Inside-Global (often branded simply as "inside global") is a UK-founded, globally operating SDR and inside sales outsourcing agency focused on helping B2B technology, SaaS and software vendors accelerate revenue growth. The firm provides on-demand sales development teams that act as an extension of clients’ own sales and marketing organisations, delivering appointment setting, lead generation, lead nurturing and opportunity management services across EMEA, the Americas and APAC.
Founded in 2010 in London by two co-founders, the company was originally known as Inside Marketing before rebranding to Inside Global in 2021 to reflect its international footprint and multilingual capabilities. Over more than a decade, it has expanded from a small London-based shop to a multi-office operation with locations in the UK (London, Liverpool, Birmingham), the US (Raleigh, NC), Germany (Berlin) and Australia (Perth). Its leadership highlights decades of combined experience building sales development programmes for thousands of technology companies worldwide.
Inside-Global differentiates itself through a strong focus on the B2B tech segment, a proprietary database of more than 50 million sales-ready contacts, and a modern tech stack that incorporates Salesforce, ZoomInfo, LinkedIn Sales Navigator and AI-powered intent data. Its services span the full sales funnel under the mantra “Create. Nurture. Close.” – from top-of-funnel outbound prospecting and MQL/SQL generation, to lead nurturing, pipeline development, and support for closing opportunities. Campaigns are executed through a multi-channel mix of phone, email, social, LinkedIn outreach, and event-driven programmes.
Positioned in the outsourced SDR and lead generation services market, Inside-Global competes with other specialised providers and larger outsourced sales firms, but leans heavily on its tech-vertical specialisation and multilingual reach. The company is recognised in industry rankings and has won awards including listings among UK B2B marcomms agencies and best small companies to work for. Its client base includes global enterprises and high-growth SaaS firms, and case studies highlight significant pipeline and ROI impacts for customers.
