A maker of handheld chemical detectors, 908 Devices builds tools like the MX908 that soldiers, hazmat teams, and police use to spot explosives, drugs such as fentanyl, and dangerous chemicals on the spot. Founded in Boston in 2012, the company shrank lab-grade mass spectrometry into a pocket-sized device. Its odd name comes from 0.908, the point in a mass spectrometer where founders say "the magic happens"—a fitting symbol for finding answers in unstable moments.

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: -1.64M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
