What are your recommendations to have an impact with partnerships when it comes to revenue in the first 6 months?

Be very willing to be wrong. "Strong opinions, loosely held" is a great mantra for partner leaders in an early-stage programme. In my most recent role, there was a single reseller partner that had driven 25% of new revenue in the previous 12 months. My first thought was "find their competitors and this will be easy! Speak to their top 8 competitors, and even if you only successfully activate one or two, you'll have doubled or even tripled the partner revenue!". In the two years after joining the company, we drove $0 in new revenue from any reseller partners, including the one I inherited. My initial hypothesis was very wrong, but by staying relentlessly focused on short term outcomes I was able to discover other avenues for partnerships; including a new cornerstone partner. Partnerships contributed 42% of new revenue for the financial year and more than half of that came from this one critical partner. If I had stuck to the (seemingly sound) logic of investing time and effort into replicating what had already worked, we would've completely missed that opportunity, drove 0 new clients, and I'm sure I wouldn't have been asked to stick around for very long!!
