Pivoting our SaaS: Stick with Business Owners or chase Marketing Agencies?

My two co-founders and I have been building WebGremlin, our first SaaS, for 1-2 months now. It’s a website analysis tool. After we did the customer dev, we targeted three groups: business owners, marketers, and marketing agencies. We validated business owners with an MVP and made a few sales, so we started working on version 1.

We are having a soft launch now and it showed lower than expected conversion from business owners. However a few marketing agencies reached out, asking for an agency plan and are ready to pay, even without the features they want, basically saying "shut up and take my money".

Now we’re stuck. Agencies seem like the hotter market, but pivoting means redoing our homepage, marketing, and adding features, more dev work when I’d rather focus on marketing. Also we haven't done our official launch so it's still early to say if we should pivot or not.

Do we stick with business owners or pivot to agencies?
What’s the smart move here?
