Sopro vs hiring an SDR team: Should you build in-house or choose a lead generation agency?
Summarise this article with:
If your business has reached the point where you need a more consistent flow of qualified sales opportunities, you’ll probably arrive at the same question many B2B leaders face:
Should we hire an SDR team or work with a lead generation agency?
Hiring sales development representatives (SDRs) gives you an in-house team dedicated to prospecting, outreach and booking meetings. But you’ll also need to invest in onboarding, training, management, prospect data, technology, deliverability and ongoing optimisation before your team reaches full productivity.
When you work with a specialist B2B lead generation agency (like Sopro), you gain access to experienced prospecting specialists, proven outreach strategies, high-quality data and the technology needed to generate qualified conversations, without recruiting or managing additional staff.
This guide compares both approaches, exploring the costs, benefits, and practical considerations of each, so you can decide which is the best fit for your business.

Which option is right for your business?
There’s no universal answer because every organisation has different objectives.
Some businesses want to build an internal outbound function that they’ll continue to grow over several years. Others need qualified conversations quickly but don’t have the time or resources to recruit and manage an SDR team.
Your decision should be guided by what you’re trying to achieve over the next 12 to 24 months.
A lead generation agency could be the right choice if…
You’ll probably benefit from working with a specialist partner if you’re looking to generate pipeline without creating an entire outbound sales function.
This approach often suits businesses that:
- Need qualified meetings within a shorter timeframe.
- Don’t have the capacity to recruit, train and manage SDRs.
- Want access to experienced prospecting specialists.
- Need reliable prospect data without maintaining it internally.
- Are expanding into new markets or launching a new product.
- Want predictable lead generation while allowing their sales team to focus on closing opportunities.
Instead of investing months in building the infrastructure for outbound sales, you can start generating conversations while your internal team concentrates on moving opportunities through the sales pipeline.

Hiring SDRs could be the right choice if…
Building an in-house SDR team can be an excellent long-term investment for organisations with the budget, leadership and resources to support it.
It may be the right approach if you:
- Plan to build a dedicated outbound sales department.
- Have experienced sales managers who can coach and develop SDRs.
- Already have the technology, data and processes needed to support prospecting.
- Expect to recruit multiple SDRs as your business grows.
- Want complete control over every stage of the outreach process.
While this route offers greater ownership, it also requires a significant commitment to recruitment, enablement and ongoing performance management.
Many businesses successfully combine both approaches
Many successful B2B organisations combine the two approaches. A lead generation agency can fill the top of the sales funnel by identifying target accounts, engaging decision-makers and booking qualified meetings, while internal SDRs focus on nurturing complex opportunities, following up on inbound enquiries or supporting strategic account-based campaigns.
This hybrid approach can be particularly effective for businesses experiencing rapid growth, entering new markets or testing new audiences before investing in additional headcount.
What does an SDR team actually do?
Sales development representatives play an important role in the B2B sales process.
Their primary objective is to identify potential customers, start conversations and qualify opportunities before passing them to account executives or sales managers.
On a typical day, an SDR might:
- Research target companies
- Identify decision-makers
- Build prospect lists
- Send personalised outreach emails
- Connect with prospects on LinkedIn
- Make outbound calls
- Qualify inbound enquiries
- Book meetings for the wider sales team
- Update CRM records and report on campaign performance
In many organisations, SDRs act as the bridge between marketing and sales, helping convert interest into qualified sales opportunities.
However, employing an SDR is only one part of building an effective outbound function.
To perform at their best, they’ll also need access to accurate prospect data, the right technology, clear messaging, ongoing coaching and a structured outreach strategy.
Without those foundations, even experienced SDRs can struggle to generate consistent results.
What is Sopro?
Sopro is a fully managed B2B lead generation agency that helps businesses generate qualified sales opportunities through targeted, multi-channel outreach.
Unlike hiring an SDR team, partnering with Sopro gives you access to the people, processes and technology needed to launch and optimise outbound campaigns without building everything internally.
Our managed service covers every stage of the prospecting process, including:
- Defining your ideal customer profile (ICP)
- Building highly targeted prospect lists
- Accessing a proprietary database of more than 15 million companies and 300 million prospects, refreshed weekly using custom web scraping
- Using AI-powered validation to remove up to 40% of unsuitable prospects before campaigns begin
- Writing and testing personalised outreach
- Managing email infrastructure, domain configuration and email deliverability
- Continuously refreshing audiences and optimising campaign performance
- Reporting on meetings, engagement and pipeline generation
Sopro uses intelligent features such as IP Match and Engage to identify anonymous website visitors, match them against your target accounts and trigger outreach based on genuine buying interest. This helps your sales team prioritise businesses already showing signs of intent.
With more than 25,000 campaigns delivered and 3,750+ businesses supported, Sopro combines specialist expertise, proprietary data and managed execution to help businesses build pipeline without the complexity of recruiting and running an internal SDR function.
Which option scales better as your business grows?
Both approaches can scale, but the right choice depends on how quickly you expect to grow and where you want to invest your resources.
Hiring your first SDR and building a team of five or ten SDRs are very different challenges.
As your outbound activity increases, so does the complexity of managing it. New hires need onboarding, prospecting lists become larger, outreach volumes increase and reporting becomes more sophisticated. Every additional team member also requires management, coaching and access to the right technology.
With a lead generation agency, you can increase campaign activity by refining your target audience, expanding into new markets or launching additional campaigns, without recruiting more people or expanding your internal infrastructure.
Hiring SDRs gives you greater control
You control recruitment, training, messaging, campaign priorities and performance management.
This level of control can be particularly valuable for businesses with complex sales cycles or highly specialised products, where SDRs benefit from extensive product training and close collaboration with account executives.
The trade-off is that growth often depends on recruiting additional people. If you want to double your outreach capacity, you’ll usually need to increase headcount and dedicate more management time to supporting the team.
A lead generation agency offers greater flexibility
Campaigns can be adapted as your objectives change, whether you’re launching a new service, entering a different market or targeting a new audience.
You don’t need to pause activity while recruiting or training additional team members, and you can scale outreach without significantly increasing your operational workload.
This flexibility can be particularly valuable for businesses that experience seasonal demand, rapid growth or frequent changes to their go-to-market strategy.

Data quality becomes even more important at scale
Maintaining data quality internally requires continuous effort. Records need to be refreshed, contact details verified and target accounts reviewed as businesses grow and decision-makers move roles.
Sopro manages this process as part of its service. Campaigns are powered by a proprietary database of more than 15 million companies and 300 million prospects, refreshed weekly using custom web scraping to keep company and contact information current.
AI-powered suitability matching also helps remove irrelevant prospects before outreach begins, allowing campaigns to focus on businesses that closely match your ideal customer profile.
Reaching prospects at the right time
Identifying the right companies is only part of prospecting. The timing of outreach also matters.
A company that wasn’t interested six months ago may be ready to buy today because it’s secured funding, expanded into new markets or hired new leadership.
Sopro’s approach goes beyond static prospect lists by continually cycling through target markets and identifying new opportunities as they emerge. Features such as IP Match and Engage also connect anonymous website visitors with your target account list, allowing businesses showing genuine buying intent to be prioritised for outreach.
Can you combine an SDR team with a lead generation agency?
Yes. Many successful B2B organisations use both services – a lead generation agency can help fill the top of the sales funnel by identifying target accounts, engaging decision-makers and booking qualified meetings. Meanwhile, internal SDRs can then focus on nurturing complex opportunities, following up inbound enquiries or supporting strategic account-based campaigns.
Sopro provides prospecting support for businesses with sales teams, allowing internal teams to concentrate on selling and closing.
Instead of spending hours researching prospects or maintaining databases, internal sales teams can dedicate more time to building relationships and progressing opportunities through the pipeline.
If your company has ambitious growth plans, combining external expertise with internal sales capability can provide the best of both worlds.

Which businesses benefit most from each approach?
By now, you’ve probably started to form a view on which option feels like the better fit. The decision often comes down to your available resources, growth objectives and the level of operational responsibility you’re prepared to take on.
Hiring an SDR team may be the right choice if you:
- Want to build a long-term outbound sales function.
- Have experienced sales leaders who can recruit, coach and develop SDRs.
- Already use the technology needed to support prospecting and outreach.
- Have the time and budget to invest in onboarding, training and ongoing development.
- Expect outbound sales to become a core capability within your organisation.
A lead generation agency may be the better option if you:
- Want to generate qualified conversations without recruiting additional staff.
- Need pipeline within weeks rather than months.
- Don’t have the internal capacity to manage prospecting, outreach and optimisation.
- Want access to high-quality prospect data and specialist expertise.
- Are expanding into new markets or testing new audiences.
- Prefer your sales team to focus on closing opportunities instead of building prospect lists.
Ultimately, the best approach is the one that helps your business generate sustainable pipeline while making the most effective use of your people, budget and time.

Expert Q&A: Choosing between an SDR team and a lead generation agency
What’s the difference between outsourced SDR services and a lead generation agency?
The terms are often used interchangeably, but they don’t always describe the same service.
An outsourced SDR provider typically supplies people to carry out prospecting activities on your behalf, such as researching prospects, sending outreach emails and booking meetings. In many cases, you’ll still be responsible for providing prospect data, messaging, sales tools and campaign strategy.
A lead generation agency usually delivers a broader managed service. This can include audience research, prospect data, campaign planning, outreach, deliverability management, reporting and ongoing optimisation, alongside appointment setting. If you’re looking for a partner to manage the end-to-end outbound process, a lead generation agency may be a better fit.
Is it better to hire an in-house SDR or work with a lead generation agency?
The right choice depends on your business goals and internal resources. Hiring an SDR can be a good investment if you’re building a long-term outbound sales function and have the time to recruit, train and manage a team. An in-house approach also gives you greater control over day-to-day activity.
A lead generation agency is often a better option for businesses that want to generate qualified conversations quickly without investing in recruitment, technology and ongoing campaign management. Many organisations also combine both models, using an agency to build pipeline while internal sales teams focus on qualifying and closing opportunities.
How do lead generation agencies charge for their services?
Some agencies charge a fixed monthly retainer for a fully managed service, while others operate on a performance basis, charging per meeting booked or qualified lead generated. There are also hybrid pricing models that combine a management fee with performance incentives.
When comparing providers, don’t focus on price alone. Consider what’s included in the service, such as prospect data, campaign management, reporting, deliverability support and account management, as these can have a significant impact on overall value.
For a clearer idea of what a fully managed service costs, see our pricing.
Is a lead generation agency more cost-effective than hiring an SDR?
It can be, particularly when you consider the wider costs involved in building an internal outbound function.
Hiring an SDR usually involves recruitment costs, salary, employee benefits, onboarding, training, management time and investment in prospect data and sales technology. Those costs continue beyond the initial hire and often increase as your team grows.
A lead generation agency typically bundles many of these elements into a single service, making costs easier to predict while reducing the operational burden on your internal team.
Are performance-based lead generation agencies better?
Performance-based pricing can be attractive because it appears to reduce risk, but it’s worth understanding how success is measured.
Some agencies focus on the volume of meetings booked, while others prioritise lead quality or opportunities generated. If performance is measured purely by quantity, there’s a risk that meeting quality becomes secondary.
Before choosing a provider, ask how they define a qualified meeting, how they measure campaign success and what happens if results don’t meet expectations. A transparent reporting process and shared definition of success are often more valuable than the pricing model itself.
What’s the difference between appointment setting and lead generation?
Lead generation is the broader process of identifying, engaging and nurturing potential customers until they’re ready to speak with your sales team.
Appointment setting services form one part of that process, focusing specifically on arranging meetings between qualified prospects and your sales team.
Many lead generation agencies provide appointment setting as part of a wider service, alongside audience building, prospect research, outreach, reporting and campaign optimisation.

How should you evaluate an SDR outsourcing company?
Choosing the right partner involves more than comparing prices. Ask the following questions to understand how the provider works and what that could mean for your business:
- How do you build and verify prospect data?
- How do you define a qualified meeting?
- What industries do you specialise in?
- How do you personalise outreach?
- What reporting will I receive?
- How do you manage email deliverability?
- What results have you achieved for businesses like mine?
- Who will manage my account?
The answers should give you confidence that the provider understands your market and has a structured process for generating high-quality opportunities.
Should I choose a cold calling agency or an email-led lead generation agency?
The best approach depends on your audience, product and sales cycle.
Cold calling can work well for time-sensitive opportunities or industries where direct conversations are expected. Email outreach is often more scalable and gives prospects the opportunity to engage in their own time.
Many successful lead generation campaigns combine email, LinkedIn and phone outreach, giving prospects more ways to engage and respond.
Sopro’s multi-channel marketing service coordinates email, LinkedIn and phone outreach to reach the right prospects more effectively.
Is an SDR agency the right choice for enterprise businesses?
Some enterprise businesses build internal SDR teams to support strategic account development, while others partner with specialist agencies to accelerate pipeline generation, enter new markets or supplement existing sales capacity.
For many enterprise organisations, a hybrid approach provides the greatest flexibility, combining internal expertise with external prospecting support where additional capacity or specialist knowledge is needed.

What are the pros and cons of an SDR agency versus a lead generation agency?
An SDR outsourcing provider can be a good choice if you’re looking to extend your internal sales team and already have the strategy, technology and management processes in place.
A lead generation agency typically offers a broader managed service, taking responsibility for prospect research, data quality, outreach execution, campaign optimisation and reporting.
If your objective is simply to increase prospecting capacity, outsourced SDR services may be sufficient. If you’re looking for a partner to manage your outbound lead generation from strategy through to qualified meetings, a lead generation agency is often the more comprehensive solution.
