We Book the Sales Calls. You Only Pay When They Happen.
Every prospect is researched across multiple sources, verified against your ICP, and showing a live reason to buy before we send a single email. You take the calls. We take the risk.
Qualified means a decision-maker at a company matching the ICP we agree in week one, who attends the call.
A call that never happens never reaches your invoice.
For the 60-day pilot, the monthly deposit is credited in full against your first qualified calls. After that it covers the cost of running your outbound.
No retainer, no setup fee, no lock-in. We re-earn the next month every month.

How to Consistently Win More High-Paying Clients Each Month Through Running Tightly-Listed & Trigger-Based Cold Email Campaigns
Outbound, Engineered.
Every channel, every touchpoint, every message is intentional. We build systems that generate pipeline, not just activity.
ICP Research & Targeting
We build hyper-specific ideal customer profiles down to firmographic, technographic, and behavioural signals. We know the difference between “companies with 50–200 employees” and “Series B SaaS companies actively hiring SDRs who just switched CRMs.”
Cold Email: Our Core Speciality
Cold email is the channel we've engineered from the ground up. Our Qualification Engine means every email is sent to a verified, ICP-matched prospect with a research-based reason-to-reach-out, not a generic template. For clients who want to go further, we can layer in LinkedIn outreach and cold calling on top.
Research-Backed Personalisation
Every personalised line we send is graded by strength and traceable to the specific signal that produced it: a job posting, a leadership change, a client win, a founder's own words. Because we tune the research logic to your ICP, your offer, and your tone, every lead comes with a reason-to-reach-out that's actually specific to that person, not a mail-merged "I saw you work at {{company}}".
Deliverability & Infrastructure
Domain warming, inbox rotation, SPF/DKIM/DMARC, volume ramps, and inbox placement monitoring. If your emails land in spam, nothing else matters.
Data & Enrichment
Multiple data sources, cross-referenced and triple-verified. We keep bounce rates under 2% because clean data is the foundation of everything.
Transparent Reporting
Reply rates, positive replies, and meetings booked, broken down by segment, angle, and channel. We deliberately don't track opens: tracking pixels damage deliverability, and opens don't close deals. Outbound is an iterative experiment, not set-and-forget.
Our Process
From zero to a booked calendar: a repeatable, transparent system built around your specific market.
ICP Definition & Qualification Engine Training
We work closely with you to define your ideal customer profile down to firmographic, technographic, and behavioural signals. We then train the Qualification Engine specifically on your ICP and offer.
Lead List Building & Verification
We scrape leads matching your ICP across multiple data sources, cross-reference them, and double-verify every email address before anything enters the Qualification Engine. Clean data is non-negotiable.
AI Qualification & Deep Research
The Qualification Engine researches each prospect across multiple sources, detects trigger events relevant to your offer, and qualifies or disqualifies them against your ICP. Only genuinely qualified leads move forward.
Infrastructure Setup & Outreach
Dedicated sending domains, expert DNS config, inbox warm-up, and daily health monitoring, so emails always land in the primary inbox. We then run personalised, research-based outreach to every qualified prospect.
Inbox Management & Handoffs
We handle all replies and back-and-forth with interested leads, book them directly onto your calendar, and provide full context on each prospect. You just show up and close.
Not Your Typical Lead Gen Shop
Most agencies measure success by activity. We measure it by revenue impact, and we're built top to bottom to deliver that.
Sales-Aware Handoffs
We don't just toss a “meeting booked” notification. We provide prospect context, what resonated, and can join early calls to ensure a warm transition.
Willingness to Disqualify
If your offer, pricing, or positioning is the bottleneck, we'll tell you. We're a strategic partner, not a volume vendor; your success is our success.
Compliance Built In
GDPR, CAN-SPAM, and evolving regulations. We stay on top of it so you never face legal or reputational risk from your outbound activity.
Quality Over Quantity
We use strict qualification criteria to deliver real sales-qualified leads. Vanity metrics look good in a deck; booked meetings that close look good on a P&L.
The Things People Ask.
Pricing, qualification, compliance, and what you are actually signing up for. Straight answers, no discovery call required.
How much does Perihelion Growth cost?
You pay a £500 monthly deposit. During the 60-day pilot it is credited in full against your first qualified calls, so those calls arrive already paid for. After the pilot, the £500 goes towards the cost of running your outbound instead of being credited to calls. Beyond the deposit you pay per qualified call held. There is no retainer, no setup fee, and no lock-in: the arrangement is monthly rolling, so we re-earn the next month every month.
What counts as a qualified call?
A qualified call is one with a decision-maker at a company matching the ICP we agree in week one, who actually attends the call. A call that never happens never reaches your invoice.
How is pay-per-call different from a retainer lead generation agency?
A retainer agency is paid for activity whether or not that activity produces meetings, which puts the risk on you. We are paid for qualified calls that are held, which puts the risk on us. You take the calls, we take the risk.
What is the Qualification Engine?
The Qualification Engine is the research and personalisation system behind every campaign. We train it on your ICP and your offer, then it researches each prospect across multiple data sources, verifies they genuinely fit that ICP, checks for live trigger events, and produces research-based messaging for each prospect that makes the cut. Every prospect gets an explicit verdict with a written reason, so disqualifications can be reviewed and used to sharpen the ICP.
Which outbound channels do you use?
Cold email is our core speciality and the channel we have engineered from the ground up. For clients who want to go further, we can layer LinkedIn outreach and cold calling on top.
Who do you work with?
B2B small and medium-sized businesses selling to other businesses, in the United Kingdom and the United States. We define the ideal customer profile with you in week one, down to firmographic, technographic, and behavioural signals.
Is your outbound GDPR compliant?
Yes. Compliance with GDPR, CAN-SPAM, and evolving regulations is built into how we run campaigns, so you do not face legal or reputational risk from your outbound activity.
Do you track email opens?
No, deliberately. Tracking pixels damage deliverability, and opens do not close deals. We report on reply rates, positive replies, and meetings booked, broken down by segment, angle, and channel.
Is the work outsourced?
No. Every campaign is founder-led and never farmed out. We also handle all replies and the back-and-forth with interested leads, book them directly onto your calendar, and hand over full context on each prospect.
What results do you see?
Across the live outbound campaigns we run, bounce rates stay under 2%, reply rates run above 3%, and above 40% of those replies are positive. We keep bounce rates low by cross-referencing multiple data sources and double-verifying every email address before it enters the Qualification Engine.

How the money works
- You pay per qualified call held. No call, no invoice.
- A £500 monthly deposit gets the campaign live. During the 60-day pilot it is credited in full against your first qualified calls, so you are not invoiced for those calls, the deposit has already covered them. After the pilot, the £500 goes towards the cost of running your outbound.
- Lead sourcing, data verification, AI research credits, mailboxes, and sending infrastructure are all included. No retainer, no setup fee, monthly rolling.
Fifteen minutes, no pitch deck. We will tell you straight whether your ICP is one we can reach.
Qualified means a decision-maker at a company matching the ICP we agree in week one, who attends the call.
