The Reston-based satellite communications company is in the process of going public via a SPAC deal with NavSight Holdings.
Yaffe will handle communications across Spire’s business units, which include federal, maritime, weather, aviation, Earth intelligence and space services.
She will report to CEO Peter Platzer and be based in New York.
Most recently, Yaffe was senior VP and head of communications at Lazard Asset Management.
Platzer said Yaffe’s communications experience across multiple industries, as well as the capital markets, will be an invaluable asset for the company.
Spire provides comprehensive data and analytics to clients from offices in San Francisco, Boulder, Glasgow, Luxembourg and Singapore.
