Leadium Reviews & Provider Details

Rating: 4.8 (94 reviews)

Leadium is a boutique, 100% US-based B2B outbound sales development agency. Founded in 2016, we run managed, outsourced SDR programs across cold calling, email, and LinkedIn that book qualified meetings on your calendar. We're founder-led by design. You work directly with the people who run the company, not a junior account manager juggling 20 logos. Every client gets a dedicated, US-based SDR who learns your business, your ICP, and your value proposition, and represents you like an internal hire. Calls are recorded, transcribed, and reviewed weekly, so you hear exactly what your market is saying and we adjust in real time. We cap our active client roster on purpose. Quality outbound can't be mass-produced, so we keep the team small, US-based, and focused on a limited number of engagements. All data and work product is 100% yours. What we do: - Managed outbound SDR programs (cold calling, email, LinkedIn) - ICP definition and target account list building - Contact data enrichment - Qualified meeting and appointment generation - Email infrastructure and deliverability setup - Outbound strategy and messaging Track record: since 2016 we've built over $1 billion in qualified pipeline across 1,500+ organizations, contributed to 89 acquisitions, and supported clients who've raised $6.5B+ and reached 5 IPOs. Leadium is NGLCC-certified (LGBTBE) and consistently rated among the top sales development agencies by Clutch, GoodFirms, and Inc. 5000. Pricing is flat and month-to-month, starting at $3,500/month for a dedicated cold-calling SDR, with no hidden fees. Want US-based outbound, founder-level attention, and a rep who actually learns your business? Let's talk.

"A Trusted Team That Lets Us Focus on KOINAN’s Core Operations"

5/5

What do you like best about Leadium?

I appreciate being able to work with a team that takes ownership of an area we would otherwise need to staff and build out internally. It gives us an alternative path for expanding the business, while allowing us to stay focused on KOINAN’s core operations. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

I do not have a specific complaint to share right now. We are still working together, and I would rather have more experience with the service before deciding what needs improvement. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

Know which businesses you want to reach, and be ready to explain what makes your solution valuable to them. If your product is unfamiliar to the market, it needs a clear, straightforward explanation, so make sure you give the team enough context and information to understand your business and communicate it effectively. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

Introducing KOINAN to businesses that may not have considered coin-exchange machines before takes more than simply presenting the product. Leadium is helping us extend our reach into the business market. This gives us more room to explore where our solution could be useful beyond our existing network.

"A Great Way to Introduce Voyager to Potential Customers"

5/5

What do you like best about Leadium?

It gives us another way to introduce Voyager to potential customers. We have several services to offer, so getting our name in front of businesses that may need them is useful. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

Our services cover quite different needs, and one message will not suit every type of customer. We still need to be clear about which part of our offering is relevant to each business. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

Know which customers you want to reach before getting started. If your company offers several services, it is worth deciding which ones deserve the most attention rather than trying to promote everything at once. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

We wanted to reach more businesses that could benefit from Voyager's services and expand our reach beyond our existing network. Leadium supports that effort by helping us connect with companies that may not have come across us otherwise. This gives us more opportunities to introduce our services to potential customers, build new business relationships, and reach organizations that could benefit from what we offer.

"Purpose-Driven Conversations That Make Commercial Work Easier to Measure"

5/5

What do you like best about Leadium?

I appreciate having a commercial process that does not begin and end with someone simply receiving an introduction. There is a clear purpose behind arranging conversations, and that makes the work easier to assess from a business perspective. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

I would like to see more consistency between the initial interest a prospect shows and their understanding of what our product actually does. Those are two different things, especially in a specialised field. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

Do not treat every booked appointment as equally valuable. Think about what you want the person on the other side of the table to understand before you consider the meeting a success. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

There are accounting firms that have not yet considered how specialist AI could fit into their tax research work. Leadium is helping us start conversations with businesses in that market through its prospecting and appointment-setting work. Review collected by and hosted on G2.com.

"Adds Sales Capacity While Keeping Me Involved in Direction"

5/5

What do you like best about Leadium?

It gives us additional capacity for commercial work while we keep building the company. I can stay involved in the direction of sales without having to personally initiate every conversation. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

Interest in AI visibility can mean different things to different companies. Some are exploring the topic; others have a defined need. Making that distinction is important, and it is not something a single message can resolve for every prospect. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

Think about what happens after a meeting is booked. Decide who will handle the next conversation, assess whether there is a real business case, and keep the handover clear. That part deserves as much attention as the initial outreach. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

Leadium supports our efforts to develop new customer relationships without making every initial sales conversation dependent on my own time. That matters as aclipp grows in a market where PR measurement and AI visibility are becoming increasingly connected. Review collected by and hosted on G2.com.

"Valuable Business Development Support as We Grow"

5/5

What do you like best about Leadium?

It gives us additional capacity for business development while we continue building our own expertise and solutions. For a growing company, being able to add support in this area is useful. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

I would like to keep improving how our technical services are presented during outreach. Carbon accounting and project development are not the same offering, so the message needs to make that distinction clear. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

I would recommend defining your commercial priorities before starting. Know which service you want to develop, which market it serves, and what a useful sales conversation would look like for your business. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

Leadium supports our outbound sales efforts as we grow TruCarbon's climate solutions business. Our services range from emissions accounting to carbon project development, so our approach to reaching potential customers needs to reflect the different needs behind those services.

"Structured process for commercial development with genuine business value"

5/5

What do you like best about Leadium?

It gives us another way to pursue commercial development while we continue our consulting and training work. I see value in having a defined process for this part of running the business. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

There is no single e-commerce problem that applies to every company. An Amazon seller with declining conversion has different concerns from a manufacturer preparing to sell online, so the approach needs to reflect the situation. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

Before starting, decide what a useful sales opportunity looks like for your business. For us, a company's interest in digital commerce is only the starting point; its actual needs and plans matter too. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

Leadium is supporting our efforts to develop sales opportunities for digiPULS. Our work ranges from Amazon consulting to wider e-commerce strategy, so understanding which companies may need that expertise is important. Review collected by and hosted on G2.com.

"Dedicated Business Development Support That Helps Us Pursue New Opportunities"

5/5

What do you like best about Leadium?

I value having dedicated support for business development. It gives us a way to pursue new commercial opportunities without making every part of that work dependent on my own schedule. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

The nature of our software makes the initial explanation difficult. A company can understand the words "risk management" without necessarily recognising where its current approach could be improved. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

Be clear about the problem your software solves and who is likely to care about it. In our market, a meeting is only a starting point. The important part is establishing whether there is a real need behind the interest. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

Our market is not driven by impulse purchases. Organisations need a reason to review how they manage risk and compliance. Leadium supports our outreach to businesses that may have a need for what Quantate offers. Review collected by and hosted on G2.com.

"Great at Uncovering the Real Business Problem Before Technical Discussions"

5/5

What do you like best about Leadium?

I like that the work starts before we get into the technical discussion. With custom software, there is usually a business problem underneath the request, and that is what I want to understand. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

There are cases where the initial reason for a conversation is too general. With our kind of work, it can take a little while to understand whether there is actually a technical problem worth solving. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

I would not treat it as something you can simply hand over and forget about. You still need to know your market and be ready to take over when a conversation becomes technically serious. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

They take care of a part of business development that is difficult to keep consistent when you are also running software projects. It gives Visito a regular sales activity without making it another job for me. Review collected by and hosted on G2.com.

"Dedicated Market Development Team Frees Up Engineering Time"

5/5

What do you like best about Leadium?

I like having a separate team working on the initial market development. It means our engineers and leadership team are not spending their time trying to turn every potential contact into a qualified conversation. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

There is a fair amount of education involved with our technology. Someone can understand the general idea of stratospheric monitoring but still need context before they see where it fits into their existing systems or operations. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

It makes the most sense when you already know the type of customer you want to reach but need more activity around that market. For an emerging technology, I would also make sure the outreach team has enough context to explain the use case rather than just the technology. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

Our technology has applications across several industries, but the actual buyers are very specific. Leadium gives us more coverage in identifying organizations with genuine monitoring or intelligence needs instead of relying entirely on our own network. Review collected by and hosted on G2.com.

"A Clear Framework for Pursuing Outbound Sales"

5/5

What do you like best about Leadium?

It gives us a way to pursue outbound sales as a defined activity. That is useful for a specialist business where the audience is narrower than the wider legal services market. Review collected by and hosted on G2.com.

What do you dislike about Leadium?

Our service cannot be explained properly through a label alone. Prospective customers need to understand the practical purpose of the agreements, not just that we provide contracts. Review collected by and hosted on G2.com.

Recommendations to others considering Leadium:

Be precise about what makes a prospect suitable for your service. If that definition is vague, it becomes harder to judge whether the people you reach are relevant to the business you are building. Review collected by and hosted on G2.com.

What problems is Leadium solving and how is that benefiting you?

Leadium supports our business development through B2B lead generation and appointment setting. ITagree serves a defined group of technology providers, so our outreach needs to reflect the particular business issues our agreements are designed to address. Review collected by and hosted on G2.com.
