The ThriveCart breaking point
Jacob Pegs was a paying ThriveCart customer until ThriveCart made that impossible to enjoy: prices went up, the platform went down, and support went missing. So he did what a growing number of indie makers do in 2026 — he vibecoded his own checkout. He called it Swipefast.
On October 20, 2026, Pegs posted the first public scoreboard: $6.3k ARR (USD converted), with an ARR chart trending up and to the right. 'For similar reasons when ThriveCart increased prices, downtime and no support, I vibecoded my own solution,' he wrote. 'Now we're rolling.' The post quote-shared an earlier Marc Lou post — 'Their greed is my opportunity' — which has become something of a rallying cry for the build-your-own-SaaS wave.
The timing is worth noting. Checkout infrastructure is famously unsexy and famously sticky — sellers don't switch unless they're angry. ThriveCart gave a meaningful slice of its user base a reason to be angry, and Pegs, who sells to creators for a living, felt it first. Swipefast didn't start as a market analysis. It started as a refund of frustration.
An agentic checkout for creators
Swipefast is an agentic checkout for creators. The pitch is disarmingly simple: tell Claude or ChatGPT what you sell, and the AI drafts your checkout page, order bump and upsell. You approve it, and every sale pays you directly. Plans start at $29/month with a 7-day free trial.
The product sits at the intersection of two trends Pegs has been writing about for months. In his widely-shared 'You + Tools era' essay, he argued that AI's real promise isn't replacing humans but 'taking the weight off' — course watch-time inside his programs is down 33% while AI usage is up 500%, because people want implementation, not information. Swipefast is that thesis as a product: the AI does the checkout-building labor, the creator keeps the judgment and the customer relationship.
It also reflects a shift in who gets to build checkout software. A decade ago, competing with ThriveCart meant a payments team, PCI audits, and years of infrastructure work. Pegs vibecoded the first version himself — the moat isn't the code, it's the distribution and the trust of the creator audience he's spent years building. The AI handles the commodity layer; the founder supplies the reason anyone cares.
The maker behind it
Pegs is not a first-time founder learning in public. By his own accounting, he has generated $1.2M+ as a one-person business, worked with 50+ of the biggest creators online, and built a warm audience of 50,000 LinkedIn followers plus 6,100 email subscribers through his 'Modern Maker' brand. His Substack mixes strategy with unusual candor — one recent post about a 'wild week' of mid-five-figure sales is really about identity: 'They didn't say they hired me for strategy. Or systems. Or even funnels. They said: your vibe.'
That audience is Swipefast's distribution. The testimonials page reads like a group chat of his people: Vincent Claeys did his 'first ever digital sale in 1hr after launching'; brand designer Zubia Hassan switched because it was 'much faster' than ThriveCart for spinning up new checkouts; business consultant Virgil Brewster recorded a 32-second video review — 'one of the best checkouts I've ever seen.' And Pegs himself is the lead case study: over four figures in sales in 11 days, on his own checkout.
This is the part of the story most worth studying. Swipefast's launch didn't need a Product Hunt campaign or paid ads because the founder had spent three years becoming the person his customers trust. When he says 'I built the checkout I wanted,' fifty thousand people believe him — because they've watched him sell with it first.
Early days, public scoreboard
At $6.3k ARR, Swipefast is early — deliberately so. Pegs launched it weeks ago, and the revenue curve in his announcement post is the whole pitch: a solo maker, a real pain, an AI-built product, and customers who were already in his orbit. The next milestone to watch is whether the 'ThriveCart refugees' thesis scales beyond his audience — early replies to his post are already asking whether most Swipefast users are people leaving ThriveCart or new sellers entirely.
Either way, the playbook is now public: find the tool that's mistreating its customers, build the replacement with AI, and sell it to the people already watching you build.
Zoom out and Swipefast looks like a case study in the economics of the vibecoding era. The cost of building a credible ThriveCart competitor collapsed to one motivated founder plus AI tooling — so the binding constraint moved upstream, to trust and distribution. Pegs had both banked before writing a line of checkout code. That's why 'their greed is my opportunity' works as a business strategy now in a way it couldn't five years ago: the aggrieved users are findable, the replacement is buildable in weeks, and the receipts are postable the same day. Swipefast's $6.3k ARR is small in absolute terms. As a proof that the loop works — pain, build, post, revenue — it's one of the cleanest examples of the year.
The playbook
- Build from your own pain — Swipefast exists because ThriveCart — the tool Pegs was paying for — raised prices, suffered downtime, and offered no support. He didn't write a strategy doc; he vibecoded the replacement he wanted to use himself. The best indie products start as the founder's own escape hatch.
- Dogfood publicly — Pegs used Swipefast to sell his own offers first — 'over 4 figures in 11 days since launch' — then published the receipts as testimonials. When the founder is customer #1, every testimonial doubles as a product demo.
- AI drafts, human approves — Swipefast doesn't try to replace the seller's judgment. The AI drafts the checkout, order bump and upsell; the human approves. 'AI taking the weight off' while the creator keeps control — the exact thesis of Pegs' 'You + Tools era' essay.
