Proactive Outbound Sales Development Teams

B2B leaders come to us because their inbound channels aren’t enough, their sales teams are stretched too thin, or their current outbound efforts aren’t working. Whether it’s launching into new territories, breaking into key accounts, or strengthening your Go-To-Market engine, our SDR teams deliver consistent, qualified opportunities that convert into long-term customers.

We identify and engage your ideal customer profile (ICP) using validated data and a value-first approach. AI signals enable personalised, sequenced outreach across phone, email, and social, so our SDRs can create a qualified pipeline at scale.

For high-value target accounts, we use account-based sales development (ABSD). Our SDRs map accounts stakeholders, identify buying signals, uncover pain points, and execute tailored engagement strategies that open doors and build momentum.

Launching something new? We help you quickly identify early adopters, validate messaging, and build a pipeline for new offerings.

Expanding into a new geography or vertical? Our sales development reps conduct deep account research and engage target buyers to establish your foothold in new markets.

Events provide high-intent moments to capture attention. Our SDRs boost registrations pre-event and follow up post-event to convert interest into SQLs. Throughout this process, we gather valuable insights on buyer challenges, objections, and engagement signals to help you refine positioning and close more deals.

Inbound lead flow drying up or not getting you there fast enough? New product launch? Struggling to get outbound to work?

Let us be laser-focused on who you want to target that fits your ideal customer profile.

We use the latest technology and validated data points to clarify what drives pipeline. Our SDRs will take a “value-first” approach to messaging, while nurturing prospects with sequenced outreach across multiple channels.

You may have many leads still at MQL stage that you struggle to convert. Our SDRs swiftly engage MQLs, nurturing and qualifying them to a point they are ready for the sales team.

They personalise their approach based on lead interests, gather essential information about their challenges, needs and budget, and implement nurturing strategies for leads not yet sales ready.

We also provide valuable insights to both marketing and sales teams about lead quality and common objections.

You might have a large account base of customers with a “long tail” that you are struggling to serve correctly. These customers could be on systems or solutions reaching at the end of life, making them prime targets for your competition.

Our SDR teams can engage and nurture these customers maintaining your install base, nurturing and upselling to them.

You may have key target accounts who are your ideal customers. Our SDRs conduct in-depth account research, understanding their structure, map out and engage key decision-makers, and potential pain points. 

They craft personalised outreach strategies that cut through the noise to engage multiple stakeholders.

SDRs can be effectively utilised for both pre-event and post-event activities to maximise event ROI.

Pre-Event

From targeted outreach to promote event and boost registrations. Through to appointment setting and personalised invitations for key prospects.

Post-Event

This is most crucial and where many brands fail. Our SDRs schedule follow-up meetings with qualified leads, while implementing nurturing strategies for not-ready leads.

Throughout this process, our SDRs gather valuable account intelligence to feed back to you, such as engagement levels and buying signals.


Every acquisition campaign starts with alignment. We integrate closely with your sales and marketing teams to define ICPs, validate data, and refine messaging, including a Sales Audit & Diagnostic if it suits.

Our ‘Selling at a Higher Level’ methodology ensures every interaction delivers value, while continuous feedback loops improve conversion quality.

Net new customer acquisition services are about generating qualified opportunities for your sales team. At durhamlane, this means acting as your outsourced sales development function: combining outbound prospecting and inbound lead conversion to identify and nurture the right decision-makers. We build the pipeline and deliver sales-ready conversations, so your in-house team can focus on winning new customers.

Outsourcing puts a ready-made sales development engine at your fingertips in the form of experienced SDRs, proven playbooks, and the tech stack to match. It removes the cost and risk of hiring in-house, while giving you momentum from day one.

Lead generation often focuses on data collection, i.e. a prospect’s email address. It doesn’t indicate a level of intent or likelihood to become a customer. On the other hand, customer acquisition services are proactive: SDRs directly engage decision-makers, qualify intent, and create sales-ready opportunities.

Typically, B2B organisations tackling complex sales cycles and ambitious growth targets see the greatest impact from customer acquisition services. If your team is stretched thin or entering new markets, we bring the capacity and expertise to generate high-quality opportunities. The result is a stronger pipeline built for sustainable growth.

Every organisation is different, and results depend on factors such as the complexity of your sales cycle, the markets you’re targeting, and the maturity of your current sales process. What we can say is that our approach is designed to deliver both quick wins and sustainable long-term pipeline growth. Generally speaking, 6 months should be given to prove the concept, leading metrics and initial results will be seen from month 1.
