Weights & Biases raises $45M for its machine learning tools
Weights & Biases, a startup building tools for machine learning practitioners, is announcing that it has raised $45 million in Series B funding.
The company was founded by Lukas Biewald, Chris Van Pelt and Shawn Lewis Biewald and Van Pelt previously founded CrowdFlower/Figure Eight (acquired by Appen). Weights & Biases says it now has more than 70,000 users at more than 200 enterprises.
Biewald (whom I’ve known since college) argued that while machine learning practitioners are often compared to software developers, “they’re more like scientists in some ways than engineers.” It’s a process that involves numerous experiments, and Weights & Biases’ core product allows practitioners to track those experiments, while the company also offers tools around data set versioning, model evaluation and pipeline management.
