My in-house affiliate program is providing $25 EPC and need new software to scale ASAP!

My company's affiliate program is growing quite fast. It's an in-house affiliate program for our marketplace of 50+ trading and investing products. The products are what we call "user-generated" because our platform allows for experts to come on and build their own education courses, trading strategies, etc. and then sell them on our marketplace. At the moment it's still private invite to build a course so we can hit critical mass of quality products.

We already have several thousand users who have bought or subscribed to a product and we've reached over 25,000 people with our education webinars.

I've built up a great in-house affiliate program and I'm at the point where I need a more reliable and robust system to run the entire program. With an EPC well above $25 and a recent investment from a venture capital company, I need to make sure whatever I switch to is the right decision. With the momentum we have, I can't afford to have to switch again.

I'm looking at HasOffers, DirectTrack, and a couple others to run the program on.

Does anyone have any experience running their affiliate program with one of these providers?

Does anyone have any experience being an affiliate for a company that uses one?

Any feedback would be HUGE!!
