Jimmy Cockerton outlines three profitable side hustle models

Jimmy Cockerton argues that building a profitable side hustle doesn’t require a revolutionary idea or startup fame. His own brush with corporate success came in 2021 when he won Microsoft’s Founders Award, an honor given to one employee out of 220,000. As part of the celebration, he participated in a lip sync video with Macklemore, filmed remotely from the rapper’s home in Seattle. Despite 22 hours of preparation and rehearsal, only five seconds of his performance made the final cut.

Three Paths to Profitability

Cockerton says the experience taught him little about building a business. Instead, four personal side hustle attempts shaped his understanding. Two failed outright. Two turned a profit. None resembled a unicorn startup, and that’s precisely the point.

He outlines three models for generating income on the side, each with different requirements and outcomes. The first is the hobby that starts paying. Nearly half of UK adults—46%—already earn money from side gigs like weekend photography, homemade cakes, or handmade candles sold online.

The math, he says, is straightforward. A candle maker’s fixed costs are minimal: Etsy fees and web hosting. Variable costs include wax, wicks, and shipping. Profit begins with the first sale that covers those expenses, and the business can launch within a week.

The second model involves selling expertise. Cockerton’s first two ventures took three years and failed. His third, a consultancy built on existing knowledge, launched in eight months and succeeded. No inventory or apps needed, just invoices and a client base willing to pay for skills already in demand.

But this path has caveats. Payments lag, sometimes by months. One early client took two months to secure, another month to deliver, followed by 30-day payment terms. All the while, costs keep accumulating, in his case, £300 weekly for train fare and dinners during London meetings.

The third model builds a product-based business designed to outlive its founder. Cockerton’s fourth attempt, an impact measurement software tool, launched in two months. He found a market gap by reading a report showing 60% of companies still relied on spreadsheets for tracking social impact. That translated to roughly 8,500 organizations with budgets already allocated for better tools.

He calls it neither brilliant nor disruptive, just informed execution. “That isn’t vision,” he writes. “That’s reading a report properly and then picking up the phone.”

Each model, regardless of scale or ambition, hinges on four core metrics: customer acquisition cost, lifetime value, fixed costs, and break-even volume. These numbers matter more than flashy ideas.

To illustrate, Cockerton invents a fictional service called PawSwap, which connects dog owners with trusted co-caretakers for £9.99 monthly. On paper, it solves a real problem. But churn kills it: users typically resolve their needs in three months, leaving an average revenue per user of just under £30. With £15 spent acquiring each customer and £6 servicing them, only £9 remains to cover £430 in monthly overhead.

That leaves a shortfall requiring nearly 50 new subscribers every month just to stay afloat. “Not vision, not disruption,” Cockerton concludes. “Arithmetic.”

He urges readers to choose a model aligned with their goals, not Silicon Valley fantasies. Extra income? Monetize a hobby quickly. Replace a salary? Leverage professional expertise. Build something enduring? Develop a scalable product and prepare for a long wait.

None demand an MBA or venture capital. Just a customer, a price, and costs manageable on a single hand. His own journey began with a laptop at his kitchen table after long days at work.

Living With Uncertainty

One photographer who received a unit described the daily rhythm of juggling a full-time role alongside a side gig. Twelve-hour stretches became routine, punctuated by moments of doubt and bursts of momentum. The work never paused, even when exhaustion set in.

Counting the Cost

A writer who shaved their head in 2023 reflected on the emotional weight of financial risk. Each failed attempt felt personal, yet lessons accumulated quietly beneath surface setbacks. Progress moved slower than hoped, but consistency eventually paid off.

Choosing the Right Model

Cockerton stresses the importance of aligning a side hustle with personal goals rather than chasing broad definitions of success. Those seeking supplemental income can begin immediately by assigning a price to existing hobbies, even if the offering is imperfect at first. Revenue, he argues, provides faster feedback than prolonged preparation.
