I built Uplyft, a motivational messaging app for parents and families. No co-founder, no backend experience, no real plan. Just Claude and a birthday launch date in July.
Got rejected from a pitch competition in 24 hours this week. Walked away with a one-pager.
Check it out at app.uplyftlife.com. Honest feedback welcome.
Over the past year, we've been building ButaGYM OS, a platform for gym owners to manage memberships, payments, member access, staff, and day-to-day operations from one place.
I'm an independent developer and software engineer from China. I spend most of my time building practical tools with Python and Chrome extensions solving real problems I run into during work and daily life. This is my fourth Chrome extension, and like the others, it was born out of a personal need.
If you've ever managed multiple accounts on the same website, you know the drill:
Log out of one log into the next repeat. Every. Single. Time.
Have you ever wanted your high-end laptop to sound like a 1998 Honda Civic with a blown-out subwoofer? Probably not, but now you can!
Blown Speaker Simulator is a novelty Chrome extension built to test the absolute limits of Chrome's Manifest V3 and the Web Audio API. It captures your active tab's audio, isolates the low-end frequencies, and applies heavy digital distortion in real-time.
How it works under the hood: Since MV3 service workers don't support AudioContext natively, the extension uses chrome.tabCapture to send the media stream to a persistent Offscreen Document. Down in that layer, a BiquadFilter isolates and boosts the bass (+28dB), and a WaveShaperNode applies real-time clipping without perceptible latency.
I built this entirely with the help of AI, experimenting to see if I could create a complex audio graph without any prior audio engineering background.
We all know the deal: Google and Meta ad dashboards are designed to make you spend as much as possible. For makers and small business owners, running ads often feels like a gamble you set everything up, hit "launch," and pray your entire budget doesn't vanish by lunchtime with zero results.
We are building Solvera to change that. Our goal is to automate the tedious parts of advertising and make pro-level marketing accessible to everyone, without the need for expensive agencies.
I've seen a couple of influencer platforms around ecommerce, but very little or non exist for backing founders - closest is probably https://gigastar.io/. So I've been toying with an idea and finally built a rough version at kovant.club (bigger current concept at https://kovant.club/home).
The core concept is a closed club where founders get distribution without upfront cash, and influencers earn a royalty on the actual lifetime value of customers they refer for up to 2 years. If the startup wins, the influencer wins big. If not, they still get 1/10x of the delivered value. The key is an SDK that tracks every referral's LTV over time primarily scoped to 3 months (still working out the maths).
The signal is intentionally high: founders would need a 60%+ score on something like https://www.build-check.com by @german_merlo1 and must also be referred by an existing influencer/founder.
Would love to get your honest takes. Of course it doesn't work for all influencers/founders but I feel it will genuinely help a lot of founders who have real value to offer. Two questions I have for PH founders:
Genuinely curious how bad this problem is for other people, or if it's just me.
I track roughly how much time I lose every week just copying stuff out of emails into HubSpot names, companies, deal details, next steps. It's not hard, it's just constant, and half the time I forget to log something until it's too late to actually follow up on it.
I ended up building a small AI tool for myself that reads sales emails and call notes and pulls that info out automatically, with the source sentence and a confidence score attached , with overall analytics so I'm not just trusting a black box. Still rough, still learning what actually matters day to day.
But I'm more interested in the general question here: for people who use a CRM daily, is manual data entry actually a real pain point for you, or have you already solved it some other way (Zapier, native integrations, just a good habit of logging right after every call)? Would love to hear how others handle this.
