KineDB raises €850K pre-seed for a database that works offline
Copenhagen's KineDB has raised €850,000 pre-seed led by Superhero Capital for one database engine that runs on offline devices and cloud servers, starting with underground mining.

KineDB, a Copenhagen database startup, has raised €850,000 in pre-seed funding led by Superhero Capital to build one database engine that runs on offline devices and on cloud servers.
More applications are being built with AI tools, and Tech.eu points out that this raises the demand on the infrastructure underneath them. KineDB is building for that layer, and it starts in the places where the network disappears. Below, I lay out the round, the product, the market it sells into and what this check signals about early money for European infrastructure.

€850K led by Superhero Capital, with three operator angels
KineDB announced the €850,000 pre-seed round on 29 October 2026. Superhero Capital led it. NGL Ventures joined, along with three business angels: Jussi Pyörre, CTO of Cactos, and Kristoffer Abell and Jakob Lilholm, co-CEOs of the Danish compliance company Formalize.
Today’s Startup News places the company’s headquarters in Copenhagen, and Vestbee describes it as Danish. The founders are Axel Löwenhoff and Allan Zimmermann. The announcement does not give a founding year or team size.
The money has two jobs. KineDB will keep developing its database technology and grow the team, hiring engineers who specialize in databases, storage systems and query engines.
One database for the mine shaft and the cloud
KineDB builds a general-purpose database engine. It runs inside applications on local and offline devices, and on cloud backend infrastructure. Teams that need data both online and offline would otherwise combine separate systems for each case. KineDB puts both in one engine, and data collected offline syncs to a central database once the connection returns.
Löwenhoff put the goal plainly. “With KineDB, we want to remove that as a layer of complication for engineers,” he said.
The company’s site banner, as reported by Today’s Startup News, says it is no sync layer, and adds: “Your servers are optional.” That is a confident line for a pre-seed company. It is also a testable one.
The first target is work in places with unreliable connectivity, and the example the company gives is underground mining. There are few harder tests for an offline database than a mine. The good news for a company this early is that a narrow first market gives it a clear pass or fail. KineDB plans to widen to other types of applications after that.
Database software: $132 billion in 2025, $406 billion by 2034
KineDB sells into database management systems. Fortune Business Insights sized that market at $132.09 billion in 2025 and forecasts $406.03 billion by 2034, a CAGR of 13.29 percent over 2026-2034 (page last updated 12 October 2026). The same source puts Europe at roughly a quarter of the market.
On those figures the market roughly triples over the forecast period. That leaves room for a newcomer to start in one corner, offline and underground, and grow out of it.
Against that backdrop, €850,000 is a small first check. In October on Sesamers, Klarent raised a €7.13 million seed to test AI-written code (11 October 2026), and OllyGarden raised a $4 million seed for telemetry quality (12 October 2026). Both rounds are several times the size of KineDB’s, and both sit at seed, one stage later.
Three October rounds below the application layer
So who looks after the parts of software that new builders no longer have to think about? Löwenhoff is openly positive about the shift. “The way AI has opened the gates for developers of all levels to experiment and launch new software is a wonderful thing,” he said. He also pointed to “a lot of software where creators haven’t necessarily considered the underlying databases”.
That second line is the commercial case. In October I kept seeing the same shape in the rounds we log at Sesamers. Klarent is testing code that AI wrote. OllyGarden works on the quality of telemetry. KineDB is going after the database. Three companies, three layers, each one under the application the end user touches.
The investor list adds an operator angle. Pyörre runs technology at Cactos as CTO. Abell and Lilholm are co-CEOs of Formalize. Operators with day jobs at Cactos and Formalize are writing checks into a database engine at pre-seed, next to Superhero Capital and NGL Ventures.
If AI-built apps end up shipping on a database that already handles the offline case by default, developers of all levels would stop meeting the sync problem the first time a user loses signal. That is the bet this round makes.
Underground first, then other applications
Round size is the wrong yardstick for a company at this stage. The yardsticks worth tracking are simpler: whether a mining crew keeps its data when the signal drops, how fast KineDB fills those database, storage and query engine roles, and when the first application outside mining runs on it. Copenhagen has a new infrastructure company to follow, and its next release will show whether the banner holds.
