Simple yes-or-no questions that will help you decide.
Is your ICP and messaging proven?
You know your ICP and what works. AiSDR scales execution from here.
Agencies help you figure out positioning and ICP before scaling.
Is the execution speed your biggest bottleneck?
First campaign can go live in the first 30 minutes of using AiSDR.
A longer ramp gives an agency time to build a deeper strategic foundation.
Do you have someone to manage outbound weekly?
Your team sets strategy. AI Strategist executes continuously.
When internal bandwidth is zero, agencies absorb the entire workflow.
Is in-person selling core to your motion?
Human SDRs still have the edge for high-touch field work and cold calls.
If no handshakes are needed, have AiSDR run email and LinkedIn end to end.
6 situations. 6 honest answers.
Some of these belong on AiSDR. Some don’t.
A founder running outbound between investor meetings, no SDR hired yet, needs leverage today.
You know your product cold, and AiSDR carries that founder voice across hundreds of prospects in days.
3-10 AEs in place with a solid closing rate, but not enough discovery calls to fill the calendar.
It plugs into your CRM and feeds your AEs directly, with no new hires.
Each fully-loaded BDR runs $120K–$210K/year, with 34–40% annual turnover
You get consistent outbound at a fraction of that cost, with faster ramp and no turnover risk.
6-figure deals to 5-12 stakeholder buying committees. In-person meetings and phone-based rapport-building drive most progress.
When deals advance through in-person relationship-building, human teams win.
Entering a market where outreach style and business norms differ significantly from your home market. Cultural fluency is critical.
Native-speaker SDRs bring cultural fluency that AI can’t reliably replicate yet.
Strategic accounts that need both precision digital outreach and in-person field work to advance.
AiSDR runs the digital channels with per-account research, while an agency or your team handles in-person meetings.
Many teams start with an agency for 3–6 months, then switch to AiSDR.
Let an agency prove the playbook and then bring execution in-house with AiSDR at a fraction of the cost.
Common risks and how each approach addresses them
Agencies manage infrastructure for you. Less hassle day-to-day.
Tradeoff: You typically don’t own the warmed domains. Switching providers means starting over.
You own every domain and mailbox, with automated warmup and rotation.
Tradeoff: Your team needs to understand the basics of domain health.
Human researchers curate target lists with vertical knowledge.
Tradeoff: List size and refresh rate are limited by rep capacity.
Signal-based search across the web, refreshed continuously.
Tradeoff: Quality depends on how you’ve configured ICP filters.
Human copywriters can adapt voice and tone for each campaign.
Tradeoff: At volume, reps typically fall back on templates. Quality varies by rep.
Deeply researched messages built from intent signals, recent posts, and company context, not bio scrapes.
Tradeoff: Review the first batches closely until your AI persona is dialed in.
Reps can read nuance in a tricky reply and use judgment.
Tradeoff: Business hours only. Weekend leads wait until Monday.
Replies classified and answered in under 10 minutes, 24/7. AI cleverly navigates the objections.
Tradeoff: Truly edge-case replies still need a human handoff.
Agencies own the infrastructure and signed DPAs.
Tradeoff: Your customer data lives in their system. Auditing happens on their schedule.
GDPR-compliant regional processing. SOC 2 certified. Data and audit logs live in your tenant.
Tradeoff: You’re the data controller. Configure compliance settings for your jurisdiction at setup.
Monthly reports with curated metrics. Account manager for deep dives.
Tradeoff: Raw activity data typically not exported. Logging varies by agency.
Real-time HubSpot and Salesforce sync. Every message, reply, and meeting visible.
Tradeoff: Your RevOps team tackles the analysis an agency would otherwise deliver as a monthly report.
Common myths about AI SDRs vs outreach agencies
Bad AI reads like spam. Researched AI doesn’t.
AI emails read generic when they’re built from bio scrapes. AiSDR researches each prospect live before writing. Customers regularly hear back “this is the best cold email I’ve received.”
AiSDR pulls 9.2% reply rates, about 10× the cold-outreach baseline. The replies themselves are worth a read on our Wall of Love.
Beginners often hire agencies expecting expertise, but 70% of those engagements fail to deliver ROI.
AiSDR’s AI Strategist gives you the expertise inside the platform, so no outbound background is required.
AiSDR turns onboarding into your first campaign building session, requiring only your website’s URL and your ICP.
Both models require oversight.
Agency vetting checklists consistently warn that without clear goals and weekly pipeline review on the client side, engagements fail. AiSDR requires similar oversight.
88% of AI SDR pilots and 70% of agency engagements fail when client oversight is missing.
Only the mailboxes stay behind.
Your ICP and CRM data travel with you. AiSDR’s Live Onboarding rebuilds the infrastructure in under 2 hours.
Teams that switch to AiSDR launch their first campaign before their old agency contract even expires.

Frequently Asked Questions
What’s the main difference between AiSDR and an outreach agency?
AiSDR is a platform you own and operate. An SDR agency is a service you contract with. AiSDR’s AI does the day-to-day work while your team sets direction. Agency reps do that work, but on their schedule and with the people they assign.
Can AiSDR really replace a full SDR agency?
For most B2B teams, yes. AiSDR handles prospecting, research-driven outreach, reply handling, objection management, and meeting booking on one platform.
Agencies still have the edge on enterprise deals where humans need to build relationships across multiple stakeholders over months.
How fast can AiSDR generate pipeline?
Launching takes under 2 hours with Live Onboarding. Pipeline follows quickly. If your ICP is spot-on, the first positive reply lands within the first ~50 messages sent. Results like 1–3 qualified meetings per 100 leads contacted are realistic.
What does AiSDR do about email deliverability?
Deliverability is built into the platform from day one.
AiSDR handles on your behalf:
- domain procurement
- mailbox creation
- warmup
- inbox rotation
- bi-weekly deliverability testing
One of the most common things we hear from new customers is that their previous setup burned their domain. AiSDR is built specifically to prevent that.
We tried AI outreach before and it didn’t work. What’s different here?
Past AI outreach usually failed because targeting was too broad and messages template-based. AiSDR fixes both with real-time intent signals and having every message live-researched and relevant.
