Insights

Equity Capital Markets Analyst

TL;DR: A disclosed insider sale plan for 18,321 shares worth $329,778 signals routine secondary-market liquidity.

The proposed sale of 18,321 Class A shares on 10/06/2025 provides immediate liquidity for holders who acquired shares in the 12/31/2020 pre-IPO conversion. The listing of the broker and exchange (Raymond James, NYSE) indicates an ordinary brokered sale rather than a private transfer.

Recent transactions by Insight Partners (EU) XI show additional secondary activity totaling 44,589 shares across July and October dates, producing reported gross proceeds. Continue to monitor aggregated insider selling over the next 30–90 days to assess whether this represents ongoing portfolio exits or isolated liquidity events.

Corporate Governance Specialist

TL;DR: The filer affirms no undisclosed material adverse information and follows Rule 144 disclosure conventions.

The notice includes the required declaration that the seller is unaware of material adverse nonpublic information and references Rule 144 aggregation rules. The acquisition note states the shares resulted from a stock conversion before IPO on 12/31/2020, with payment described as wired to a portfolio company.

Investors should note the filing is procedural and does not itself change company fundamentals; any governance implications depend on cumulative disclosure of insider selling in upcoming filings and trading records.
