“From those three to five domains you're going to look for niches that already have successful SaaS tools. If they're already making money, that means the market exists. The key here is that you don't need a unique idea — you're just going to execute better in a proven market.”
Validate by finding niches where SaaS competitors are already making money
Hassam explicitly rejects the unique-idea trap. Validation comes from existing paid competitors (Sensor Tower, Google Search Console competitor data), not novelty. Once a niche has incumbents pulling real revenue, the only remaining job is to out-execute them with deeper domain knowledge or a tighter partner channel.
“I ended up talking to probably a 100 plus founders that were working in the B2B SAS industry and I think the unifying concern was yes this was a really painful problem people hated creating product demos people hated the sound of their own voice and that's when I realized hey there's something to run with here”
Talk to 100+ founders before building to confirm the problem is painfully real
Joseph interviewed over 100 B2B SaaS founders before writing a line of code, looking for consistent emotional language — not just a nod of agreement. The repeated, specific signal (hating demos AND their own voice) gave him the conviction to build rather than guess at a painful problem.
“I pushed out a tweet and basically said I'm going to build an open source alternative to Docsend and it went just like crazy within a couple hours it got like 40,000 views lots of people mentioned that they would love to see this as an open source project so over the weekend I actually built it.”
Single tweet got 40K views validating open-source Docsend before any code
Mark used a single tweet as a demand test before investing real engineering time. The 40K-view response and explicit enthusiast replies confirmed both the problem and the open-source angle, removing guesswork from the build and giving him the conviction to sprint a weekend MVP.
“on Superwall we saw that a lot of people were converting to the trial but then nobody was staying after. two numbers that stuck out for us: 45% conversion to trial but then only 13% conversion from trial to paid. what does that mean? everybody wondered what we were selling but the product was shit”
45% trial rate but 13% trial-to-paid means product failure, not marketing failure
High trial opt-in with low paid conversion is a signal that the value proposition is compelling but the in-app experience fails to deliver. Splitting the funnel into these two metrics gave them a precise diagnosis — the problem was product, not awareness — before they wasted more marketing budget.
“i basically made a fake product demo and it got 80k views. there were people literally begging us in the comments to build this app and so we had to build it as soon as possible”
Post fake TikTok demo with 80K views to validate idea before writing code
Using AI footage and stock clips to simulate an app that didn't exist, Alejandro validated demand before a single line of code was written. The 80K views and 500+ comments begging them to build gave a pre-sold audience and eliminated all guesswork about whether to invest development time.
“From my past startups I was always trying to make something unique, something that doesn't exist, and I always ended up building something that people don't really need. Here we intentionally got something that is a little bit tested. We said okay, this is a validated business model, we want just to make it much better and much simpler.”
Copying a validated idea beats inventing something nobody needs
After 15 years of failed startups, Anton reversed his strategy: instead of chasing novel ideas, he found an existing market with clunky players and out-executed them on simplicity. This deliberate choice to compete on UX rather than concept differentiation was the turning point.
“I went to Reddit, I checked the subreddit of notion and search for keywords like sheets, Google sheets, excel, CSV — all related keywords to what I was trying to build and validate — and I found a lot of people trying to export the information from notion into sheets.”
Validate by searching Reddit for demand before writing a line of code
When Notion released their official API, Leandro spotted a gap but didn't assume demand existed. He went straight to Reddit and searched problem-adjacent keywords to confirm real user pain before committing to build anything.
“After about three and a half months I had built out all of the core functionality that members of the community were just straight up telling me about. At that point I messaged the moderator and said 'Hey are you still okay with me doing a top-level post?' They said yes and I went ahead and posted and it blew up.”
Three months of weekly comments validates product and earns a viral top post
Anish spent 3.5 months responding in weekly comment threads on Reddit, collecting real feature requests from his target users. Only after shipping that feedback did he ask a moderator for permission to make a top-level post, which then went viral and became his primary growth event.
“I created a completely fake demo for this product because the product wasn't there yet and put it on this landing page. I think it's the most low-effort way to validate the idea because I wanted to find out if people would actually pay for this.”
Fake demo landing page validates buyer intent before writing any code
Joseph built a minimal landing page under an existing warm domain before writing a single line of code. He used an AI-generated fake demo from ElevenLabs and a Calendly link as the only call to action, letting organic search traffic drive real buyer conversations.
“Don't say 'Please pay for my non-existing solution.' The better way is deliver as much value as you can and give them a 100% refundable deposit offer — say $500. The buyer gets full access to your product once it launches.”
Refundable deposit framework collects real payment before product exists
Teemo outlines a four-step deposit framework as step four of their validation playbook. Rather than asking for a subscription to something that doesn't exist, framing payment as a refundable deposit lowers buyer resistance while still confirming real intent. They collected $500 before their first line of code was written.
“We launched on Product Hunt. It got us a couple hundred installs. Two of those installs converted to subscribers. At which point we knew we had validated the product. We knew that we had something that people were willing to pay for.”
Validate Willingness to Pay With Only Two Paying Subscribers
Steve didn't need thousands of users to feel confident — just two paying strangers proved real willingness to pay. A Product Hunt launch served as a zero-budget validation gate before committing to paid acquisition. This forces founders to confirm demand before spending money on growth.
“we initially built as an internal tool and it crushed for us Then we did a beta test where I invited several friends which are also agency owners as well And when they both closed like between them three five figure clients within two weeks of using the tool I really thought we really had something here”
Build an Internal Tool First to Validate Before Going Public
Ivan validated Lancer by using it inside his own agency before showing it to anyone else. A small beta with trusted peers who quickly landed real clients gave him undeniable proof of value, removing the guesswork before committing to a full product launch.
“word of mouth is consistently one of our top five attribution sources so like on our customer attribution thing people will just type in friend so you know people actually like the product but if you have something that's truly original and solves a pain point especially around an emerging trend people will notice if you're first to market with something”
Treat Strong Word-of-Mouth as Proof Your Product Solves a Real Problem
Tracking attribution revealed that a significant share of Faceless Video's users came from friends recommending it — a signal the founders treated as proof the product genuinely resonated. Being first to market on an emerging trend compounded this effect, because early adopters naturally evangelized to peers who faced the same pain.
“I came across this app called Praycreen that blocked your phone until you prayed. And with the new insights I had I looked at the design I looked at the features the way they were executing their distribution and I said you know what I can do a better job than them.”
Find a proven app and execute its distribution better than anyone
Matt didn't invent a new category — he found an existing app with proven demand and studied its weaknesses. By benchmarking a competitor's design, features, and distribution, he validated the market before writing a single line of code. Copying what already works and improving execution is a faster path to product-market fit than starting from scratch.
“people don't really adopt that, that product needed to provide like access, they needed to credentials to connect to your database... without any credibility and trust from the engineers we said like all right it's too tough”
Pivot when developers refuse to trust your app with their credentials
Jonathan's first product failed because it asked developers to hand over database credentials before any trust was established. He pivoted to ChartDB specifically because it required zero credentials and no local install — removing the friction that was blocking adoption. If your ICP has a deeply-held constraint like security skepticism, build around it from day one, not as an afterthought.
“I just look for challenges I have... I was putting my tweets in spreadsheets every night and reviewing my tweets so I can figure out what's working... odds are if you have that challenge someone probably has it as well.”
Build software that solves your own daily frustrations to find real demand
Alex validated Creator Buddy by solving a problem he personally lived with for years — manually tracking tweet performance in spreadsheets. This ensured genuine demand from day one because he understood the pain deeply, not theoretically. His own problem was the market signal.
“the idea of a database came to my mind and I just started building it out because it's something I'd use myself and I figured with AI I could turn this into a fully-fledged SaaS if enough people wanted it”
Build something you would use yourself before asking anyone else to
Polus did not survey potential customers or run ads to validate. He identified a tool he personally needed for his own creator-led work, built it, and treated his own conviction as the first signal. The $20-30 sales on launch night confirmed what he already suspected — the market existed because he was the market.
“We're not looking for apps that aren't making any money that's not great we're looking for pre-validated ideas so increase that asking price to at least 300,000 or you can filter by annual recurring revenue.”
Filter business broker listings for pre-validated ideas worth copying
Adrian's framework turns Acquire.com into a validation machine: if a SaaS is listed for $300K+, real money has already been proven in that market. Rather than testing a hypothesis, you're cloning a demonstrated outcome — cutting years off the validation phase.
“We don't understand why you haven't charged your users.”
Turn a Rejection Email Into a Weekend Sprint and Get Paid Users
YC's rejection note flagged one concrete gap. Saba and his co-founder spent the weekend implementing monetization, landed 20 paying customers, and emailed YC by 9 a.m. Monday asking for reconsideration — converting a rejection into their first real validation signal.
“I first tried to validate the idea organically and just from that I got $1,500 MRR or something like that — once I got to this point I knew the idea had potential.”
Validate Organically First Before Spending a Single Dollar on Ads
Nico used free channels to confirm real demand before committing ad spend, reaching $1.5K MRR as his signal to scale paid traffic. Only after proving willingness-to-pay without spending did he launch Facebook ads.
“Validation is not necessarily a specific strategy — it's do you want to validate.”
Validation Means Being Willing to Let Your Idea Die
Most founders skip validation not because they lack a framework but because they're emotionally attached to the idea. Jordan's core warning: protect your idea from the world and you'll never know if it works.
“Get manual tasks that people currently pay for which could be significantly enhanced or substituted by existing or imminent generative AI.”
Find Manual Tasks AI Can Replace Before Anyone Else Does
Ramsri spotted quiz creation as a paid, labor-intensive workflow in 2020 and waited for the AI to catch up. Tracking the frontier of what AI can newly do is itself a product-ideation strategy that finds pre-validated demand before tools exist to automate it.
“There used to be a website called the Woo Commerce ideas forum and we chose an idea that lots of people were voting for.”
Mine a Public Ideas Forum to Validate Demand Before Building Anything
Katie's first plugin came directly from a public forum where real users voted on missing features — pre-validated demand with zero customer interviews needed. Finding a forum, marketplace, or community where your target users actively request features collapses validation time to near zero because the votes are a live signal of willingness to pay.
“Duckmath's sitting here and it's been getting all this money i've been doing nothing to it so why not start actually marketing it”
Unexpected Passive Revenue Days Are the Signal to Start Marketing
After two years of low-effort posting, a single $240 passive day revealed that the asset already had real pull. Maddox used that revenue signal — not a plan or a gut feeling — to decide where to double down. Following the money rather than the idea that seems most impressive is what unlocked the growth phase.
“The product was super buggy — for me that was like the ultimate proof: if they pay for this buggy product, there's really an opportunity here.”
Paying Customers on a Buggy MVP Is the Only Proof That Actually Matters
Fernando launched AI Carousels on Product Hunt and five users paid despite obvious bugs. He treats willingness to pay through friction as a stronger signal than signups, waitlist interest, or positive feedback — any of which can be polite noise. Getting paid on a broken product means demand is real and it's time to double down.
“Your app should be the best one for one specific person — it will be absolute disaster for everyone else.”
Your MVP Must Be Better, Faster, and Cheaper for One Specific Person
Nick's framework explicitly requires the MVP to win on three axes simultaneously for a single ICP, not to appeal broadly. This focus means you can outcompete incumbents who serve everyone adequately but no one perfectly. Deliberately being a 'disaster' for most people is the strategy, not a flaw.
“I made a video about that and it got like 1 something million views and that strategy that I brought to the internet has since been repeated so many times that it's referred to as the compare lists method.”
Validate Demand by Making a Video About the Problem Before Building Anything
Ben discovered the demand for a safer Instagram unfollower tool by creating a video explaining a manual workaround — not by building anything. The video drove over a million views and sent traffic to a competitor's tool, proving massive latent demand before he spent a dollar on development. He then spent 4 years watching the idea mature before building it himself.
“I email them all and I offer them 90% discount on a pre-sale before I build anything and then if I get five sales I build the first MVP.”
Sell Before You Build Using Presales to Confirm Real Demand
After generating 100 waitlist signups, John offers a 90% discounted pre-sale before writing a single line of code. The five-sale threshold acts as a minimum viable signal that real money — not just interest — exists. This filters out ideas that attract curiosity but not commitment.
“Provide solutions to problems your audience already have. This really works well because these are problems you probably already have.”
Build in a Niche Where You Have the Problem Yourself to Validate Demand
Jackie's approach to both content and product validation starts with problems he personally encounters, then explores solutions publicly on YouTube. If he has the problem, his niche audience almost certainly shares it — and the video itself becomes the validation experiment, with the call-to-action link revealing real purchase intent. This removes the need for surveys or waitlists.
“Step four is to charge early even if the price is low. We charged during the beta and I guess that really validated that customers were willing to pay. There's no point chasing that idea if in the early stages no one's willing to pay for it.”
Charge During Beta to Prove Willingness to Pay Early
Rather than running a long free beta and hoping for eventual conversion, Thomas introduced a $25/month subscription right after stabilizing the MVP. The first paid notification on his phone was a concrete signal that the product solved a real problem worth money. Charging early filters tire-kickers and surfaces the truth about demand before you invest months of further development.
