ETL Speaker Series: Alexandr Wang, Scale AI
Key ideas
Wang explains how a stalled side project pointed him to data as AI's bottleneck, and what Scale taught him about ambition, people, lost customers and acting through doubt.

Follow the bottleneck you run into
Wang says that while at MIT he tried to build a fridge camera to catch roommates taking his food, and gave up within hours because of how much data it would need. He reasoned data would be a pillar of AI, saw few people working on it, and took AWS and Stripe as patterns for a platform company. He adds that he did not have all the answers and only thought it worth exploring.

Don't wait until you feel ready
Wang says he only started in earnest when school ended, after putting the work on hold for finals, and that momentum over the summer left little option but to keep going. He calls the choice between your current life and a startup a false dichotomy. His advice is to create room to explore and then see whether momentum builds.

Ambition may cost no extra work
Wang argues an ambitious project and a modest one might take the same amount of work, so aiming higher gives a better feedback loop with the world. He says this is a stated Scale value.

People matter more than you expect
Asked what he would tell his earlier self, Wang says people matter about ten times more than he understood, despite already focusing on them. Asked about his hardest challenges, he names getting employees, investors and customers to buy into his view of the future.

Keep early customers, and keep moving
Wang recounts Scale's first very large customer leaving after the company lost focus on it while chasing other big accounts, which left him asking whether there was a business at all. He takes from it a stronger commitment to putting customers first. He also says self-doubt is part of the journey, and that even a poor action is better than none.
In Alexandr’s words
“At the end of the day the algorithm is only as good as the data that it's trained on”
