We’ve tried them all, so you don’t have to

After integrating various aggregators, we realized what we needed most: simplicity, reliability, and precision.

So, we built our own. It's straightforward, supportive, and accurate — exactly what you're looking for.

Reliable bank

Beautiful UX

You spend time and money optimizing your user signup flow. Ensure your bank connection flow is just as effective at activating your end users. Aerosync was built with hundreds of hours of research from Aeropay and the Financial Data Exchange (FDX) to craft the easiest way to safely and securely link a bank account.

Reliable Data

Aerosync dynamically checks to ensure that a full account number is being returned rather than bad data which may result in costly returns.

Instant Fallback

In a world where things move fast, spending two days to wait for microdeposits to hit your end user's account is too slow. With Aerosync you can do manual bank linking with an account and routing number in seconds. We also name match the user's name with the bank account for extra security.


Ensure that your end users are able to only add accounts that support account-to-account money movement. By only allowing checking accounts, you can ensure that your end users send funds from a supported account type.


ACH returns cost money, which means having an aggregator with built-in safeguards can help reduce your risk exposure. No need to worry about ACH returns from neobanks that allow overdrafts.

Your branding, at the forefront

Enhance your brand's identity by customizing payments with your logo and color scheme.

Boost customer engagement and adoption through targeted marketing of your payment solutions.

Trusted by thousands of innovative businesses

We love Aerosync. Its suite of tools have allowed PrizePicks to greatly increase customer conversions while simultaneously lowering costs on ACH returns and bad data.
