What's a good way to attract customers when the most effective marketing strategy is plain word of mouth?

Cash money should be treated separately than sweat equity. There are practical reasons for this namely that sweat equity should always be granted in conjunction with a vesting agreement (standard in tech is 4 year but in other sectors, 3 is often the standard) but that cash money should not be subjected to vesting. Typically, if you're at the idea stage, the valuation of the actual cash going in (again for software) is anywhere between $300,000 and $1m (pre-money). If you're operating in any other type of industry, valuations would be much lower at the earliest stage. The best way to calculate sweat equity (in my experience) is to use this calculator as a guide: http://foundrs.com/. If you message me privately (via Clarity) with some more info on what the business is, I can tell you whether I would be helpful to you in a call.

NIcole is right. When I first started my business I thought I was saving money by doing my own bookkeeping. It took me much longer than it would take a bookkeeper - all time that I was not spending on marketing or billable activities. And in the end I made errors which made the initial work of the bookkeeper longer. I now have a consistent routine. My bookkeeper picks up all my material monthly and does my books in less than 2 hours. Very worthwhile.

Build a body of work in the form of a blog. Much depends on the size and scope of your company, but branded journalism can really make a huge difference.....

I would suggest the first question to ask is "what problem do I solve?" And of those people I solve problems for "who do I create the most value for?" In the non-profit world you need to add "How does my business help the non-profit run better and/or help the group the non-profit focuses on?" For example, if you've created a platform that drives donations, your company "has created a platform that helps you reach fundraising goals faster." What you don't want to do is market and sell to B2B and B2C audiences simultaneously. They have different ways of buying - a B2B audience needs to have their benefits quantified (using your thing makes me x amount more) - and it's extremely hard for a startup to be able to do both well. Better to start with one, execute really well and move into the other. Feel free to give me a call and we can dig into who your most valuable audience is.

I'm answering your question assuming that you hope to be able to replicate it's own success in your own mobile app. There are a couple of factors responsible for it's growth that are instructive to anyone building a mobile app. "Leveraging the intimacy and privacy of the mobile phone." We now have an *intimate* relationship with our phone like no other device in the history of technology. Every internet company that started before around 2010 has built their core interactions around "the old web" one which was accessed primarily via a browser on a computer. Companies that start with a clean slate, should be building their interactions around how to do whatever the app is supposed to do while leveraging what is unique to people's relationship to their mobile devices. Photo-sharing has become a core part of the way we communicate now. Snapchat built something that provided an experience that leveraged the feeling of privacy and intimacy that is unique to mobile. "Provided an escape from the "maturity" of other online services." Too many parents, aunts, uncles and other "old people" have encroached into the social networks of teens and young people. As a result, they've had a desire to find places to express themselves in places inaccessible by older generations. An important distinction is that it's not just parents and relatives that young people are trying to avoid, but also employers & colleges who are increasingly using "mature" social networks to review applicants. "Leveraged PR even bad PR" The fact that the app got so much press about it being used to sext was perfect PR for the company, as it essentially reinforced the brand experience that it has today. Essentially, "if it's safe enough to send a sext, it's safe for any kind of communication I want to have." And although the safety and security of Snapchat is actually not as advertised, it still enjoys the reputation of having less impact than any primarily web-based service. Building a successful mobile application is one of the hardest challenges to face designers, programmers and entrepreneurs in the history of writing software. Happy to talk to you if you're considering building a mobile app, about what I've learned about the "table stakes" for success.
