"the team" here seems to be a trio of research scientists/data scientists? (Some famous in their research community bubble) Competent product/sales person, and engineering person seems missing for this to succeed. Especially if they used to rely on the eng infrastructure of giants. They seem smart folks so probably can cover the software engineering gap, especially with $100m to outsource some of the hard problems to some cloud infra. But I'd be more confident if they had started with a co-founder that's more product/sales oriented.
