Sales development as a function and a career
Sales development is the pipeline-generation process that bridges marketing and sales. It encompasses the roles, processes, and strategies focused on identifying, contacting, and qualifying potential customers before passing them to account executives for closing. Done well, it is one of the highest-leverage functions in a B2B sales organization.
At ZoomInfo, the all-in-one AI GTM Platform, we invest heavily in developing SDR talent from within. Brian Vital, Vice President of Sales Development at ZoomInfo, has built a sales development program designed to take SDRs from diverse backgrounds and ramp them to full productivity within a year. This article covers what that program looks like in practice, and what sales leaders can take from it to build their own.
Whether you are an aspiring SDR figuring out what the role actually entails, or a sales leader building a development program from scratch, the career path and coaching philosophy that follow are worth understanding. For a related perspective on how ZoomInfo develops women in B2B sales, that piece covers the same culture from a different angle.
What sales development actually means
Sales development is the set of processes, roles, and strategies focused on identifying, contacting, and qualifying potential customers before passing them to account executives. The function owns top-of-funnel pipeline generation. AEs own closing. Those two responsibilities are distinct, and conflating them is one of the most common structural mistakes growing sales organizations make.
A sales development representative works the front end of the revenue process: researching target accounts, reaching out via phone and email, qualifying interest against defined criteria, and booking meetings for account executives. The SDR does not close deals. The AE does not cold-prospect at scale. Each role is optimized for a different stage of the buyer journey.
The traditional perception of SDR as an entry-level placeholder is shifting. Modern SDR roles require a specialized skill set: CRM proficiency, prospecting methodology, objection handling, and increasingly multi-threading across buying committees. High-performing teams treat SDRs as top-of-funnel experts, not as a holding pattern before a "real" sales role. That reframe changes how you hire, train, and develop the function.
There is also an important structural distinction between inbound and outbound SDRs. Inbound SDRs handle marketing-generated leads, qualifying interest from prospects who have already raised their hand. Outbound SDRs cold-prospect into target accounts, building pipeline from scratch. Both require skill; they require different skills.
Core skills that separate strong SDRs from the rest
Strong sales development representatives develop across three skill clusters. The technical skills get you in the door. The process skills keep you productive. The behavioral skills determine how far you go.
Technical skills
CRM proficiency (Salesforce, HubSpot): logging activity accurately, maintaining clean records, and using the system as a prospecting tool rather than a reporting burden
Sales intelligence tools: pulling verified contact data, building targeted lists, and using intent signals to prioritize outreach
Sequencing platforms (Outreach, Salesloft): building and managing multi-touch sequences, tracking engagement, and adjusting cadences based on response data
Process skills
Prospecting methodology: defining an ideal customer profile, building targeted account lists, and systematically working through them
Objection handling: responding to "not interested," "send me an email," and "we already have a solution" in ways that open conversations rather than close them
Qualification frameworks: using BANT (Budget, Authority, Need, Timeline) or similar frameworks to distinguish genuine opportunities from polite conversations
Behavioral skills
Resilience: absorbing rejection without letting it compound across the day or the week
Curiosity: asking questions that reveal real business problems rather than pitching features
Coachability: taking feedback from managers and peers and applying it the next day, not the next quarter
Accountability: owning your numbers without waiting for someone else to identify the problem
Two additional skills separate the modern SDR from the traditional one. Multi-threading means researching not just the primary contact but adjacent stakeholders and coworkers across the buying committee. A single-threaded deal is a fragile deal. Content delivery timing matters too: the best SDRs know that delivering relevant content to a prospect at the right moment in their research process is as important as booking the meeting itself.

How ZoomInfo's sales development program is structured
The ZoomInfo sales development program is built on a visible career path and a deliberate talent development philosophy. According to Brian Vital, Vice President of Sales Development at ZoomInfo, ZoomInfo hires SDRs from diverse backgrounds and ramps them to full productivity within a year.
"When it comes to career growth on the SDR team, what we found is that team leaders and managers are prone to helping other SDRs without a direct ask from management," Vital explains. "And you'll see it. If you joined our Slack channels or joined any of our Zoom huddles, you'll see like, 'Why is Jane speaking up and motivating the team when she's an individual contributor?' It's like, 'Oh, because Jane possesses this leadership quality that's really special.'"
ZoomInfo's SDR playbook maps every step of the career path, making the progression to management explicitly visible from day one. Every step and path along the way is documented, showing SDRs what they need to do to progress. That transparency is not incidental; it is the mechanism that makes the sales development program work. When people can see the path, they can move toward it deliberately rather than waiting to be noticed.
Vital notes that in the past year, SDR team members have moved into account management, sales leadership, marketing, and learning and development. "This kind of sales structure creates a team that naturally pushes out talent in sales and beyond," Vital says. "We need to make sure that our teams are ready within a year to move on and do greater things here at ZoomInfo."
The sales professional development philosophy here is not about keeping talent in the SDR seat. It is about building the kind of organization where moving up is the expected outcome, not the exception.
Finding the right fit: team lead or account executive?
Steven Bryerton, Vice President of Sales at ZoomInfo, makes a conscious effort to understand where each SDR fits in terms of the types of accounts and motions that suit them best.
"But you need to realize that motion isn't for everybody," Bryerton explains. "It might move outside of their depth because the conversations get more technical; you have to wrangle more people. There are account executives that are just great at understanding a small business and how they operate and providing value in getting them in the door quickly."
According to Bryerton, at the rate ZoomInfo is scaling, there is a real leadership component to the team lead and manager roles that makes it critical to distinguish leadership potential from individual performance. "More often than not, it doesn't work that way" when you promote your top quota carrier into management, he notes.
The signals Bryerton looks for are behavioral, not numerical: unprompted coaching behavior, thinking about pipeline differently than individual contributors, speaking up in meetings, and a tendency toward data-driven decision-making. Those are the people who ultimately work their way into a team leader or manager position when the opportunity arises.
This is the core insight of ZoomInfo's sales development approach: top performance is a baseline, not a differentiator for management readiness. A rep who hits 150% of quota but never coaches a peer, never surfaces a team-level pattern, and never speaks up in a group setting is not a leadership candidate. The rep at 110% who does all three things is. Understanding that distinction early saves organizations from promoting the wrong people and losing both a great seller and a potentially mediocre manager.
For SDRs considering the account management growth path, the AE track rewards technical depth, deal complexity management, and the ability to navigate multi-stakeholder buying processes. The team lead track rewards the behavioral signals above.
The SDR-to-team-lead path in practice
For Megan Hanisko, Team Lead at ZoomInfo, the path to leadership started with the behaviors Bryerton describes, long before she held the title.
"Our best team leads that are working their way to management, they've exhibited signs of team leadership. It's almost like this intrinsic thing," says Vital. "Once they get to team lead, we work with them to build out their actual management skills."
The team lead role at ZoomInfo is a structured development stage, not a title bump. It is where natural leadership tendencies get shaped into actual management capability through deliberate training and exposure.
Vital describes Hanisko's trajectory: "Megan has had management in her blood, I'm sure, for many years. So those sort of things come through naturally. She's in our management meetings now, and now she's like the leader of the team leads. So she just keeps working her way up more and more and more."
What makes Hanisko's approach worth examining is the accountability standard she holds herself to. The bottom line for roles like Team Lead or AE is a drive to do better, be better, and aim higher. For Hanisko, the role is about coaching other SDRs through hard times and good ones, and that comes down to personal accountability.
"The thought of me trying to coach someone on my team about time management when I'm not able to manage my own time, that seems kind of silly to me," she explains. "I feel like we've all had some sort of leader in our life that tells us to do something but they aren't really willing to do it themselves. We've all had the coach that's willing to go and run alongside you and put in the hours with you but we've also had others that stay on the sidelines. We don't do sidelines at ZoomInfo."
That philosophy is what makes sales professional development programs work at the team level: managers who model the behavior they expect, not just assign it. When a team lead holds themselves to the same standard they hold their reps, accountability becomes a cultural norm rather than a management directive. The "we don't do sidelines" framing is not motivational language. It is a description of how coaching actually functions when it works.
The same philosophy applies to the tools we put in their hands. GTM Workspace gives sellers a unified workspace so they spend time on pipeline, not on toggling between systems.
What a structured sales development program delivers
A structured sales development program does something an ad-hoc approach cannot: it creates predictable outcomes at scale. When the career path is documented, when leadership criteria are behavioral rather than arbitrary, and when coaching accountability runs both directions, SDR teams generate better pipeline and better talent for the broader organization.
The SDRs inside ZoomInfo's program are selling a platform built on three interconnected foundations: comprehensive B2B data, the GTM Context Graph intelligence layer, and GTM Workspace for unified seller access.
The data foundation is the starting point. ZoomInfo's B2B data platform covers 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business emails. For SDRs, that means fewer bounced emails, fewer dead-end dials, and more time on conversations that can actually move. Accurate data is not a nice-to-have for a team measured on pipeline generation; it is the operational foundation everything else runs on.
The GTM Context Graph is the intelligence layer that sits on top of that data. It processes 1.5B+ data points daily, fusing ZoomInfo's B2B data with CRM data, conversation intelligence, and behavioral signals into a unified reasoning layer. Where raw data tells you who to call, the GTM Context Graph tells you why now, surfacing the buying signals and account context that make outreach relevant rather than random.
GTM Workspace is where that intelligence becomes action. It consolidates prospecting, outreach, and account context into a single seller environment, so SDRs spend their time developing skills and building pipeline rather than stitching together context across five different tools.
ZoomInfo earned 133 No. 1 G2 rankings across Sales Intelligence, Buyer Intent, Data Quality, Lead-to-Account Matching, and Account Data Management (G2 Summer 2025), and was recognized as a Forrester Wave Leader for Intent Data Providers B2B with the highest scores across 8 criteria (Q1 2025). Those validations matter to SDRs because they reflect real-user trust at scale, not just analyst opinion.
For sales leaders building or evaluating an inside sales professional development program, the platform the SDRs sell shapes what they can credibly demonstrate to prospects. A team selling a platform validated at this level starts every conversation with a structural advantage.

How to build your own SDR development program
The principles behind ZoomInfo's program are replicable. Here is a four-step framework for sales leaders building or rebuilding their own.
Make the career path visible from day one. Document every step from SDR to Team Lead to AE to Manager in a written playbook. SDRs who can see the path move toward it deliberately. SDRs who cannot see it either wait to be noticed or leave. The playbook does not need to be elaborate; it needs to be specific about what each step requires and honest about the timeline.
Identify leadership potential early, and look at behavior, not quota. The signals that predict strong team leads are behavioral: unprompted coaching of peers, data-driven thinking about pipeline patterns, and speaking up in team settings without being asked. Quota attainment is a baseline, not a differentiator. Promoting your top performer into management because they are your top performer is one of the most common and costly mistakes in sales development program design.
Build management skills deliberately once someone reaches Team Lead. Natural leadership tendencies are the entry requirement for the team lead role, not the exit requirement. Once someone is in the seat, provide structured management training: how to run a one-on-one, how to coach on specific skills rather than outcomes, how to give feedback that changes behavior. Exposure alone is not development.
Create a feedback loop from SDR qualification data back to marketing. SDR disposition data, the reasons deals are disqualified, the objection patterns that recur, the personas that never convert, contains signal that should flow back to marketing to refine ICP targeting over time. Teams that close this loop generate better-qualified pipeline because the front-of-funnel criteria stay calibrated to what actually converts. Teams that do not close this loop keep sending SDRs into conversations the market has already told them will not work.
The right sales intelligence platform reduces the operational overhead at each stage. GTM Workspace consolidates prospecting, outreach, and account context so SDRs spend more time developing skills and less time toggling between tools.
Frequently asked questions about sales development
What is a sales development representative?
A sales development representative focuses on top-of-funnel pipeline generation: prospecting into target accounts, qualifying leads against defined criteria, and booking meetings for account executives. Unlike AEs who own closing, SDRs own the front end of the sales process. Modern SDRs are increasingly treated as specialized top-of-funnel experts rather than entry-level placeholders, and companies that make this shift consistently see stronger pipeline quality.
What do you mean by sales development?
Sales development refers to the function, processes, and roles focused on identifying and qualifying potential customers before passing them to account executives for closing. It encompasses both the SDR role and the broader pipeline-generation methodology, including prospecting, outreach sequencing, lead qualification, and the SQL handoff to sales. The function bridges marketing (which generates awareness and inbound interest) and sales (which closes deals).
Is an SDR role considered entry level?
Traditionally yes, but the framing is shifting. SDRs require a specialized skill set: CRM proficiency, prospecting methodology, objection handling, and increasingly multi-threading across buying committees. Companies that treat SDRs as top-of-funnel experts rather than entry-level placeholders, and back that up with structured development programs and visible career paths, consistently see better pipeline outcomes. The team lead role is often the next step for SDRs who demonstrate leadership behaviors early.
How long does it take to move from SDR to account executive?
Typical SDR-to-AE timelines range from 12 to 18 months, though this varies by company size, market, and individual performance. At ZoomInfo, the SDR playbook maps every step of the progression explicitly, including the criteria for Team Lead and AE tracks, so SDRs know what they need to demonstrate before the opportunity arises. For SDRs considering the AE path specifically, the account management growth article covers what that transition looks like in practice.
What qualities does a sales development team lead need?
The strongest team lead candidates show leadership before they are asked to: they coach peers without being prompted, think about pipeline differently than individual contributors, and speak up in team meetings. Top quota performance is a baseline, not a differentiator. The behavioral signals matter more than the number. Once in a team lead role, structured management training builds on those natural tendencies and turns them into repeatable coaching skills.
