49% of respondents who had not participated in an accelerator reported that customer contacts would be very desirable. However, only 22% of the participants reported that the industry contacts provided by the accelerator had been excellent. 46% reported these to have been "neutral" or "poor". The open-ended answers support this, with many founders pointing out that an accelerator would add the most value by providing partner or customer contacts. "Industry fit" was also mentioned as an important criteria for selecting an accelerator program.
