In a physical channel, you have to initially create a demand for your product through some of the mechanisms mentioned in the last task.

You're guiding your customers through different stages of your sales process (not necessarily the exact ones shown in the diagram) towards the ultimate goal of them purchasing your product or service.

A viral loop is a simple multiplier effect (that difficult to create), but maximizes the amount of people that know about your product. Don't worry if you can't add a viral loop to your startup - sometimes it can't be done.

Remember, it's much more expensive to get a customer than it is to keep one. So make sure you spend time thinking about how you can keep more of your customers and gain a higher lifetime value (LTV) from each users.

Keep them engaged with your brand through: loyalty programs, newsletter, product updates, recognition and customer service.

The next phase is growing your customers. Can you increase the dollar value of each customer? Can you upset to each of them by unbundling the various features of your product? Things like discounts, upgrades, credits, and referrals/affiliate programs may help your startup.
