All our backend engineers were on the S3 filesystem team. I'm Grant Slatton, founding engineer at Row Zero, and before this I designed and led the team that built S3's new filesystem, ShardStore (check out this paper https://www.cs.utexas.edu/~bornholt/papers/shardstore-sosp21.pdf https://www.cs.utexas.edu/~bornholt/papers/shardstore-sosp21...). Our other Row Zero backend engineers (Breck, Erich, Greg) were all on the team. Our frontend guy is ex-Airtable.
