What does not carry over: aVenture does not send real-time hiring or launch signals, and it has no Chrome extension or CRM enrichment today, so early discovery stays in a signals tool. Older companies, non-venture-backed businesses, and non-US companies have thinner records today, and that coverage is growing.
