The third annual Power Partner Award is presented by Inc., the leading media brand and playbook for the entrepreneurs and business leaders shaping our future, honoring B2B organizations across the country that have proven track records for supporting entrepreneurs and helping startups grow. Apollo is proud to be recognized as one of the best B2B providers in the CRM - Sales Force Automation category, helping small and medium-sized businesses (SMBs) manage customer data, track customer interactions, compile business information, and automate sales. Apollo is featured alongside 359 other highly acclaimed business leaders, including Pipedrive, Slack, and HubSpot. The Power Partner Award recognizes the highest caliber of B2B partners who support entrepreneurs in critical business areas, such as hiring, compliance, infrastructure development, cloud migration, and fundraising. This frees up founders to focus on their core missions. Inc.'s methodology includes anonymous client surveys and qualitative ratings, online sentiment analysis from Inc.'s data partner, Meltwater, and research and analysis of data by Inc. reporters. Every company on the Inc. Power Partner award list received top marks from clients for being instrumental in helping leadership navigate the dynamic world of startups. "This is our definitive listing of vendors and suppliers who have demonstrated excellence in serving small- and midsize customers," says Inc. editor in chief Mike Hofman. "As part of the vetting process, our team of editors, researchers and reporters gathered information on companies' products and services, assessed their reputation as captured in online comments and forums, and collected customer testimonials to ensure that the sales pitch matches the actual client experience. In every case, we spoke to founders like you who were happy to attest to a vendor's genuine commitment to a mutually beneficial business partnership. We're happy to be the conduit for that positive word of mouth."
