What Portside does
Portside is a cloud-based SaaS platform serving the business aviation, regional airline, government, and aircraft leasing and finance industries. The company provides an integrated suite of applications covering flight scheduling, charter quoting, crew management, owner billing, safety management, reporting and analytics, and operational optimization—replacing fragmented point solutions with a single data layer across 10,000+ aircraft operated by 1,300+ enterprise customers in 30+ countries. The platform was built through a deliberate roll-up strategy: Portside (founded 2017-2018 in San Francisco) acquired PFM (2022), BART/SeaGil (2023), Stellar Labs FOS Hosting (2023), Avianis from Wheels Up (2023), Baldwin Safety & Compliance (2023), and Takeflite (2024), consolidating the dominant scheduling, safety, and operations brands in private aviation under one umbrella. Portside Horizon, launched February 2025, represents the next-generation consolidation layer built on a cloud-native, modular architecture with Microsoft Power BI analytics.
The business model is enterprise SaaS with quote-based annual subscription pricing, sold through a direct field sales motion and supported by dedicated account managers and customer success teams. Revenue streams include platform subscriptions and licensing of acquired products. Pricing is opaque and scales with operator size, fleet count, and module selection; deal precedent includes 10-year enterprise agreements (e.g., Solairus Aviation). The company is majority-owned by Vista Equity Partners following investments in 2024 and March 2026, with Insight Partners remaining a significant shareholder from the $50M Series B (February 2023); Tiger Global led the $17M Series A (May 2021). In March 2026, Brandon Holden (former Eptura CEO) was appointed CEO to lead the next phase of AI-enabled platform integration and global GTM scaling.
