The best API integration brought me here, Oli is keeping me here

What made my experience great was Oliver AKA Oli AKA the legend in customer service. He spent hours with me over the last couple months after the migration to FIFO 1099-DA America stuff. Seriously, I really only have super high praise for Oli. In the last year for sure, nobody has even come as close to his persistence in assistance and making sure that I have felt confident and had my questions answered thoroughly. I think candidly Oli is the only reason I'm still with Summ. I've never found better help in the Crypto tax software space. Dudes awesome. Dude needs a raise he handles way more workload than 90% of your customer service department. I'm going on 3+ years using this service.
