Every mentor, investor, and startup advisor will tell you the same thing: focus. Pick one thing. Do it well. Say no to everything else.
This is excellent advice for most people in most situations. It is wrong for me, and I want to explain why - not to be contrarian, but because I think the "focus on one thing" dogma obscures a more interesting strategy that more founders should consider.
I currently run or co-build five things:
- Vantar Energy - Bringing thorium molten salt reactor technology from China to Europe
- Zero Slide - AI consulting and implementation for businesses
- Vantar AI - Open-source SDK and cloud for neuromorphic computing
- Oslo Project - Coordination framework for civilization-scale challenges
- Heliogenesis - Tools and methodology for solar-aligned community building
On the surface, this looks unfocused. A nuclear energy company, an AI agency, a neuromorphic computing platform, and two civilization-design projects. What do these have in common?
The shared thesis
Everything I build is rooted in a single observation: the infrastructure that civilization runs on - energy, computation, coordination - is inadequate for what is coming.
Energy: Europe burns gas it cannot afford, from countries it cannot trust, producing emissions it cannot sustain. The energy infrastructure needs a generation-level upgrade. That is Vantar Energy.
Computation: GPUs consume absurd amounts of energy to run AI workloads. Neuromorphic chips can do similar work at 1,000x less power. But nobody can use them because the software doesn't exist. That is Vantar AI.
AI deployment: Most businesses know they need AI but cannot figure out where to start, what to build, or how to make it stick. That is Zero Slide.
Coordination: The biggest challenges - climate, energy transition, institutional reform - require coordination between entities that have no natural mechanism for working together. That is the Oslo Project.
These are not random interests. They are different expressions of the same conviction: civilization's infrastructure needs to be rebuilt, and the people who build it will define the next century.
Why multi-company founders exist
The "focus" advice assumes that companies are isolated entities competing for a founder's finite attention. But some companies are better understood as nodes in a network - they share knowledge, relationships, and strategic insight in ways that make each one stronger.
Elon Musk runs Tesla, SpaceX, Neuralink, The Boring Company, and xAI. The standard critique is that he is spread too thin. The reality is that SpaceX's manufacturing innovations inform Tesla's production. Tesla's battery technology informs SpaceX's energy storage. Neuralink's neural interface work informs xAI's understanding of intelligence. Each company makes the others better.
This is not unique to Musk. Richard Branson built 400+ companies under the Virgin brand. Jack Dorsey ran Twitter and Square simultaneously. Manoj Bhargava runs dozens of companies across energy, water, and health.
The pattern is always the same: a founder with a thesis that spans multiple markets, building companies that share a strategic backbone while operating independently.
The practical advantages
Cross-pollination of networks. My Vantar Energy investor conversations introduce me to energy policy people who become relevant for the Oslo Project. My Zero Slide AI clients have industrial operations that could become Vantar Energy customers. My neuromorphic computing work connects me to researchers who inform everything else. Every conversation in one company creates optionality in another.
Diversified risk. If thorium MSR regulation takes longer than expected, Zero Slide generates revenue. If AI consulting has a slow quarter, neuromorphic computing research continues. No single failure is existential. This is not hedging - it is building a portfolio of ventures with different timelines and risk profiles that collectively are more resilient than any one alone.
Compounding reputation. A founder who works on nuclear energy, AI, and neuromorphic computing is not a dilettante - they are someone who operates at the intersection of deep tech and systems thinking. Each venture adds credibility to the others. An investor evaluating Vantar Energy sees someone who also builds AI systems and understands advanced computing. That is more compelling than a single-company founder with one bet.
Faster learning. Running multiple ventures means encountering a wider range of problems, markets, and people. The pattern recognition that comes from operating across energy, AI, and coordination is richer than what you get from optimizing a single SaaS product for five years.
The honest downsides
I am not going to pretend this is easy or without cost.
Context switching is real. Going from a thorium fuel cycle conversation to an AI automation deployment in the same afternoon requires discipline. Some days the switching cost is high.
Depth vs. breadth. A founder who spends 100% of their time on one company will know that company better than I know any one of mine. This is a real tradeoff. I mitigate it by hiring well and building systems, but the tradeoff exists.
Fundraising is harder. Investors want founders who are "all in" on one thing. Explaining a multi-company thesis requires more sophisticated investors who understand portfolio thinking. Not all of them do.
Execution risk. More companies means more surfaces for things to go wrong. A crisis in one company can consume attention needed by others.
These are real costs. I pay them knowingly because the strategic upside outweighs them - for my specific situation, with my specific thesis.
When to do this (and when not to)
Multi-company building works when:
- Your thesis genuinely spans multiple markets
- The companies create synergies that would not exist independently
- You have the operational systems to manage complexity
- Each company can function without you in the room every day
- You have high tolerance for context switching
It does not work when:
- You are starting your first company and still learning the basics
- The companies are unrelated and share nothing
- You are using "multiple companies" as an excuse to avoid the hard work of making one succeed
- You cannot delegate effectively
I spent years building individual products before attempting this. Zero Slide generates real revenue. The other ventures are funded or self-sustaining. I am not running five companies on hope - I am running them on a thesis that has been tested in at least one market.
The meta-point
The "focus on one thing" advice comes from a world that assumes founders are building products. But some founders are building systems - and systems, by definition, span multiple domains.
If your ambition fits in a single company, by all means focus. Build the best version of that one thing. That is a great path.
But if your ambition is infrastructure-level - if you are trying to rebuild how civilization generates energy, computes, and coordinates - then one company is not enough. One company is a tool. You need a toolbox.
I am building a toolbox. Each tool serves a different purpose. Together, they build something none of them could build alone.
