Fly Labs Method
Is the pain real, is there a gap, is it the right time, can one person build it.
The problem is real and severe, but the market is dominated by well-funded players. While there are clear frustrations with existing tools, creating a truly differentiated and simple solution for SMBs while competing against giants is a monumental task for a solo builder. Buildability is also a significant hurdle.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
Potentially profitable due to high market pain, but the crowded competitive landscape and build complexity for a solo founder present significant challenges for differentiation and execution.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
Clear problem, but high technical complexity and difficult differentiation in a crowded market make it challenging for a solo builder.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
Strong value proposition and business model, but high assumption risk regarding market entry against incumbents and a lack of direct validation.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
Strong demand and future potential, but a lack of specific, desperate users and a very narrow, observable wedge makes it hard to start small and gain traction.

This one is almost too effective to share. Every SaaS has unhappy customers. Those customers go to Reddit and vent publicly. And those complaints are your best sales opportunities. **Here's why this is so powerful:** these people already understand the problem space (no education needed), already have budget allocated (they're paying a competitor), are actively unhappy (ready to switch), and are publicly asking for alternatives. That's the highest-intent prospect you'll ever find. Higher than any ad click. Higher than any cold email response. **The method:** **Step 1:** List your top 5 competitors. **Step 2:** Search Reddit for "\[competitor name\]" alternative OR "\[competitor name\]" issue OR "\[competitor name\]" pricing **Step 3:** You'll find dozens of frustrated users describing exactly what they wish was different. **Step 4:** Write a genuinely helpful comment. Don't trash the competitor that looks petty. Instead, acknowledge their frustration and offer objective alternatives: "I've used \[competitor\] too and had similar issues with X. Depending on what matters most to you, here are 3 alternatives I've tested: \[tool A\] for Y, \[tool B\] for Z, and \[your tool\] if you specifically need W." **The key:** be honest and balanced. Recommend competitors when they're genuinely better for that use case. People trust someone who gives objective advice over someone who only pushes their own product. **My results from last month:** 3 customers in one month (high ticket niche), started this strategy since Jan. 2026 + this will compound over time the more I find posts to comment. The hardest part is finding these conversations across 50+ subreddits consistently. I use AI Reddit tools like Reppit AI to monitor competitor mentions in real-time, which surfaces opportunities I'd never find manually. Try it this week: search your #1 competitor's name + "alternative" on Reddit. I guarantee you'll find warm prospects over time, as these posts already rank on goog
