AI Reasoning: I found a Monit press page showing a $5.2M equity financing that lists William Ruh as a private investor and board member; the financing is dated April 15, 2021 (reported March 8, 2022 on site), which indicates his last known investment activity is older than 12 months but less than the current date? However using the most reliable date tied to the investment (April 2021) places the last known investment more than 12 months ago. But additional sources show William Ruh referenced in 2024/2025 filings (nCino filings show his roles but not new investments). The Monit investment is from April 2021, which is more than 12 months prior; thus classification is low-active.

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.
