I have built a landing page for my SaaS. Should I launch it at this stage?

Hello my dear indie hackers.

Recently I have been working on a trimmed down version of a saas product of which I launched a sign up landing page last year and I got positive responses.

My dilemma now is as follows.

I have build a much better landing page which describes and illustrates a subset of the features of the saas I showed last year.

My plan is to get it live this week and have a sign up form asking for only the user's email address and then contact them for feedback. Just like I did before.

I have mixed feelings about this as it looks like repeating the same steps, on the other hand this saas is more focused on the solution with more details.

For the next step I am thinking of building it by first implementing the bare minimum of the features, make it available with a free subscription but limited in terms of volume. And gradually build the rest of the premium tiers while gaining free user's(early adopters).

Just to make it clear it is not a ground breaking solution, there are some big companies out there making millions out of their solutions. I'm just trying to bring another option to the table with little differences initially, hoping to get a piece of the pie, as I believe there is gap in the market. At least in the UK where I am based. (Most competitors are us based for all it matters)

What are your opinions about my thoughts guys?

I apologize for the long post.

Thanks
