## Job description

## About Kernel

Agents are starting to sell, buy and operate on behalf of companies. But before an agent can close a deal, qualify an account, route a lead or assess risk, it has to answer a basic question: which company is this?

Today, that answer is messy, and no one answers it reliably. Business identity lives across CRMs, ERPs and third-party datasets full of duplicates, missing parent companies, stale addresses and incorrect enrichment. The cost shows up across the enterprise: sales teams miss revenue opportunities because they lack the right account context; operations teams take on avoidable exposure because risk signals are fragmented or wrong; and finance teams end up chasing, writing off, or defaulting on bad debt that should have been caught earlier.

Humans have worked around that mess for years. Agents cannot. They need a reliable business identity layer they can trust.

Kernel is building that layer: the business registry for agents. We issue a permanent KERN ID for every business, plus the context an agent needs to act on it. Ops, data and revenue teams at Gong, Legora, Mistral, Canva and Checkout already use Kernel on their own systems. Agents are next, and there will be far more of them.

We have raised $14M from top VCs and operators at Plaid, OpenAI, Slack and others, and we are growing 5x YoY.

## The role

You’ll be Kernel’s Founding Product Designer, shaping how people experience Kernel and building a product they’ll love to use.

Your mission: simplify complexity. Make a powerful product feel effortless: clearer workflows, sharper mental models, fewer decisions, more confidence.

## What you’ll do

- Own core UX end-to-end: flows, IA, interaction design, and visual craft.
- Run ground-truth discovery: lead user interviews, synthesize fast, turn insight into shipped changes.
- Prototype quickly: use whatever gets to a high-signal prototype (Figma, v0, Figma Make, code, etc.).
- Ship with engineering + PM: tight loops, high quality in production, iterate fast.
- Build the design foundation: principles, patterns, lightweight system - without slowing the team down.
- 5% “other stuff”: occasional help with decks/narrative when it moves the business.

## What we’re looking for (impact > seniority)

- Founding designer experience is a plus, but not a requirement - what matters most is that you have early-stage startup experience and can point to tangible examples of transforming a business through design.
- You’ve shipped meaningful product work and can walk through decisions + outcomes.
- You’re strong at simplifying complexity (not just polishing UI).
- You can run discovery independently and get to the truth.
- You move fast, communicate clearly, and collaborate tightly with engineers.
- You have taste and execution: prototype → production details.

⚠️ This role may not be for you if you:

- Need other designers to work best.
- Need perfect clarity before starting.
- Prefer long cycles and big “reveals.”
- Want fully remote work (we move faster in-person).

## What We Offer

We will do our best to offer you a ride of a lifetime. It will not be easy, but it will be thrilling.

- 💰 Salary: £110,000 – £150,000 base + equity
- 🗓️ 24 days holiday per year + bank holidays
- 🥕 £450 Monthly Office Dinner Allowance
- ✈️ 2 weeks work-from-anywhere
- 🍼 Generous parental leave policy
- 💼 Pension plan
- 💻 Top-spec equipment and central London office
- 🎉 Team events and dinners
- 🚀 Work directly with the founders to scale the systems that power enterprise AI
- 🏆 High-autonomy, high-trust environment with a small team shipping at pace

## About Kernel

## Company Overview
- **One-liner**: Kernel provides an AI-powered agentic entity database that guarantees accurate, persistent firmographic data for revenue operations teams.
- **Entity Type**: Private (Seed stage, raised in September 2023)
- **Headquarters**: London, United Kingdom (128 City Road, London, EC1V 2NX)
- **Founded**: 2023
- **Founders**: Marcus Henglein (CEO and Co‑founder) and other co‑founders (names not publicly listed)

## Core Business
- **Primary industry**: AI‑powered data management / RevOps (Revenue Operations)
- **Target customers**: B2B – enterprise go‑to‑market teams, specifically RevOps professionals at high‑growth companies
- **Mission or purpose statement**: “Build the source of truth for enterprise AI” – turning CRM data into a reliable foundation for AI‑driven decisions.

## Products & Services
- **Kernel Platform (SaaS)**: An agentic entity database that resolves messy CRM records to unique, persistent KERN IDs. It enriches accounts with accurate hierarchies and firmographics, detects duplicates, and applies expert‑level corrections at scale. The platform continuously maintains data to align with each customer’s go‑to‑market strategy.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed.
- **Key Metric**: **Total Funding** – Seed round (September 2023) from 2 undisclosed investors; amount not disclosed. **Headcount** – 43 employees (LinkedIn, July 2025), with +123.1% YoY growth.
- **Notable Investors/Partners**: Investors from the Seed round are not named. Customers include **Gong, Navan, Remote, Zip, Cognism, and Mistral AI**.
- **Growth Signals**: 
  - Processes **petabytes** of data and runs **1.8M+ AI agents daily**; handles **7B tokens per day**.
  - Claims a **4x accuracy improvement** over legacy data tools and a **14% → 90%+ average increase in CRM record accuracy**.
  - Headcount grew from ~11 to 43 in one year, with presence in 6 countries (UK, US, Germany, Denmark, Romania, Sweden).

## Competitive Advantages
- **Guaranteed accuracy**: Kernel explicitly guarantees data accuracy; if an error is found, Kernel investigates and fixes it.
- **Persistent KERN ID**: Survives domain changes, rebrands, and acquisitions – provides a single source of truth across systems.
- **AI agents with reasoning**: Agents crawl and reason over CRM context and public sources, producing justifiable, expert‑level decisions.
- **Continuous maintenance**: Unlike one‑time data providers, Kernel updates and aligns data with each customer’s evolving sales strategy.
- **Transparency**: Every data point includes a reasoning explainer and source citation, building auditability and trust.

## Strategic Focus
- Scale the platform to become the default entity‑resolution layer for enterprise AI.
- Expand customer base among high‑growth B2B companies, particularly those with complex hierarchies and multi‑geography sales.
- Deepen AI agent capabilities for automation of RevOps workflows (territory planning, whitespace identification, account merging).

## Why Work Here
- **Culture**: “No sugar, no salt” – candid, direct feedback; “Play to win” – competitive, cross‑team intensity; “Customer Shareholders” – customer‑first mindset.
- **Work environment**: **On‑site** in a central London office with a gym, top‑spec equipment, free dinner, and regular team events. Hybrid not explicitly stated, but the Built In profile lists “OnSite Workspace”.
- **Perks**: 24 days holiday + bank holidays, work abroad 2 weeks per year, visa sponsorship, relocation bonus, employee‑friendly equity (meaningful option grants), and free dinner.
- **Engineering culture**: Early‑stage opportunity – work directly with founders, shape infrastructure for enterprise AI. The company is solving a hard data‑accuracy problem, appealing to engineers who enjoy reasoning about edge cases.
- **Growth**: High headcount growth and a strong customer roster signal a fast‑scaling startup with career acceleration potential.
