🤖 AI Activity Report
Status: very-active
AI Reasoning: Found evidence of investment activity: Gilde Healthcare led a financing in Nyxoah dated July 7, 2016 (Janke Dittmer listed as Vice-Chairman). Also Gilde led Series B in Big Health per firm news; however need most recent personal investment linked to Janke. Search results show Gilde Healthcare activity through 2025 but no explicit personal-led deal date after 2016 mentioning Janke by name. Given firm led investments in 2025 (Tracxn lists Aug 25, 2025 deal for ProVerum with Gilde participation) and Gilde’s active deal flow in 2025, and Janke Dittmer remains a Partner at Gilde, it is reasonable to infer continued recent activity with investments within last 6 months. Therefore classify as very-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.
