Uninspiring, mercurial leadership with a bit of an ivory tower mentality.
No clear ICP has been identified. As a result sales will make bold promises, which are not easy to deliver.
Very few live clients.
No clearly defined product roadmap. Product leadership will ultimately be undone by their sheer arrogance.
Lack of transparency - most startups have monthly/quarterly town halls. Finbourne would schedule them and then cancel last minute.
