Iron Gate: How the small Swedish studio created Valheim
Iron Gate is remarkably small for the developer responsible for one of modern survival gaming’s biggest success stories.
The Swedish studio created Valheim, the Viking survival game that exploded on Steam in 2021 before growing into a global hit with more than 12 million copies sold. Yet the company behind that success has resisted becoming an enormous development operation.
Iron Gate’s current Valheim FAQ lists just 19 people, and not all of them work directly on game production. The studio also says it wants to remain small and independent.
That makes Valheim’s scale unusual.
What began as Richard Svensson’s solo project eventually became a game played by hundreds of thousands of people simultaneously. It spent more than five years growing through Early Access before reaching version 1.0 in September 2026.
Behind that enormous Viking world remains a deliberately small Swedish developer.
Iron Gate began with two Swedish developers
Iron Gate was founded by Richard Svensson and Henrik Törnqvist.
Both already had experience in game development. The studio’s official company history says they previously worked on games including Magicka 2 and titles in the Titan Quest series.
However, Iron Gate’s story really begins before the company itself.
It begins with Valheim.
Valheim started as a solo project
Before millions of people explored Valheim, Richard Svensson was building it alone.
The official Valheim FAQ says the game had already spent approximately two years in development as a solo project before the company was established.
That origin helps explain much about the developer that eventually formed around it.
Valheim did not begin as an enormous project with hundreds of developers, multiple production teams and a giant publisher.
It began with one developer building a Viking survival game.
A studio gradually grew around that project.
Iron Gate’s founding year needs some explanation
There is a small complication when documenting Iron Gate accurately.
The company’s official About page says the studio was founded in 2018 by Richard Svensson and Henrik Törnqvist.
However, the official Valheim FAQ says the company was founded in 2019, after Valheim had already spent two years as Svensson’s solo project.
TechnologyBlog therefore does not treat either date as indisputable.
The safest interpretation is that Iron Gate traces its beginnings to 2018, while its Valheim FAQ places the formal company formation in 2019.
What is much clearer is how small the operation remained.
Iron Gate initially had only three people
According to the official Valheim FAQ, the company consisted of its two co-founders and one employee when it was established.
Two more people joined during the following year. Another two arrived shortly after Valheim entered Early Access.
That means one of PC gaming’s biggest stories of 2021 came from a development team small enough to fit comfortably around a single table.
Valheim’s audience subsequently grew at extraordinary speed.
Iron Gate chose not to grow at the same rate.
Skövde became the studio’s home
Iron Gate is based in Skövde, Sweden.
The studio describes its home as being close to the Nordic forests that helped inspire Valheim’s world.
That location fits the game remarkably well.
Valheim does not attempt to recreate historical Scandinavia exactly. Instead, it creates a mythological Viking afterlife filled with forests, mountains, oceans, monsters and abandoned settlements.
Its Scandinavian identity remains fundamental to the experience.

Valheim combines survival with Norse mythology
Valheim places dead Viking warriors inside a mysterious tenth realm.
Odin has sent the player there to defeat creatures he banished.
That provides the narrative foundation for an open-world survival game where players gather resources, build, craft, hunt, sail, explore and fight.
Eventually, they challenge increasingly dangerous bosses and environments.
The individual mechanics were not entirely new.
Iron Gate’s combination of them was what made Valheim distinctive.
Iron Gate made survival less exhausting
Many survival games constantly punish players for failing to maintain basic needs.
Iron Gate took a different approach.
Food does not simply prevent the player from starving. Instead, different foods determine health and stamina.
Better meals therefore improve what players can accomplish.
A difficult expedition begins with preparation rather than constantly feeding a hunger meter simply to stay alive.
That difference changes Valheim’s rhythm considerably.
Preparation matters without ordinary survival becoming endless maintenance.
Building became one of Valheim’s defining systems
Construction also became enormously important.
Players begin with basic shelters.
Eventually, they can build longhouses, ports, villages, fortifications and enormous settlements.
However, construction is not purely decorative.
Foundations matter.
Structural support matters.
Smoke needs somewhere to escape.
Different materials create different possibilities.
As a result, building becomes part creativity and part engineering.
That system helped create a huge community of players who spend as much time constructing as fighting.

Procedural worlds make every journey different
Valheim’s world is procedurally generated.
Players therefore do not all receive exactly the same map.
Biomes follow underlying rules, but coastlines, islands, resources and locations change between worlds.
Consequently, one player’s journey cannot simply become another player’s route.
People can share knowledge about how Valheim works.
They cannot completely share the experience of discovering a particular world.
That gives exploration a personal quality.
Sailing changes the scale of Valheim
Eventually, Vikings need boats.
That transforms the experience.
A coastline stops being the edge of the known world and becomes the beginning of another journey.
Players sail across procedurally generated oceans looking for new land.
Sometimes they find the biome they need.
Sometimes they discover valuable resources.
Sometimes the weather becomes the problem.
Occasionally, something in the ocean decides the expedition should end differently.
That uncertainty turns travel into gameplay rather than a loading screen between destinations.
Valheim exploded after its Early Access launch
Valheim entered Steam Early Access on 2 February 2021.
The response was extraordinary.
What could have remained a comparatively small survival project became an international phenomenon.
Millions of copies sold.
Steam concurrency soared.
Communities formed.
Players began constructing extraordinary settlements.
Suddenly, Iron Gate was responsible for one of PC gaming’s biggest survival games.
Yet the studio behind it remained tiny.
Success created a different problem for Iron Gate
Selling millions of copies sounds like the best possible problem for a small developer.
It also creates expectations.
Players wanted more biomes, enemies, equipment, building pieces, optimisation and fixes.
Iron Gate could have responded by hiring an enormous development team.
Instead, the company expanded cautiously.
That decision became central to Valheim’s development.
Iron Gate wants to remain small
The studio is unusually clear about this.
Its current FAQ says Iron Gate intends to remain a small and independent company.
That explains why Valheim’s success did not suddenly transform the developer into a 200-person organisation.
Iron Gate added people, but growth remained controlled.
The current FAQ lists 19 people and specifically notes that not everyone works directly on game production.
That remains tiny compared with many developers responsible for games reaching a similar global audience.
Coffee Stain became an important partner
Iron Gate did not have to handle every part of Valheim alone.
Coffee Stain Publishing became its publishing partner.
The relationship also extends beyond a conventional publishing agreement.
Coffee Stain’s corporate history says it acquired a 30% minority stake in Iron Gate in 2019.
That distinction matters.
Coffee Stain has a financial interest in the studio, but Iron Gate continues describing itself as small and independent.
The relationship gives the developer access to publishing support without requiring it to build every business function internally.
Publishing support helps Iron Gate remain small
Iron Gate’s FAQ says Coffee Stain Publishing assists with marketing and other business responsibilities.
The studio also works with external freelancers and partners for selected development tasks.
That helps explain how a 19-person company can support a game with millions of players across several platforms.
The internal team does not personally perform every task surrounding Valheim.
Instead, Iron Gate retains a small core while working with external specialists where necessary.
Valheim grew biome by biome
Early Access gave Iron Gate years to expand its Viking world.
Progression revolves around increasingly dangerous biomes.
The Meadows provide the beginning.
The Black Forest introduces new resources and threats.
The Swamp punishes poor preparation.
Mountains introduce environmental danger.
The Plains increase combat pressure.
Mistlands dramatically changes visibility while expanding late-game progression.
Ashlands transforms the environment into another hostile battlefield.
Eventually, one major biome remained.
The Deep North.
Each biome required more than new scenery
Adding another Valheim biome is not simply a matter of changing the landscape.
A biome needs resources.
Enemies.
Equipment.
Food.
Locations.
Progression.
Building materials.
Environmental characteristics.
Those systems must also interact with everything already present in the game.
Therefore, each major expansion added another interconnected layer to Valheim.
That helps explain why the Early Access journey lasted so long.
Iron Gate resisted rushing Valheim to version 1.0
Valheim’s enormous 2021 success could have encouraged the developer to remove the Early Access label quickly.
Iron Gate did not.
Instead, development continued for more than five years.
That occasionally frustrated players waiting for major updates.
However, the studio continued building towards the progression it had promised.
Then, in 2026, the destination finally came into view.
The Deep North completed Valheim’s biome progression
The Deep North was the last major missing piece.
Frozen landscapes brought new enemies, locations, resources and progression.
Version 1.0 added more than 40 weapons, four armour sets, more than ten creatures and over 80 building pieces alongside the completed biome.
For long-term players, however, the Deep North represented something bigger than another content update.
It completed the journey.

Iron Gate finally released Valheim 1.0
On 9 September 2026, Iron Gate and Coffee Stain Publishing officially released Valheim 1.0.
The Early Access label disappeared.
The Deep North opened.
The planned biome progression was finally complete.
This is also where the article should contain its primary TechnologyBlog internal link.
Internal link anchor: Valheim 1.0
Link that phrase to the published TechnologyBlog article:
Valheim 1.0 brings hundreds of thousands of players back for the Deep North
That article covers the full 1.0 update, Steam resurgence, Deep North content and current player activity in detail.
Valheim 1.0 is much larger than the 2021 game
The finished version contains more than five years of accumulated development.
Mistlands exists.
Ashlands exists.
The Deep North is complete.
Achievements have arrived.
Additional platforms joined the ecosystem.
Crossplay expanded.
New equipment, creatures, food, crafting systems and construction pieces transformed progression.
Yet the core experience remains recognisable.
Explore.
Prepare.
Build.
Sail.
Fight.
Then go further.
Iron Gate expanded Valheim across more platforms
The 1.0 launch also expanded Valheim’s reach.
PlayStation 5 and Nintendo Switch 2 joined its existing platform ecosystem, while crossplay connects supported platforms.
That represents a substantial technical challenge for a studio as small as Iron Gate.
External partners have helped with some platform work, demonstrating again why the company’s 19-person internal headcount should not be mistaken for the total number of people contributing to Valheim.
Iron Gate has sold more than 12 million copies of Valheim
The commercial scale remains extraordinary.
Iron Gate says Valheim has sold more than 12 million copies worldwide.
That gives the studio’s size important context.
Its core company remains smaller than many individual development departments at major publishers.
Yet its first game reached an audience measured in millions.
Valheim transformed Iron Gate from a largely unknown Swedish studio into a developer recognised around the world.
Valheim remains Iron Gate’s defining game
Iron Gate’s official website remains overwhelmingly centred on Valheim.
There is no enormous back catalogue.
There is no annual release schedule.
There are not half a dozen established franchises.
The developer’s identity remains closely connected to one game.
So far, one game has been enough.
One game occupied years of development
Remember where Valheim began.
Richard Svensson worked on it alone before the studio formed around the project.
The game then spent years in development before Early Access.
Another five and a half years passed before version 1.0.
Valheim therefore represents a substantial portion of Iron Gate’s history.
The studio did not respond to its surprise success by immediately abandoning the project for a sequel.
It stayed with Valheim and completed it.
The community became part of Valheim’s identity
Valheim’s players did more than progress through its bosses.
They built.
Some creations became enormous.
Players constructed castles, villages, ports, bridges, temples and sprawling settlements.
Iron Gate regularly highlights community creations through its official communication.
That reinforces one of Valheim’s strongest qualities.
The developer provides systems.
Players decide what those systems become.
Some want to defeat every boss.
Others spend hundreds of hours constructing.
Both approaches belong in Valheim.
Iron Gate communicates like a small studio
The developer’s communication also reflects its size.
Updates often come directly from the team.
Community creations receive attention.
Development teasers appear alongside broader studio news.
That creates a different relationship from communication managed entirely through a large publisher’s corporate structure.
Valheim may have millions of players.
The company making it remains comparatively compact.
Being small has disadvantages too
There is an obvious trade-off.
Small teams cannot produce content at the speed of enormous development organisations.
Major Valheim updates sometimes required long waits.
Players occasionally became frustrated.
The Deep North itself took years to reach completion.
Iron Gate’s decision to remain small therefore has consequences.
However, it also helps explain why Valheim has retained such a consistent identity.
The game never became an annual content machine.
Iron Gate did not turn Valheim into a seasonal treadmill
Valheim receives updates, but its structure remains different from a conventional seasonal live-service game.
Players are not required to return every week because temporary content is about to disappear.
They can leave their world.
Months can pass.
Then they can return.
That flexibility suits a survival game where a player’s own world and creations form much of the experience.
Valheim 1.0 does not mean development has ended
Version 1.0 completed the planned biome progression.
It did not mean Iron Gate immediately stopped working on Valheim.
Post-launch fixes began quickly, addressing technical issues and problems associated with the major release.
However, Iron Gate has been careful about promising another huge content expansion.
The studio has not committed to another major biome.
That restraint is sensible.
Iron Gate spent years explaining what needed to exist before Valheim could reach 1.0.
It has now delivered that journey.
Iron Gate has not announced another major game
As of late September 2026, Iron Gate has not publicly announced another major game that TechnologyBlog can responsibly describe as its next project.
Speculation is therefore unnecessary.
The developer may continue expanding Valheim.
It may eventually create something completely different.
Both could happen.
Until Iron Gate announces its plans, the responsible position is simple.
We do not know yet.
Remaining small could define Iron Gate’s future
What the company has stated clearly is arguably more interesting.
Iron Gate wants to remain small and independent.
That philosophy could determine its future more than any particular franchise.
Valheim proved the studio does not require hundreds of permanent employees to reach an enormous global audience.
Coffee Stain’s publishing support and minority investment provide additional resources without requiring Iron Gate to become a massive organisation itself.
That model has already produced an extraordinary result.
Iron Gate is part of Sweden’s wider game-development story
Iron Gate also demonstrates the strength of Sweden’s development ecosystem.
A small team in Skövde created a game capable of reaching millions of players globally.
Coffee Stain, another company with roots in Skövde, became its publishing partner.
External development companies helped bring Valheim to additional platforms.
The result demonstrates that globally successful games do not need to emerge exclusively from the world’s largest development centres.
A small Swedish studio can build something enormous.
Iron Gate and Valheim for South African players
For South African players, Valheim’s structure offers useful flexibility.
The game supports solo play.
Groups can organise cooperative sessions.
Dedicated servers provide another option.
Crossplay connects supported platforms.
Therefore, players are not dependent on a large South African public matchmaking population to experience the game.
Network quality will still depend on server location, host location and routing.
There is no responsible universal South African latency figure for Valheim.
However, having control over where and how a group plays can be valuable.
Why Iron Gate’s story matters
The remarkable part of Iron Gate is not simply that Valheim became successful.
Independent games become successful every year.
What makes this story unusual is the difference between the scale of the studio and the scale of its audience.
Iron Gate’s current FAQ lists 19 people.
Valheim has sold more than 12 million copies.
Its 2021 Early Access launch became one of Steam’s biggest survival-game phenomena.
More than five years later, the same small studio finally delivered version 1.0.
That is an unusual development story.
Iron Gate remains a small studio behind a very big game
Iron Gate is a small Swedish developer based in Skövde.
Its story began with Richard Svensson building Valheim as a solo project.
Henrik Törnqvist joined him.
A company formed.
Coffee Stain became its publishing partner and minority investor.
Then Valheim changed everything.
Millions of copies sold.
Hundreds of thousands of people played simultaneously.
New biomes expanded the world.
Additional platforms joined.
Yet Iron Gate resisted becoming an enormous studio.
In September 2026, Valheim finally reached the destination the team had spent years working towards.
The Deep North opened.
Early Access ended.
Version 1.0 arrived.
For many developers, that would already represent an extraordinary company history.
For Iron Gate, it is the story of its first major game.
Whatever comes next, the studio has already demonstrated something important.
A small team can build a very big world.
