In a word, no.
It's not the idea -
They will all remain constant as you jump from idea to idea.
Pick one product and put 10x the effort into that!
The traditional startup approach resembles throwing software against a market and see what sticks. Throwing 10 apps (assuming you can somehow execute) might win the lottery.
However, there's a better approach: Lean Startup. Instead of building and see who buys, do your learning up front, find the right product/market fit for you and your prospective customerbase and take guessing out of the startup equation.
I'd suggest you actually would have either a 90% chance or a 1% chance of succeeding.
Either you'd learn so much from each startup that you'd eventually know how to turn one into a success;
You'd spread yourself so thin and wear yourself out so much that you'd give up or just outright fail.
Yes, you can. You need to win only once although there are some problems :
Finally there is big mental problem about knowing that you can try again and again and again, you might not give you best shot and declare failure prematurely.
If you try sequentially Maybe Yes But if you try all at once No "The wider you spread it, the thinner it gets"
from "The Secrets of Consulting” by Gerald M. Weinberg
What is the definition of failed? I knew of one millionaire (due to personal patent defenses) who has run a company over 25 years and has yet to make a profit. His employees and customers see it as a success, but for the rest of us, no profit = failure.
The question is, what are the odds a "founder" will fail and what is the impact of multiple attempts on his/her success rate? Can't recall the source, but seems like those that fail are more likely to fail again.
Just think about it. You're not able to identify what's important and how to execute it on a daily basis with startup 'A', but all the sudden, you've learned your lesson. Closed the door on A and applied all this knowledge to B.
Many successful companies started in one product line/industry, made a change and became very successful. Should that transition be considered a new startup? Maybe the odds would improve on the percent of successes if it were.
It might because you'd identify certain points that reiterate across your first three startups, and then you'll be able to apply them to future ones. The problem here is that you'd enter into two situations.
So just pick the best out of your ideas: this is the one that is both currently doable and the most brilliant. A premium blend of the two will increase your chances of succeeding.
I will say that 10 mean players do not make 1 chess master. Trying to execute 10 start-up ideas do not raise the chance of success. It is idea+execution that matter, but also location and chance.
If I had 10 ideas that I thought were viable, I would create 10 pre-launch landing pages and start gathering customer data/feedback. Use AdWords (very low budget) to generate the traffic. Have a lead capture process and see what type of conversion rates you get.
Maybe 9 out of 10 fail on this first step and help you get focused.
