Erebor National Bank Charter Model
$112M/year Hereticon of nationally chartered banks
The real strategic move was not starting another startup bank, it was owning the bank charter so no outside sponsor bank could freeze product launches, force migrations, or sit between Erebor and its customers. That makes Erebor look less like a software wrapper on bank accounts and more like Column, where the charter, ledger, compliance stack, payments rails, and APIs live inside one regulated entity. It also fits the post SVB and post Evolve world, where fintech dependence on partner banks became a direct product and existential risk.

Column is the clearest template. It owns a national bank charter and rebuilt the tech stack around it, so fintechs can plug into one bank that both holds deposits and exposes APIs. Erebor is applying that same integrated model to defense, AI, and crypto customers, with stablecoin and specialized underwriting layered on top.
-
The upstream partner problem became concrete in 2024 and 2025. Mercury disclosed that it was moving customers away from Evolve, while regulators restricted Evolve from adding new fintech programs without approval. That showed how a fintech can have customer demand but still be constrained by a partner bank's compliance and supervisory problems.
-
A national charter also changes how money flows. Instead of sharing economics with a sponsor bank and middleware layer, Erebor can keep more of the spread on deposits, lending, payments, and API services. That is why vertically integrated banks like Column and Lead Bank have become the preferred backbone for fintech and stablecoin programs.
Going forward, more fintechs and sector specific banks will try to collapse the stack in the same way. The winners will be the institutions that combine a real charter, modern APIs, and a risk program strong enough to satisfy regulators while still shipping products quickly. Erebor is positioning itself to be that bank for higher sensitivity industries that do not want infrastructure dependency.
