Join us in Warsaw on September 17-18 for Agent Conf 2026.

We're excited to help spread the word on this one: two days bringing engineers together to explore how software development is changing with agents - from vibe coding and debugging agent behavior, to orchestrating multi-agent systems in real teams and products.

The program features AI engineering leaders from companies like eBay, Meta, Allegro, and more.

If you're building with agents, experimenting with agentic workflows, or trying to understand where software engineering is headed next, this is worth your time.

Book your spot: https://www.agent.sh/

🚀 Join us on September 4th for GTM Tech Week x OpenAI Meetup: The Future of Agentic GTM in Warsaw - co-organized by START Warsaw.

Revenue work is being rebuilt. Sales, growth, marketing, customer success, and revenue operations are moving from isolated AI assistants toward agentic systems that can research, reason, create, and execute across the revenue lifecycle.

Building on the energy of GTM Tech Week, this evening combines concrete Codex and ChatGPT demonstrations with operator insights, startup perspectives, an honest panel discussion, and valuable networking.

What we'll explore:
🔺 Where Codex and ChatGPT can change knowledge work inside revenue teams
🔺 How agentic workflows reshape research, sales, growth, customer success, and revenue operations
🔺 How startups and established companies can move from scattered AI experiments to repeatable operating systems
🔺 What founders, operators, and investors need to build, adopt, and support next

📍 Just Join IT, Warsaw
🗓️ September 4, 2026 - 18:00–21:00 CEST
This is a selective event - registrations are approved on an ongoing basis.

Great fit for founders and startup leadership teams, growth/sales/marketing/customer-success/revenue-ops leaders, and enterprise leaders redesigning revenue work with AI.

We're excited to announce that Start Warsaw is now an official partner of AlienBazaar hardware hackathon!

Sept 25–27 in Warsaw, 20 engineering teams from across Europe will come together to connect 20 hardware devices into one interconnected robot ecosystem — building the future of EU robotics, live.

This isn't a single-device demo. It's a live convergence of everything robotics has to offer, under one roof: industrial robot arms, a wide range of robotic manipulators, robot dogs, hexapods, humanoids, drones, underwater drones, and AR - all connected into one interoperable system.

20 teams. 20 devices. One weekend. One interconnected ecosystem.

Proud to support this mission. Join the movement.
Registration closes September 15 👉 alienbazaar.com

🚀 Join us on September 4th for Codex Build: Future of Knowledge Work in Warsaw - supported by START Warsaw.

100 chosen founders, engineers, and operators will spend an afternoon doing real, hands-on building. After a short welcome and a live Codex demo, most of the time will simply be about building.

Pick one track:
🔹 Reinvent Go-To-Market — new ways to scale revenue
🔹 Reinvent Internal Work — an agentic co-worker for research, ops, or collaboration
🔹 Reinvent the Customer Journey — faster, smarter, more personal interactions
Work solo or in a small team. Bring a workflow you actually want fixed, build a working prototype with Codex, and demo it to the room by the end of the day.

📍 Just Join IT, Warsaw
🗓️ September 4, 2026 — doors at 14:30, program 15:00–18:00 CEST
👥 Capacity: 100 — registration is selective, spots are limited

Great fit for founders, technical builders, operators, and strong student builders ready to tackle a real challenge. Bring your laptop and one workflow worth improving.

And… that’s a wrap. 🚀

What started as an idea a few months ago turned into a room full of 78 people building.

And not just any people. They were all selected from a pool of almost 300 applications.

For several hours, teams worked on real challenges with support from mentors, founders, and partners. Some met for the first time that morning. By the evening, they were pitching products they’d built together.

That’s pretty cool.

Huge thanks to everyone who spent their Saturday with us. To every participant who shipped instead of overthinking. To our mentors and judges for pushing teams in the right direction. And to openai solidgate_tech, boski.ai, and all of our partners for making this possible.

This was the biggest event we’ve organized so far, and seeing the room full from start to finish made all the late nights worth it.

Warsaw has no shortage of people who want to build.

And it’s only the beginning.

Due to technical issues, we were required to change OpenAI x START Warsaw Hackathon location to Solidgate’s Office.

See you there!

OpenAI x START Warsaw Hackathon is happening. 🚀

100+ builders.
Real business problems.
7 hours to build something that actually works.

This will be the second OpenAI hackathon ever held in Poland.

You’ll work in teams of 3–4 on challenges prepared with our case partners, using OpenAI tools and support from mentors on-site throughout the day.

No need to come with a finished team. You can apply solo and we’ll match you with other builders.

What to expect:
⚡ real cases, not made-up exercises
🧠 mentors and builders from the Polish AI scene
💻 OpenAI Codex credits for participants
🏆 prizes for the winning teams
🤝 networking after the final pitches

Bring your laptop and be ready to build.
