Fission chain reaction

If your profit and valuation hinge on B2B revenue, a great product alone isn’t enough. At your core, you’re building a sales company! Capturing just 1% of a $30B market means closing over 3,000 deals, requiring at least 30–90k qualified leads. That’s not something you can casually drop on your people as a target.

Real lead generation isn’t about blasting emails and hoping for hits. It’s a data-driven engine—20+ integrated tools and multiple specialised teams — developed year after year and continuously optimised. You can’t build that overnight.

Instead of pouring time and resources into reinventing the wheel, partner with us. We’ll deliver measurable results you can benchmark against, raising the bar for your internal SDRs. It’s not just about hitting a lead count; it’s about constructing a scalable, predictable revenue engine that sets you apart in a crowded market.

monitorig

We track all that could be measured to adjust our outreach strategies on the go.

Research

We analyze every aspect of your product and business history, as well as the market—including your competition—to identify ideal buyers and key decision-makers, ensuring you achieve results from the very first month.

Lead generation

We conduct simultaneous A/B testing across sales approaches, verticals, niches, seniority levels, and more to maximize active engagement with potential buyers.

Closing deals

If your team is overwhelmed by the leads we generate, we can step in and close those deals for you.

Our team will work for you with a fixed base retainer from $7,900/month paired with performance-based incentives

How does it work

Step 1.
Assembling the Sales Team

After the contract is signed and payment confirmed, we rigorously select a tailored sales team for your project. Our experienced sales experts go through several assessment stages, conducting market research, writing test pitches, and preparing an initial pipeline.

Your team will also include a dedicated lead to manage the project, a tech lead for infrastructure setup and management, and a QA specialist to ensure top outreach performance.

Step 2.
Setting up

We’ll establish a system for the most effective outreach by configuring a custom tech stack tailored to your project. Using only the most advanced tools on the market—including Clay, Crunchbase, Instantly, Apollo, LinkedIn Helper, and dozens of other databases and platforms—we create an organized and high-performing campaign setup across email, LinkedIn, and calls.

We’ll also handle creating fresh domains and specialized email inboxes to ensure optimal open and response rates.

Best of all, everything we use is the enterprise-grade, paid version, fully covered by the retainer you’ve already paid.

Step 3.
Pitches and Pipeline

Following an in-depth analysis of your market and product, we’ll craft tailored email and LinkedIn sequences designed to resonate with your target audiences.

At the same time, we’ll build an extensive pipeline of high-potential prospects and target companies, complete with detailed profiles. These profiles will include each prospect’s role, company description and size, contact details, LinkedIn profile, and even funding rounds, when relevant.

All of this ensures we’re reaching the right people, in the right places, with the right message.

Step 4.
Launch

We’ll launch multi-channel outreach campaigns tailored to your needs, whether you’re focused solely on lead generation or engaging us as your closing sales power. For lead generation, we’ll track daily metrics to maximize engagement and build a steady pipeline of qualified prospects.

If you engage us to close deals, our team will take the next step—scheduling and conducting calls with your potential clients, pitching your solution, and guiding them to signed contracts. We’ll also handle objections, turning hesitations into opportunities through feedback or further discussions.

No matter how you choose to work with us, you’ll have full visibility into every action we take, ensuring seamless alignment with your goals.

Step 5.
Reporting and Analysis

You’ll receive detailed daily, weekly, and monthly reports outlining our progress. We’ll also hold weekly calls with you and set up a dedicated messenger group to stay connected at all times—answering your questions and discussing all project-related topics.

At the same time, we’ll continuously analyze outcomes, test new approaches, and explore fresh hypotheses to achieve our ultimate goal: closing deals and driving results for your business.

SLSBMB breaks ice,
walls and records

(i)
Break through

(2)

As you can see in your inbox, most salespeople underestimate the importance of an initial sales pitch, often relying on generic attempts to grab attention.

At SLSBMB, we know that the quality of a pitch is everything. It directly influences results more than any other factor. Decision-makers with serious budgets don’t have time to engage with people they perceive as superficial or professionally lacking.

To be part of SLSBMB, a salesperson must master the art of the pitch—crafting B2B texts at a level we call beyond godlike. These messages must be concise yet remarkably informative, avoiding the typical “salesy” tone while effectively communicating the product’s value and implications.

Thanks to our deep A/B-testing culture, we consistently deliver response rates that others might deem impossible in today’s digital landscape.

We don’t just sell lead generation.

We sell a state-of-the-art sales system.

(i)
The art of strong interaction

(3)

At SLSBMB, we go beyond lead generation to engineer sales teams that don’t just sell—they resonate. Combining creativity, data, and a deep understanding of human behavior, we craft strategies that transform hesitation into trust, conversations into partnerships, and ideas into movements.

We believe sales is both an art and a science. It’s about knowing the exact moment to act and the precise way to engage, using a foundation of insights and a culture of constant innovation.

For most companies, building a department like this takes years of trial and error. That’s why we exist: to give you an edge, delivering what others only dream of achieving. With us, you don’t just get results—you get a partner who’s as invested in your success as you are.
