Evergreen Prelaunch Tests: 7 Quick Experiments That Predict Demand (and How to Run Each in Under 72 Hours)

Return to blogEVERGREEN PRELAUNCH TESTS: 7 QUICK EXPERIMENTS THAT PREDICT DEMAND (AND HOW TO RUN EACH IN UNDER 72 HOURS)
If you’re a founder deciding whether to spend months building a product, run a set of high-signal prelaunch tests first. These seven experiments—fake door, concierge, paid-ad smoke test, pricing presale, content CTA, community poll, and onboarding demo—give behavioral evidence (not opinions) about demand. Each test below has a 72-hour run plan, a checklist you can copy, and a simple decision threshold to help you say “build,” “iterate,” or “stop.” AppWispr’s playbook here is practical: no theory, just repeatable steps and templates you can reuse in your next weekend of validation.
Section 1
1) Fake Door (Painted Door) — Fastest behavioral signal
What it is: put a realistic entry point (button, menu item, feature link, or landing page CTA) in front of your users that pretends the product or feature exists. Track clicks and sign-ups as behavioral interest signals rather than survey responses.
72-hour plan: create a one‑page landing or in‑app CTA, wire the CTA to a short sign-up or ‘notify me’ flow, run it for 48–72 hours on targeted channels, and measure conversion and email quality (work vs. personal emails).
- Checklist: headline + single outcome, 1 CTA, short signup form (email + 1 qualifying Q), analytics (GA/Amplitude), copy for the post-CTA 'not yet available' page asking for reason and willingness to pay.
- Decision threshold (example): >2% CTR from product users or >10% landing-page sign-up from targeted ad traffic = proceed to concierge or presale; <1% = rethink the value prop.

2) Concierge MVP — Manually deliver value to test monetization
What it is: do the product work by hand for a few customers to test if they’ll actually use and pay for the outcome. The goal is to validate the core job-to-be-done and early willingness to exchange money or attention.
72-hour plan: recruit 3–10 target users (via your network, communities, or fake-door signups), agree on a simple deliverable and price, deliver the service manually using spreadsheets, email, and calls, then measure repeat interest and time-to-value.
- Checklist: 3–10 initial users, standard intake form, one-person operations playbook (steps, deliverables, turnaround time), invoice or payment link, feedback script.
- Decision threshold (example): if ≥40% of first customers pay and at least 50% request a second delivery or extension, the problem is validated; if customers pay but churn immediately, fix retention problems before building.

3) Paid-Ad Smoke Test — Control traffic, measure conversion cost
What it is: send targeted paid traffic (search, social, or niche Network) to a landing page describing the promised outcome and track sign-ups or purchases. This tests both demand volume and customer acquisition economics.
72-hour plan: build a single-focus landing page, set up a small targeted campaign ($50–$300 total), measure CTR, landing page conversion rate, and cost-per-acquisition (CPA) for meaningful leads.
- Checklist: single promise headline, hero benefit, 1 CTA, analytics (UTM, GA), ad creative variants (2–3), daily budget caps, and clear measurement of CPA and lead quality.
- Decision threshold (example): if CPA for a qualified lead is less than 25–30% of your projected LTV (or a realistic first-sale price), pursue build; if CPA is much higher, reconsider channels or product-market fit.

4) Pricing Presale (High‑Bar Smoke Test) — Test willingness to pay
What it is: present real pricing and ask for a commitment (preorder, refundable deposit, or paid pilot) to validate price elasticity and early revenue potential. Unlike free sign-ups, money separates talk from intent.
72-hour plan: add a checkout or ‘reserve’ button to your landing page, offer a clear refund/fulfillment policy, run targeted traffic or invite fake-door signups to the page, and measure conversion and average order value.
- Checklist: tested pricing tiers, one-line guarantee (refund or first access), payment processor or Stripe Checkout, basic order confirmation flow, tracking for conversion rate and chargebacks.
- Decision threshold (example): 5–10% conversion on warm, qualified traffic into paid reservations is strong signal to build; <1% suggests price or value mismatch.

5) Content CTA (Value-First List-Build) — Organic demand + qualification
What it is: publish a short, tightly-targeted piece of content (guide, case study, or micro-video) that solves a small part of your target user's problem and embeds a single CTA offering a deeper product benefit or early access.
72-hour plan: write one high-signal piece, promote it in 1–2 relevant communities and via a small paid boost, measure content engagement to CTA conversion and the quality of the leads you capture.
- Checklist: 800–1,200 word mini-guide or 3–5 minute video, one CTA leading to a waitlist or demo booking, UTM-tracked links, and a follow-up email sequence to qualify intent.
- Decision threshold (example): if 15–25% of engaged readers click CTA and at least 30% of those are qualified leads (work emails, correct role), you have organic signal worth amplifying.

FAQ
Common follow-up questions
How long should I run each test?
Aim for 48–72 hours to get an initial signal and iterate quickly. Short tests let you test multiple ideas in a week—longer runs are only necessary if traffic is low or you need seasonal validation.
What counts as a qualified lead?
A qualified lead depends on your product but commonly includes a work email (not generic), correct role or company size, and a clear expression of intent (booking a demo, paying a deposit, or requesting a pilot). Use at least two criteria before counting someone as qualified.
Aren’t fake doors unethical?
Fake-door tests can feel deceptive if handled poorly. Be transparent on the post-click flow (e.g., ‘We’re launching soon—join the waitlist’) and avoid collecting payment for products you can’t reasonably deliver. If you collect money, fulfill it via concierge or refunds.
Which test should I run first?
Start with a fake door or content CTA for earliest behavioral signal; if that shows intent, run a concierge MVP or pricing presale to validate monetization. Paid-ad smoke tests are best when you need to estimate acquisition costs.
