Built a PR marketplace because I hate quotes.

My biggest pet peeve is not seeing the prices and the conditions right out front. What do you mean I need to call you to get a quote? What next? A retainer, proposals, more back and forth, and an absolute waste of time. If the product is good, why hide it? Working on adding more, but I have around 1500 media outlets that you can get placements in. You can check all their prices on essentras.com . Right now, there's a free real media placement worth $250 good for getting the ball rolling a...

How do you guys drive traffic to your applications?

So I'm trying something different this time. I built meaty.me — a dead-simple meeting note taker that runs in your browser. No app store, no installation. Just open it and tap record, save your conversations for later review. It's a tool not a SaaS. Add it to your home screen if you like that native appfeel. I’ll top up your quota in exchange of some feedback Roast it gently 🫠 meaty.me

I built a simple lawn & garden calendar

It’s called Garden Calendar: Lawn Care and it’s a simple MVP, not a big AI assistant or complex garden planner. What it does right now: log fertilizing, spraying, mowing, watering and other garden work track how long treatments stay active see upcoming tasks and recent entries browse your season in a calendar create reusable product templates for things you use often ...

Built a code debugger that uses your own editor to scan your codebase — no paste, no upload, no privacy risk

Most AI code tools ask you to paste your files in or give access to your repo. I wanted to build something different. Code Reasoner works like this: You describe your problem in plain language It generates a structured discovery prompt you run inside Cursor, Windsurf, or VS Code - anything Your editor scans your own codebase and returns a diagnostic report You paste the report back — and a council of specialist AI models audits it in parallel You get a surgical fix prompt with exac...

Amawish Update #9: Thinking of going the APP way

It has been a month since my last post, so here we are again =) A small strategic question this time. So far, Amawish has been built as a web app. The idea is simple: help people create personalized birthday cards with a small historical twist from the recipient’s exact birth date. The web route made sense at first because SEO matters a lot for this kind of product. People search for things like birthday card maker, personalized birthday card, printable birthday card, and so on. But the ...

How to get yuor first 1,000 Customers, A Playbook

I coach founders for a living and I've watched this same movie a few hundred times. Someone's stuck in the single or low double digits on customers. They're sure it's a marketing problem. They ask which channel to run. Cold email? SEO? Ads? Reddit? Wrong question. I had a client once. B2B SaaS agency. Built the product perfectly, launched to silence. He tried cold email. Then a branding agency. Then he fired people. Then he blamed marketing. Months of it. He finally picked up the phone and...

I have built something but not sure it'll get customers? Drop it and i'll give you the honest read

For the folks who've actually built their business, drop your project (one line on who it's for + what it does, link if you want) and i'll give you the honest read most people won't. The riskiest assumption your thing rests on and why people might not be paying yet. Usually it's not the product, it's that the buyer or the distribution isn't nailed. So no "It looks great!" fluff. Please drop them in the comments, I will go work through them.

Underwater photos come out blue — I built a physics-based fix (no presets). Free browser demo inside.

If you've taken a photo more than a few meters underwater, you know everything turns blue-green. Water absorbs red light first, so by ~10m the reds and oranges are basically gone. Most fixes are manual sliders or one-size presets you end up fighting per photo. I'm an iOS dev with a photography background, and I built ScubAI to fix this with physics instead of filters. Instead of guessing, it works out what the light actually looked like at your depth - from your depth + how clear the water was...

I rewrote my landing page 5 times trying to explain my product. Then I deleted it entirely.

Hi, I've been building a social platform for the past few months, and I kept hitting the same wall: people see it and ask "wait, what is this?" or "what's the actual value here?" So I did what most of us do, I rewrote the copy. Long version, short version, feature lists, benefit-driven headlines. Five rewrites, same confused reactions every time. Eventually I got annoyed and just deleted the landing entirely. I started to think that if the product can't explain itself i...

the most common (and invisible) reason early startups lose signups

been talking to a bunch of early founders lately and the same thing keeps coming up. the product's genuinely good — but a stranger lands on the homepage and can't tell what it actually does in the first ~7 seconds, so they bounce. and the brutal part: the people who leave confused never tell you. you just see a high bounce rate and blame traffic. it's almost never the traffic. you're too close to your own product to see the gap — all the context is in your head, so the headline that's obviou...

A few months ago, I built and launched BinaryTranslator.org - a free web suite for developers and students to convert text to binary, hex, decimal, and octal. It got some good traction, but as I was using it myself during development, I noticed a friction point: Constantly opening a new tab, navigating to the site, pasting a string, and copying the result back was completely breaking my workflow. So, I decided to package all that functionality (and more) into a lightweight browser extensio...

I'm a terrible designer, a worse writer, and can't edit video to save my life. Here's how I finally built something that worked anyway

I'm 36. Most of my friends own apps or ecommerce stores, and for as long as I can remember I wanted to be like them. Or at least pull in some real money from something digital instead of staying salaried forever. So I tried. A lot. Over the years I had 4 ecommerce sites, one Amazon FBA, 3 apps, and I put out 2 Amazon KDP books. Most of it worked, technically. It just barely worked. A few hundred bucks here and there, and three of them flopped completely. The worst part wasn't even the money....
