Marketing
Founding Marketer
About the role
Crimson is the AI case intelligence platform for litigation and arbitration. We help disputes teams at leading law firms understand large case files, test arguments and produce high-quality work grounded in the full matter record.
Crimson is expanding from London and New York at a moment when AI is reshaping how legal work is delivered. We have strong customer advocacy, a clear vertical focus and an ambitious goal: to become the defining technology company for litigation worldwide.
As our first marketing hire, you will turn that momentum into a repeatable growth engine. You will work directly with the founders across positioning, content, customer storytelling, launches and field marketing, while building the systems and standards for the team that follows.
What you'll do
- Own Crimson's positioning, messaging and voice for litigation partners, associates, innovation leaders and law firm executives
- Create authoritative content on AI and disputes, from customer stories and product launches to reports, events and executive communications
- Build a focused demand-generation programme for complex enterprise sales in the UK and US
- Develop customer advocacy with leading law firms while respecting confidentiality and the sensitivities of high-stakes matters
- Partner with sales, product and litigation specialists to turn market insight into campaigns and sharper product narratives
- Establish measurement, channel discipline and a high-quality marketing operating cadence
- Select and manage specialist partners, then help hire the marketing team as Crimson grows
What we're looking for
- A track record of producing excellent B2B marketing for a technical or expert audience
- Exceptional writing and editorial judgement, with the ability to make complex ideas precise and compelling
- Experience owning projects from strategy through execution rather than coordinating from the sidelines
- Commercial judgement and an understanding of long, trust-led enterprise buying cycles
- High standards, low ego and the pace to thrive in an ambitious early-stage company
Especially useful
- Experience in legal technology, enterprise AI, professional services or another high-trust category
- Experience building a new category or an early marketing function
- An existing understanding of law firms, litigation or the US and UK legal markets
The opportunity
Crimson is backed by Y Combinator and other leading investors and is already used by litigation teams in the UK and US. You will join a small, multidisciplinary team with direct access to customers, real ownership and the chance to help build a defining company in legal AI.
This is a full-time role based in London or New York. We work together in person at least four days a week and offer a competitive salary plus meaningful equity.
