## About Coworker.ai

## Company Overview
- **One-liner**: Coworker.ai builds an enterprise AI agent that autonomously researches, plans, and executes complex work across a company’s tools, powered by its proprietary Organizational Memory (OM1) architecture.
- **Entity Type**: Private (Seed stage; $13M seed round announced May 2025)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2024
- **Founders**: Alex Calder (CEO) and Bradford Church (CPO)

## Core Business
- **Primary industry**: Enterprise AI / Autonomous AI Agents / AI-powered automation
- **Target customers**: B2B, mid-market to enterprise (Sales, Engineering & Product, Customer Success, Leadership)
- **Mission**: “The world’s first general-purpose AI teammate that can research, plan, and execute complex work like an experienced colleague.”

## Products & Services
- **Coworker AI Agent**: Autonomous agent that can answer, plan, and execute multi-step tasks across 25+ enterprise tools (Slack, Jira, GitHub, Salesforce, etc.) without custom coding. Powered by OM1 memory architecture – a proprietary knowledge graph tracking 120+ business dimensions.
- **Chat**: Conversational AI across all connected systems (CRM, support, docs, code, data).
- **Cowork**: Generate polished artifacts (decks, docs, dashboards, financial models) with shared context.
- **Code**: Repo-aware coding with multi-file edits, sandboxed execution, and full org context.
- **Agents**: Long-running, permission-aware agents triggered across the stack; built in plain English.

## Market Standing
- **Valuation / Market Cap**: Not publicly disclosed (private company)
- **Total Funding**: $16.5M ($13M seed round led by Jeff Huber of Triatomic Capital, plus pre-seed from Soma Capital, Focal VC, Mischief, Karman Ventures)
- **Key Metric**: 4.9 / 5 on G2 (10 reviews); ~23 employees; 3,646 LinkedIn followers
- **Notable Investors**: Jeff Huber (Triatomic Capital), Ramtin Naimi (Abstract Ventures), Mallun Yen (Operator Collective), Tim Young (Eniac Ventures), Clark Golestani, Ken Hausman, Jack Greenfield (K2 Access Fund), Soma Capital, Focal VC, Karman Ventures
- **Growth Signals**: Launch of the first AI agent with deep company context (May 2025); customers reporting 4,000+ hours saved in initial deployment; 4 active job postings across engineering and sales; expanding from San Francisco to Atlanta office.

## Competitive Advantages
- **Proprietary OM1 memory architecture** that gives the agent deep, persistent context across a company’s data, culture, and workflows – unlike generic AI assistants.
- **Intelligent routing** across 50+ native integrations and multiple open/closed models (open source made enterprise-ready) – delivering frontier-quality output at 80% lower cost than standard frontier APIs.
- **Enterprise-grade security**: SOC 2 Type II, GDPR, CASA Tier 2, US-hosted models, permission-aware (respects existing access controls), no training on customer data.
- **No vendor lock-in**: as better models ship, agents automatically adopt them without migration or re-platforming.

## Strategic Focus
- Expand autonomous agent capabilities to every business function (sales, engineering, customer success, leadership).
- Continue adding 50+ new connectors per week and supporting more enterprise tools.
- Scale the memory architecture (OM1 → OM2) to support even richer context and cross-department collaboration.
- Maintain leadership in security and compliance to win enterprise trust.

## Why Work Here
- **Early-stage rocket ship**: Backed by top-tier investors and founded by former Uber executives. Small team (~23 people) means outsized ownership and impact.
- **Flexible work model**: Remote or hybrid with offices in San Francisco (HQ) and Atlanta, Georgia. Roles listed as “Remote or Hybrid” (Built In).
- **Engineering culture**: 40% of the team is technical. Engineers get to work on cutting-edge AI agent infrastructure, model routing, and proprietary knowledge graphs.
- **Growth trajectory**: Company is in active hiring (Software Engineer, Account Executive, Senior Account Executive, Head of Marketing). Fast-paced environment with significant autonomy.
- **Mission-driven**: Automating routine work so people can focus on meaningful, creative work. “Turning one person into a team of tens.”
