Cruz, a successful hard tech company, was co-founded by Kyle, who previously worked on the MIT autonomous car team and aimed to create a commercial version of that technology.

The story of Scale AI exemplifies a classic startup journey, where founders pivoted from an unrelated idea to successfully address the demand for data labeling in AI, particularly for self-driving cars.

Successful startup founders often have unique experiences from previous jobs that inform their ideas, as seen with the founder of Salient, who built an AI voice agent for loan processing based on insights from working at Tesla.
