Alphabet’s CapitalG leads $40 million round in fintech Mantl Community banks and credit unions aim to be the heart of the, well, communities, they serve. But without the big budgets of larger institutions, keeping up technology-wise can be a challenge. And not only are they competing with legacy players, there is also a slew of digital banks that have emerged in recent years, as well.

Founded in 2016, New York-based Mantl has been described by some as “the Shopify of account opening.”
