At Fifty One Degrees we're Engineers by trade. Growth Practitioners by design. We build AI-integrated revenue engines on Attio.

Most CRMs are static graveyards for data. We turn Attio into the high-velocity central nervous system of your business.

Based in London (Great Portland St) and New York (Broadway), Fifty One Degrees serves UK & US businesses with turnovers between £5m and £250m. We practice Radical Candour, and we don't care about billable hours; we care about tangible, measurable impact.

Founded by tech veterans who have scaled companies to process millions of customers and built 300-person analytics powerhouses, we understand the Legacy CRM Tax that kills growth.

We don't just set up Attio; we engineer it to automate the tedious stuff, freeing your team for creative, high-value work.

How We Work

We move at the speed of your business using our Ship, Learn, Iterate framework:

1. Discovery Call: Book a 30-minute session to audit your current GTM friction.
2. Proof of Concept (PoC): We build a functional "vertical slice" of your Attio workspace in 2 weeks to prove technical value.
3. The Build: A fully integrated, AI-augmented deployment delivered in ~6 weeks.
4. Knowledge Transfer: We are Smart Enablers. We train your team to own the system so you aren't dependent on us forever.

Our Expertise

We specialise in high-stakes environments where data integrity and automation are non-negotiable:

• Complex Migrations: Seamless transitions from Salesforce, HubSpot, Dynamics or Pipedrive without data loss or downtime.
• AI Workforce Integration: We are implementation partners for ElevenLabs, Bland AI and Relevance AI. We deploy AI agents and voice AI that handle triage and outreach directly within Attio.
• Predictive Modelling: We build custom ML models for Targeting, Lead Scoring and Churn Prediction that live inside your Attio attributes.
• Vertical Specialisation: Deep experience in Financial Services (FCA/PRA compliance), Home Improvement/Construction, and VC/Private Equity deal flow.

What We Deliver

• Architected Workspaces: Custom data models (Objects, Attributes, Lists) engineered for your specific business logic.
• Automated Workflows: End-to-end GTM loops—from inbound lead enrichment to automated outbound triggers.
• The Modern Data Stack: Bi-directional syncs between Attio and your data warehouse (Snowflake, BigQuery) using dbt and custom pipelines.
• Security & Governance: Fortified setups designed for the EU AI Act and GDPR, ensuring your data is a proprietary asset, not a liability.
