- **Entity Type**: Private, venture-backed (total funding $131.5M)
- **Headquarters**: London, United Kingdom
- **Founded**: 2015
- **Founders**: Not publicly disclosed

## Core Business
- **Primary industry**: Sales Intelligence / B2B Data
- **Target customers**: Enterprise and mid-market sales, marketing, and revenue operations teams (B2B, especially those prospecting into EMEA)
- **Mission or purpose**: “Making data more usable” – helping teams become fluent in their data so they can find the right people, move faster, and grow without guesswork.

## Products & Services
- **Sales Intelligence**: Contact and company data with phone-verified mobiles, decision-maker coverage, and actionable signals (intent, hiring, funding).
- **Data-as-a-Service (DaaS)**: Real-time access to verified B2B data via API or batch delivery, powered by a proprietary data fusion engine that combines news, registries, and third-party sources.
- **Data Enrichment**: Fill gaps in CRM/marketing databases, prioritise ICP segments, and keep records accurate with continuous refresh (30-day cycle for director+ data).
- **CRM Enrichment**: Automatically enrich inbound leads so records are complete and routable from the moment they enter the CRM.
- **Compliance Layer**: GDPR and CCPA compliant data sourcing, strong Do-Not-Call coverage, ISO 27001 and SOC2 framework alignment.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Annual revenue of ~GBP 32.9M (LinkedIn estimate); total funding of $131.5M across 10 rounds

## Competitive Advantages

- **Phone-verified data**: Additional verification layers on mobile numbers result in up to 3x higher connect rates.

## Strategic Focus
- Raising the standard for B2B data quality and compliance.
- Expanding platform capabilities (signals, enrichment, API) to cover the full data lifecycle.
- Scaling internationally while maintaining a “data fluency” approach – precision over volume.

## Why Work Here
- **Culture**: Values include “deeply understand our customers,” “own the outcome together,” and “celebrate impact wherever it comes from.” Emphasis on trust, ownership, and collaboration.
- **Global team**: Employees across 20 countries with offices in London, Boston, Paris, Cologne, Skopje, and Zadar. Likely hybrid/office-based depending on location.
