New York-based Power, a full-stack credit card issuance service, emerges from stealth with a $16.1M seed and $300M credit facility

Context & Ripple Effects
Power is entering a card-issuing-as-a-service wave that has been building since late 2020, when Unit emerged from stealth with an API for embedding payment cards and checking accounts, followed by Highnote's own stealth exit as a self-declared Marqeta rival and Cardless's Series B for back-ending brand co-branded cards. Most of those players center on debit or program management; Power's differentiator is going full-stack on credit, pairing its $16.1M seed with a $300M credit facility so it can hold the receivables its clients' card programs generate.
That balance-sheet commitment is what separates Power from pure API infrastructure, and it is also why the story has a known ending in this corpus: within about sixteen months, Marqeta moved to buy the company outright.
First-order effects
- Brands and fintechs launching credit card programs get a single vendor for issuance, underwriting, and funding, instead of assembling an issuer-processor plus a warehouse line themselves.
- Marqeta, which Highnote explicitly positioned itself against, now faces a stealth-stage competitor whose $300M facility lets it compete on credit programs Marqeta does not natively fund.
Second-order effects
- Rivals like Highnote and Cardless face pressure to either raise their own credit facilities or partner with balance-sheet providers, because software-only issuing leaves the margin-rich lending layer to someone else.
- Debt investors gain a new channel into embedded finance, as warehouse-style facilities like Power's become the financing instrument behind consumer card startups rather than traditional bank sponsorship alone.
Third-order effects
- The pattern points toward consolidation around platforms that own both the software stack and the capital stack — confirmed when Marqeta agreed to acquire Power for $223M in cash plus a milestone payment, buying the credit capability rather than building it.
- If full-stack issuers keep getting absorbed by processors, the industry structure splits into a few integrated credit-and-debit platforms above a layer of specialized API vendors, with balance sheet access acting as the moat.
The trend: Embedded card issuing is splitting between software-only APIs and full-stack platforms that fund their own credit, with the latter becoming acquisition targets for the former.
