One thing that frustrates me is some folks’ inability to understand cost and value. There have been a few times over my last decade of consulting when that inability manifests itself in a particularly bad way. 
I’ve begun work with clients on more that one occasion where the client has spent a lot (in one case, close to a million dollars) of their seed money to build websites that didn’t accomplish what the client needed them to do. Most of the reason for this was that they hired the lowest-cost option. They failed to see that the value they needed was in their provider understanding the client’s business and delivering a solution that met the business requirements. Instead, they hired someone who made them a beautiful website that was fairly useless from a business perspective. That’s cost vs. value. They saved on cost and failed on value.
Startup companies are notoriously short of funds. Often the founders are working without pay and the thought of paying consultants, lawyers, accountants, and other professionals is anathema to them. That’s a big mistake. I worked with another startup that took intellectual property advice from “a friend who had done this before” instead of a lawyer. I noticed a potential problem with their name immediately but they were happy to go with their friend’s advice despite my asking about a legal opinion. As a result, once they launched their brand, they received a cease and desist letter informing them that they were infringing on another trademark. That resulted in a major depletion of their remaining funds to rebrand and to pay a lawyer to respond to the C&D. Cost vs. value in action.
What’s my point? If you’re venturing onto new grounds, hire some guides before you get lost. You’re going to be paying these professionals at some point and you might as well do so early on. Yes, it’s a cost you don’t think you can afford, but the value you receive can prevent very expensive mistakes and will ultimately save you money in the long run. Had I or any reasonably smart consultant been involved early, we would have talked about what analytics we needed from the website to make actionable business decisions before we worried about anything else. Every dollar spent on the site afterward would advance the business’ goals and not to making art rather than commerce.
Pay us now or pay us later. I think the sooner the better. You?

So true. I recently met with a potential client who had someone design them a beautiful site, but the functionality and scalability were lacking. Now they are stuck because they don’t have the additional funds to build what they need. I wish I’d met them at the beginning.
