growth at $1M+ GMV — run by a team of one

  • Customer: CarsnCards
  • Speaker: Donny Araujo, Founder

The challenge: enterprise ambitions, solo bandwidth

Carsncards.com is a fast-growing diecast and trading card retailer with an Ottawa brick-and-mortar storefront and a thriving online business. Hot Wheels, Formula 1 collectibles, and high-end racing diecast move through the site at a clip that has pushed annual GMV past $1M and growth past 300% year over year.

All of it runs through one person: Donny Araujo.

Between fulfilling orders, answering customer emails, managing the physical store, and running paid ads, Donny had ambitions to make his site faster, optimize his product pages, and tighten his ad spend. He bought into the standard playbook — layer in session replay, plug in Shopify analytics, try out a free behavioural analytics tool, look into customer journey software. The tooling was there. The bandwidth wasn’t.

“I’d spend hours fumbling around inside these tools trying to figure out what to actually do. Between writing emails, processing orders, and answering customers, the time just wasn’t there to extract any real value from them.”
— Donny Araujo, Founder, carsncards.com

Each tool surfaced fragments. None of them connected to ad spend. None of them told him what to do next. And none of them were built for someone whose full-time job is everything else.

The shift: one connected platform, five autonomous workflows

When Donny adopted Noibu, the immediate unlock wasn’t a new dashboard — it was consolidation. Heatmaps, session replay, performance data, errors, accessibility, and marketing attribution all flowed into a single ecommerce-native data layer. From there, the Noibu connector exposed that data to LLM platforms like Claude, where pre-built skills could turn raw signal into actual work.

That changed the question. It was no longer “which tool do I open today?” It was “which workflow should run this week?” Donny now operates five workflows on a continuous weekly cadence, each one ending in a human approval gate before anything ships:

Page speed optimization

The agent pulls the theme from GitHub, finds slow high-traffic URLs, runs Core Web Vitals checks, and writes fixes directly into a PR for review.

🛒

PDP conversion mapping

Weekly, the agent benchmarks the five lowest-converting PDPs against the five best — surfacing layout, copy, and merchandising fixes as PRs.

🐛

Error monitoring

Front-end errors are triaged automatically, prioritized by occurrence and revenue impact, and routed into fix-ready PRs.

ADA compliance

Accessibility issues are scanned continuously and surfaced with proposed remediations, keeping the site compliant without dedicated audits.

💰

ROAS rebalancing

The agent watches ad performance against real demand signals and recommends weekly budget shifts — like rebalancing F1 spend on non-race weeks.

Each workflow runs the way a specialist hire would: continuously, with judgment, and with the work staged for sign-off rather than dropped on his plate as another to-do.

The proof: 25% faster, conversion up from 0.8% to 1.1%

Across a 30-day window, the combined output of these workflows produced measurable movement on the metrics that matter most:

  • Homepage load speed improved by 25%, driven by the page speed agent’s weekly PRs.
  • Site-wide conversion rate climbed from 0.8% to 1.1% — a direct downstream effect of faster pages, sharper PDPs, fewer errors, and better-targeted ad spend.

For a business growing at 300% year over year, a 37.5% lift in conversion compounds quickly. And it happened without Donny adding a single hire.

“This has been an absolute game changer. Noibu’s data paired with best-of-breed AI has basically unlocked what it would feel like to hire a team of ten people.”
— Donny Araujo, Founder, carsncards.com

Why it works: enterprise workflows, no enterprise overhead or cost

The model that Donny is running used to be reserved for ecommerce teams with the headcount and budget to staff a performance engineer, a CRO specialist, a QA lead, an accessibility consultant, and a paid media analyst. Most resource-constrained operators — the founder who is also the merchandiser, who is also the customer service desk, who is also the marketer — have to pick one or two of those disciplines and let the rest slip.

Noibu collapses that trade-off. The data layer is unified. The agents do the analysis. The pull requests stage the work. Donny stays in the driver’s seat with the approval gate, but the time cost of running enterprise-grade ops drops to near zero. Donny notes how simple the set up was, “took me a few hours one afternoon” and additionally mentioned a palatable cost.

That’s the shift. Not a faster dashboard. Not a smarter alert. A different operating model — one where a solo operator can run the same playbook as a ten-person ecommerce team, and put the saved hours back into the parts of the business that actually need a human.

The results: Enterprise-grade ops, zero added headcount

By consolidating performance, behavior, error, accessibility, and ad-spend data into Noibu — and running continuous agent workflows on top — Donny turned a one-person operation into a ten-person team:

25% faster homepage load time — driven by weekly agent-generated PRs to the theme

📈

Site-wide conversion lifted from 0.8% to 1.1% — a 37.5% increase in 30 days

🤖

5 autonomous workflows running weekly — page speed, PDP CRO, errors, ADA, and ROAS

$1M+ GMV at 300% YoY growth — run entirely by a solo operator


Frequently asked questions

What challenges did Carsncards.com face before Noibu?
Donny Araujo runs Carsncards.com almost entirely on his own — fulfilling orders, answering customer emails, managing a physical storefront, and running paid ads. He had ambitions to make the site faster, optimize product pages, and tighten ad spend, and had layered in session replay, Shopify analytics, a free behavioural analytics tool, and customer journey software to try to get there. The tooling was in place, but the bandwidth wasn't. Each tool surfaced fragments, none connected to ad spend, and none told him what to actually do next.
How did Noibu change the way Carsncards.com operates?
Noibu consolidated heatmaps, session replay, performance data, errors, accessibility, and marketing attribution into a single ecommerce-native data layer.

The question shifted from "which tool do I open today?" to "which workflow should run this week?"
What workflows does Carsncards.com run on Noibu?
Five autonomous workflows run on a continuous weekly cadence, each ending in a human approval gate: page speed optimization (PRs generated against the live theme), PDP conversion mapping (benchmarking lowest-converting pages against best performers), error monitoring (front-end errors triaged and routed into fix-ready PRs), ADA compliance (continuous accessibility scans with proposed remediations), and ROAS rebalancing (weekly ad budget shifts based on real demand signals).
What results has Carsncards.com seen with Noibu?
Across a 30-day window, homepage load speed improved by 25%, and site-wide conversion rate climbed from 0.8% to 1.1% — a 37.5% lift. For a business already growing 300% year over year at $1M+ GMV, that compounds quickly. And it happened without Donny adding a single hire.
How is a solo operator running enterprise-grade ecommerce ops?
The operating model Donny runs used to require a performance engineer, a CRO specialist, a QA lead, an accessibility consultant, and a paid media analyst. Noibu collapses that trade-off: the data layer is unified, the agents do the analysis, and the pull requests stage the work. Donny stays in the driver's seat at the approval gate, but the time cost of running the playbook drops to near zero — putting saved hours back into the parts of the business that actually need a human.
