Inside Sales Solutions (ISS) is a sales development and revenue growth agency that specializes in helping B2B technology companies generate pipeline and convert more opportunities. Headquartered in St. Petersburg, Florida with additional presence in New York and a remote team in London, ISS focuses on outsourced SDR services, pay-for-performance appointment setting, lead qualification, and related marketing support to accelerate revenue for tech vendors.
Founded in 2010, the company has built its reputation around performance-based demand generation and inside sales execution for complex B2B sales cycles. ISS positions itself as a low-risk partner by offering both pay-per-appointment and dedicated SDR engagement models, allowing clients to choose between variable, performance-based programs and retained, embedded teams. Their SDRs and campaign strategists are trained to work in high-stakes technology segments such as cybersecurity, big data, SaaS, IT services, and networking, where deal sizes are large and buying committees are complex.
Beyond appointment setting, Inside Sales Solutions delivers a portfolio of services that includes lead qualification, sales data management and database enrichment, event audience acquisition and follow-up, account-based marketing outreach, sales recruiting, and personalized SDR team training. The firm emphasizes its ability to plug into a client’s existing tech stack or provide its own tools, and it provides a proprietary client portal for real-time access to lead lists, call notes, and performance reporting.
In the B2B lead generation and SDR outsourcing market, ISS competes with other specialist agencies and larger outsourced sales providers but differentiates itself through its tight focus on B2B technology, its mix of pay-for-performance and dedicated SDR models, and its experience running high-touch cold calling and multi-channel campaigns. The company has been recognized on the Inc. 5000 list and highlights work with major enterprise technology brands alongside fast-growing startups.
