Venu is live — here's what I learned validating with 6 real clinics before building

I spent weeks talking to aesthetic clinics in Barcelona before writing a single line of code (well, almost).

Here's what I found:

The real pain:

Every clinic I called manages WhatsApp manually. Between patients. No system. No automation. One owner told me: "sometimes I see the message 3 hours later and the client already went somewhere else."

Estimated cost of not responding in time: €1,200–1,600/month in lost appointments.

What I built:

Venu is a CRM built specifically for aesthetic clinics that automates the WhatsApp layer: identifies whether the person messaging is a returning patient or a new one, responds differently in each case, and books appointments automatically.

No contracts, no complex setup. €149/month flat.

Stack: Next.js + Supabase + GPT-4o + Z-API + Stripe.

What I learned from the process:

1. Pain is confirmed in the first 60 seconds of a call

2. The most common objection: "will the AI understand my clients?" — which led to building the returning vs. new patient detection as a core feature

3. Price isn't the friction — trust is

Where I am now:

MVP in production as of today. Two hot leads. 6 clinics that validated the pain waiting to see the real product.

This week: demos, feedback, first paying customer.

Has anyone gone through a similar B2B outreach process in local niches? What worked for closing the first one?
