What believers are saying

  • June 2026 product updates targeted agentic AI evaluation and multimodal interfaces.
  • HumanSignal raised $25 million from Redpoint and existing investors, supporting expansion.
  • The Erud AI acquisition positions HumanSignal for frontier model training demand in 2026.

What critics are saying

  • August 2026 CVE-2026-72560 exposed SSRF in Label Studio through version 1.24.0.dev0.
  • Open-source competitors can copy labeling features quickly, compressing HumanSignal’s software margins.
  • If Services fails, Enterprise buyers can bypass HumanSignal by hiring cheaper annotation vendors.

What makes HumanSignal unique

  • Label Studio 1.23 added vector annotation, interactive task source, and data manager improvements in 2026.
  • HumanSignal combines open-source Label Studio with enterprise workflows, permissions, and custom interface building.
  • November 2025 Erud AI acquisition added physical data labs and expert annotation services.

Heartex’S Label Studio Makes Labeling Audio For Ml Easier

Heartex, the well-funded machine learning data labeling startup, is launching a major update to its platform today that will open up new use cases for its tools by making annotating audio files in the commercial and open source versions of its Label Studio a lot easier for its users. These updates include a new user interface, optimized for working with audio files, the ability to annotate longer files (up to two hours in length) and millisecond controls in the built-in annotation tool. There is also now a new rendering engine for displaying waveforms. In a previous update, Heartex also added to its tool features like frame-by-frame video object tracking and an overhauled annotation UI.The company says about 150,000 users are currently relying on Label Studio, with more than 95 million annotations created so far.Image Credits: Heartex“When we were originally thinking about building the data labeling solution, we did a lot of data scientist interviews,” Heartex co-founder and CEO Michael Malyuk told me. “And what we figured out is that many of them say they don’t have enough flexibility with existing tools. There is a tool for images, but you can only put a single image on the screen
