“I started looking on forums and I noticed there were a lot of other IT admins that had the exact same problem.”
Look for Pain Points in Forums Before Building Anything
Thomas didn't start with a clever idea — he started with a real complaint he personally experienced at work, then cross-referenced it against forum conversations to confirm he wasn't alone. This community-based validation gave him confidence that a market existed before he wrote a single line of code. The pattern: live inside the problem, then find others who share it.
“when you first come up with a product or business idea it's almost 100% guaranteed that somebody else has come up with that idea before... you need to evaluate the competition and see if there's any kind of space for you to squeeze in”
Validate Ideas by Finding Existing Competition and Beating It
The presence of competitors is not a red flag but a confirmation of demand. Ure's validation lens focuses on two angles: can you build a better product, or can you outmarket them? This reframes ideation from novelty-seeking to competitive gap analysis.
“don't go into business being like 'I'm going to buy Facebook ads and sell it to some stranger in Arkansas'... it's got to be someone you know”
Validate Your Idea by Selling to Your Personal Network First
Before spending a dollar on ads, Ian sold his first three contracts at a steep discount purely to friends and connections. He used those relationships as a live test of market demand, reasoning that if someone who trusts you won't pay for it, a stranger never will. This 'sell to people you know first' filter is a low-cost way to validate product-market fit before scaling acquisition.
“there was a lot of anxiety when I tapped out my network I was like what if this is just a business where people I call and they like me or they know me will buy it and then it stops”
When Referrals From Strangers Start Arriving, Your Business Is Real
After signing his first customers through personal relationships, Ian hit a defining moment of doubt: was this a real business or just goodwill from friends? The anxiety resolved only when referrals started coming in from strangers. This transition — from network sales to word-of-mouth from people you've never met — is the real validation signal founders should watch for.
“I predicted that if I had just built my SAS business on the back of my personal brand and me telling my own fans to buy it it wouldn't survive in the wild when I say wild I mean in the market and among the competition of other SAS companies that would build similar products as mine.”
Test Your Product in the Wild Before Betting on Brand Loyalty
Sebastian had nearly 1 million YouTube subscribers he could have pushed the product to, but deliberately chose not to. He reasoned that audience-driven sales wouldn't reveal whether the product was truly competitive against real alternatives. He wanted proof that strangers would pay for it without any personal endorsement.
“I think it taught me a valuable lesson about test first and then build don't build then test you can waste years building a startup or a game and then it ends up being worth nothing but if you build it and it somewhat works to begin with you know you have something”
Test the Concept First Before Building the Full Product
Cole spent three years and $300,000 building an ambitious game that failed. After watching his brother Ian build a viral hit over a single college winter break, Cole called his programmer and said 'let's make a game in 2 weeks.' That constraint crystallized a core principle he now lives by: validate before investing deeply.
“as I started using Chat GPT I realized that there were some things missing there was some features that I wish were there you know at the beginning you couldn't search your chats you couldn't put things into folders all these little quality of life things started piling up i knew that I could make something better”
Scratch Your Own Itch to Find a Product Idea Worth Building
Dustin had no formal developer background and no budget to hire. Rather than running surveys or market research, he simply used the dominant product in his target market daily until frustrations became obvious. Those accumulated frustrations became his feature list for Magi.
“I would go in that server and I would join a discord voice chat and I would share my screen not talking nothing just me using my tool and I was seeing Sam what are you using at Sam what is this and I would respond to him being 'Oh it's a tool I built.'”
Lurk in Discord Voice Chats and Let Curiosity Pull Customers to You
Sam avoided Discord's strict no-self-promo rules entirely by entering voice channels silently and demonstrating value through action rather than pitching. The curiosity hook did all the selling. Within a week the server owner made a promotional YouTube video about the tool unprompted, without Sam asking or paying.
“I have one rule that is really crucial for me is to never build something that doesn't already exist and isn't already successful or at least getting some traction so this way I reduce my chance of failure and I increase my chances of success”
Never Build Something That Doesn't Already Exist and Work
Samuel frames his entire strategy around eliminating the idea-risk that kills most indie projects. Rather than validating a hypothesis, he only enters markets where someone else has already done that work. This one rule is the foundation all three of his $35K/month businesses were built on.
“I analyze how they are getting their customers so I use href to check their traffic sources so are they getting customers only from ads or are they also ranking on SEO if they are growing with both ads and SEO that's a very good sign because it shows a strong demand and it's usually easier to replicate their success”
Find a Proven App Then Check Its Traffic Source Before Cloning
Samuel describes his exact validation checklist beyond just checking MRR screenshots. He digs into traffic sources using Ahrefs to understand whether demand is sustainable and replicable. An app growing on both paid and organic signals is easier to clone because the paid channel can be turned on immediately.
“a friend told me about how he was struggling to stay on task and motivated. So that sparked an idea.”
Validate Your App Idea by Listening to Real Friends' Pain Points
Evan didn't do formal market research. After two apps that went nowhere, the idea for Locked came directly from a friend describing a real problem he was having. Building around that specific pain — rather than a market gap — gave the product an authentic foundation from day one.
“I got the first sales minutes after my first Reddit post i've never seen anything like that before and that was a clear sign that my idea was validated”
Use Immediate Sales as the Only Validation Signal That Matters
Dennis posted screenshots of his app on Reddit and got blocked almost immediately, but not before the first paying customers came in. The speed of payment was the signal he needed. He contrasted this with previous projects that had no users at all.
“So it wasn't even a product it wasn't an app it was just some back end I was playing around with It was a script on NestJS that I had built Eventually my friends invited me to homecoming I gave a few people the app to play around with And this was probably the first time that my high school friends cared about anything I was working on That was when I realized that there might actually be something here”
Build the Scrappy Backend Version Before Committing to a Full Product
Kishi did not build Social Wizard as an app initially. He wrote a quick NestJS script to solve his own problem, then handed it to friends at homecoming. The moment his peers actually cared about it was the signal he needed to polish and ship it properly.
“niching down was a huge unlock for us actually So I had no clear use case The tagline on the landing page was text to video for everyone which is really not great to be honest And the smart friend actually told me I will have a much easier time uh selling this product if I decide on one particular use case”
Niche Down to One Use Case as the Core Growth Unlock
Before niching, Neural Frames had a generic 'text to video for everyone' tagline that required users to do extra mental work to see themselves as customers. A friend pushed Nico to pick one specific use case. Targeting musicians directly meant visitors immediately felt the product was made for them, making word-of-mouth far more natural.
“I had a screenshot of my not yet published app It was just a design and it kind of blew up There was more than 100 likes and a lot of comments asking you know where can I don't download this app because they thought that it's already live”
Validate With a Design Screenshot in Communities Before Writing Any Code
Ericas validated Kaching Bundles by joining Discord communities of drop shippers and e-commerce Facebook groups before building anything. He posted a screenshot of just the app design — no working product — and it generated over 100 likes with people asking where to download it. That reaction was his signal the product was needed.
“it just seemed to me like there's this huge vacuum in the market where if you wanted to learn back-end stuff you want to learn databases infrastructure it's very hard to do it online”
Identify a Market Vacuum Where Good Online Resources Do Not Exist
Lane was a back-end engineering manager struggling to hire Go developers — only five or six applicants would show up for open roles. He observed that online learning platforms were pushing learners toward front-end, leaving a wide-open gap for back-end education. This direct, first-hand pain validated the market before he wrote a single line of boot.dev.
“step one is spotting trends in the app store...go to the app store and be able to see okay who is currently number one...are there other apps also let's say in the top 20 who are doing exactly the same thing but maybe for slightly different niches Then I go to sensor tower to be able to see okay what's actually the revenue numbers...if I see all of them are doing you know over 100k MR or over 500k MR then I know okay cool there's something here”
Validate Niche Apps With App Store Top-20 Plus Sensor Tower Revenue Proof
Lots validates ideas by reverse-engineering the App Store top charts: find the number-one app in a category, scan the top 20 for clones serving adjacent niches, then cross-check Sensor Tower revenue to confirm multiple competitors are clearing 100K+ MRR. Only then does he start hunting for an underserved niche to port the proven mechanic into.
“I usually validated product by using a single landing page builder named yep.so My only goal was you know to distribute the landing page on my ex channel collect emails from interested people and use the building public strategy I usually consider like a 15% of conversion rate on my landing page as a good bath”
Validate Every Idea With A yep.so Landing Page Gated By A 15 Percent Conversion
Before writing code, Dom spins up a single yep.so landing page, pushes it through his X audience using build-in-public posts, and gates the decision to build on a hard 15% email conversion rate. The numeric threshold turns 'is this a good idea' into a falsifiable test he can run in days, and the captured emails become the seed audience for the first feedback loop.
“When I do my research I make sure the keyword has at least 20% of popularity and 60 or 70% difficulty...I check top competitors and look at their monthly revenue...my benchmark is at least 100 or €200 per month. If the competitor does less...there's not that much money in that market.”
Gate Every Idea Behind 20 Percent Popularity, Sub-70 Difficulty, And €200 Competitor Revenue
Max's idea filter is a hard numeric gate, not vibes. He uses Astro to surface keywords meeting his popularity-difficulty ratio, then verifies on Sensor Tower that the top competitor already earns at least €100-200/mo. Any keyword failing either test gets dropped before he opens an editor.
“If I experienced this pain I could build a better product than my competitors. Also I would care more about it... if you love what you're building you'll put in the effort and put in those extra details to craft a better experience...”
Filter Every Idea Through Your Own Daily Habits So Specs Come From Lived Experience
Pre picks ideas only from activities he personally does — cold plunges, sunlight, posture — so the product specs come from lived experience instead of survey decks. The personal-pain filter doubles as a motivation moat: caring more compounds into better craft, which compounds into downloads and revenue.
“me and a friend worked on it for about a week we got a domain we launched it and then we bought Google ads to get people to start clicking into the domain and immediately people started uploading bank statements which kind of validated the problem”
Build A One-Week MVP And Use Google Ads As The Real Demand Test
Angus skipped pre-launch validation entirely. He and a friend shipped a working MVP in about a week, bought Google search ads to drive targeted traffic, and treated actual bank-statement uploads as the demand signal. Watching strangers convert beats every friend-and-family survey.
“I decided one day to just build a bunch of tiny tools on my own personal website... I built four or five tools that week... Audio Pen's MVP was one of those five tools that I built. It got a lot more love than I expected...”
Ship Four To Five Tiny Tools In A Week And Double Down On The One That Pops
After 15 failed projects, Lewis stopped picking ideas in advance. He shipped four to five tiny tools to his personal site in a single week and tracked which one got disproportionate love on Twitter. Audio Pen popped, so he committed only after the signal showed up — picking the winner instead of guessing it.
“I went on Google Trends I was looking for a keyword such as stop sugar and because for the past five years the trend of those keywords is basically going higher and higher and higher and then I check for the same keywords on Tik Tok and Instagram and I saw that there were a ton of women influencers”
Validate A Clone Niche With Google Trends Plus TikTok And Instagram Creator Volume
David validated the niche switch before writing any code by confirming a 5-year upward search curve on Google Trends, then verifying creator-side supply on TikTok and Instagram. Two cheap signals — rising keyword + active influencers in the niche — were enough to greenlight building a clone targeted at that audience.
“There's two different types of apps — there's innovating new ideas and there's modifying versions of existing ideas. If you're creating a modified version of an existing app then congrats, your app is already validated by other people. Now all you have to do is make some modifications and make it so the app feels like it's your own.”
Split Every Idea Into Modified Version Of A Winner Or A Brand-New Demand Test
Connor splits ideas into 'modified versions' (pre-validated by an existing winner) and 'brand new' (validated by reading TikTok and Instagram comments asking how to solve the problem). For modified apps he skips validation entirely because someone else already proved demand — the only work left is making it feel like yours.
“Pick an idea that's been done before. New ideas are risky, new ideas need validation. If you pick an idea that's been done before you know that people want it, you know that it works. We go and find the idea, we work out how well they're doing despite of a bad UX.”
Only Build Ideas Proven By Incumbents With Bad UX So Design Quality Becomes The Wedge
Mike refuses to validate demand from scratch. He hunts for categories where incumbents are already making money despite poor UX, then out-designs them. The bad-UX-but-paying signal is what makes him claim a zero-failure rate across five SaaS apps — design quality becomes the differentiator, not the bet.
“We will never go after an AI focused business. Too many times you have an idea that relies on something, an API that you do not control, something that you're not in control of which puts you at massive massive risk.”
Avoid AI-Wrapper Businesses Because You Don’t Own The API That Makes Them Possible
Mike's 'can't fail' filter explicitly excludes AI-wrapper businesses because they depend on third-party APIs that can change pricing, terms, or capabilities overnight. He'd rather build boring tools where he owns the full stack than chase sexy ideas that may not exist in six months.
“For Curiosity Quench as an example I posted a video 60 seconds on TikTok. I just point and shoot recorded it talking to the camera and 15 people commented saying 'I need this this is it this is good.' So I kept making videos, the same thing happened, and eventually I realized hey I should probably make this thing that hundreds of people say they want.”
Shoot A 60-Second Selfie TikTok And Count The “I Need This” Comments Before Writing Code
Jack validated Curiosity Quench by filming a single 60-second selfie TikTok describing the idea — no landing page, no pre-orders. When 15 strangers commented 'I need this,' he kept posting; when hundreds said it across more videos, he built. The signal is unsolicited 'I need this' comments, not likes or views.
“Step one we would build for the customer's next problem. So Taskmagic's original customers they were business owners agencies freelancers people who need sales. Step two building something very simple. So we were like okay well let's build like a very simple outbound tool.”
Build For Your Existing Customer’s Next Problem Instead Of Chasing A New Audience
Jeremy validated each satellite tool by asking what his existing Taskmagic customers needed next, not by chasing new audiences. Mail Lead (a cold-email tool) was built because Taskmagic's base of agencies and freelancers already needed sales outreach, guaranteeing built-in demand before a single line of code.
“You don't need a new idea. There's plenty of ideas out there, problems that have been solved that you could improve upon, and while you're improving upon that you might find a niche within that industry. Weightly is a perfect example. I competed with the giants like OpenTable and found a little niche where I can serve the small restaurants that are underserved.”
Skip Novel Ideas And Find The Underserved Niche Inside A Solved Billion-Dollar Category
Joe rejects the 'novel idea' trap entirely. His framework is to pick a solved problem with billion-dollar incumbents, then find the slice they neglect. For him that was small restaurants priced out of OpenTable's cover fees and hundreds-per-month plans — a market the giants couldn't economically serve.
“We just kind of started looking at TikTok makeup videos and looking at the comment section and with these comments we kind of started doing content around this idea... By looking at comment section you really just feel what people are wanting and you just try to come in and solve whatever they're asking for.”
Read The Comment Sections Under Viral Niche Videos To Surface The Exact Pain Customers Beg To Solve
Louie picked the makeup niche because it was huge on TikTok, then read the comments under top videos to surface the exact pains and product questions people kept asking. He turned those recurring asks into content angles before writing a line of code — sensing demand instead of guessing it.
