Cutting Growth Costs by 50% While Increasing Sales by 32% | Case Study

Discover the strategy, tactics and tools on how we reduced our client’s Cost of Growth by 50% and Increased Results by 32%

Growth is expensive—especially when it’s not optimised. Many companies pour money into sales and marketing without realising that smarter strategies can achieve better results for a fraction of the cost.

One of our clients was spending £16,000 per month on SDRs, marketing campaigns, and paid media but wasn’t seeing the level of results they needed.

Their cost per opportunity was too high, and their SDR team was drowning in manual tasks that didn’t drive revenue.

By implementing a strategic AI-powered sales and marketing workflow, we helped them:

✅ Reduce their cost of growth by 50%
✅ Increase deal creation and win ratios by 32%
✅ Streamline their outreach while improving email deliverability

This case study breaks down the exact strategies, tools, and workflows we used to transform their growth efficiency.

The Problem: Inefficient Growth Spend

Before working with us, the client had a cost-heavy sales and marketing model:

• SDR headcount was too high, with reps spending time on manual prospecting instead of selling.
• Paid media wasn’t yielding high enough ROI to justify ongoing investment.
• Email outreach lacked personalisation and engagement, leading to low response rates.

Their sales team was working hard but not smart, and their marketing budget wasn’t delivering enough opportunities to justify the spend.

Our Strategy: Smarter Growth Through AI and Automation

Instead of throwing more money at the problem, we focused on optimising efficiency using automation, AI-driven insights, and better outreach methods.

1. Optimising HubSpot for Smarter Workflows

The client already used HubSpot, but it wasn’t configured to drive efficiency. We redesigned their sales and marketing workflows to:

✅ Automate lead scoring and prioritisation
✅ Trigger follow-ups based on prospect behaviour
✅ Streamline SDR handovers to remove bottlenecks

This saved SDRs hours per week by eliminating unnecessary manual tasks.

2. AI-Powered Contact Research & Data Enrichment

We introduced Clay to power up their prospecting with automated workflows for:

✅ Enriching prospect data from multiple sources
✅ Auto-verifying emails and contact info
✅ Prioritising leads based on real-time insights

By removing manual research, SDRs could focus on selling, reducing the need for extra headcount.

3. High-Performing Email Copy with AI & Experience

Most outbound emails fail due to bad copy and weak CTAs. We fixed this by:

✅ Using Twain & Hemingway to refine email messaging for clarity and impact
✅ Leveraging our own expertise to improve email structure & CTA strength
✅ Creating compelling lead magnets to boost engagement via LinkedIn and email

This resulted in higher reply rates and stronger conversations, leading to more meetings booked.

4. Improved Email Deliverability & Infrastructure

Even the best email won’t work if it doesn’t land in the inbox. We implemented:

✅ Maildoso to improve email infrastructure & sender reputation
✅ Best-practice warm-up sequences to prevent spam filtering
✅ Instantly.ai for cold email automation at scale

As a result, their email deliverability skyrocketed, leading to 40% more responses from the same number of outbound emails.

5. Smarter Prospect Targeting with ICP & Persona Optimisation

We didn’t just spray and pray—we took a strategic approach to define:

✅ Tightly focused ICPs & personas to improve targeting
✅ Clear pain point-solution alignment to sharpen messaging
✅ The best channels for engagement, reducing wasted spend on underperforming outreach

This refinement alone led to a 20% improvement in meeting-to-close rates.

6. Better Contact Sourcing for More Precision

Instead of relying on SDRs manually sourcing leads, we used:

✅ Apollo.io to find accurate contact data
✅ LinkedIn Sales Navigator to refine targeting and identify warm leads

This approach increased outreach efficiency, reducing wasted effort and improving conversion rates.

The Results: 50% Lower Growth Costs, 32% Higher Results

By shifting away from manual-heavy SDR work and underperforming paid media, the client’s growth engine became significantly more efficient:

📉 Cost of growth reduced by 50%

• Fewer SDRs needed, saving thousands in salaries
• Reduced reliance on expensive paid media
• Improved efficiency from automation & AI

📈 Sales performance increased by 32%

• More deals created with better-qualified leads
• Higher reply & meeting rates from better email outreach
• Improved win ratios from clearer messaging & targeting

💡 Stat to Consider: Companies that implement AI-driven sales automation see a 20-30% increase in revenue while reducing operational costs (McKinsey).

Why This Approach Works for Any Growth-Focused Business

This transformation wasn’t just about cost-cutting—it was about working smarter, not harder. Here’s why this approach is effective for any sales & marketing team:

1️⃣ Less reliance on expensive SDR headcount – SDRs should sell, not research. Automating data collection reduces time spent on non-revenue-generating tasks.

2️⃣ Smarter, AI-powered outreach – Better messaging, better targeting, and better infrastructure all combine to improve results without spending more.

3️⃣ Stronger pipeline without increasing budget – By optimising lead sourcing and workflow automation, more deals get created from the same budget or less.

4️⃣ Better decision-making from data insights – A structured, automated approach reduces guesswork, ensuring every pound spent delivers impact.

Conclusion: Growth Without Wasted Spend

Scaling a business doesn’t have to mean spending more money on sales and marketing—it means spending smarter.

By leveraging AI, automation, and optimised outreach, our client:

✅ Cut their cost of growth by half
✅ Increased their results by 32%
✅ Built a leaner, smarter, more efficient growth engine

This growth model works for any business looking to scale while reducing unnecessary costs. If you’re currently overspending on sales and marketing, it’s time to rethink your strategy and embrace smarter growth.
