About Open Solutions (Now Fiserv Portico)

Open Solutions, Inc. was an independent credit union core processing company founded in 1989 and acquired by Fiserv in 2011. Under Fiserv, the platform was rebranded as Fiserv Portico. Many in the industry still search for "Open Solutions" by name — if your credit union runs Open Solutions, you are running Fiserv Portico today. The platform serves 700+ mid-market credit unions across the US.

Formerly independent, now Fiserv Portico — still serving 700+ CUs. Aerial is built to integrate directly with Open Solutions — your core stays exactly as it is, and your members get a modern account opening experience that converts.

Why Account Opening is Hard on Open Solutions

The Open Solutions → Portico transition has meant years of platform consolidation, during which digital channel capabilities lagged competitive platforms
Many Portico/Open Solutions clients operate account opening workflows that were designed for the web era of 2012–2016 — high friction, low mobile conversion
Portico's integration ecosystem is Fiserv-centric, making it harder to bring in best-of-breed point solutions without Fiserv certification

How Aerial Integrates with Open Solutions

If your credit union runs Open Solutions (Fiserv Portico), Aerial connects through Fiserv's Portico API layer. The integration covers member creation, account opening, and initial funding — all executed within Aerial's pre-core verification workflow. Your Fiserv relationship manager can confirm Aerial's compatibility with your specific Portico configuration.
