Fintech startup Plaid secretly powers your mortgage while preserving data privacy


UPDATE: Visa agreed to buy Plaid in January 2019 for $5.3 billion, 2x it’s late-2018 valuation. This renews Plaid data privacy credibility.


We need to revisit a story that slipped past during the holiday rush. It’s about a fintech company called Plaid that powers everything you do with your financial life. But it’s all behind the scenes, so let’s take a look at what they do and whether they’re preserving your data privacy.

Plaid raised a $250 million Series C round of venture capital this month, valuing them at $2.65 billion.

They were founded in 2012 to be the plumbing for how countless consumer finance companies like Venmo, Robinhood, Stripe, Acorns, and Marcus (Goldman Sachs) connect to banks.

Use Betterment to invest your money? Coinbase to trade crypto? Moneylion to manage your budget? Plaid connects them all to your bank, and they do this for tens of millions of you.

Plaid is equally ubiquitous in the mortgage industry. When you apply for a mortgage and get asked to connect your bank accounts to verify your income, assets, and transactions, Plaid is increasingly powering this for lenders.

There are other strong players like Yodlee, Finicity, and FormFree. But Plaid is the golden child right now, and their new war chest allows them to build out more of these lender features.

Because of bank data privacy rules, this stuff if harder than it looks.

Plaid’s massive capital raise may help them pull ahead of competitors in giving you an easier — and secure — experience with mortgages.

And even if you don’t know of them, you data is passing through their pipes, so here are a few notes on why it matters to you:


In short, No. You’re not Plaid’s customer so your data just passes through their pipes to get to the lender you choose who then owns your data per your consent. That lender is who pays Plaid for a toolset that makes the lender’s process easier for you.

Lenders also use other tech companies that pay Plaid. For example, many lenders use a tech company called Blend to power your loan application process. Blend uses Plaid to run part of the mortgage app requiring bank account connections (as noted above).

But even in the example of you using a lender that uses Blend (and therefore also Plaid), you wouldn’t really see Blend or Plaid. Your experience would simply be managing your loan process on your chosen lender’s digital mortgage app that happens to be powered by Blend and Plaid. And you’re authorizing the data to pass through Blend and Plaid to get to your lender.

Your relationship and your data resides with your chosen lender.


To approve you for a mortgage, all lenders must verify bank accounts, balances, and transactions from all banks you work with.

So if you’re getting a mortgage from Bank A but have other checking, savings, and investment accounts with Bank B, Bank C, and Bank D, then Bank A will require you to verify those other accounts with them. If Bank A’s loan application uses Plaid (directly or via another vendor like Blend), their loan application will simply prompt you to direct-connect Banks B, C and D and the data is piped over with your consent. Bank A only sees the other banks’ data needed to make a loan approval decision, and has zero control of your accounts at those other banks.

And there is typically a time limit around 60 days where this access is given.


Since Plaid is helping your lender make and maintain bank connections that enable your lender to make a fast loan decision for you, we can expect that you may be asked for permission to maintain these connections for more than 60 days in the future.

Plaid data privacy vision aligns with consumers on this: consumers should own their data.

But if the lender is providing the data connections (using Plaid), and not Plaid itself, the lender “owns” your data.

So there are still bugs to work out.

However if lenders could connect longer than 60 days, they’d get an ongoing lens on your financial situation. This would let them make you extremely relevant offers based on what’s going on in your life at any given time.

Therefore I think we can also expect Plaid and others to, with your consent, help lenders analyze your data so that the lender you’ve chosen and authorized to keep your data can make you these extremely relevant offers instead of sending you evergreen marketing spam with recipes and home cleaning tips.
