Should I pivot or am I being impulsive?

I would talk to the 70 beta users and measure for any sign of product market fit. Measure actual usage and what value they are getting from your tool. Why did you build this tool in the first place? Often times you'll have the ideal target audience starring at you, you just have to spend a few minutes thinking and look.

1. I think you are jumping the gun on investors. If you go tell investors that I have this cool tool they will give you the answer you just got.
2. The fact that you don't even know how to monetize your platform shows that you are more of an engineer and less of a business person. I would suggest watch some youtube videos on monetization/pricing.
3. Once you have decided how to monetize then test it with your users. Existing and new.
4. Investors would like to see your target market (that can be content marketers ), usage and revenue.
5. To narrow down the focus you should do two things a) look what profile a majority of your users have e.g. content marketers, sales etc. b) ping content marketers you know and ask them to try the product for free for 14 days. On 14th day put a link to a Paypal payments page and ask them to pay.
6. Just remember a product for everyone is a product for no one. And a product that cannot be monetized is for everyone but you.

Good Luck!

considering pivoting to focus on content marketers...
but I'll need to add some more features.

Looks like a great tool as-is but fair point on the money.

I’d put up a sub-page on your site listing those features and float that around the content marketing circles. Maybe even try pre-orders, do you think that’ll work? Or what if you asked your existing 70 users to pay a one-time fee for this new product and see how many convert? Just a thought.

How long usage data do you have on them?
Is the way to get the users reusable or 1off?

How many of them wrote at least 3 or even 10 things over multiple days?...
Like are they coming back after that first attempt?

What knowledge can you get on the current most active users? Can you interview them and learn something?

How long did it take you to get to 70 users? How did you get them? My initial reaction is that you’re being impulsive. Asking how you’ll make money could either be a good question or a completely awful one, especially for an early stage startup. WhatsApp sold for $22b and had $10m in revenue.
