The problem

Are you currently dealing with...

A strong offer and no reliable way to fill the calendar?

Not Enough Leads
  • Your team has spare capacity, but there are not enough opportunities to keep them busy.
  • Calendars have empty slots, machinery sits unused, and delivery capacity goes to waste.
  • Revenue targets depend on a small number of deals, putting pressure on every sales conversation.
Leads Cost Too Much
  • Your cost to acquire each customer keeps increasing.
  • After cost of goods, sales costs, and marketing spend, there is little profit left.
  • You need a high close rate just to recover what you spent generating the opportunity.
Low-Quality Leads
  • Too many enquiries come from price shoppers, low-budget prospects, and people who are not ready to buy.
  • Your team spends time following up with leads that never become serious sales opportunities.
  • You feel pressured to lower prices or compete with freelancers and cheaper providers.
Unpredictable Lead Flow
  • Some months are busy, while others are unexpectedly quiet.
  • Revenue becomes difficult to forecast because the number of opportunities keeps changing.
  • You move through feast-and-famine cycles that make hiring, planning, and investing harder.
Over-Reliance on One Channel
  • Most new business comes through referrals, word of mouth, or a single marketing channel.
  • You cannot control when the next opportunity arrives or how many leads you receive.
  • A slowdown, algorithm change, or loss of a referral partner can quickly affect your pipeline.
Too Much Manual Prospecting
  • You spend hours researching companies, finding contacts, sending messages, and following up.
  • Your sales team spends more time creating opportunities than speaking with qualified buyers.
  • Time that should go toward closing deals and serving clients gets absorbed by repetitive marketing work.

What you need is a controlled way to reach the exact companies you want, create genuine interest, and bring suitable prospects into a sales conversation.

That is what Cold Sting is built to do.

Why Choose Cold Sting?

Cold Prospects Cannot Be Treated Like Warm Leads

Warm Leads

They already know you. They have existing trust and interest, making them ready for a pitch.

Cold Prospects

They didn't ask to hear from you. No prior trust. They ignore generic pitches and require a different approach.

Cold Sting uses the Cold Buyer Conversion System , a done-for-you acquisition system built around how cold prospects actually evaluate new opportunities. It has three pillars.

Pillar 1

Precision Targeting

  • Identify exact companies and decision-makers that match your ideal client profile.
  • Reach qualified buyers directly instead of relying on ads, content, or algorithms.

Avoid: Random visibility, unqualified audiences, and weak-fit opportunities.

Pillar 2

Inbox-First Infrastructure

  • Build and manage dedicated sending domains and inboxes for each campaign.
  • Protect deliverability through authentication, controlled volume, rotation, and monitoring.

Avoid: Spam placement, damaged reputation, and risk to your primary domain.

Pillar 3

Cold Buyer Psychology

  • Build campaigns around how unfamiliar prospects actually think, evaluate, and respond.
  • Move cold buyers from initial relevance to genuine interest without assuming they are ready to buy.

Avoid: Premature pitches, weak relevance, and treating cold prospects like inbound leads.

Most treat cold prospects as warm. We don't.

We build the entire campaign around the fact that they are not.

And that changes who we target, what we offer, how we introduce it, what proof we present, and what next step we ask them to take.

That is how the system moves someone from never having heard of your business to becoming a qualified sales appointment on your calendar.

Why we are different

Built differently, on purpose.

Most agencies optimise for their own margins. We optimise for your booked calls.

Your leads are yours alone

One client per niche, per geography. If we run cybersecurity in the US for you, we don't run it for anyone else.

Your brand stays premium

You approve every email before it sends. Sell a premium product, and the outreach reads like it.

Fully compliant B2B outreach

Verified business decision-makers only, never consumers. Every opt-out and unsubscribe honoured.

Private sending infrastructure

Your own domains, inboxes and IPs, never a shared pool with 100 other campaigns. Your main domain is never touched.

You stay out of the inbox

No warmups, no follow-ups, no reply triage. We handle it end-to-end until prospects show up on your calendar.

100% performance-based

No monthly retainer. You pay only when qualified calls land on your calendar.

What's possible

What cold outbound can do...in every B2B niche.

Done right, outbound produces the same outcome across wildly different markets: qualified meetings and real pipeline. A few examples of what others have achieved:

SaaS & Sales
62
meetings booked in 60 days
Claims recovery
100+
deals closed from outbound
Corporate wellness
40
sales-qualified leads in month one
Fleet tech
$11M
pipeline generated
A YouTube Content agency
10
meetings in 10 days
HR / screening
3
new enterprise clients in 30 days

As long as you sell to other businesses through sales meetings (calls), cold outreach will work for your niche too.

Welcome to Cold Sting.

Hi, I’m Dennis, founder of Cold Sting.
I founded Cold Sting with one mission: to make B2B prospecting more controlled, predictable, and effective.

Too many strong businesses can deliver great results and close the right buyers, but still rely on referrals, inconsistent inbound leads, or founders doing manual outreach. We built Cold Sting to solve that gap.

The goal is simple: create a consistent flow of qualified conversations while your team focuses on closing, delivery, and growth.

FAQ

You have questions. We have answers.

Do I need to provide the leads?
No. We handle research, sourcing, verification, and list-building to the ICP we agree on.
Will this put my main domain at risk?
No. We use separate sending infrastructure, so your primary business domain is never used for cold email.
What counts as a qualified appointment?
We define it together before launch: company type, size, location, title, authority, need, and clear interest.
How much of my time does this take?
Mostly onboarding. After launch, your job is attending the calls and giving us feedback from them.
Why shouldn’t I just hire an SDR?
An SDR means recruiting, salary, commission, software, and months of ramp, and zero if they quit. You get a whole outbound team and proven infrastructure for a fraction of the cost.
How quickly do campaigns launch?
After targeting, infrastructure, data, and messaging are ready. There’s a mandatory warm-up we never skip, and we give you a specific plan on the call.
What if I’ve already tried cold email?
A failed run doesn’t mean the channel is wrong. We diagnose targeting, data, infrastructure, offer, messaging, and follow-up before recommending you proceed.
How much does it cost?
The appointment fee depends on market, criteria, complexity, and volume. We calculate it with you on the call, not with a generic number.
What happens after the first month or two?
If it’s working, we move into ongoing management, optimizing, testing, and scaling. If targetsaren't hit, we refine and test until they are. You only pay for results.
