. Online Presence - Needless to say, that every start-up would need a website. And you should strictly avoid using free web hosting sites. Spend money in buying the domain name & space. If you are familiar with website design or DIY website platforms, you can save some money but make sure the site has the professional user experience. A web site is the online face of your start-up, and hence you shouldn't shy away from spending a few bucks if need be. Apart from having a good website, you should have the right email, web-meetings and social presence. While one can argue that all of these can be picked up for free or freemium, IMO it is worthwhile spending some money in buying the domain, space, email address, online conference & communication services, mobile platform (if need be) and digital marketing.
