Investment firm & studio — Stockholm, since 2025.
We invest our own capital, and build the companies we'd rather own outright.
Nashsphere is a four-person firm in Stockholm. We back founders with angel and early-stage cheques, take positions in public companies and IPOs, and develop our own products — wherever our edge is clearest.
How we invest
Four ways we put capital to work.
Different shots on goal — angel bets, private rounds, public positions, and the products we build — chosen so the wins don't all rise and fall together.
- 01
Angel investing.
First cheques into founders we'd happily work for. Small, early, and hands-on when it helps — out of the way when it doesn't.
- 02
Early-stage private rounds.
Seed to Series A, usually alongside people we've known for years. A real cheque, and a line on the cap table we mean to keep.
- 03
Public companies & IPOs.
We hold listed positions and step into IPOs when the price and the business finally agree. Patience is most of the strategy.
- 04
In-house product development.
Some bets are easier to simply own. When that's true, the four of us build the company ourselves rather than write a cheque.
Where we look
Three industries, for now.
We stay close to what we understand. The list grows slowly, and only when one of us has actually lived the problem.
Tech, AI, robotics & security.
Frontier technology
Where software starts touching the physical world — automation, intelligent systems, and the security that has to travel with them.
Fintech.
Financial infrastructure
The plumbing of money: payments, lending, and the unglamorous rails that quietly compound over a decade.
Real estate.
Property & yield
Bricks and yield — a ballast of harder assets to steady the book against the volatility everywhere else.
The partners
Four founders. One book.
We've worked together long enough to disagree well, which turns out to be most of the job when you're investing your own money.
- A
Andre
Product & design
Draws the thing before we argue about it, then keeps our in-house products honest once they ship.
- J
Johan
Engineering & in-house builds
Owns the stack behind what we build ourselves, and the boring reliability work nobody posts about.
- M
Mikael
Public markets & finance
Watches the listed book and the firm's own ledger — incorporation, capital, and the spine of the thing.
- M
Marcus
Private deals & partnerships
Sources the angel and early-stage rounds, and brings back the awkward truths founders tell him.
