It looks like a spin-off from leetchi.com [1] crowdfunding site.

My impression is that the mangopay itself is also more geared towards group-buy etc ventures.

If they do not provide a credit card vault that you can take to another payment company as needed then It's a high-risk option. Just like any other payments company without a vault. Vault is not an issue if the customers making one-time purchases and there's no recurring subscription.

If your biz is with recurring billing then you don't want to run parallel payment systems or ask users to resubscribe whenever there's a need to move somewhere else.

I'm in EU as well and things do not look good for small startups with a need for recurring "mutable" payments. The only reliable option is braintreepayments but 100eur minimum is high and there's an uncertainty with the pricing because of the rumors on Paypal/eBay takeover.

I'm waiting for Stripe to expand to all EU countries. PayMill is very similar to Stripe but their biggest problem for me is not having the vault -- I would not be able to transfer my subscriptions to a new provider if needed (AFAIK, please prove me wrong).

Thankfully I don't require recurring payments for this project, so this would not be a show stopper for me.

Have you seen any other reputable provider that does not levy chargeback fees?

I'm afraid all reputable providers have chargeback fees.

That's something banks charge from the merchant [1] so it doesn't make sense for the provider to take that risk. Provider does add a bit of extra to cover their side of the work, no idea how much.

Sorry, I haven't made myself clear - I meant that question in terms of "this is too good to be true, right?".

Ah no, my English sucks, had no idea what "does not levy" meant :)
