Scale AI, the four-year-old data labeling startup, has discovered that selling the picks and shovels needed to develop and apply artificial intelligence is big business.

The company, which created a visual data labeling platform that uses software and people to label image, text, voice and video data for companies building machine learning algorithms, has raised another $155 million. The funding round, led by Tiger Global, pushes Scale’s post-money valuation to more than $3.5 billion.
