⭐ My free LLC deadline checker is live on Product Hunt today β€” would love your feedback

Quick update β€” DeadlineSentry is live on Product Hunt today! πŸ›‘οΈ

Since I last posted here it's grown a lot β€” the free checker now covers 24 states plus federal Form 5472, showing your LLC's exact annual report deadline, filing fee, and late penalty in about 10 seconds.

If you've got a minute, I'd genuinely love your honest feedback: is your state covered? Anything wrong or missing? And which state should I add next β€” I'll build it.

And thanks to everyone here who gave feedback early on β€” it shaped a lot of where this went.

    The interesting part is that you're validating before building, but there are several different assumptions bundled into the managed-backend idea.

    Of the conversations you've had with AI builders so far, what have you heard that has made you most uncertain about whether this should become an MVP at all?

      Thanks for reading! Quick clarification though β€” DeadlineSentry's already built and live: a free checker covering 24 states plus Form 5472. So I'm past the "should this be an MVP" stage and into growing it. Always happy to hear from anyone who's actually used it β€” did you get a chance to try the checker?

        Thanks for the clarification β€” I missed that you were already past the MVP stage.

        I was more interested in the validation of the underlying demand, but it makes sense that the question now shifts toward usage and growth rather than whether to build it.

          Appreciate it! The demand validation came the hard way β€” I kept getting blindsided by these deadlines myself, then realized how many people are searching for exactly this info every month (turns out, a lot). If you ever spin up an LLC, give the checker a run and tell me what you think. Thanks for the thoughtful questions πŸ‘

            You’ve clearly got an interesting signal here. I’d like to continue the conversation outside the thread if you’re open to it. What’s the best email to reach you on?
