The first thing I did was check if you are an MoR or a front for other payment gateways and quickly realised it is the latter. Please make it an MoR. We have too many digital goods/services payment processors (which I am sure many commenters have already listed) but very very few that are a full blown MoR. I don't mind paying 5%-8% fees for MoR. MoR is the selling point for me. Everything else can easily be achieved with Stripe and some coding. Not MoR. MoR requires a lot of setup but any Startup that can properly pull off an MoR specifically made for creators will take off big time IMHO.
For whatever reason best known to Startups in this space, they actively tend to avoid going the MoR route. Maybe it is the legal hassles of setting one up or complications with handling taxes across multiple regions. I don't know what exactly is the issue but a disruption is required here. I can literally count on my fingers the number of payment processors that are MoR. It is that low.
If you are a Startup that is in the payments space and want to truly reduce burden of Creators then it is not in the fees. It is in providing an MoR. I am honestly surprised to see payment startups fighting to lower fees (which probably isn't a concern for most) rather than innovating on and fixing real pain points of Creators. When I choose a payment processor I don't fixate only on the fees. That is probably my last priority. I have other factors that take precedence (the points are listed in order):
1. Are they an MoR? (If no, I just skip. It doesn't solve my pain point).
2. How do they handle chargebacks?
3. How do they handle scammers who misuse their services?
4. How do they handle Creator accounts? Do they have draconian policies where Creator accounts just get shutdown without proper notices?
5. How flexible is their payment schedule?
6. Do they support Wire transfers for payouts?
7. Pricing
As you can see, Pricing comes at the very bottom of the priorities I have set before choosing my payment processor. It is, in all aspects, a lifetime relationship. Why would I give more importance to pricing if you are solving my pain points? That is worth more than a few percentage points you shave off the price. I want Startups in this space to compete on the 6 points and give the 7th point a lower priority. Only those who are not exposed to this space tend to first go for point 7 but quickly realise they have to deal with taxes and other complex legal stuff and quit your service. You'll just end up having a higher churn rate and not so loyal customers.
Not taking anything away from your launch. Just providing some constructive feedback.
