This is tomorrow! Control.dev Founder Story:

How do you build an AI company that transforms one of the most important, and often most manual, functions in every business?

Join us at Startup Sauna for Control.dev Founder Story, an evening with Henri Sipilä, co-founder and CEO of Control.dev. Control.dev is building an AI Financial Controller for modern finance teams, automating financial reporting, budgeting, and forecasting by connecting data across ERPs, accounting systems, and payment platforms.

In this founder story, we’ll dive into how Control.dev came together, what it takes to build AI for finance, and what the early journey of a B2B startup really looks like.

Come by, bring your questions, and get inspired. Snacks and refreshments will be served!

Prompt Workshop 6: Build Agents for Studies

Due to high demand we are organizing a second workshop on building agents for studies!

Study season is back. Most people use AI to answer individual questions: one prompt, one response, done. A study agent does something different: it runs the whole workflow. Agents can also act as personal assistants for you along your study journey, managing your calendar, following deadlines, helping you with communications and finding interesting events and opportunities.

Join us for a hands-on workshop on:
• How study agents differ from a single AI prompt
• Vibe coding and agent building basics
• Live build-along: everyone ships a working agent before we close

Skill level: Intermediate; you don't have to be familiar with building agents

• Live build-along: everyone ships a working agent before we close

Skill level: Intermediate. You've used Claude or another AI tool before; you don't have to be familiar with building agents
