Overview

What is Inside Sales Solutions?

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.

How Inside Sales Solutions compares

Compared to larger outsourced sales organizations like MarketStar or broad-based BPO firms, Inside Sales Solutions is a more specialized, boutique provider focused tightly on B2B technology and top-of-funnel sales development. This can translate into greater domain expertise in areas such as cybersecurity and enterprise networking, as well as more tailored messaging and targeting for complex tech buyers.

When evaluated against other SDR and lead generation agencies such as CIENCE, SalesRoads, memoryBlue, or FunnL, ISS competes on its combination of pay-for-performance appointment-setting, dedicated SDR models, and sales data services. Some competitors may offer more standardized packages, broader geographic coverage, or richer published customer reviews, while ISS emphasizes flexible engagement structures, the ability to plug into a client’s tech stack, and a long track record with major enterprise tech brands. For buyers prioritizing a human-led, tech-focused SDR partner over a pure-play software solution or AI-only outreach provider, Inside Sales Solutions can be a strong fit.

Frequently asked about Inside Sales Solutions

The short version is on the surface. Open any question to go deeper.

Inside Sales Solutions is a B2B sales development and lead generation agency that helps technology companies build qualified sales pipeline. The company provides outsourced SDR teams, pay-for-performance appointment setting, lead qualification, sales data management, event audience acquisition, and related marketing services, with a strong focus on complex B2B tech markets such as cybersecurity, SaaS, IT services, networking, and big data.
Inside Sales Solutions prices its services on a custom basis depending on your goals, target markets, sales cycle, and the mix of pay-for-performance versus dedicated SDR resources. In its own sales outsourcing pricing guide, the company notes that reputable US-based providers typically charge around $800-$1,000 per kept appointment for pay-per-appointment programs, and that dedicated SDR models often start around $8,500 per month per SDR. Actual ISS pricing is scoped during a consultation based on the specific program design.
Key capabilities of Inside Sales Solutions include pay-for-performance appointment setting, dedicated outsourced SDR teams, lead qualification and nurture programs, strategic cold calling, account-based outreach, event audience acquisition and follow-up, database validation and enrichment, sales data management, channel partner recruitment and enablement, inbound lead response support, sales recruiting and SDR training services, and a real-time client portal for visibility into leads, call notes, and performance metrics.
Inside Sales Solutions competes with other outsourced SDR and lead generation providers such as CIENCE, SalesRoads, memoryBlue, MarketStar, and FunnL, as well as with in-house SDR teams and newer AI- or software-driven outbound platforms. Buyers typically compare these vendors based on specialization in B2B tech, pricing models, geographic reach, tech stack compatibility, and the balance of human-led versus automated outreach.
Inside Sales Solutions can be a strong fit for smaller B2B technology companies that sell higher-value solutions and need to quickly build pipeline without hiring an internal SDR team. However, its services are generally optimized for organizations with larger deal sizes (often $15K+ annually) and multi-step sales cycles. Very small businesses with low contract values or purely transactional, high-volume sales may find that ISS's outsourced SDR model is more than they need and may be better served by lighter-weight tools or in-house efforts.
