Do you mind sharing what kind of Saas are you thinking of? Who will your customers be?

Unless your Saas requires high-touch sales, the number of leads you are able to reach will increase as your business grows. In the beginning you might be talking to 10 people per day personally, and down the road - your blog/integrations/PR/referrals may bring in dozens or hundreds of leads per day. It's rare for the number of leads to be constant across a lifetime of your business. Similar to a rolling snowball, all your lead-gathering efforts will build up and hopefully produce growing results.
