Governance Assessment

  • Alignment and effectiveness: Committee assignments match expertise—Audit (financial controls/risk oversight) and Cybersecurity Risk Management (information/cyber/product security), reinforcing domain-driven oversight . Board independence affirmed; Audit Committee independence and oversight responsibilities are robust .
  • Attendance and engagement: Board met 11 times in 2024; all directors met ≥75% attendance requirement and attended the annual meeting—supportive of active engagement .
  • Compensation and ownership alignment: Director pay is equity-heavy (annual $200k RSUs time-vesting) with modest cash retainers/committee fees; directors must meet stock ownership guidelines (≥5x retainer), and all non-employee directors were in compliance—positive alignment and risk mitigation .
  • Controls and conflicts: Hedging and pledging prohibitions and formal related-party transaction policy (Audit Committee review) reduce misalignment/conflict risk; no related-person transactions disclosed involving Tosheff . Note board-level interlock via Syn Ventures (Coviello as Managing Partner; Tosheff as Venture Partner); independence affirmations mitigate but warrant monitoring for perceived conflicts .
  • Compensation governance environment: Compensation Committee uses independent consultant (Compensia); no consultant conflicts noted; clawback policy adopted in Nov 2023 per SEC/Nasdaq requirements—strong governance hygiene .
