It is almost impossible to know exactly how long a sales rep pitches a product or exactly what they said, and this makes it difficult for businesses to improve their sales. Siro provides a digital mobile and desktop app that facilitates the tracking and analysis of the conversations of sales reps and clients. The app records and transcribes sales conversations, providing a quantifiable footprint of every sales conversation which can then be analyzed by sales managers for improvements. Whilst the recording and transcription software behind Siro is nothing new, the integrated approach to tracking sales conversations is one that has been untapped until now. The company claims that when used properly, its sales coaching system can reduce sales conversation time tenfold - giving Siro the potential to take sales coaching to a whole new level.
