🤖 AI Activity Report
Status: very-active
AI Reasoning: Found a PR Newswire press release showing Caleb Sima participated in ProjectDiscovery’s $25M Series A on August 17, 2023. Calculating time since that investment to November 1, 2025: that date is 2 years, 2 months and 15 days later, which is more than 12 months. Therefore tag should be ‘low-active’.
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.
