Plakar raises $3M from Seedcamp to Launch AI-Ready Open Source Backup Platform

Plakar, an open-source backup and restore platform, today announced the general availability of its first stable release, alongside a $3 million pre-seed funding round led by Seedcamp. The round includes participation from leading venture firms HelloWorld, IrregularExpression, Galion.exe, Kima Ventures, OPRTRS and renowned angel investors, including Olivier Pomel (Datadog), Solomon Hykes (Docker), and Alexandre Yazdi (Voodoo).

Plakar’s modern architecture enables users to protect and orchestrate various types of data across a diverse set of environments in a way that is fast, reliable, and resource-efficient. Plakar doesn’t just store files—it preserves complete application and AI-pipeline context. It deduplicates and compresses data inline, encrypts it end-to-end, and organizes it into a structured, queryable repository.

Unlike traditional backup solutions, where data becomes a dormant cost, Plakar transforms backup storage into an active, valuable resource. Its architecture enables seamless reuse of protected data for production workflows, such as AI model training, data analytics, compliance auditing, or offloading intensive tasks from production systems, unlocking new operational efficiencies and accelerating innovation.

“With Plakar, we’re providing an open-source solution that simplifies backup and restore processes while making enterprise-grade data resilience accessible to businesses of all sizes,” said Julien Mangeard, co-founder and CEO of Plakar. “This product launch and funding announcement is a significant milestone, and we are thrilled to begin this journey with the support of such renowned partners and investors.”

“In an era where AI systems are generating and processing unprecedented volumes of data, ensuring the integrity and security of that data is paramount,” said Sia Houchangnia, Partner at Seedcamp. “Plakar’s approach of combining open-source flexibility with enterprise-grade features aligns with our belief in empowering developers and businesses with accessible, reliable, and efficient tools.”

Plakar’s engine, called Kloset, turns each backup into a compact, self-contained, immutable data unit that travels with its own structure, metadata, and encryption. Like a container for data, it removes the need for external coordination or dependencies—enabling fast, secure, and portable backups across any environment, from local files to distributed cloud systems.

Plakar’s end-to-end workflow keeps every backup lean, secure, and instantly recoverable with the following features:

• Data Collection: Immutable, content-addressed snapshots capture incremental versions of datasets and model checkpoints so experiments remain fully reproducible while slashing redundant storage by up to 90%.
• Data Visualization: Snapshots are browsable and verifiable without restoring, and restores are precise and fast.
• Data Security: Plakar uses the same end-to-end encryption to ensure compliance with stringent data-protection regulations.
• Resource Efficiency: By combining advanced deduplication and compression techniques, Plakar minimizes storage requirements, allowing for more restore points with less space.
• Interoperability: Plakar integrates seamlessly with various storage environments, including cloud-based storage, S3-compatible solutions, local servers, NAS, SAN, tape drives, and Kubernetes volumes.

With the new funding, Plakar plans to expand its engineering team to accelerate feature development and enhance platform scalability. Additionally, the company aims to grow its customer base by targeting AI-focused startups and enterprises seeking efficient, secure, and reproducible data management solutions.
