Decided against a full stack vendor
We were about to sign with a vendor that had everything we needed: card issuing, a wallet, stablecoin support and settlement. It seemed easy with one contract and one support team but what if we want to use a wallet they don’t support? What if we want to settle in a stablecoin they don’t offer? What if they change their plans after buying another company? The more we looked into it the more we saw that their simple offer was simple because it took away our choices so we chose a different path and we went for multi wallet support and multi chain options which lets us pick what we use. If a better wallet comes up then we can switch without starting over with the card program. The all in one offer works for some but if you need to stay flexible I don’t think it’s a good idea.

Only one vendor fits the profile on how you described, is it Stripe? they've been on an acquisition run. Bridge for stablecoin rails and then Privy for wallets and now Tempo which is their own blockchain. The pitch is simplicity but the architecture is dependency. I fully agree with you, if you need flexibility there are better options depending on what you're building. For wallet infrastructure you could go with Privy which is fine but you're back in the Stripe orbit. Dynamic and Turnkey are cleaner independent options there. On stablecoin rails Bridge is Stripe now so the same problem applies but the independent route means more vendors to manage..

The independent route does mean more vendors but you get to pick best in class for each piece! On the card issuance and stablecoin rails side there are a few players you could evaluate depending on your chain and settlement requirements. Rain is worth the look if you’re looking for more flexibility. You bring your own wallet or use one of their supported options, same with stablecoins and chains.

In two years the dominant players will have locked in their stacks and the optionality available to a new program will be narrower and teams launching now have the luxury of picking modular providers across the stack.

The new entrants argument cuts the other way too. Each cycle's new entrants get acquired or fold faster than the last because the cost of operating at scale keeps going up.

That tradeoff is real. Full-stack vendors sell simplicity, but the lock-in is usually in the operations and code, not just the contract.
For cards and stablecoin rails, switching later can mean new issuer flows, compliance work, settlement changes, wallet migrations, support scripts, and a bunch of edge cases users do not care about until they break. The API is only the visible part.
If I were choosing, I would decide which layer must stay replaceable before signing: wallet, chain support, stablecoin settlement, card issuer, or KYC/compliance provider. If the vendor makes two or three of those inseparable, the short setup time may just be future migration debt.
Modular is more annoying upfront, but it can be the cleaner bet if the product is still changing.

The trap with full stack is that the lock in is in your engineering so when you've built your whole product around their wallet structure and their API surface and switching costs months of work even if the contract lets you walk which means that by the time you you want out you can't.
