About Us

Nexus Weather & Climate is the Weather Decision Platform. We provide customized site-specific weather intelligence for teams whose operations are directly impacted by weather. Rather than asking teams to interpret a general forecast on their own, the Nexus platform helps teams understand when, where, and how weather could affect their specific assets and operations. We support businesses across aviation, hospitality, marine, municipalities, transportation, and more.

• Renewal Ownership: Own the renewal calendar across all accounts; initiate renewal conversations with sufficient lead time.
• Expansion: Identify and qualify expansion opportunities and carry them through to close.
