Tailor
Joe D'elia, a 25-year-old developer from London, was following the "12 startups in 12 months" philosophy popularized by Pieter Levels. While working on A/B testing for his other projects, he noticed existing tools were overly complex and statistics-focused. He wanted something simpler: the ability to test a variant on 10% of traffic and automatically show the winner to the remaining 90%, skipping the evaluation process entirely.
Joe built Tailor in PHP using Laravel over approximately 2 months of nearly full-time work. The initial product "looked like crap" and had major issues—most critically, his math was completely broken and the system essentially chose random options instead of the best-performing variants. He also struggled with building a visual editor, which consumed significant time but ultimately didn't work. Despite these technical problems, he kept refining the design and landing page.
When launching, Joe leveraged connections from his previous product Anymail Finder. A contact who had helped promote Anymail Finder on Product Hunt agreed to post Tailor there, which drove significant traffic. He also placed an ad on Anymail Finder itself. These efforts resulted in around 800 signups, but Joe failed to properly onboard or convert these users into paying customers.
The Product Hunt launch was the only marketing success—it generated substantial traffic and awareness. However, everything else failed. Joe spent 90% of his time building and only 10% on marketing. The product itself didn't work reliably, and he was targeting the wrong audience (small websites that would never see statistical significance). More fundamentally, he didn't validate the idea before investing 2 months, and he lacked any marketing or sales expertise. He later realized that even if he'd partnered with a marketing person, the flawed product would have meant wasted time and money.
Joe shut down Tailor and refocused on Anymail Finder, which was already generating around $2,000/month and had product-market fit. He learned valuable lessons about validation, marketing, and the dangers of the "launch many products quickly" approach. He is now co-founder of Upscope, a screen sharing software, and advocates for building one product deeply rather than many products shallowly.
- •Product-first thinking without product-market validation is fatal: Joe built for 2 months without validating whether customers actually wanted a simpler A/B testing tool, leading to a broken product that solved the wrong problem.
- •Confusing virality with traction: A Product Hunt launch brought 800 signups but Joe had no system to convert them; he relied on passive discovery rather than active marketing and sales.
- •Following trends (12-in-12 challenge) without realistic constraints: The framework forced Joe to launch quickly rather than grow deeply, preventing him from focusing on the one product (Anymail Finder) that was actually working.
- •Technical founders must pair building with marketing expertise: Joe spent 90% of time coding and 10% marketing, creating a skilled-imbalance that ensured failure even if the product had worked.
- 1.Validate before building: Spend weeks interviewing potential customers and pre-selling your concept before writing code; Joe could have discovered the market didn't need this in days.
- 2.Build partnerships with proven launch channels: Identify influencers or connectors in your space who can amplify your launch (Joe's success with Product Hunt came from a personal connection, not cold outreach).
- 3.Commit to one product and one growth channel: Instead of the 12-in-12 challenge, pick your best idea and focus 80% of energy on one metric (activation, retention, or revenue) for 3-6 months.
- 4.Hire or co-found with a marketing/sales person early: Don't assume a good product sells itself; Joe acknowledged his Anymail Finder succeeded partly because it had obvious appeal, but Tailor required sales effort he never invested.
