## Job description

## About HASH

HASH is building an open-source platform for structured knowledge and organizational decision-making. We turn information from databases, applications, documents, communications, sensors, and other sources into continuously updated knowledge and process graphs. From this shared model, organizations can analyze their operations, simulate possible futures, automate workflows, and give AI agents the context they need to act reliably.

Our [mission](https://hash.ai/about/mission) is to solve information failure and enable everybody to make the right decisions. We work on difficult technical and commercial problems, including applications in regulated and safety-critical environments.

## About the role

In the last six months we’ve seen significant growth and are now scaling fast. We have working technology, customer results and senior people who can run strong discovery and technical conversations. We’re hiring our first Outbound Business Development Lead to create a much larger and more systematic flow of the right people into those conversations.

Your job is to identify organizations that could run valuable HASH pilots, find the right stakeholders, form a credible hypothesis about where we could help, contact them cold and turn interest into qualified meetings.

This is a zero-to-one role. Marketing will not hand you a full pipeline, and a manager will not hand you a finished call list or script. You will build the outbound motion yourself: targeting, research, data, tooling, messaging, cadences, qualification, CRM and measurement. You’ll work directly with HASH’s founder, Enterprise Sales Lead and Solutions Lead, and use the conversations you create to improve the system quickly.

## Requirements

- A record of personally creating qualified B2B meetings from cold accounts, rather than only working inbound leads or an existing network
- Excellent concise writing: your outreach should sound like a smart person with a relevant idea, not an automated sequence
- Strong account-research ability and the judgment to find a specific operational hypothesis in incomplete public information
- Comfort with cold email, phone, LinkedIn and persistent follow-up, without sacrificing relevance or respect for the prospect
- Fluency with CRM, enrichment, sequencing, automation and AI-assisted research; you know how to gain leverage without producing generic spam
- Enough curiosity about AI, data and complex operations to understand what HASH does and where it may create material value
- High agency, energy and organization, with the ability to build a function without waiting for detailed instructions

Experience in enterprise AI, data infrastructure, developer tools or other technical B2B software is useful. So is exposure to supply chains, manufacturing, life sciences, chemicals, logistics, energy or other operationally complex industries. Excellent written and spoken English is essential; German or another European language is valuable.

## What you'll do

- Identify industries, companies and operational situations in which a HASH pilot could create measurable value
- Build and maintain target-account lists, stakeholder maps and useful segmentation
- Find executives, operators, transformation leaders and technical champions who own the relevant problems
- Research each account deeply enough to create a credible, specific reason to engage
- Own cold email, phone, LinkedIn and other outbound channels end to end
- Develop and test messaging, cadences, triggers and offers for different accounts and personas
- Qualify prospects and book focused meetings for discovery and demonstrations
- Prepare an account brief for every meeting, including the likely problem, participants, context and proposed angle
- Attend selected meetings, capture objections and buying signals, and feed what you learn back into targeting and messaging
- Maintain excellent CRM hygiene, execute every follow-up and report honestly on funnel performance
- Measure conversion by segment, persona, trigger, channel and message, and change course when the evidence warrants it
- Build the playbook and, as the function grows, help hire and train the people who follow you

Success is qualified meetings held with people and organizations that could plausibly run a valuable HASH pilot, and the rate at which those meetings become accepted opportunities. Raw activity is a diagnostic, not the goal.

## Why HASH

- We've raised $5.5m+ from Silicon Valley VCs, and have contracted >$10m in revenue in the last 18 months. Our founding team have established and sold companies for tens of millions, hundreds of millions, and billions of dollars (including household names like Trello and Stack Overflow)
- Build the first outbound motion around technically differentiated, open-source AI infrastructure
- Work directly with the founder and the people building and deploying the product
- Influence which markets we pursue, how we explain the technology and what we build next
- Join at a moment of rapid growth, with outsized scope and influence
- Be part of a high-agency team that cares about output, ownership and quality

This role is probably not for you if

- Your experience is limited to operating mature functions with established teams and processes
- You want to oversee an outbound process but do not want to execute on it personally
- You need problems to be carefully defined before you begin working on them
- You prefer consensus to making a timely decision
- You want a narrow remit with predictable boundaries
- You are not interested in understanding a deeply technical product
- You simply want to scale an existing process, rather than develop, execute and iterate on strategy from the ground-up

## Benefits

A base salary will be offered of £65,000-90,000 in London.

Compensation in this role is extremely heavily performance-based, with generous equity/bonus offered in addition to the base salary, in order to align incentives.

## About HASH

## Company Overview
- **One-liner**: HASH is an open-source platform for decision-making that integrates live data, constructs ontologies, and creates shared understanding through collaborative agent-based simulation and knowledge modeling tools.
- **Entity Type**: Private (Seed stage)
- **Headquarters**: London, United Kingdom
- **Founded**: 2019
- **Founders**: Joel Spolsky and Jude Allred

## Core Business
- Primary industry/industries: Technology, Information and Internet; Business Decision-making Software; Simulation & Modeling
- Target customers: B2B, Enterprise (with a focus on safety-critical supply chain, biopharmaceutical logistics, and complex systems modeling)
- Mission or purpose statement: "Eliminate information failure and help everybody make the right decisions."

## Products & Services
- **[HASH Platform (hash.ai/hash.dev)]**: An open-source, collaborative workspace for structured knowledge that integrates live data, enables ontology construction, and provides fast, distributed agent-based simulation. Combines knowledge capture and modeling tools for complex systems decision-making.
- **Block Protocol (blockprotocol.org)**: An open standard they drive for interoperable, data-driven blocks, contributing to the commons.
- **Open Source Simulation Engine**: Built in Rust/WASM, focused on agent-based simulation and formal verification of distributed systems.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metrics**: Annual Revenue of approximately $1 million; Total Funding of $2.5 million (1 seed round)
- **Notable Investors/Partners**: Zetta Venture Partners (Lead), Root Ventures, with 6 total investors in the seed round. They also work with the Advanced Research + Invention Agency (ARIA) and scientists from the University of Oxford.
- **Growth Signals**: Headcount grew 14.3% YoY (now 9 employees); actively recruiting for new engineering and research roles; conducting high-profile research programs with ARIA and Oxford on safety-critical supply chains; 2,460 LinkedIn followers with 15.6% yearly growth; employer rating of 5.0/5.0 on Wellfound.

## Competitive Advantages
- **Unique Open-Source Approach**: All core tools are open source, building trust and allowing external validation—rare in the decision-modeling space.
- **Technical Moat**: Combines graph-backed world models, formal verification, and agent-based simulation (Rust/WASM) with AI research. Very few companies operate at this specific intersection.
- **High-Impact Focus**: Working on genuinely hard problems (eliminating information failure) with safety-critical applications (supply chains, biopharma logistics), giving them a defensible niche.
- **Elite Talent Sourcing**: Proactively identify and hire exceptional people through their own tooling and community, not just open applications.

## Strategic Focus
- Current priorities: Building a next-generation platform for decision-making via graph-backed world models and AI; expanding into safety-critical supply chain management with government and research partners; advancing their open standard (Block Protocol).
- Direction for growth: Scaling the engineering team (Rust, TypeScript, Python), deepening AI research (graph learning, formal verification), and expanding use cases in complex systems simulation.

## Why Work Here

- **In-Person Focus**: Operates in-person from offices in **London** (HQ) and **Berlin**, with company-wide get-togethers at least twice a year in Europe. Some remote flexibility is available (e.g., Full-Stack Engineer roles can be in-office or remote).
- **Compensation & Perks**: "Leading compensation" with meaningful equity, competitive salaries, an 'unlimited' equipment and learning allowance, and at least 30 days paid time-off each year.
- **Engineering Culture**: Work on hard problems in Rust, TypeScript, and Python, including formal verification, graph learning, and simulation. They emphasize a fast, conviction-based hiring process with decisions made "within days, not weeks."
- **Hiring Process**: A short introductory call followed by a focused work sample or technical deep-dive. Most hires begin with HASH reaching out, but candidates can apply for specific roles.
