I work at a small (10 person), sport-specific e-learning startup. The CEO is a nice guy but I feel he lacks focus. He is very easily excitable, so if he or somebody else comes up with an idea that he likes he will often become fixated with it for a week or two before completely forgetting about it. These ideas are most often spur of the moment with no research to back them up and range from the unrealistic to the ridiculous.
As the sole designer, I am often the first port of call when he wants to visualise these ideas. I've spent countless days thinking about, designing and delivering mockups - often with very little to go on other than 'our users really want this' with no real data to suggest they do. Quite often in meetings with potential customers he'll drop 'we can get it mocked up for you' to appease the client. 9/10 nothing ever comes of the work I put in as by that point he's got bored and moved onto the next 'must have' idea.
He's recently had a meeting with someone who suggested that our platform would work well for a different sport to what we specialise in. Technically, our platform could be altered to cater for different sports, however I feel like our small team already has more than enough on our plate. He's asked me to mock something up despite the fact that he's done literally zero research himself, and the only asset he can give me is a logo and a few sentences briefly summarising the conversation. If I were to liken the situation to that of another company, I'd say it would be like Uber offering boats as well as cars (I understand they do offer this service in certain countries, but you could argue that they nailed the core car offering first before pursuing other modes of transport).
I really want to tell him to stop chasing these leads as they never materialise into anything positive and distract our already busy team from improving our current platform (which needs a lot of improving). One of the mantras that respected CEO of Huit Denim lives by is to 'Do One Thing Well', but I feel like this is the opposite of how this CEO runs his company. Am I being unreasonable?
