Context is King is back for a fourth edition. After sold-out events in San Francisco and in the Nordics, we're continuing what makes this series work: real implementation stories from engineers building at the AI frontier.

The focus is on context engineering for AI agents: the discipline of designing what information an agent has access to and how it uses it. Context windows, tool use, memory, retrieval, MCP, agent harnesses — the playbook is being written in real time.

We're bringing engineers from companies building at the frontier to break it down. Expect implementation stories and live demos.

🎤 Talks & demos

Itai Smith, Member of Technical Staff, Chroma: Context-1

A live preview of Chroma's specialized 20B-parameter agentic search model — frontier-level retrieval at a fraction of the cost and up to 10× the inference speed.

Bernardo García del Río, Co-Founder & AI Lead, Flow AI: Harness is King: How we specialized our harness for data-heavy analytical agents

A look at the harness Flow AI built for production data agents — search structure, memory pointers, multi-tenancy.

Romain Sestier, Founder & CEO, StackOne: The integration layer for AI agents

A demo of building production integrations for AI agents.

Otso Veisterä, Founder, The Token Company (YC W26): Context compression without quality compression

A demo about the effects of compressing context for real-world use cases.

Nathan Burg, Co-Founder & CPO, GitHits: Source-grounded context for coding agents

A pure-demo session walking through GitHits' two primitives: canonical code examples with citations to upstream libraries, and live code navigation over open source codebases.

👋 About the organizers

Aiven makes it simple to build on open source data infrastructure - Kafka, PostgreSQL, ClickHouse, OpenSearch, and more - in all clouds. Run your apps where your data lives with Aiven Apps, and give your teams and agents the context they need with Aiven DataHub.
Flow AI builds the infrastructure layer that lets data and analytics SaaS companies deploy AI agents directly on their production data — with structured query execution, semantic data layer, and multi-tenant isolation.
