The verdict
Start from the question you are trying to answer. If it is which companies are looking at us, I'd pick Albacross. If it is how do we run and pay a partner programme that already brings in revenue, I'd pick Trackdesk.
For a small B2B team that has a target account list and steady traffic, Albacross is the more likely fit. Trackdesk only makes sense once partners already bring meaningful revenue. For a first affiliate test, it is too much, and something lighter is a better start.
If you honestly need both, they do not overlap, so you can add the second later.
