About the company

Vega is building the distribution operating system (“AltOS”) for the alternatives industry, empowering asset managers to efficiently service and scale their client base in an era of hypergrowth for alternatives.

Through a single unified Core engine, Vega orchestrates previously siloed offline processes across pre-trade, execution and post-trade client operations, while enabling asset managers to distribute their products through a scalable “Alternatives-as-a-Service” framework. Vega’s modular, API-driven architecture ensures compatibility with a broad range of existing point solutions and third party stakeholders, setting the foundations for the first purpose-built infrastructure layer for the alternatives industry.

Vega's founding team consists of alternatives specialists from investment firms such as KKR, Blackstone, Elliott and Goldman Sachs, along with top product and engineering talent from successful fintech scale-ups like Revolut and Trade Republic. Vega has raised over $28m in funding from Apollo, Motive Ventures, Picus Capital, Citi Ventures, and 60 senior executives from the alternative investment industry.
