A shared context layer that captures decisions, intent, and history to keep humans and AI agents aligned

SEATTLE, May 06, 2026–(BUSINESS WIRE)–SageOx, a startup building shared context infrastructure for AI-native teams, today announced a $15 million seed round led by Canaan Partners, with participation from A.Capital, Pioneer Square Labs, and Founders’ Co-op.

As organizations increasingly operate through fleets of AI agents, a new reality is emerging: humans and AI are now coworkers, but they are not yet a team.

Today’s AI agents operate in isolated sessions, with no shared memory of prior decisions, architectural intent, or team discussions. In practice, that means every task starts from scratch, forcing teams to constantly restate context and correct drift. The result is misalignment that compounds across the system, amplified at machine speed.

SageOx is building the missing context infrastructure to solve this problem. The platform captures context where it naturally occurs, across conversations, chat, coding sessions, and existing tools, and turns it into structured knowledge that flows into every new agent interaction. In practice, this means agents can pick up work with full awareness of prior decisions, generate outputs that reflect team conventions and architectural intent, and stay aligned as projects evolve — without constant human intervention. The result is a continuously aligned system in which decisions, intent, and history are seamlessly shared across humans and AI agents.

“As an in-person team, a lot of our best decisions happen in conversation,” said Marius Ciocirlan, CEO at Mark OS. “Before SageOx, our agents weren’t part of that; they felt remote. We had to constantly recap decisions, and things would get lost. Now SageOx keeps them in the loop automatically. Conversations turn into output in minutes. It’s fundamentally changed how we build, less translation, more collaboration.”

“We’re at the beginning of a fundamental shift in how knowledge work gets done, where teams increasingly operate as a combination of humans and AI agents,” said Kumar Sreekanti, Venture Partner at Canaan Partners. “Every major shift like this creates a new systems layer, and in this case, that layer is context. SageOx is building that foundation, and we believe it has the potential to become core infrastructure for this new era of AI-native work.”

“As teams begin operating at multiples of their traditional speed, in some cases 20x to 40x faster, their existing processes break down, and the ability to share decisions, intent, and history across humans and agents becomes critical infrastructure,” said Ajit Banerjee, founder and CEO of SageOx.

SageOx is already working with early design partners and has adopted an “open work” model, giving users visibility into how its own team builds alongside AI agents, a live demonstration of its core belief that knowledge should be continuously captured and shared.

The company was founded by Ajit Banerjee (CEO), Ryan Snodgrass (CTO), and Milkana Brace (CPO), a team with deep experience building and scaling foundational systems. Banerjee was an original member of the AWS EC2/EBS team, helped build core infrastructure at Apple and Facebook, and founded XetHub (acquired by Hugging Face), which now powers over 100 petabytes of data. Snodgrass was one of Amazon’s first engineers and helped lead its transition from a monolithic architecture to microservices, later scaling cloud systems that support tens of millions of Kindle devices and earning more than 35 patents. Brace is a repeat founder and former EVP of Product at Remitly, where she helped guide the company through rapid growth following the acquisition of her startup, Jargon. The team is rounded out by Galex Yen, a veteran builder, leader, and entrepreneur, with advisors including author Steve Yegge and researcher Dr. Rupak Majumdar.

SageOx will use the new funding to continue developing its product and make a small number of key hires while remaining intentionally lean and relying heavily on agentic teammates. The company sees itself as building a foundational layer for AI-native work, much like cloud infrastructure defined the last generation of software.
