The Detroit, Mich.-based online-only bank, Ally Financial, had 120,000 new deposit customers in the first quarter on 2019, CEO Jeff Brown said on the bank’s 1Q earnings call Thursday, bringing the Ally’s total depositor count to 1.77 million — a 20% YoY increase. CFO Jennifer LaClair said new customers accounted for 56% of Ally’s balance growth, and that millennials represented 59% of new account openings.

Millennials accounted for 55% of new deposit customers in all of 2018, Bank Innovation previously reported.

The 1Q report said Ally had more than $113 billion in deposit balances, an increase of nearly $16 billion year-over-year. LaClair also said Ally is now 70% deposit-funded and expects to “steadily move” to 75%-80% over time.

On digital trends, Brown said:

“Appetite for direct digital banking products continues to grow as consumers prioritize products with greater value and increased utility, elevated service levels, and high transparency and convenience. Digital deposits meet many of these criteria and have continued to grow, and still represent less than 10% of the retail deposit market share today, a nice path forward, given our industry-leading position and value proposition.”

Brown touted gains made by Ally Home, a direct-to-consumer mortgage offering, through which originations of $400 million were the strongest levels seen since Ally launched the offering in late 2016.

He also announced Ally is partnering with Better.com to launch a digital mortgage platform. Through the partnership, he said Ally customers will be able to complete an application and obtain pre-approval in under three minutes and lock in a rate in under 10 minutes.

In addition to the partnership, strategic-investment arm Ally Ventures will make an add-on investment in Better.com’s recent Series C funding, significantly increasing Ally’s overall ownership in the company. Better.com in January had secured $70 million in a round led by American Express Ventures and the Healthcare of Ontario Pension, with participation from existing investors Kleiner Perkins, Goldman Sachs and Pine Brook.

The companies said the new capabilities will be piloted in nine states this summer: Arizona, Connecticut, Louisiana, North Carolina, Oregon, Pennsylvania, Tennessee, Texas and Washington. By the end of this year, the services will available nationwide.

Ally has a market cap of $11.9 billion. Better.com has raised a total of $120 million, according to Crunchbase.
