Outreach angles
- -Arcjet embeds security directly into application code rather than sitting as a perimeter layer, targeting the developer-first security trend that has gained traction since Snyk's rise.
- -The $8.3M Series A for a San Francisco-based cybersecurity startup positions Arcjet to hire engineering talent and expand its SDK integrations across major frameworks.
- -By making security a code-level concern, Arcjet competes in the increasingly crowded AppSec space but with a differentiated distribution strategy through developer adoption.
