The better question may be why can't you find startup co-founders? I can see two main reasons why this might be the case. First, no one else sees the same opportunity. If this is the case, you may be on to unique value that no one understands, but that could also include the potential market. If no one else sees the same market opportunity you do in your startup, you will want to do more research to ensure you truly have a marketable idea.
The second reason is that you don't have a big enough network to find co-founders. This will also be a barrier to launching a startup. For a startup, the network of the founders is essential for both tapping into experience / skills the team does not have as well as for helping develop the market. If this is the case, building your network should come before building your startup.
I hope this gives you some useful things to consider. Let me know if I can be of further help.
I advise Startups and CEOs on their Communication strategy, and part of the strategy involves teams and leadership.
I do understand your challenge, but fear not, there is always a solution!
Try another approach: what is your 'ideal' co-founder?
What do they look like? Picture them, quite literally!
1. Draw up a rough bio for them -
a. experience (in years and type)
b. personality traits (risk taker or risk averse, creative or aggregative...) and
c. what yin-yang relationship you'd like with them.
Remember - your co-founder fills your gaps. If you are the 'idea man', they are the business person, or vice versa.
Once you have a rough idea, try your social networks - LinkedIN has been a good friend to me in this. Invest in their premium account(s) if not already the case, this will show you a lot more than publicly available.
Finally, take a gander on discussion boards in LinkedIN, Quora.com and others that talk about the space your startup belongs in, e.g. Mobile, SaaS, HR Tech, Hardware and so on.
Am more than happy to give you a questionnaire or detailed steps to figure out your best 'match'. Let's talk!
Never waste your time to look around.. Go & get in touch with startup communities like incubators, accelerators, co-working places, collective talks, etc.. Hit ratio would be low but hit effectiveness would be promising..!
You are not trying hard enough. That is why.
1. Have you asked friends and family?
2. Have asked people you work with?
3. Have you attended Tech Meet Ups?
4. Have you attended Hackathons?
Long story short. Try harder!
What do I want from a co-founder?
If your answer is:
Someone to take my idea and turn it into a product, that isn't a cofounder, that is a contractor.
You will be better served learning those skills yourself. If you aren't willing to put the time and effort in to develop your idea, no one else will be either.
