Insights

Securities Compliance Attorney

TL;DR: Filing documents a compliant Rule 144 sale and recent secondary sales by an affiliated investor.

This Form 144 provides the statutory notice required when restricted or control securities are proposed for public sale under Rule 144. It lists the broker, the exact share count (154,466) and aggregate market value ($2,780,388.00), the acquisition date (12/31/2020), and the original acquisition method (stock conversion before IPO), which supports the seller's ability to rely on Rule 144 conditions if other requirements are met.

The filing also records recent secondary sales by Insight Partners (Cayman) XI, L.P. totaling $2,269,393.84, which is useful for monitoring share distribution and potential resale activity; these entries are transactional facts and do not by themselves indicate noncompliance.

Equity Markets Analyst

TL;DR: The sale size is modest relative to total outstanding shares and reflects holder liquidity, not a material dilution event.

The planned sale of 154,466 shares compares with 324,760,095 shares outstanding, representing approximately 0.05% of the float, so the transaction is unlikely to move the market by itself. The reported recent sales by Insight Partners totaling $2.27M show ongoing secondary trading activity from a venture investor.

Investors monitoring share supply should note the exact dates and proceeds reported (07/07/2025 through 10/03/2025) as near-term data points for liquidity, but there are no disclosed contractual lock-up or restriction details beyond the Rule 144 notice.
