What is Inside-Global?
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.

Who Inside-Global is for
A strong fit for
B2B technology, SaaS and software vendors that need to rapidly scale outbound pipeline generation across regions and languages, and want an experienced outsourced SDR partner that can operate as an extension of their sales and marketing teams.
Probably not for
Very small local businesses, B2C companies, or organisations with low deal values that cannot justify the cost of a dedicated outsourced SDR team, as well as teams that require all sales development to remain fully in-house for compliance or control reasons.
How Inside-Global compares
Compared with other outsourced SDR and lead generation providers such as memoryBlue, CIENCE, Martal Group and Belkins, Inside-Global is notably specialised in the B2B technology and SaaS space and places a strong emphasis on multilingual, multi-region execution. While many competitors focus primarily on North American markets, Inside-Global’s footprint spans EMEA, the Americas and APAC, making it particularly attractive for vendors looking to expand internationally or run coordinated global campaigns.
In terms of service model, Inside-Global offers a full-funnel approach, from data provision and list building through lead generation, nurturing and support for closing opportunities, whereas some competitors emphasise top-of-funnel appointment setting or SDR “team as a service” models. Buyers that prioritise transparent, productised pricing, standardised processes and extensive third-party review data may find firms like CIENCE or Belkins a closer fit. Conversely, organisations seeking a tech-focused, multilingual partner that can operate as a deeply embedded extension of their sales and marketing teams will likely view Inside-Global as a strong contender.
