We target companies with 10-100 employees using a 14-day trial, self sign up model with pricing at $5/user/month.
I would encourage to do pre-trial gamified engagement with target companies/employees. Create indirect yet relevant functional experience and rewards those users with something encouraging. It can be a coffee mug, T-shirt or even a month free for product. Then introduce the SaaS software to use.
Pre-trial engagement gamification can be as simple as - Q & A or Take a photo moment or Mention a problem (one your SaaS software can solve) via tweet.
I have given this method a try and seen very valuable results. Indirect relevance in gamification can be extremely helpful.
We solve this problem with our platform http://oly.io
I am a call /email away if you need further help.
All the good luck!
Best,
Shail
