🤖 AI Activity Report
Status: not-found
AI Reasoning: Searches including Ten Eleven Ventures team page and other public bios (Ten Eleven Ventures site, 1011vc, Wikipedia, EFF) show Jon Callas as an advisor and co-founder of PGP and Silent Circle and note roles at Titaniam and Ten Eleven Ventures, but contain no records of any investment or portfolio company with dates. I could not find any press releases, Crunchbase entries, news articles, or funding announcements showing Jon Callas making an investment in recent years. Therefore there is no verifiable recent investment activity to date; unable to determine a last investment date from public sources.
Angel activity thresholds:
Low Activity – Only known angel investments more than 12 months ago.
Active – Known angel investments between the last 12 and 6 months.
Very Active – Known angel investments in the last 6 months.
