SageOx Raises $15M Seed to Build Context Infrastructure for AI-Native Engineering Teams

Startups today are bolting AI onto workflows like somebody duct-taping a flamethrower to a shopping cart and calling it “enterprise transformation.” Fast until the wheel comes off. Loud until the room catches fire. Then everybody’s standing around Slack asking why the AI agent just pushed broken code into production while half the team was asleep and the other half assumed “the AI handled it.”

Seattle-based SageOx raised $15M in Seed funding led by Canaan Partners, with A.Capital, Pioneer Square Labs, and Founders’ Co-op backing the round. But this isn’t just another AI funding headline drifting through the feed between cold outreach pitches and recycled “thought leadership” written like hostage notes from ChatGPT.

Ajit Banerjee, Ryan Snodgrass, Milkana Brace, and engineer Galex Yen are building shared context infrastructure for AI-native teams. Not another wrapper. Not another copilot with a polished landing page and trust issues. SageOx is building the connective tissue between humans and AI agents so conversations, coding sessions, decisions, and intent don’t disappear every time somebody closes a tab or leaves a meeting saying, “we’ll document it later.” Which everybody knows means never.

That’s the real problem in AI-native engineering teams. Velocity without continuity becomes chaos wearing expensive sneakers. Teams are now shipping software at speeds that make traditional workflows look prehistoric. But when humans and AI agents move 20x faster, context becomes infrastructure. Without it, every sprint turns into digital archaeology inside Slack threads and abandoned Notion pages.

Ajit Banerjee helped build systems at AWS EC2/EBS, Apple, and Facebook before founding XetHub, later acquired by Hugging Face. Ryan Snodgrass, Founder & CTO, brings the engineering discipline needed for agentic environments where AI agents and humans constantly exchange work. Milkana Brace, Founder & CPO, adds the product clarity that keeps deeply technical companies from sounding like they were designed exclusively for people debating Kubernetes at breweries. And Galex Yen is helping shape the engineering foundation underneath the platform itself.

The wild part? The SageOx team has publicly discussed building systems in roughly 3 person-months that historically took 7 person-years. Most companies still treat AI agents like caffeinated interns that occasionally hallucinate production outages. SageOx sees the bigger shift. Humans and AI agents are becoming coworkers. Coworkers need memory, alignment, and shared understanding or everybody moves faster straight into a wall.

That’s why this round matters. The future AI stack won’t belong only to whoever builds the smartest agents. It’ll belong to whoever builds the environment where humans and agents can actually operate together without losing the plot halfway through the process. SageOx is building for that future now. Quietly. Precisely. And Seattle keeps producing infrastructure companies that whisper first and dominate later.
