Apparently they were 8+ people, in 2024 team size was 6 and were hiring 2 more [0] and in 2020 they had $2m+ ARR [1].
Honestly, while I feel bad for the people who lost their jobs the news aren't exactly surprising. Overhiring is a game for VC funded OSS like bun, not usually a good idea for bootstrapped companies.
