Let's just agree that every case is different. There's no ONE right answer here.
Was it you alone, too, in your previous startups? All of them? Any of them?
Do you believe being alone is one major reason why it's growing faster than ever? The main reason? Why or why not?
Sorry for the interrogation and TIA!
Just make sure you pick the partner carefully. I think we've all had partners that were worse than nothing.
From the title, one would expect you had some experience to share.
When it comes down to it, we don't do well alone.
If you want to have word play and add additions like.. I'm alone and a startup, but I have a fantastic group of individuals I surround myself with...or I have a family that really cares. That's not really alone is it?
I don't see many isolated entrepreneurs that stay alone and never give up the control--and grow. How would you hire and instill passion? How would you not have a motley crew of cog creators?
Having a partner, or general support, is the groundwork for a network. A network is what allows us all to play, create, and grow.
