Solo or a team of founders?

I will be the first. I had several different startups, sometimes, I was solo, and sometimes, we had a founding team. Now, I am a solo founder who considers it necessary to give stock options to the teammates so that, over time, they become full-fledged partners. In my opinion, the main goal of working with partners when starting a team is the professional experience of the founders in different areas. For example, you are an excellent technical specialist, and your partner is an excellent marketer. If you and your partners are both excellent, for example, marketers, then such a partnership is more likely to be competition within the team. Therefore, if you are sure that your sales, marketing, and development skills are good enough, then you can be a solo founder.
