I will not promote. Should i focus on building MVP for b2b or start trying to get b2c customers?

I am currently building a notes workspace app which i believe will be more suitable for teams to use. It focuses more on a scattering of documents problem which natively occurs more in team based situations, rather than individual situations. The problem is, trying to code out a full b2b version requires much more time to make the collaboration features, and honestly at this point i dont even know if my MVP/product is good. Which is why im thinking of targetting b2c first which is what most notes apps do. H
