🤖 AI Activity Report
Status: low-active
AI Reasoning: Search results and Wikipedia show Martin Roscheisen’s notable investments and activities concentrated around Diamond Foundry (e.g., launching Diamond Foundry in 2015 and acquisition of VRAI in 2016). No evidence of any investment activity or new startup investments in the past several years (no investments found in 2024 or 2025). The most recent found involvement tied to a company (VRAI/Diamond Foundry) dates from 2023 (news about VRAI/Diamond Foundry operations) or earlier; no recent seed investments such as Sidecar Technologies were dated within the last 12 months. Calculating from the absence of any investment within the last 12 months places him in the low-active category.
