Where can I look this type of data up? (for free)

Lots of hullabaloo out there regarding SaaS multiples. I'm hearing anything from 5 - 20x. I want to see some actual data.

I looked at BVR but it didn't look like they segmented multiples by EBITDA size? - that's the level i want to drill down into

much obliged to anyone who can help with this!
