1. The $2,464,628 Portfolio Truth: Settling the 'One-Time Payment vs. Recurring MRR' Debate

For two years, Singapore-based indie hacker Marc Lou (@marclou, 419,622 X followers) was the undisputed king of selling one-time-payment products ($169–$299 boilerplates, courses, and micro-tools). Hundreds of YouTube videos still tell beginners: *'Don't build recurring SaaS! Just launch a one-time boilerplate like ShipFast and make $50K/month!'*

[Verified] Because Marc built TrustMRR and transparently connected the live Stripe API keys for his own five products (ShipFast, CodeFast, DataFast, ZenVoice, and ByeDispute — totaling $2,464,628 in all-time verified revenue as of November 1, 2026), we can inspect the exact daily numbers. And those numbers tell a completely different story today.

2. Why ShipFast Had $0.00 in Sales on 25 of the Last 30 Days ($0.07 Revenue Per Visitor)

Look at the 12-month trajectory across his four one-time-payment products:

ShipFast (shipfa.st, $1,272,892 all-time)
In December 2025, ShipFast still brought in $20,281. By October 2026, monthly revenue had collapsed 91.65% to $1,694. Over the last 30 days, ShipFast collected just $1,395 — recording $0.00 in revenue on 25 out of 30 calendar days (only 5 total sales: two at $249 and three at $299)! Even more revealing, its connected DataFast traffic API shows 19,266 people visited shipfa.st in the last 30 days, yielding a minuscule $0.07 in revenue per visitor (RPV). Why? Because in late 2026, AI coding agents (Cursor, Claude Code, Bolt, Lovable) generate custom Next.js + Stripe + Auth stacks for free in 60 seconds, wiping out the market for $299 static boilerplates.
CodeFast (codefa.st, $835,901 all-time)
His coding course dropped 85.77% from $29,053 in November 2025 to $4,134 in October 2026 ($3,835 30d cash from 6,539 visitors = $0.63 RPV, at a [Self-Reported] 44.0% profit margin).
ZenVoice ($19,688 all-time) & ByeDispute ($9,141 all-time)
Collected just $118 and $202 over the last 30 days. All four one-time products combined generated only $5,550 in the last 30 days!

3. How Recurring SaaS `DataFast` Surged +93.8% to Carry 84.7% of His Entire Income

What saved Marc Lou's monthly cash flow from collapsing by 88%? In July 2024, he pivoted to building a true monthly recurring SaaS: DataFast (datafa.st) — a revenue-first web analytics tool that links website traffic directly to Stripe checkout revenue.

[Verified] While his one-time products fell off a cliff, DataFast's monthly verified cash climbed +93.8% from $16,187 in December 2025 to $31,455 in September 2026 and $31,370 in October 2026 ($30,651 last 30 days; $327,006 all-time). Today, 1,389 active subscribers pay an average of $20.71/month ($28,762 MRR) — meaning DataFast alone generates 84.67% of his $36,201 30-day portfolio cash flow (5.52x all four one-time products combined)!

4. Operator Playbook: Building a Revenue-First Attribution Pipe + Viral RPV Badges

[Estimate / Operator Playbook] Why do 1,389 founders pay $21/mo for DataFast when Google Analytics is free? Because GA4 shows vanity pageviews, whereas DataFast passes a first-party visitor_id into Stripe Checkout metadata and shows one ruthless metric: Revenue Per Visitor ($/visitor) per traffic channel — plus a verified API badge embedded across TrustMRR listings! You can replicate this exact 1KB Cloudflare Worker + Tinybird + Stripe/Shopify webhook architecture in 48 hours.

Three questions to ask about businesses like this

  1. What percentage of your current income resets to $0.00 on the 1st of every month (one-time sales/agency projects) vs. compounding as true recurring MRR?
  2. Do you know your exact Revenue Per Visitor ($/visitor) for each marketing channel
    or are you celebrating vanity traffic that converts at $0.07/visitor?
  3. Can you build a viral verification badge or shareable RPV card into your SaaS so every customer who brags about their metrics on X/LinkedIn advertises your tool for free?

FAQ

Are the revenue numbers for all 5 of Marc Lou's products ($2,464,628 total) verified?

Yes. Every figure comes directly from the read-only Stripe and DataFast API connections on TrustMRR (synced November 1, 2026) for ShipFast ($1,272,892), CodeFast ($835,901), DataFast ($327,006), ZenVoice ($19,688), and ByeDispute ($9,141).

Why did ShipFast drop from $20,281/mo to $1,395/30d while still getting 19,266 visitors?

Two reasons.

(1) AI coding tools (Cursor, Claude, Bolt, v0) commoditized Next.js boilerplate setup, and
(2) one-time-payment products suffer from audience saturation — once your core follower base has bought the lifetime boilerplate, they never pay you again
How does DataFast connect anonymous website visitors to Stripe payments?

A lightweight 1KB script assigns a first-party visitor ID (df_vid), logs the initial referrer and utm_source, and automatically appends client_reference_id=df_vid to Stripe Checkout links. When Stripe fires checkout.session.completed, the webhook joins the settled dollar amount back to the visitor's original traffic source.
