Six most recent funded-startup entries tied to Rye span 2021-04-14 (Curemark, $2M) through 2025-05-21 (Greenbriar Equity Group, undisclosed). The largest disclosed round is Cipher Mining’s $150M on 2025-05-20, which dwarfs the next-largest disclosed amount (RIP Medical Debt’s $350K on 2023-06-07) and leaves the remaining disclosed deals clustered far lower ($3M, $2M, and $15M). Sector-wise, Financial Services appears in two rows (Greenbriar Equity Group on 2025-05-21 and RIP Medical Debt on 2023-06-07), while other sectors are singletons (Blockchain and Cryptocurrency, Commerce and Shopping, Events, and Biotechnology). The list also compresses into a short recency cluster: three entries fall between 2025-05-20 and 2025-05-21 (Cipher Mining, Greenbriar Equity Group), plus Knoops on 2024-09-24. Finally, disclosure is uneven: 2 of 6 entries show undisclosed/“Series Unknown” classification in the amount column context (Greenbriar Equity Group is undisclosed; the other four have disclosed dollar amounts).

Frequently asked
What stands out in disclosed deal sizes, and where does the next tier begin?
Cipher Mining’s $150M on 2025-05-20 is an outlier compared with the rest of the disclosed amounts in this list, including Serendipity Labs’ $15M (2021-08-20) and Knoops’ $3M (2024-09-24). After the $150M round, the next-largest disclosed amount is RIP Medical Debt’s $350K on 2023-06-07.

All other sectors shown—Blockchain and Cryptocurrency (Cipher Mining), Commerce and Shopping (Knoops), Events (Serendipity Labs), and Biotechnology (Curemark)—appear once each.

The smallest disclosed amount is Curemark’s $2M on 2021-04-14. That sits below Knoops’ $3M (2024-09-24) and far below Cipher Mining’s $150M on 2025-05-20.
Is there an obvious stage or disclosure pattern across these Rye-linked rows?
Disclosure is mixed: Greenbriar Equity Group is listed with an “undisclosed” amount (2025-05-21), while the other five rows show dollar amounts ($150M, $3M, $350K, $15M, $2M). Stage labels also skew toward “Series Unknown” in this view (e.g., Greenbriar Equity Group, Cipher Mining, Knoops, RIP Medical Debt), with one explicit “Private Equity” label (Serendipity Labs, $15M on 2021-08-20) and one explicit “Venture - Series Unknown” label (Curemark, $2M on 2021-04-14).
