💡 Role Description

As our first dedicated data hire, you’ll build the analytics foundation that helps us understand what’s really driving the business - what users love, what makes customers retain, where deals are won/lost, and where we should focus next. This is a foundational role with massive visibility and ownership.

🔧 Sample set of projects

• Feature adoption & engagement analysis: identify which features drive retention and which are dead weight - slice by firm type, user role, and tenure to give our Product team clear prioritisation signals.

• Churn & health scoring: build a customer health model that scores accounts by risk using product usage signals (logins, feature depth, search volume) and flags at-risk accounts to Customer Success before they churn.

• CRM data quality & enrichment: audit and clean our CRM data, build pipelines to keep it in sync with product usage, and ensure our Sales team always has accurate, up-to-date context on every account.

• Sales funnel analysis: map our full acquisition funnel from first touch to closed-won, identify where deals are stalling, and surface the product usage patterns that predict conversion.

• Executive reporting: build a weekly data digest for leadership covering revenue, usage, pipeline health and key anomalies - replacing ad hoc spreadsheets with a reliable, automated view of the business.

🔥 About You

We’re looking for a data scientist who loves getting into the detail of how a product is actually being used and translating that into decisions:

• Based in LDN, and excited to be in office 5 days / week

• Strong data analytics skillset

  • SQL

  • Python for data wrangling, analysis and visualization (pandas, matplotlib / plotly etc)

  • BI or dashboarding tool - Metabase, Looker, Tableau, or similar

• AI-forward: experience vibe coding and using AI tools

Relevant prior experience

• Has worked with product analytics platforms like Amplitude, Mixpanel, or equivalent - comfortable with event-level data and funnel analysis

• Experience working directly with CRM or similar data

• Bonus points for experience in B2B SaaS, fintech, or enterprise software where usage data is complex and customer segments vary widely

• Strong communicator who can tell a clear story with data - our commercial stakeholders are smart but non-technical, and they’ll rely on you to make the numbers make sense

Self-directed and comfortable with ambiguity - there’s no existing data team to hand off to; you’ll define the questions as often as you answer them

Why This Role

• Real ownership: You’ll be the first data hire. You’re not inheriting legacy dashboards or maintaining old reports - you’re building the foundation from scratch.

• Direct impact: Your work will influence product roadmap, sales strategy, customer success, and executive decision-making.

• Massive upside: We’re already at $15M+ ARR and scaling quickly. The systems you build now will support the next 10x of growth.

• Strong business fundamentals: Profitable, bootstrapped, and growing fast - no investor theatre, no fluff, just real traction.

  🌵 Benefits

  All the usual benefits (competitive pay, equity, etc) +

  • • Private health insurance
    • Gym membership (Third Space)
    • Dinner in office
    • Frequent team offsites (Crete 🇬🇷, Upstate NY 🇺🇸, Cancun 🇲🇽)
