F/MS BLOG - Startup News: Key Lessons, Tips, and Mistakes for Building AI Startups in Europe with Insights from J12's Emmet King in 2025 (F/MS Europe, EU-Startups Podcast | Episode 147: Emmet King)

In a European startup ecosystem still grappling with a slow pivot toward AI dominance, the conversation with Emmet King, Founding Partner at J12, struck me as energizing and full of possibilities. J12’s focus on early-stage investments across Stockholm, Paris, and London makes it uniquely positioned to influence how Europe moves forward in building systems that can compete globally in artificial intelligence, and the insights shared are worth dissecting closely.

Let’s start with an often-overlooked aspect, Europe’s constraints. One recurring theme in the startup world is capital scarcity. J12’s own investment thesis pulls a stark contrast here when comparing Europe to regions like the US. Not only does Emmet’s firm look for “highly technical founders” with deep skill sets, but they also aim to back projects designed for long-term durability rather than shallow, hype-driven apps. It’s a smart move, one that acknowledges the limitations startups face when trying to scale technologies that demand hard-to-access resources like compute power and energy.

Now, let’s dig into specifics. J12 seems laser-focused on infrastructure-heavy AI concepts for a good reason. Take compute capacity as an example. Energy-hungry models need access to affordable power, and let’s face it, Europe lags far behind in this area. It's a challenge that, if solved, could be monumental in growing tech ecosystems that don’t default to outsourcing their brightest projects elsewhere.

Another standout is J12’s differentiated approach to talent. Emmet mentioned Europe’s world-class engineering and scientific capabilities, something I’ve seen firsthand in conversations with founders across Dutch hubs like Eindhoven and international accelerators. The tough question is whether the governmental policy will finally act as a driver and not a barrier to unleashing that talent at scale. Visas, energy infrastructure, public-private partnerships for funding smarter solutions, it’s an uphill battle, but Emmet’s take was clear. Teams succeeding in Europe will likely put trust, privacy, and productivity front and center.

Emmet debunked another popular misconception about AI investments, the bubble narrative. Instead of frothy speculative projects, the real action lies in startups investing heavily in defensible systems of value creation, particularly those building on top of existing infrastructure. It reminded me of where blockchain was ten years ago, lots of flashy, short-lived concepts but very few sustainable models. AI in Europe could either repeat that mistake or find a path forward through slow, deliberate growth.

It’s worth reflecting on how to approach building AI startups effectively in Europe. Here are some actionable steps for emerging founders:

A Short Guide for Founders

  1. Focus on Infrastructure: Europe is shifting toward foundational technologies as key drivers. Startups should avoid surface-level concepts like wrapper tools for existing AI and push instead for models requiring durable, defensible infrastructure.
  2. Secure Strategic Resources Early: Beyond funding, founders need access to energy, compute, and data-sharing arrangements. Building relationships with local governments and energy providers might be tricky but critical.
  3. Champion Privacy and Productivity: Use Europe’s unique regulatory approach to data privacy as a competitive advantage. Let it shape trust-driven strategies in enterprise AI.
  4. Build Long-Term Partnerships: Seek VCs like J12 with a thesis-driven investment style that doesn’t shy away from deep tech. Whether a venture firm or angel investor, having those collaborators onboard is more likely to result in relevant funding.

Common Mistakes to Avoid

  • Overestimating Quick Returns: Infrastructure AI takes time to mature; skipping steps for faster deployment often dilutes scalability.
  • Ignoring Regional Challenges: Capital might be tighter in Europe, but ignoring market realities like energy bottlenecks will accelerate failure.
  • Skipping Talent Prioritization: A lightweight startup won’t go far without prioritizing the recruitment and retention of highly technical teams.

The European AI startup scene might be at a crossroads, but collaboration, across VCs, policymakers, and tech entrepreneurs, ushers in hope. I’m convinced that firms like J12 will play a pivotal role in steering the region toward sustainable leadership in AI-driven deep-tech projects. Their investments tell an exciting story, one that challenges Europe’s traditionally conservative tech sector to innovate harder, faster, and smarter.

You can explore more about J12’s investment vision through their official site. And if you're curious about how talent and resources might shape the next wave of startups in cities like London and Paris, listening to Emmet King on EU-Startups Podcast is time well spent.

European startups have plenty of obstacles ahead, but the solutions are already visible if we look at the right examples.
