Built a system that transformed one business, now I’m stuck trying to sell it to others. What am I missing?

About a year and a half ago, I started working with a car rental business to build them a custom management system. They were drowning in paperwork, manual tracking, and all the chaos that comes with running a rental fleet. I built the system step by step with their ideas and guidance + my skills. The result? It completely transformed how they operate. It saves them hours every day, keeps their bookings, fleet, and customer data organized, and they regularly tell me they couldn't go back to the ...

i scraped 21,000 b2b software companies and found 25 saas apps people hate but can't quit. here's the full list to rebuild with ai:

most people pick a saas idea by guessing what's missing. i did the opposite and went hunting for software people already hate but won't leave. pulled 13,311 capterra companies and 7,989 g2 profiles . filtered for three things at once: 200+ reviews , negative nps , and sentiment that's actively declining year over year. then i cut it to the boring shit nobody wants to touch. dental software. construction accounting. medical emr. legal practice management. the stuff that sounds painful to...

I developed an ad-free/free vaccination tracking app for my pet because I kept forgetting its vaccinations: Pet Tracking

Hello friends, While keeping track of my cat's vaccination schedule and medications, I realized that most apps on the market are full of ads, require constant registration, and are cumbersome. So, to both solve my own problem and benefit other pet owners, I developed a completely independent (indie) mobile application: Pet Tracking. The most important aspects I focused on while developing the application were: 🔐 Local-First by Default: You don't need to create an account, provide an email ...

Built a finance dashboard for founders after nearly missing payroll. Here is what I learned.

Founder here, full disclosure I built what I am about to mention. About a year ago I was running our startup and had no real idea what our burn rate was on any given day. I thought I did. I had a spreadsheet, I had rough numbers in my head. But the actual picture? Not clear at all. End of one particular month I nearly didn't have the full picture to confidently make payroll decisions. Not because we didn't have money. Because I genuinely didn't know where we stood in real time. That shook me...

Do all ideas need to become SaaS?

Lately I’ve been wondering whether developers force subscription models onto products that don’t really need them. Some software feels naturally recurring. Others feel better as one-time purchases or simple utilities. How do you decide which bucket a product belongs in?

A skeptical Reddit comment became my entire product. Here's the validation lesson.

A few weeks ago I posted an app idea here on Reddit (an AI that gives outfit feedback) asking if it was useful or a gimmick. The replies were mixed, but the single most valuable one was a skeptic who said: "AI sycophancy will just flatter you regardless of how silly you look." That one comment did two things I didn't expect: It killed my generic version. I was about to build "AI stylist gives nice feedback", which is exactly the sycophantic thing he was des...

Building a SaaS around a problem I personally experienced

I've always been someone who trains regularly, but I noticed something that felt a bit contradictory: I'd go to the gym for an hour and then spend the next 8–10 hours sitting at a desk working. By the end of those days I'd often feel stiff, sluggish, and low on energy despite technically being "active." That led me down a rabbit hole of research into sedentary behaviour and something called movement or exercise snacking kept coming up ! These are short bursts of movement performed ...

Built a startup on nights and weekends. Just discovered my contract may claim ownership of it.

I’m in a situation that’s starting to make me nervous and I’d love to hear from anyone who has been through something similar. I’ve been working on a software startup in my spare time for quite a while now. It’s something I built myself, outside of work hours, on my own equipment, during evenings and weekends. The complication is that I currently work for a company in the tech/security space. My product is not the same as what my employer does, and it’s not competing directly with them, but ...

I delete my app every 2 weeks out of frustration

be honest with me. Some weeks I’m super motivated. I wake up early, code for hours, and feel like I’m finally building something great. Then other weeks I open the project, look at the zero growth on my analytics, see the same bugs and empty Stripe dashboard… and I just want to delete the entire fucking thing. I’ve already restarted this project from scratch 4 times this year. The emotional rollercoaster is actually insane. One day I’m convinced this will work, the next day I feel like a c...

Hello ya'll creative people. I am stuck in a rut. We all know that building the SaaS is the easy part, and marketing is the hard bit, where most start-ups fail. Any recommendations for marketing books? I want real-life recommendations, not "I've heard that one is good" . Thank you all in advance!

Your SaaS is going to die from the agent layer, not from a competitor. Here's the math.

Ok not here to say "agents will replace SaaS", here to show mechanism behind it, & Here is that specific mechanism. Your SaaS product has a UI that humans navigate. That UI costs you $200,000 to $400,000 (Not talking about vide coding here) per year to maintain and improve based on your typical Series A engineering allocation. The UI is not your value. Your value is the data model, the integrations, and the business logic underneath it. AI agents do not care about your UI. Th...

I’m jealous of every “I hit 3k MRR” post

yeep ! i’ll admit it. Every time I see those posts “Just hit $3k MRR in 3 months ” I feel genuinely happy for the person… but deep down I’m also jealous as hell. Meanwhile I’m sitting here after 8 months grinding every day with only $68 MRR. I keep asking myself what I’m doing wrong. Am I building the wrong thing? Is my marketing trash? Or am I just not good enough? I know comparison is the thief of joy, but it’s hard not to feel like shit when everyone only shows the highlight reels. The ...

Is trust the hardest feature to build in security SaaS?

I’m building a SaaS in the online document sign / secure vault for files ( with a windows application that i don't known how to promote, make people trust to install ). My app is called esecuriser.com One thing I’m realizing is that security SaaS is very different from most SaaS categories. If you build a scheduling tool, analytics dashboard, or screenshot API, people can try it and decide if it works. But if your product handles sensitive documents, signatures, encryption, or confidential...

Anyone using voice ai customer service in hotels? How's it working out?

We're a mid-sized hotel group with about 8 properties and honestly our front desk teams are getting overwhelmed with basic guest requests - room service orders, wake up calls, checkout extensions, stuff like that.

I keep hearing about voice ai customer service solutions but not sure how well they actually work in practice, especially for hospitality where guests can be pretty demanding about getting real human interac...

What’s your motivation to build?

So the reason why I'm asking that is because I want to tell you guys about Breadmaxxer . This is a budgeting app that I built because of my own frustrations that there hasn't been any incumbent out there that is trying to tailor their services for tipped workers. It kind of makes sense because this is a small segment in the market compared to every other type of worker out there. Honestly it's been really fun building it and I just wanted to tell you guys to check it out if you want to. It wo...

I'm testing my tarot app's onboarding funnel one cheap ad at a time. Two rounds in.

I run a daily tarot app that helps people self reflect and I'm validating the funnel one small experiment at a time. I think this is the best way to test what ads work out for distribution purposes. Wanted to share this as it may help other founders with their product. Round one: $5 on TikTok, pointed at my landing page, testing a few content types. It bought a few thousand page views and zero card pulls. People looked. Nobody touched the product. So I figured that users may not want a landin...

Our ai feature went down in the claude outage yesterday, right as i'd spent two weeks making it cheaper

Small b2b saas, about 15 of us, the product has an AI feature that sits inside the paid plan. I own both the spend and the infra, which mostly means i hear about it when either one goes sideways. For the last couple of weeks i'd been heads-down on the cost side. The inference bill had grown into a real piece of our gross margin instead of a rounding error, and most of our calls were going to claude purely out of habit. So i went through what the feature actually does and pushed the cheap work,...

We launched an AI review tool. Founders ignored the main feature.

Hello guys! A few weeks ago I launched an MVP called AppRoast.app The original idea was simple: Use AI to analyze App Store / Google Play reviews and generate a brutally honest “roast” explaining why users hated an app. But after talking to founders, indie devs and PMs, I noticed something unexpected: Almost nobody cared about the roast . They kept asking questions like: “What changed after our last release?” “Why did ratings suddenly drop?” “Did sentiment change this week?” “...

I built a marketing workspace

I built a marketing workspace to replace my scattered tool stack. Looking for beta testers. Every day looked the same. Projects in Notion. SEO in Ahrefs. CRM in one tab. Analytics in another. Content planned somewhere else entirely. Multiple logins. Everything scattered. No real overview. Half the workday wasn't actually doing the work. It was just holding all the tools together. So I started building Wemify. Originally just for myself. But the more I built, the more I realized this...
