01 // LEGACY TREASURY BOTTLENECK

Prior to onboarding with Vanguard Signal, Aether Cloud held $42M across 7 commercial checking and regional sweep accounts earning a blended 0.40% APY, while their accounting team spent 6 days each month reconciling bank statements manually.

02 // 90-DAY VANGUARD ARCHITECTURE

Within 14 days, we opened a direct-titled BNY Mellon Pershing custody vault, swept $34M into a staggered 30/60/90-day U.S. Treasury Bill ladder yielding 5.28% APY (100% exempt from state corporate income tax), and kept $8M in an instant T+0 operating sweep linked to NetSuite.

03 // AUDITED BOARDROOM OUTCOME

Aether Cloud generated $1,424,000 in net additional risk-free cash income in year one, reduced uninsured deposit exposure to $0, and cut monthly treasury close time by 92%.

“Vanguard Signal turned our dormant operating reserves into $1.42M of state-tax-exempt Treasury income—covering 11 senior engineering hires without touching principal.”
