- Integrates with the nine tax engines large US firms actually run, instead of asking them to migrate
- Named Top 25 and Top 100 accounting firms as customers — the strongest available evidence for enterprise software
- Investor group implies serious diligence and the funding to still exist several seasons from now
- Headline efficiency figures carry no stated baseline, sample or methodology, and one of them is not a measurable quantity
- Entity and fiduciary coverage is still arriving, so firms whose pain is partnership work are buying a roadmap
