I would look for people who are influential in your target market and talk with them individually.

Even though your product is based online, it might be beneficial to start with local chamber of commerce networking so you can meet your prospects in person. If your product can capture their attention, keep them close to you and overcommunicate to get their feedback on what they like and don't like and where they get stuck. Help them build the habit of using your SaaS.

Iterate if you need to overcome roadblocks to successfully adopting the software - maybe make training videos, or add documentation, or make changes to the product itself if there's resistance to using some part of it.

What you want to do is really bond those early users to you and find your evangelists who will talk about your product on social media and livestreaming platforms like Periscope and Blab.

Interview the early users on video using Blab or Google Hangouts or use one of the Skype recorders to ask them how they use the product, how it helps them, how it's made their life easier or their business better, and get their permission in writing to add that to your YouTube channel and then share it on your social media channels, paying careful attention to LinkedIn, since that's where you'll find a lot of B2B customers.

Once you've built up about 5 or 6 of those evangelists, start hosting webinars. Splice the YouTube comments into the webinars so attendees can see how people just like them are using your SaaS.

The main thing is to remember to treat people as individuals and not try to lump them into a group, and really do a good job of babysitting and nurturing those early users of your service.

If you'd like some strategies on finding those people and how to reach out to them, please feel free to schedule a call with me.
