When will I be able to use Clarity to call potential customers? Because what they think matters most

At WP Engine, everything in marketing and sales is included in CAC. Salaries, commissions, coupons, direct advert spend (which you're saying you don't yet have), fees, travel and other costs associated with conferences, etc.. My advice is to err on the side of putting too much in CAC, because that helps you honestly understand the costs. Ignoring some costs just because they don't scale with company size or marginal new customers doesn't make sense to me, it simply means that certain components of your CAC you expect to get more efficient over time. Indeed, they had better! So measure it, instead of ignoring it. You also might find that some of those direct-spend channels are not as inefficient as they seem compared to things like SEO efforts. Or the reverse! All good things to explore of course. I'll also note that at $19/mo in the crowded space of CMS offerings you will find that very few channels will be efficient compared to the revenue you're generating. It sounds like you know that, and are dealing with it with "scalable" efforts like content marketing, however again you should be ruthless in understanding how those costs are really translating into orders and whether that's a financially sensible total strategy.

To answer this, you need to have a working model for your customer LTV (Life Time Value). Most startups can't accurately estimate their LTV, so if you don't have good enough data, then building your CAC based on assumed LTV numbers can be fatal. In this case, it's better to evaluate your CAC costs based on the months of revenue it takes to recover the cost to acquire the customer, and ultimately this calculation should be net of any costs associated with providing the service on a monthly basis and, even more conservatively allow for a healthy degree of churn. Keep in mind that this calculation doesn't evaluate your true profitability only the capital efficiency of your customer acquisition spend. Hope this helps. Happy to talk this through in more detail and with more specifics to your business.

Lot of ways 1. Target their fans on facebook - if they are big (20k+) you should be able to select them as an interest 2. Bid on the same keywords as them on adwords search and/or display - this requires some technical chops but there are ways to find your competition's placements. If you can get there and present a better ad and/or outbid them, you can get the clicks they are used to getting. 3. Find where their customers are spending time online - another thing that will take some chops but you can find out what blogs, facebook pages, etc your competition's fans are looking at and get in front of them there. This is an indirect method. Most of the other options you will have are some variation on that theme. Make sure you have a way to stay in front of them (like retargeting or email marketing) if you want to make your investment go as far as possible! Good luck

Did you know that having an fancy expensive website doesn't do it either...I mean you can pour thousands of dollars into a website... but without traffic, it wont be worth it... Find you target demographic.. Schools, Community Centers etc... and go old school... HANG UP A FLYER!.... that will get you going... if your product is awesome... the organic word to mouth method will get you students... So two things.... do not be afraid to go OLD SCHOOL... and be sure that your product is of quality...

Find apps that are B2B and go to the review sections. Specifically going to Google's play or Chrome store and look at reviews and follow them to Google+ to engage. I took that same angle for B2C app I was building last year. Check it out. http://blendah.com/post/37331434653/lean-startup-hack
