised in the post. Claims like the 2,500 customers and the record quarter are the company's own statements. Nothing independent confirms how well Hex 4.0 works, or whether customers will move their agent-built reports into it.

The broader signal is still useful. Software that was designed for a person clicking through screens is being rebuilt for agents that call it thousands of times, and investors are funding that rebuild.
