Hi IH — quick update. The MVP is live.

Back in March I said MVP in 60 days. It took closer to 95. Here's what actually shipped and what I learned.

What I built:

Nudge ( staging.usenudge.io ) watches your customer list, spots who hasn't been back in a while, and sends them a personalised re-engagement email automatically.

The AI knows their actual visit history, what services they got, your brand voice, and your pricing (if you opt in). It doesn't invent facts. If it can't ground a claim in your real data, it throws it out and retries.

No templates. No "Hi [Name], we miss you."

What's different from my March plan:

I underestimated the prompt engineering side. Getting the AI to write emails that sound like you - not like a chatbot - took real work. I ended up building a fact-grounding validator that rejects any generated email containing a price, service name, or staff member that doesn't match your actual data. That alone took 2 extra weeks.

Worth it.

Where things stand:

What I need:

The first 10 service businesses to actually use it. Salons, barbershops, yoga studios, gyms — anyone with repeat customers they're not following up with. Free access, I just want real feedback.

If that's you, or you know someone -> drop a comment or reply here.

Still posting real numbers and honest mistakes as I go.

    Diniranga, I think the bigger risk now is not the emails.

    It's getting feedback from the wrong businesses.

    A salon owner who logs in once and says "looks good" is very different from a salon owner who actually has dormant customers worth winning back.

    For the first 10 users, I'd be less focused on service businesses broadly and more focused on businesses that already know repeat visits drive revenue but are not consistently following up.

    The reason is that you'll learn much faster whether Nudge is solving a retention problem or just generating interesting emails.

    The first-10-user acquisition path feels more important than the next product feature right now. Happy to put the tighter version in writing if useful.
