Amplitude, Inc.
A maker of product analytics software, Amplitude helps companies track how people actually use their websites and apps, showing which features get used and where users drop off. The company began in 2012 as Sonalight, a voice-to-text Android app, but the founders built their own tool to understand user behavior and pivoted to sell it instead, renaming the company Amplitude in 2014 to reflect the depth of insight it offers. It went public on the Nasdaq exchange in 2021.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -3.97M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
