A single r/SaaS case study post clocked $1,832 in paid sign‑ups within 48 hours. No ads, no cold email—just a clean Reddit → landing page → Stripe flow. In this guide we'll reverse‑engineer that funnel and show you how to copy it step‑by‑step.

Why Reddit Traffic Converts Like Crazy

• Problem‑aware audience – niche subreddits are basically segmented email lists without the inbox.
• Trust by default – karma acts as social proof; good posts feel like recommendations, not ads.
• Zero‑click research – prospects ask questions right in the thread, giving you live objections to answer.

Funnel Overview (Scroll → Signup → Sale)

1. Hook Post – value‑packed story in r/SaaS (or niche sub).
2. Soft CTA – link in comments to a laser‑focused landing page.
3. Lead Magnet – free tool demo or mini‑PDF in exchange for email.
4. Trial Signup – frictionless form, no credit card required.
5. Upgrade Nudge – in‑app prompt + 3‑email drip, Stripe checkout.

Step 1 – Craft a Post That Doesn't Feel Like Marketing

Redditors flag blatant promos in seconds. Structure your post like a micro‑case study:

• Headline: "We cut payment failures by 27 % with a 3‑line webhook—AMA."
• Body: 150‑word backstory → key metric screenshot → lessons learned.
• Comment CTA: "Happy to share the webhook snippet—grab it here if useful." (link).

Step 2 – Build a 1‑Job Landing Page

Keep the promise tight: deliver exactly what the Reddit comment offered. Layout:

1. Above‑the‑fold headline matching the Reddit hook.
2. Embedded Stripe pricing toggles (monthly / annual).
3. 30‑second Loom demo gif autoplay muted.
4. Email input + "Instant demo access" button.

Step 3 – Collect Emails, Not Just Clicks

We used MailerLite's one‑click OAuth to import Gmail addresses—conversion uptick: +8 %. Immediately redirect to the trial area so momentum isn't lost.

Step 4 – Trial Experience That Sells Itself

• Guided checklist on first login (3 steps max).
• Social proof ribbon: "1,242 founders shipped with us."
• Upgrade button floats bottom‑right on every page.

Step 5 – Stripe Checkout Tweaks

Stripe's default form is great, but tweak metadata for tracking:

• `client_reference_id` → Reddit username (captured at signup).
• `promotion_code` → "RSAAS23" to measure post ROI.
• Enable Link payments for one‑tap mobile conversions.

Results Snapshot (48 Hours)

• 1 Reddit post → 12,644 views
• 623 landing‑page visits (4.9 % CTR from thread)
• 211 email sign‑ups (33.8 %)
• 17 paid upgrades → $1,832 MRR
