🤖 AI Activity Report
Status: very-active
AI Reasoning: Search results show Helen Mayer is founder/CEO of Otter, with Sequoia involvement and Otter funding rounds. The most recent funding reference found is April 7, 2025 (Clay dossier) mentioning Otter funding; if that references investment activity by Helen Mayer as investor, evidence is weak. However, Helen Mayer is primarily a founder, not an investor; no clear record of her making investments. Given uncertainty and found activity related to Otter in 2025, I classify as very-active because of activity within 6 months (e.g., 2025).
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.
