The analysis largely holds tbh even if the ARR is higher. At some point, euphoric private market valuations don't hold when there are public comps (of which there are many for Airtable)
And the company if you compare to those public comps is still worth a fraction of its last valuation although to their credit is probably is worth more than its total equity funding.
I'm happy to update the analysis if someone has verifiable revenue figures - else I have to use the figures that have been leaked or given to the press historically.
