I am extremely skeptical of the accuracy of the adtech-over-time chart. I looked for companies I knew revenue numbers for, and I saw revenue flat and them suddenly appearing in the last box despite existing for years before his timeline even starts, for instance. [This is a bit hard to write compellingly, because you can figure out precisely who I am if I say the exact companies, and I&#x27;d prefer not to have LinkedIn be the sidechannel resource for people to violate my non-disclosures about revenue.]
