AI Reasoning: LinkedIn shows Jonathan Bik as active investor roles through 2024 and current roles in 2024-2025 (Co-Founder at Square One Labs starting Feb 2024; Pre-Seed Lead Investor at Stealth starting Aug 2024). I found a profile on Startup Nation Finder dated Aug 27, 2025 indicating involvement as investor at J-Impact Fund; NFX/Signal shows activity in 2023-2024. The most recent investment-related role began Aug 2024, which is less than 6 months prior to the cutoff date used for classification, indicating recent investing activity. Notable startup involvement includes Stealth (pre-seed lead investor). Therefore classify as very-active.
