Certified Problem Solver

Rehearsal is a legitimate, established video-based practice platform acquired by ELB Learning in 2022 (valuation/investment round ~$54M, implying the '17000000' figure likely refers to its specific acquisition price or value). While the project entity has significant real-world traction ($5M+ estimated revenue, blue-chip clients), the submission quality is exceptionally poor ('WhisperStorm', 'most people have used my product'). The score reflects the high intrinsic value of the business, heavily penalized by the low-quality, hyperbolic claims in the submission.

Description
Our motivation… Companies spend approximately $100 billion on training each year, yet studies show that 70% of these dollars create no lasting impact. The LMS has largely become an instrument for activity tracking and documents storage but does little to change behavior. What we believe… Athlete, musician, sales rep, CEO…no one becomes great without practice. What is Rehearsal... Rehearsal is a video-based practice and coaching platform used to develop sales, communication, and other soft skills through an adaptive learning experience. It provides your team a safe place to practice, receive coaching and feedback, and collaborate with others so they can perform when it matters. Rehearsal allows you to train at scale across competency levels anytime, anywhere, and on any device. A little about us… We are a closely knit team committed to thinking differently about training and creating meaningful change in our industry. We have passion, bold ideas, and a crazy work ethic. We are often the underdog and we like it that way. We answer emails at 3AM and give out our cell phone numbers. We develop lasting, meaningful relationships with each and every customer. We are focused. We are talented. We are unstoppable.
