Outsourced SDRs (+AI): The Secret to Growing Your Sales Team in 2025

The growing trend of dynamic sales journeys, coupled with unprecedented competition, has resulted in businesses across industries increasingly struggling to get potential buyers through the door. 

The core principles of sales have remained the same, but the operational strategies and execution tools have evolved, and it’s crucial to keep up with these shifts. 

One of the biggest hurdles for modern sales teams is efficiently managing their time. For reference, on average, over 70% of sales reps’ time is allocated to non-revenue-generating, non-customer-facing activities, mostly on prospecting and research. 

So the question arises: What if your sales professionals could channel all their time and resources into what they do best and what matters most—engaging interested, ready-to-purchase prospects, hosting demos and meetings, and closing deals? 

Well, with the recent boom of reputable agencies providing outsourced SDR services and AI tech, this is easier (and cheaper!) to achieve than you may think! 

In this article, we’ll explore how to build a fully functioning outsourced sales team with external and AI sales agents, and how to merge them with your in-house sales team for a cohesive and efficient sales force. 

What is an outsourced SDR team?

First things first, let’s remove all the blurred lines between an in-house and outsourced sales team. In-house sales reps are hired by a company internally through the traditional and lengthy process of finding suitable talents, onboarding, and training them.

Outsourced SDRs are external professionals, often provided by dedicated outsourcing companies or agencies, who have the necessary training and expertise to handle the early stages of a company’s sales cycle. They primarily focus on prospecting, qualifying leads, and nurturing them until they are ready to potentially make a purchase, at which point they are handed over to the internal sales team for closure. 

Outsourced SDR teams are not company employees but rather an extension of your business, offering expertise and scalability without the need for hiring, onboarding, training, and management. 

Partnering with an outsourced sales agency typically follows the following steps: 

1. Defining your business’s ideal customer profile (ICP), target markets, product/service functionality, and value proposition for outsourced sales reps to effectively carry out their responsibilities. 
2. Outsourced sales reps will dive deep into identifying targeted leads that match your ICP and then research relevant prospect/company data to compile detailed prospect lists for further outreach.   
3. Outsourced sales reps will then create comprehensive outreach campaigns, often leveraging their agency’s sales tools like Reply.io, using proven strategies and the most appropriate channels including email, phone, or social media to engage prospects.
4. Once prospects respond to their initial outreach touchpoints, outsourced SDRs will qualify them based on pre-defined criteria and hand them off to in-house teams, ensuring only high-potential leads reach those final stages of the sales cycle. 

Outsourced SDR teams will be highly effective in 2025 due to the flexibility and scalability they offer businesses, empowering them to grow operations without the costly long-term commitments regarding hiring full-time employees. 

Sales professionals’ turnover rates have been steadily increasing, so this gives companies one less headache in the long run. Besides, for many years now businesses have mastered how to manage remote sales teams.

Outsourced AI sales agents

Outsourced sales professionals have existed for quite some time now, but AI sales agents are a brand-new addition to the world of sales. AI-powered SDRs are now a reality, fully capable of effectively carrying out the initial stages of the sales cycle that modern sales reps spend so much of their valuable time on.

AI sales agents are built on revolutionary technology, equipped with advanced algorithms to handle complex tasks and natural language processing (NLP) capabilities to interpret human language, as well as think and communicate just like a human would.

AI SDR agents like Jason AI are being increasingly incorporated into modern sales teams as part of their outsourced workforce. They are seamlessly integrated, easily trained, and perfect at carrying out early-stage sales processes including:    

• Building targeted prospect lists based on your company ICP and past/existing buyers; 
• Researching prospects and collecting relevant data about their companies and roles; 
• Generating hyper-personalized outreach messages tailored to each prospect, at scale; 
• Engaging in conversational interactions with prospects and handling objections;  
• Scheduling meetings or calls for the in-house, human sales representatives.

The rise of AI SDRs in 2025

AI SDRs are recently gaining more and more traction as companies and end-users become more aware of this technology. They seamlessly integrate into existing tool stacks including CRMs, sales and marketing software, and lead databases, to name a few, and once trained—become full new members of your sales team. That’s right, the future is here! 

Speaking of, AI SDRs only need to be trained at the very beginning by explaining your product, ICP, target market, main value proposition(s), main use cases, and so on. Then, thanks to their machine learning capabilities, these AI agents will ‘learn on the job’, analyzing which prospects convert best to alter their targeting activities, analyzing which messages work best and why to alter their outreach strategy, and so on.

The value that AI SDRs bring to a sales team is unparalleled: 

Cost-effectiveness → AI SDR subscription costs are significantly cheaper than human SDR salaries, which are $80,000/year on average according to Glassdoor, and that’s without taking into account the onboarding and training costs. AI SDRs are much cheaper to implement and operate for those looking to grow their agency or business;

• Efficiency and scalability → AI SDRs handle repetitive tasks like prospecting, lead qualification, cold outreach, follow-ups, etc., at a volume and speed that no human SDR could ever match, by no fault of their own. AI works 24/7, with no breaks, and can simultaneously generate hundreds of hyper-personalized effective cold emails at a time; 
• Data-driven personalization → AI sales agents leverage prospect data to personalize outreach at lightning speed, without the hassle of manually going through customer or LinkedIn profiles. For example, Jason AI gathers data from previous interactions, CRMs, and LinkedIn profiles to craft tailored messaging that feels personal and humanized;

• Consistency → AI SDRs don’t take days off, they don’t take breaks, and they don’t sleep, so your sales team will be working round the clock. They will also never forget to follow up, lose track of a conversation, or make any typos, producing consistent and reliable results every time.

Benefits of an outsourced SDR solution (human + AI) 

Once outsourced SDRs and AI-powered sales agents are combined, businesses can significantly ramp up their sales operations and expect a better pipeline in the long run. 

While outsourced human and AI SDRs will be taking care of the early and middle stages of the sales cycle, in-house sales teams will be working their magic on the qualified, purchase-ready leads. 

Here’s how this fusion of outsourced sales professionals and AI SDRs is a game-changer:

Cost savings

Outsourcing early-stage SDR functions like prospecting and initial cold outreach allows businesses to significantly cut down on their operational costs. For starters, companies enjoy a much lower overhead since they are no longer required to spend on salaries, benefits, sales tools, and office spaces for in-house SDRs.

AI SDRs further reduce the need for additional hires as they can scale their operations for a marginal increase in subscription price when compared to adding a new in-house sales rep. 

Last but not least, both outsourced SDRs and AI SDRs most often work on a fixed fee/pricing, which empowers businesses to more effectively optimize, monitor, and forecast their budgets. 

An outsourced SDR solution helps businesses allocate their finances more effectively, while the money saved on outsourced sales solutions instead goes into other strategic initiatives like marketing campaigns, product development, retention, etc. 

Time efficiency

Something no less important for businesses than lowering costs is being efficient with their time, and outsourced SDR teams and AI agents ensure it’s used wisely. 

Finding potential customers, researching relevant data about them and their companies, and then utilizing that data to create meaningful, personalized outreach takes a whole lot of time and effort, now put that in the context of hundreds or thousands of prospects. 

AI SDRs work around the clock to make outsourced sales reps’ lives easier, constantly sourcing and organizing all that data to be used, and ensuring that no opportunity goes unattended.  

Enhanced productivity

Besides outsourced sales forces taking over the tedious, time-consuming processes we’ve discussed, it’s also worth noting that the time freed up for in-house sales reps will instead be leveraged for the more complex, high-value activities, which is another, no less important way to drive productivity and overall revenue growth.

These high-value activities include engaging on a more personal level with key decision makers, building stronger relationships with potential and existing buyers and partners, attending meetings, optimizing the overall sales strategy, and ultimately closing deals. 

Improved lead quality

All this talk about efficiency and productivity, but what about the actual quality? Even though in business ‘faster’ doesn’t always mean ‘better’, in the context of outsourced sales teams—you really do get the best of both worlds. 

The combination of human expertise and AI capabilities results in superior lead sourcing, nurturing, and qualifying, which ultimately results in better overall lead quality when they reach the final stages of their buyer journeys.

For starters, increased competition is one of the main challenges agencies face in 2025, which is why you can rest assured that they’re only hiring the top sales experts out there. They will handle your sales prospecting and engagement no worse than your in-house teams. 

On top of that, AI SDRs dig deep in their data analysis to identify high-potential prospects based on behavioral patterns, industry trends, and firmographics, and then craft tailored hyper-personalized messages designed to spark higher response rates. 

Faster scaling

While having your own in-house sales team has its own benefits, once it’s established and successful and the time comes to scale operations, this is where outsourcing your new sales force makes a lot more sense. 

Outsourced SDRs provide the financial and structural flexibility to grow operations without spending too much time or getting into any long-term commitments like one would with hiring new sales reps. 

At the same time, AI SDRs like Jason AI can now take over all of the prospecting tasks with ease, and whether it’s researching and engaging 100 or 1,000 prospects at a time—these AI sales machines see virtually no difference. 

Building your ultimate sales team

Now that we’ve covered everything, it’s time to put all the pieces of the puzzle together and go over the step-by-step process of building your ultimate sales team, leveraging the unique value and expertise of both your in-house and outsourced sales professionals.

Building your outsourced sales force in 2025  

In 2025, building a powerful sales team is not about choosing between human expertise and AI, in-house or outsourced—it’s about combining all these elements and strategically allocating them to the right sales processes for maximum efficiency. 

SDR outsourced services offer flexibility and expertise, AI SDRs offer data-driven efficiency and scalability, and in-house sales reps offer in-depth product and company knowledge to sway key decision-makers. 

This hybrid model may take some time to set up and run, but once done, businesses can expect much better productivity and results, exactly what modern businesses are striving for in our hyper-competitive landscape.
