A FAIR LOOK
Pay-for-performance pricing that transfers risk
On their appointment-setting model you pay only for qualified meetings that actually happen, at $800-$1,000 per kept appointment. For buyers who cannot commit to a retainer, that removes real financial risk.
Enterprise technology pedigree since 2010
Fifteen-plus years selling into complex tech accounts, with client logos including Cisco, IBM, HPE, Dell, Palo Alto Networks, and Splunk. Clutch lists 70% of their client base as enterprises over $1B. That is a real track record in hard rooms.
Deep cybersecurity and networking specialization
They work B2B technology only... cybersecurity, networking, big data, SaaS, IT services. Their SDRs are trained for large deal sizes and multi-stakeholder buying committees, and the logo wall shows it.
Services most SDR agencies don't carry
Event audience acquisition, channel partner recruitment, sales recruiting, SDR training, and database validation sit alongside the core SDR work, backed by a real-time client portal with 24/7 access to leads and call notes.
SIDE BY SIDE
You're not comparing Leadium to a software platform you still have to run. You're comparing a fully-managed standard.
Execution
100% US-Based SDRs
Every rep calling, emailing, and repping your brand is US-based and US-employed—not offshore labor priced to look cheap. That means clean compliance, no accent barrier on a complex enterprise call, and people who sound like the buyers they're reaching. The conversations that close happen human-to-human, in-market.
Accountability
Founder-Led, Not Farmed Out
The founders are in every account as strategic leads you're not handed three layers down to a junior account manager learning on your budget. The people who built Leadium are accountable for your pipeline, and the team runs as a specialized POD so quality never hinges on one rep having a good week.
Terms
Transparent Pricing, Month-to-Month
Published pricing, no annual lock-in, no padded retainer hiding labor arbitrage. You see exactly what you pay and you can leave anytime. Which means Leadium has to earn the relationship every single month. Most of the category buries price and locks you in. We do the opposite.

The founders in every account
Directly accountable as strategic leads, not an assigned account manager three layers down
Transparent, published pricing with no setup fee
Versus the category norm of quote-gated tiers, setup fees stacked on retainers, and 3 to 12 month minimums... Leadium is one flat, published range, month-to-month from day one.
Fully-managed, not a platform to run
You get an outcome, not a tool you still have to operate yourself. The result lands finished, ready to use, without you having to learn a new interface first.
Specialized POD model
Research, messaging, dialing, and management handled by specialists, so there's no single point of failure when one person is out.
BEST FIT
Who each one is really built for
Inside Sales Solutions fits enterprise and mid-market B2B technology companies with $15K+ deal sizes and $10K+/mo budgets that want pay-per-appointment risk transfer or a dedicated SDR pod, and can accept quote-gated pricing, undisclosed contract terms, and a partially international delivery team.
Leadium is best for
B2B teams that want a 100% US-based, high-touch SDR program with founder-level accountability, transparent month-to-month pricing, and a team that runs the whole motion for them. Especially for complex, multi-stakeholder sales where the quality of the human conversation decides the outcome.

FAQ
Leadium vs Inside Sales Solutions, answered.
Is Leadium or Inside Sales Solutions cheaper?
Leadium, in most scenarios... and Leadium's price is published while ISS's is quote-gated. Inside Sales Solutions benchmarks $800-$1,000 per kept appointment or dedicated SDRs from about $8,500/mo, with a $10,000+ minimum project size listed on Clutch. Leadium runs $3,500-$5,000/mo flat with a minimal setup fee ($250-$500). Ten ISS appointments a month costs $8,000-$10,000; a full Leadium multi-channel program costs less than that ceiling.
Does Inside Sales Solutions use US-based SDRs?
Largely, but not exclusively, and not as a written guarantee. ISS is headquartered in St. Petersburg, Florida with a New York office, and its own site lists a remote team in London. Their positioning is 'delivered by tech-sales experts', not 100% US-based. Leadium guarantees it: 100% US-based, US-employed SDRs on every account.
What's the main difference between Leadium and Inside Sales Solutions?
Inside Sales Solutions is a B2B-technology-only agency built around two models: pay-per-kept-appointment setting and dedicated SDR retainers, scoped case by case in consultation. Leadium is a fully-managed multi-channel SDR program with published flat pricing ($3,500-$5,000/mo), month-to-month terms, human-sourced data included, and the founders as strategic leads on every account. One sells scoped programs to tech enterprises; the other sells a transparent, complete outbound program.
Which is better for complex B2B sales, Leadium or Inside Sales Solutions?
Both are built for complex sales. ISS has real enterprise-tech depth... 15 years of cybersecurity, networking, and SaaS work for Cisco-class logos, and if you need event audience acquisition or channel recruitment they carry it. Leadium's structural edge is continuity and pattern depth: founders in every account since 2016, 1,500+ companies across 45+ industries, and a US-employed team executing phone, email, and LinkedIn as one program.
Does Leadium require a long-term contract?
No. Leadium is month-to-month with no lock-in. Inside Sales Solutions does not publish its contract terms... they are set per engagement in consultation, and Clutch lists a $10,000+ minimum project size. Their pay-per-appointment model does reduce commitment risk, which deserves credit, but the terms themselves are not public.
How long does it take to get started with Leadium vs Inside Sales Solutions?
ISS markets results 'within a matter of days', while third-party research reports typical ramps of 90-120 days for their programs... plan for the longer number and verify at signature. Leadium programs go live in a matter of weeks with a minimal setup fee ($250-$500).
What kinds of companies use Leadium?
Leadium works with B2B companies that want a US-based, high-touch SDR team to run multi-channel outbound, especially those with defined ICPs, meaningful deal values, and complex sales where the human conversation matters. It has served 1,500+ companies across 45+ industries, with particular strength in SaaS and technology.
