Space, a San Francisco startup building a filesystem that makes cloud files behave like local ones, has raised $2.4 million in pre-seed funding led by a16z Speedrun. Golden Ventures, Northside Ventures and around a dozen angel investors with backgrounds at prosumer and enterprise software companies including Parsec, Sentry, Stan, Superwhisper and Modem also joined the round.

Space shows up on a computer as an ordinary drive. Files sitting in the cloud appear in Finder and open in the applications people already use, but nothing is downloaded first. When an application asks for data, Space streams only the exact byte ranges it needs, in real time, and keeps a local cache of just the parts that were touched. The company says this lets a laptop open and edit terabytes of files while using no disk space of its own.

## Why Cloud Storage Still Fills the Disk

Cloud storage was sold as a way to make computers feel limitless. In practice, the major services still revolve around copying whole files onto the device. Dropbox, Google Drive and Microsoft OneDrive all offer files on demand, showing lightweight placeholders until a file is opened, but opening one triggers a download of the entire file. For a 40-gigabyte video project on a laptop with 20 gigabytes free, the placeholder does not help.

Streaming file access does exist at the professional end of the market. LucidLink, which raised $75 million in 2023 from investors including Adobe Ventures, streams file data on demand for film and post-production teams, and Suite Studios has raised around $20 million for a similar service aimed at editors. Space is going after the same mechanics with a broader claim: that streaming should be the default way every computer, and every AI agent, reaches every file.

## A Virtual File System That Streams Instead of Syncing

Space is built directly above the operating system as a virtual file system, low enough that applications do not know the difference between its files and local ones. The company says Premiere, DaVinci Resolve, Photoshop and Blender work unmodified, with no plugins. A video editor can scrub through a project larger than their machine's entire drive, an architect can open a building model whose assets stream in as the software requests them, and a developer can work across a repository without storing it on a laptop.

> "The computer no longer needs to hold every file. It becomes a window into any file, wherever it lives and however large it is."
> — Matthew Ao, co-founder of Space

Because every device streams from the same live filesystem, the company says teammates can open a file before a colleague's upload has even finished, with version history and search across the whole store built in.

## File Access for AI Agents

Before an AI agent can work on a company's data, that data usually has to be copied, ingested into a separate tool or indexed into a retrieval pipeline. Most agentic tools ask users to upload an entire file to a chatbot even when the task needs one page of a document or one frame of a video. Developers have built whole categories of connectors, including the widely used filesystem servers in the Model Context Protocol ecosystem, precisely because agents need file access without a custom integration for every application.

Space's answer is to give agents the same primitive it gives people: a filesystem they can navigate directly, reading only the byte ranges relevant to the task. An agent could traverse an organization's full set of files through the drive itself, with no ingestion step, which is the kind of plumbing agentic workflows currently lack.

"Humans and agents are working across more data than any local disk can hold. They should not have to wait for files to be copied or ingested before work can begin," said Jason Zhao, co-founder of Space.

## From Vlog Footage to a Filesystem

The founders ran into the problem they are now selling a fix for. Matthew Ao and Arihant Bapna previously built Kortex, a note-taking app created with the writer Dan Koe, and later rebuilt it as Eden, an AI workspace for creatives. Jason Zhao has spent a decade documenting his life on YouTube and says he accumulated dozens of terabytes of footage across external drives along the way. At their previous company, the founders say, the team moved terabytes of footage every month, losing hours to uploads and downloads and losing whole workflows when someone left a drive at home.

They built the first Space prototype in November 2025 and developed the product while working out of Founders Inc., an accelerator campus at Fort Mason in San Francisco. The company says demand during the raise grew faster than the team could keep up with. Space is currently in private beta with roughly 100 users and teams onboarded.

## Inside the a16z Speedrun Round

Speedrun is the accelerator Andreessen Horowitz launched in 2023 under general partner Andrew Chen. It began with games and has widened into AI and consumer software, running twelve-week cohorts in San Francisco with reported acceptance rates below 1 percent. Its standard 2026 terms are an investment of up to $1 million plus around $5 million in credits, which makes Space's $2.4 million round, led by the program, larger than the usual Speedrun cheque.

Golden Ventures and Northside Ventures, the two named funds alongside Speedrun, are both Toronto seed investors. Northside writes first cheques into Canadian founders anywhere in North America, which fits a founding team with roots in the Toronto tech scene.

"Space is disrupting one of the oldest assumptions in computing: a file has to exist on your device before you work with it," said Jonathan Lai, general partner at a16z. "Matt, Ari and Jason are innovating with a new type of AI-native filesystem that can serve both human creators and AI agents with the same primitive: instant access to the exact data they need."

## What Comes Next

Space is starting with teams whose work already exceeds a local disk: video production, marketing, and architecture, engineering and construction firms, industries that are also early adopters of agentic workflows over large sets of unstructured files. From there the company plans to move into AI training data infrastructure, media and entertainment, computer vision and enterprise data systems. The founders call the long-term goal the Space Computer: a machine that acts as a window into effectively unlimited storage and compute rather than a box that has to contain them.

## FAQ

**Q: How is Space different from Dropbox or Google Drive?**
Those services keep synced copies of whole files on the device, and their on-demand modes still download the full file the moment it is opened. Space never stores a full copy locally. Applications read just the byte ranges they need over the network, so a project bigger than the laptop's drive is no longer a problem.

**Q: How is Space different from LucidLink?**
LucidLink streams file data on demand too, but it is sold to film and post-production teams as workflow infrastructure. Space is pitching the same mechanics as an everyday filesystem for anyone with a full disk, and treats AI agents as users of the same drive rather than something bolted on through integrations.

**Q: Does Space work offline?**
Partly. It keeps a local cache of the parts of files already touched, so recently used material stays available, but the product is built around live streaming from the cloud rather than offline copies. Anyone regularly editing on planes will want to test that trade-off during the beta.

**Q: How do you get access to Space?**
As of writing, Space is in private beta, with roughly 100 users and teams onboarded so far. The company is prioritizing the industries named in its expansion plan, video, marketing and AEC firms, and takes demo bookings through its site.
