      eCommerce Review from Anonymous

      Right after launching our campaigns with Disruptive, we saw results almost instantly. Our monthly revenue jumped from about $50,000 to over $70,000. Every key Google Ads metric improved, and by November, we were already nearing $550,000 in revenue, well on track to hit our $700,000 annual goal.
