to expand on this, i'll trot out my little adage again: most startups are marketing problems, not technology problems.

marketing encompasses the 4 P's: product, price, promotion and place. product is literally the finding of the fit between your offering and the market's needs. price is the portion of the value you deliver to the customer that you capture. promotion is finding and providing potential customers with info about why your product is the shizzle. place is how you deliver the product to your customer (e.g., physical store, direct sales, saas, app store, etc.).

build things that support your marketing activities, rather than building tech that you hope you can market.
