Validation sprint · for pre-launch founders & SMBs

Validate your demand. In 90 days.

You get a branded web page with a privacy-clean waitlist and double opt-in on your own domain. Fully set up, we run it for 90 days. Fixed price, no subscription. In the end you don't just hold a list of interested customers, you hold solid proof that your product is wanted.

What every confirmed signup looks like. The proof that makes your launch and marketing emails legally safe.

The fear of building the wrong thing

Building on an idea for months when no one knows whether anyone even wants it, and getting it legally watertight on top of that, feels like risk.

Months built on a hunch

You pour time and money into an idea without enough evidence that anyone even wants it.

A list that's worthless in court

Without clean double opt-in your waitlist is legally exposed, at worst a cease-and-desist instead of an opportunity.

Time lost in technical weeds

Domain setup, sending, deliverability... instead of talking to customers you sink weeks into plumbing you'll never touch again.

It looks like a DIY hack

"Is a bare form legit enough to put my name next to it?" Probably not, and your first prospects can feel it too.

Interested customers you're allowed to email on launch day

That's the real value, not just email addresses but confirmed consent. Every signup carries email, timestamp, IP and a confirmation token; that's exactly why the list holds up legally and is worth €399.

Your own waitlist web page
Designed in your look, on your own domain, with a double-opt-in form. Not a builder template you wire up yourself.
Your own EU database
A dedicated project, hosted in the EU. No shared tables, the GDPR cleanliness is the product.
One launch email
At go-live an email in your look goes out to the confirmed list. The moment double opt-in pays off.
Insights from day 1, the result on day 90
You watch signups come in live from day one. On day 90 you get the full export with the consent record, plus the solid read on your demand.

How the sprint runs

1

Briefing & design

You bring the idea, audience and your logos and colors. We create the page.

2

Live on your domain

The waitlist goes live on your own www domain. Cleanly designed, consistent with your brand.

3

You distribute the link

Reach is your job. We supply the stage, you bring the visitors.

4

The waitlist collects

Every signup is confirmed by email instantly, even in a spike.

5

Launch email

A launch email in your look to all confirmed contacts, sent by us.

6

Day 90: an answer in hand

A proofed list plus a readout. Then you decide what's next.

Why done-for-you beats DIY

A bare form is available on other platforms. The honest comparison:

Built yourself

~€60 in tools

  • Plus your hours for domain setup, double opt-in, GDPR, consistency and much more
  • Plus the legal risk if the proof is missing
  • A legally exposed list, no readout
  • Cheaper on paper BUT you pay with time and risk

Waitlist Sprint

€399 one-time

  • Fully designed, on your domain, live in days
  • GDPR-clean from the ground up: double opt-in, EU hosting, DPA, deletion
  • A solid consent record per signup
  • Insights from day 1, a solid result on day 90. A decision, not a maze of complications

Day 90 is a fork, not a hard stop

You hold a result and decide what's next. The results are yours.

"I got my answer"

Clean close

A proofed list plus a how-to. Page offline, data deleted (Art. 17). Included.

"I'll run it myself"

Run it yourself

We set up your own sending account, verify your domain and hand everything over cleanly. Ready to start.

"Do it for me"

We take over

The list stays live, we keep sending your campaigns and handle deliverability.

"It works and I want more"

Now scale for real

Validated demand becomes an MVP or a finished website. From discovery to product.

Working together means "we keep operating it" and never "we keep your data." The way back to doing it yourself always stays open, guaranteed.

One price. Fixed. One-time.
