Normal Outreach is Not Working, So We Made a Bumble-esque Matching Tool for SDRs 📲🙏

We ve been building ReachRobin to solve a problem that most outreach tools ignore: making AI-assisted outreach feel human, controllable, and safe.

Most tools either over-automate or send boring, generic messages that feel like spam, and will be treated like spam: no one is responding to that.

ReachRobin takes a different approach: matching you with leads that are more likely to convert, instead of blasting thousands of cold DMs. Our AI assists with drafting, execution and qualified leads suggestion, but humans stay fully in control of who to reach out to, what and when to say.

I just built my first Next.js app with AI assistance. Feedback wanted! 👋

Hi everyone,

I'm a new indie developer currently learning to code with AI assistance.

I realized that many existing online line counter tools are either ugly or full of ads. So, I decided to build my own as a practice project.

How do you deal with tab chaos while working?

Hey PH folks

I am continually getting caught in the same pattern: I start working on something with good intentions... and 30 minutes later I am overwhelmed with tabs scattered in 3, 4 different contexts (work, learning, "quick research, " distractions). It is the switching back and forth between contexts that really gets to me, not the tasks themselves.

So, I decided to implement a very simple rule: one window per goal.

Foursite: From 2D Floor Plans to 3D Design Options in Minutes: Not Weeks

My co-founder and I are not designers. We re not architects. We ve never held a blueprint or studied color theory. We re just builders who got tired of hearing the same problem over and over.

Interior designers are burned out.

Not because design is hard. Because the logistics of selling design is brutal. A designer spends 32-46 hours creating a proposal. They sketch. They source materials. They create mood boards. They render concepts. Clients look at 2D floor plans and say I don t get it. So designers start over. And over.

Founder Introduction: Fighting "Survey Fatigue" with AI (and why NPS is broken)

Hi Product Hunt!

I m the co-founder of SeekWhy.ai, but before that, I was a technical lead who sat through too many "All-Hands" meetings where management tried to explain away a bad NPS score.

I realized that traditional surveys are broken because they give you a number (e.g., "7/10") but zero context. HR teams end up over-correcting for a "loud minority" while ignoring the "silent majority" because manual follow-up doesn't scale.

What I m building: We ve built an AI-first platform that uses an AI agent to dynamically "interview" employees during the survey. If one person mentions a specific friction point, the AI cross-validates it with the next person in real-time. It s the first tool that can actually tell you: "Is this 3 people or 300?"

I built an interval timer because every other made me crash out.

I train a lot HIIT, strength, functional fitness and I've tried every interval timer out there. They all have similar problems! Too many screens to set up a workout, clunky UIs you can't read mid-set, or they want you to create an account just to start a timer.

So I built FireTime.

It's a dead simple interval timer where you name each interval, set the duration, hit go. That's it. No account, no onboarding flow, no bloat.

A few things that make it different:
Build a full custom workout in seconds
Each interval gets its own name and duration
"Up Next" preview so you know what's next.
Audio + haptic cues so you can put your phone down
Pre-built templates for Tabata, EMOM, 5x5 and more
Apple Watch app included
Dark UI that's actually readable when you're sweating

Financial Calculator 7.10

The payment section has been corrected, making it possible to properly verify payments.
