Navigating Vertical AI Startups 1 — Business Models
Supported by Wave Ventures
For the first event in Prompt's new series, we’re joined by Pirkka Palomäki ( http://Maki.vc/) and Mikko Silventola to unpack what actually makes vertical AI companies work as businesses and where the “AI hype” still doesn’t translate into durable value.
Join us for a fireside chat on:
• What business models make sense for vertical AI (services vs software, usage vs outcome pricing, etc.)
• Where the real moats come from (distribution, workflow ownership, data, regulation, switching costs)
• Why some vertical AI companies will look more like “AI-enabled operators” than SaaS

Prompt Workshop 1 — Building Skills
For the first Prompt Workshop, we’re going super practical: how to go from “chatting with AI” to building reusable workflows you can run anytime. We’ll learn how to create Claude skills / custom commands and turn them into a personal toolkit — without needing prior AI tooling experience.
Join us for a hands-on workshop on:
• How Claude skills/custom commands work
• Turning a one-off prompt into a reusable workflow you can trust
• A live build-along: everyone builds one skill end-to-end
• A challenge round: build your own skill with support + feedback
• Demos + next steps
Skill level: Beginner

We're looking for technical people, who want to build cool shit, but don't yet know what real problem they can solve. In this sprint we'll give you space, guidance and structure to find this problem.
- 2 weeks
- for technical people to find out what they want to build
- come without an idea, solo or with a team
Worst case: you learn how to do market research and outreach, and you've tried your best.
Best case: you build a working solution to a real problem and already have a paying pilot customer.
(you can do this alongside your courses and exams)
Apply by May 17th. Sprint runs May 18 - June 1.

Pitching in front of people can feel like a big thing.
That’s why Pitch It works.
The room feels human, but real enough to count.
You can try your idea out loud without huge pressure.
It’s a safe place to do something a little brave.
Come by and see for yourself.

From our friends at Founder School:
Founder Talks #7: Ilkka Paananen, Founder & CEO of Supercell
From Clash of Clans to Brawl Stars, Ilkka Paananen built one of Europe’s most iconic tech companies - and the first to hit a $10B valuation - by doing things differently: smaller teams, long-term thinking, and an obsession with culture.
In Founder Talks #7, Ilkka opens up the playbook behind Supercell, the lessons from building global hits, and how he now supports the next generation of founders through Illusian and beyond.

A room, a mic, a few short pitches.
Some come to pitch. Most come to watch.
It’s not formal, and it’s not just for startup people.
You’ll hear prepared ideas, rough ones, and sometimes something completely playful.
After the pitches, people stick around. That’s when the conversations start.
Stop by if you feel like it.

Will startups be built the same way in 2 years?
For Agentic Age 3, we’re joined by Juho Eräste from https://taito.ai/?utm_source=luma to go deep on what it actually means to build an AI-native startup. Not “AI features”, but an AI-first operating system for how a company runs.
https://taito.ai/?utm_source=luma is a Slack-native performance enablement platform that automates expectations, continuous feedback, coaching, and reviews with an always-on AI agent, helping teams grow with less management overhead.
Join us for a fireside chat on:
• What you design “agent-first” from day 1 (product, org, internal tooling)
• Where humans still have to stay in the loop (especially in people decisions)
• What the real moats are when building software gets dramatically easier
