SDR B2B lead generation compared: Delta-v vs Air Marketing

Outsourcing your SDR function should accelerate your growth, not stall it. But the wrong partner brings inconsistent qualifications, poor visibility, and a flat pipeline.

We compare Delta-v and Air Marketing to help avoid outcomes that directly impact results. These include expertise, scalability, pricing structure, tech stack integration, quality control and more. Ultimately, you will compare and choose the best fit for your business.

Regions covered & localisation

Delta-v regions covered & localisation

Delta-v covers the United Kingdom, Ireland, the Nordics, DACH, Benelux, the Middle East, and South Africa.

Air Marketing regions covered & localisation

Air Marketing is a UK-based provider. Their focus is on UK-based B2B outsourced sales, lead generation, and support for national campaigns. They position their localisation as market-specific adaptation, with messaging tailored by territory.

Key takeaway

If you are planning an expansion or operate across multiple regions simultaneously, Delta-v is better aligned, especially for targeted campaigns covering EMEA. If you want an agency that focuses on the UK alone, Air Marketing is the better fit. However, if you want an SDR agency that can target multiple regions, opt for Delta-v.

Industry expertise

Delta-v industry expertise

Delta-v has deep domain knowledge in Enterprise Software and FinTech sales in the EMEA region, with a focus on turning complex B2B offerings into qualified meetings and sales pipeline.

Air Marketing industry expertise

Air Marketing positions its industry expertise around breadth and repeatability in multi-sector B2B outreach, rather than deep knowledge in a specific area. They present the capability of working for companies across SaaS and IT, finance, energy and EV fleet, manufacturing, healthcare, and logistics, supported by case studies and recognisable client names that signal credibility.

Key takeaway

If you are selling complex FinTech or Enterprise software, a generalist approach won’t be sufficient. You need Delta-v’s purpose-built expertise to navigate the nuance and secure qualified meetings with hard-to-reach decision-makers.

If you are in an industry like manufacturing, logistics, or healthcare, Air Marketing offers the broad experience to handle generic outbound campaigns.

Talent model

Delta-v talent model

Delta-v utilises SDR teams that embed into your organisation and focus exclusively on your success. SDRs are supported by a Dedicated SDR Manager, Account Manager, Campaign Strategist, and Sales Operations Analyst. Delta-v only hires A-team talent who work in-office at Delta-v’s HQ, and it has its own Go-to-Market Academy to ensure consistency in training and output from its SDRs.

Air Marketing talent model

Air Marketing’s talent model is positioned as an outsourced SDR unit, framed as a complete SDR function with wrap-around support. They claim to provide a managed SDR team and the support system around it, so the delivery doesn’t rely on a single individual.

Recruitment is described as rigorous, prioritising values with ongoing development through their Air Sales Academy.

Key takeaway

Both agencies deliver a fully supported, outsourced SDR function. The deciding factor is the complexity of your sales process.

If you are selling FinTech or Enterprise software, generalist teams struggle. You need Delta-v’s purpose-built model.

Onboarding speed

Delta-v onboarding speed

Delta-v commits to a 30-day launch, including comprehensive onboarding: building a sales playbook, setting up the tech stack, and creating the training for dedicated SDR resources. They provide a fully functional, dedicated SDR team that will be live within a month, with a fixed monthly fee covering technology, infrastructure, personnel, and management.

Air Marketing onboarding speed

Air Marketing prioritises rapid deployment, though they do not publicly commit to specific launch timelines. Their model focuses on minimising ramp time, getting campaigns live quickly, and iterating on the fly to generate early activity.

Key takeaway

Air Marketing prioritises speed. If you need rapid mobilisation and are willing to iterate on the fly, their lighter approach can work for certain industries. But high-ticket sales require structure. You need a clear commitment and a well-developed playbook to navigate the complexity of enterprise deals. Delta-v is superior in its onboarding speed and the quality of its outbound campaign at launch.

Performance results

Delta-v performance results

Delta-v demonstrates impact measured in pipeline value and senior stakeholder access. One programme generated more than $5M in unweighted pipeline value within six months.

While another client saw the initial three-month ramp reach 250% of benchmark targets, including a month in which a single SDR booked 23 meetings, other performance metrics include 95 qualified meetings booked in 6 months, surpassing the 90-meeting benchmark.

Air Marketing performance results

Air Marketing highlights broad outcomes across the pipeline and ROI, citing examples like £28m in projected pipeline for Johnson Controls.

However, their case studies blend multiple marketing and sales channels. Because they do not isolate the SDR function, it is unclear how much of that pipeline actually came from targeted outbound versus other marketing efforts.

Key takeaway

Air Marketing’s cross-industry, multi-channel case studies make it impossible to verify their SDR-specific results. If you want blended marketing metrics, their broad approach works.

Complex FinTech and Enterprise sales require SDRs who actually know your industry. Delta-v offers a better solution for targeted campaigns across the EMEA region. This is backed by Delta-v’s case studies.

Reporting & transparency

Delta-v reporting & transparency

Delta-v’s visibility is a core promise. They offer full system access, weekly meetings, and granular reporting to give you complete visibility into SDR efforts. Case study evidence backs their claims of reporting success and transparency.

Air Marketing reporting & transparency

Air Marketing positions reporting and transparency as core to its delivery. They offer regular reports from a dedicated account management team, with an emphasis on live dashboards and clear KPIs.

Key takeaway

Both agencies deliver dashboards, clear KPIs, and regular check-ins. You will get baseline visibility either way. Your decision should therefore be based on the industry expertise required for your specific business.

Scalability & flexibility

Delta-v scalability & flexibility

Delta-v offers a fully operational, dedicated SDR team in 30 days. For flexibility, Delta-v allows customers to scale capacity up or down as needs evolve. Clients reference the flexibility to expand into new markets without the delay and overhead of building an in-house team.

Air Marketing scalability & flexibility

Air Marketing positions scalability and flexibility as core advantages of outsourcing, framing its model as one that can scale activity up or down on demand, including during campaign changes and seasonal peaks, without long-term fixed costs.

Key takeaway

Here, you need to consider whether your business requires steady, long-term outbound capacity or short-notice flexibility that scales with demand. If your business needs a long-term, consistent outbound engine that can expand into new markets, Delta-v offers a stronger solution. If the business needs rapid capacity changes and operational flexibility, Air Marketing’s model may be the better fit.

Pricing model

Delta-v pricing model

SDR-team-as-a-Service pricing includes an onboarding & setup fee, a monthly retainer per SDR, plus a fee per Sales Accepted Lead. Both of Delta-v’s Enterprise SDR-team-as-a-Service and standard SDR-team-as-a-Service pricing are available on request.

Air Marketing pricing model

Air Marketing uses a quote-based pricing model rather than published fixed rates, prompting prospects to reach out to discuss pricing.

Key takeaway

Both offer quote-based pricing, with Delta-v slightly clearer in terms of how the quote is made up. However, pricing shouldn’t be the deciding factor; the quality of the leads should, and here it comes down to industry experience. For FinTech and Enterprise, Delta-v excels. For broader campaigns, Air Marketing is a good option.

Tech stack & integration

Delta-v tech stack & integration

Delta-v utilises LinkedIn Sales Navigator, B2B data providers, and a sales engagement platform. For each new customer, they set up a dedicated Salesloft instance.

Air Marketing tech stack & integration

Air Marketing’s SDR tech stack is HubSpot-centric, with delivery described as integrating SDR activity directly into the client’s HubSpot. Their sales motion is presented as multi-channel, centred on email, calling, and LinkedIn social selling.

Key takeaway

In practical terms, Delta-v offers a standardised, best-in-class outbound engine that the provider controls end-to-end. Air Marketing prioritises visibility and seamless alignment within HubSpot with minimal stack disruption, and is easy to get up and running.

Training & quality control

Delta-v training & quality control

Delta-v runs a formal sales training programme, the Go-to-Market Academy, with clear progression. Quality is reinforced by close trainer support, ongoing coaching from sales leaders, a continuous learning environment, weekly reporting and monthly campaign strategy sessions, with leadership readiness within 12-24 months.

Air Marketing training & quality control

Air Marketing anchors their training in the Air Sales Academy to deliver live, interactive training across core SDR skills. Training is framed as a continuous development model with regular weekly sessions and accountability. Their SDRS go live in week 1, with controlled call exposure.

Key takeaway

Putting an SDR on the phone in week one to learn on the job burns your target accounts. Air Marketing’s iterative training model works for simple B2B, but it fails in high-ticket sales.

Selling complex FinTech and Enterprise software requires deep domain expertise. Delta-v’s Go-to-Market Academy produces SDRs who actually understand your market.

Conclusion

Delta-v and Air Marketing are both credible SDR partners, but each offers a solution tailored to a different type of business. Delta-v offers better targeting across EMEA and high-ticket sales for FinTechs and Enterprises. Air Marketing offers speed, flexibility, and a managed service that scales across multiple industries.
