Our client's team is building an AI-first revenue platform a collective intelligence layer that connects messy, real-world data into context that AI agents can learn from and act on autonomously. The goal is simple: replace metawork with action that compounds revenue per rep less digging through dashboards, more time moving pipeline.
If you're entrepreneurial and want to help define what AI-native software looks like how data becomes context, how agents plan and act, and how chat turns into outcomes this is the place to build. The team ships in tight loops, learns in public, and measures success by customer impact

Create the collective memory
:
Ingest and unify data from multiple sources (CRM and beyond) into a semi-structured context graph that captures what leads to winning deals, modeled at multiple levels with strong tenant isolation.
Orchestrate agentic systems
:
Design planner/executor patterns, tools, and policies (including MCP-style interfaces) that turn context into content, and content into actions. Define lightweight evaluation harnesses to measure quality.
Deliver where users work
:
Expose capabilities through native surfaces (apps, chat, integrations) in tight loops with product and GTM teams reducing context-switching and metawork.
Prove outcomes
:
Partner with product and customers to define success metrics (e.g. tasks auto-completed, adoption, retention, pipeline lift, latency) and wire observability so the team can ship, learn, and iterate quickly.
Balance cost & reliability
:
Optimize accuracy, latency, and cost for agent runs and retrieval. Design fallbacks and safeguards to ensure the system remains dependable under real-world load.
Owner/builder mindset with strong product sense you frame problems, choose simple paths, and own outcomes.
