There’s a fine line between good sales reps and great ones. Luckily, you no longer have to rely on instinct to figure out the difference. Machine learning can help you to analyze your sales team in the field through detailed customer call analysis. Whether you want to tighten your sales pitch or understand your clients better, machine learning systems can spot the verbal clues that prove the difference between losing and closing a deal.

To perform this kind of call analysis, accurately tagged audio is crucial. A clean and accurately labeled dataset is the bedrock of all great analysis, so you need a partner you can trust to provide you with a solid foundation. Our team of experts work tirelessly to ensure that your system of tags is comprehensive and suited to your unique analytical needs. Whether you’re looking to perform your own analysis or build a conversational intelligence solution to improve sales reps, we have the tools to transform your team.
