Events

• CES 2026 – Las Vegas, NV | January 7–10, 2026
  Memfault will be at CES 2026 connecting with engineering and product teams preparing for 2026 launches. A major theme we’re hearing: teams want fewer surprises once devices hit real customers, and better visibility into crashes, battery behavior, performance, and release quality across their fleets.
  
  We’ll be hosting meetings in the Venetian Tower — Suite 29-223 throughout the week, and running live demos at Nordic Semiconductor’s booth (Venetian Expo, Halls A–D — Booth 52039, Smart Home). If you’re attending CES and want to compare notes, you can book time with the team here.
