The median BDR/SDR org runs at 1 SDR per 2-3 AEs, with $50-70K base comp, $80-110K OTE, and 30-40% first-year attrition (Bridge Group 2024 SDR Metrics Report; RepVue 2024 compensation data). Those numbers have held roughly steady for three years, but the composition of the org is changing fast. AI SDR tooling has entered the room, hybrid inbound/outbound roles are being unbundled again, and the question of whether the BDR function even reports to sales anymore is genuinely open.
Here is how I think about the structure of a modern BDR team, and what the data says about the decisions that matter most.
Reporting line: the actual debate
Whether BDRs report to Sales or Marketing has been argued about for a decade. There are real trade-offs.
Reporting to Sales. Tightest alignment with AEs. Fast feedback loops on meeting quality. Clearest SDR-to-AE promotion path. This is the default at Series B-D companies, and for good reason: the person receiving the meeting is the best judge of whether the meeting was worth taking.
Reporting to Marketing. Better alignment with campaigns and lead scoring. Stronger MQL discipline. Marketing owns the top of funnel already, so there is an argument that the humans working the top of the funnel should sit inside marketing.
The verdict from what I see in the market. Most Series B-D teams still report to Sales. At Series C+, a hybrid model is common: inbound SDRs report to Marketing (they are qualifying MQLs that Marketing sourced), outbound SDRs report to Sales (they are building pipeline generation motion that AEs will inherit). This split reduces the classic MQL-fight-with-sales problem and gives outbound SDRs a clearer promotion path.
Ratio: SDR to AE
There is no universal ratio. The right number is a function of motion, ACV, and how mature outbound is.
- Early stage. 1 SDR to 2 AEs. SDRs are hard-won at this stage; AEs need to be self-sufficient early.
- Mature outbound motion. 1:1 to 1:2 SDR:AE ratio. This is the range for most mid-market SaaS companies with a working outbound machine.
- Enterprise. 1:1. Fewer accounts, higher-touch, deeper research per account.
- PLG-heavy. 1:3 or thinner. Product does most of the sourcing; SDRs qualify and pass.
Ratios that skew too heavy on SDRs (2 SDRs per AE or more) are usually a sign that AE productivity is the actual constraint, not top-of-funnel supply. Adding more SDRs into that situation does not fix the pipeline — it just fills more calendars with meetings that do not convert.
Compensation (US, 2026)
Base bands from RepVue and Bridge Group, adjusted for 2026 market data:
- Entry SDR (0-12 months experience): $50-65K base, $75-95K OTE
- Senior SDR (12-24 months, top performer): $60-75K base, $95-120K OTE
- SDR Manager: $110-140K base, $160-200K OTE
- Director of SDR (multi-manager): $150-190K base, $220-280K OTE
Geographic variance is real. West Coast and NYC pay 15-20% above these ranges. Remote-first teams sitting in Tier 2 cities tend to pay 10-15% below.
Ramp expectations: full quota carry by month 4, meaningful meeting production by month 2-3. Ramp longer than five months is a sign the enablement content is not landing.
Segmentation: what shape of SDR to hire
Four main archetypes, and they are not interchangeable.
Inbound SDR. Qualifies MQLs generated by marketing. Volume: 15-25 meetings booked per month. Best for high-signal MQLs (demo requests, high-intent content downloads). Comp skews slightly lower base, higher variable.
Outbound SDR. Builds pipeline from cold. Volume: 8-15 meetings per month. Needs research skills, message-craft, and resilience. Comp skews slightly higher base because ramp is longer.
Named-account SDR. Assigned 30-100 named accounts, deep research, orchestrates across the buying committee. Volume: 5-10 meetings per month, but each one worth 10x an inbound meeting. Comp bands 15-25% above generalist outbound.
Hybrid. Splits day between inbound and outbound. Almost always less effective than specialists — the context-switching cost is real. Bridge Group data has shown hybrids underperform pure-outbound SDRs by 20-30% on qualified pipeline created. Use this shape only at Series A or when volume genuinely does not support two specialists.
Territory and account allocation
The other structural decision most orgs get wrong is how many accounts to hand each SDR. There is a hard trade-off between coverage and depth, and getting the ratio wrong is one of the top three drivers of SDR attrition.
- Named-account outbound: 30-100 accounts per SDR. This is the model for enterprise motion. Deep research, multi-threaded outreach, patience. Meeting output is lower but pipeline value per meeting is 5-10x higher.
- Territory outbound (mid-market): 150-300 accounts per SDR. Enough surface area to run cadences at scale, but small enough to remember who each account is.
- High-volume outbound (SMB): 500-1,000 accounts per SDR. Cadence-driven, less personalization, higher activity metrics. This is also the shape most vulnerable to AI SDR replacement.
- Inbound: account-count is meaningless. Inbound SDRs work off lead flow, and the right metric is speed-to-lead (target: under 5 minutes) and MQL-to-meeting conversion (target: 20-30%).
The pattern I see fail most often: assigning 800 accounts to an SDR expected to run named-account motion, or 100 accounts to an SDR expected to run SMB volume. The wrong shape of book for the wrong shape of motion produces burnout and mediocre results at the same time.
Cadence and sequence design
Median outbound sequences run 8-14 touches over 3-5 weeks across email, phone, LinkedIn, and (increasingly) SMS. The best-performing sequences in 2026 are shorter than they were in 2022 — buyers are exhausted, and long sequences are being rewritten as spam by the models that filter them.
- Median sequence length: 10 touches over 3 weeks
- Reply rate for cold sequences: 1-3% (down from 3-5% in 2022, per Gong 2025)
- Reply rate for warm-intro-sourced sequences: 30-50%
- Optimal touch mix: 4-5 emails, 3-4 calls, 2-3 LinkedIn touches, 1 personalized video or voice note
The specific composition matters less than the discipline of running the sequence to completion. Bridge Group data has consistently shown that SDRs who complete their full cadence generate 40-60% more meetings than SDRs who bail after the first two touches.
Career path: promotion is the retention story
The dirty secret of the SDR role is that only 25-35% of SDRs actually get promoted to AE, according to RepVue data. The rest churn, move laterally, or leave the industry. Median tenure is 14-24 months, and median time-to-promotion (for those who do get promoted) is 18 months.
Better managers cut the churn in half. What they do differently:
- Clear promotion criteria published from day one
- Weekly 1:1s with career development as a standing item
- Real coaching on discovery calls, not just prospecting cadence
- Shadowing time with AEs on real deals within the first 90 days
If your SDR org has less than a 40% promotion rate over a two-year window, the problem is almost never the SDRs. It is the management layer.
Manager span
Industry standard is 5-8 SDRs per manager.
- Below 5. Over-managed and expensive. Coaching quality is good but ROI is poor.
- 8 or above. Coaching quality drops. Managers spend time on operations rather than development. Attrition ticks up.
- Sweet spot. 6-7 direct reports. This gives the manager 90-120 minutes per rep per week for coaching, which is roughly the threshold at which coaching quality holds up.
Managers should carry no personal quota. Player-coach models below the manager tier are fine (senior SDRs mentoring juniors); above the manager tier they consistently underperform.
The AI SDR debate
The most important structural question in 2025-2026 is whether to build human SDRs, AI SDRs, or both. The honest answer is both, but the boundary matters.
Where AI SDRs win. High-volume, low-ACV inbound qualification. Top-of-funnel prospecting where the goal is coverage rather than quality. Data enrichment and account-level research at scale. Simple follow-up sequences.
Where AI SDRs lose. High-ACV enterprise motion. Relationship-heavy segments. Warm-intro orchestration. Anything that requires reading the room on a discovery call. Named-account motion where each touch needs to be right.
The data. AI SDR platforms (11x.ai, Regie, Artisan) can send 10x the volume at 20-30% of the fully-loaded cost of a human SDR. But reply rates run 30-50% lower than human SDRs on cold outreach, and 60-70% lower on personalization-heavy segments (Sales Hacker 2025; Winning by Design benchmarks). Positive reply rates — the ones that actually convert to pipeline — track even worse.
Where this lands. A hybrid model is emerging: AI SDRs handle high-volume low-touch top-of-funnel work, human SDRs handle named-account motion and multithreading across the buying committee. The teams doing this well are not replacing human SDRs — they are letting AI SDRs cover the volume that used to burn out humans, and letting humans do the work that AI cannot yet do well.
If you are structuring for 2026, the question is not human vs. AI. It is which segment gets which shape, and how they hand off to each other cleanly.
Frequently asked questions
What is the right SDR-to-AE ratio? 1:2 at early stage, 1:1 to 1:2 for mature outbound motions, 1:1 for enterprise, 1:3 for PLG-heavy motions. Ratios that skew heavier on SDRs are usually a sign that AE productivity is the real constraint.
Should BDRs report to Sales or Marketing? Most teams report to Sales. Series C+ often runs a hybrid model: inbound SDRs to Marketing, outbound SDRs to Sales. The hybrid model reduces the classic MQL-fight-with-sales problem.
What is the median SDR compensation in 2026? $50-70K base, $80-110K OTE for entry-level. Senior SDRs land at $60-75K base and $95-120K OTE. Data from RepVue and Bridge Group. West Coast and NYC add 15-20%.
How many SDRs should a manager have? 5-8 direct reports. Sweet spot is 6-7. Below 5 is over-managed; above 8 is under-coached. Managers should not carry personal quota.
Should we hire AI SDRs? For high-volume low-ACV inbound qualification, yes. For high-ACV enterprise, named-account motion, or relationship-heavy segments, no — reply rates on personalization-heavy segments run 60-70% below human SDRs (Sales Hacker 2025). Most Series B-D teams are landing on a hybrid model.
What promotion rate should we expect from SDR to AE? Median is 25-35% over a two-year window (RepVue). Well-run teams get to 45-55%. Below 25% is a management problem, not an SDR problem.
How long should SDR ramp be? Meaningful meeting production by month 2-3, full quota by month 4. Ramp longer than five months indicates enablement content is not landing.
