Hi Product Hunt!

I'm Oanh, Marketing Lead at Pion, a small tech team (under 20 people) based in Vietnam. We build software for individuals and online businesses, from fintech and payment tools to cloud services.

Hey everyone,

There are 27 EU member states and 1 EU e-invoice standard, and so far I've implemented 21 country-specific versions of it. XRechnung in Germany, Factur-X in France, CIUS-RO in Romania, HR-CIUS in Croatia, and so on. Same norm, different rules, and the buyer's side checks them. That's the rabbit hole I fell into.

I'm Taylan (most people call me Tay). I'm german and study Computer Science, work as a working student in AI & integration, and was a software developer before that.

Alongside that, I co-founded Vera with a German tax advisor. The company is still being registered, so it's early days. Germany phases in mandatory e-invoices from 2027, and Vera picks the right format from the buyer's country, tests it against the official German validator and hands the bookings over to the tax advisor. There's also an API and an MCP server, so AI assistants can create and check invoices directly.

I'm in the back half of my career, the first half spent in sales-related roles and Sales/CS leadership. I was always a technical person, but never a developer or engineer. Then AI hit, I leaned in hard, knowing that this was a race to learn before other people figured things out. Long story short, AI lowered the developer/engineer bar, and I'm now head of AI Innovation at my company and loving it. Who knows where this leads, but I'm loving getting paid to play with AI and build Innovation plays as my full-time job.

Hey everyone

I'm Mohamed from rural Egypt. I build everything myself code, design, support, all of it.

Last month I discovered my AI agent was quietly ignoring the skills I spent hours writing. Small structural mistakes I couldn't see. So I did what any stubborn maker does: I built a doctor for it.

trigger-doctor is a free, open-source tool that reads your SKILL.md the way your agent does and tells you exactly why it's being ignored.

Most intros start with a job title. Mine starts with a date: September 28. That's when my friend Josh asked me to run marketing for Vresk, the AI workspace he built, with launch set for this week. I said yes before I'd thought about what it meant.

What I've learned in those 9 days, in case it helps anyone with a launch coming up:

Email real people, one at a time. We reached about 70 small creators by hand, each email opening with something about their actual work. No mass tool. The replies came from the ones where I'd clearly read their stuff.

Check your email setup before you send anything. Our domain was missing a record and the first batch bounced as spam.

Hi everyone,

I studied computer science, but my career went into textiles, and I stayed there for 22 years. Code was always at the back of my mind.

When AI tools took off in 2025, I started building again, first just as a hobby. Now I have a few small apps in the pipeline. The first one, ClipQuery, went live this month: you ask a question about a YouTube video and it shows you the exact moment where it's answered. (ClipQuery's profile on Product Hunt | Product Hunt)

Hi PH brothers & sisters,

I'm Venkat! In 2015, I co-founded my first startup. We launched before we were ready, tried to reach everyone instead of a specific audience, and our co-founder relationship broke down. The startup didn t survive.
