AiSDR vs Topo
TL;DR: Which one should you choose?
5 ways to choose AiSDR over Topo
AiSDR’s Live AI Search finds prospect data from scratch when you launch a campaign. You get current job titles, valid email addresses, and fresh context instead of relying on an older list.
Topo combines its lead database with web research, signals, and enrichment providers. It keeps lists refreshed, but its search still starts from a broader database-and-enrichment model rather than building the audience from live research first.
With AiSDR, you turn fresh buying signals into outreach before interest cools. It pairs the trigger with prospect context, starts the right message fast, and keeps replies and follow-ups moving without waiting on your team.
Topo also works with intent signals. The difference is how quickly that signal turns into a full conversation, not just another task for your team to pick up.
With AiSDR, your team sets the direction and AI GTM Engineer handles the execution, from prospect research and outreach to replies and campaign adjustments. Your team can step in anytime without becoming a workflow.
Topo’s campaign workflow keeps reps involved in reviewing leads, messaging, and campaign changes as they run. That gives teams more hands-on control, but also means more campaign decisions stay with your team day to day.
AiSDR works both the leads already coming to you and the prospects you want to reach. It scores intent, decides who needs immediate outreach, and moves lower-intent leads into the right nurture sequence without your team managing separate workflows.
Topo is built primarily for outbound prospecting. It uses inbound activity as an intent signal, but inbound qualification and follow-up still need a separate motion.
With AiSDR’s Ami, you don’t have to stare at a blank doc wondering what campaign to run next. Drop in your website, and it’ll analyze what you sell, who you sell to, and where the opportunity is. Ami will then generate GTM plays with different audiences and angles to explore.
Topo pairs its platform with strategy workshops and dedicated outbound experts who help shape your ICP, signals, and messaging. That hands-on guidance can be valuable, but your team still owns the strategy and works through the setup and calibration process before those ideas become campaigns.

Frequently Asked Questions
What is Topo? 
Topo is an AI-powered outbound platform built to work alongside your sales team. Its agents find and qualify leads, track buying signals, and run multichannel outreach across email and LinkedIn. Slack integration keeps your team in control of strategy and approvals while the AI handles prospecting, research, and follow-ups.
What does Ami do in AiSDR?
Ami is AiSDR’s AI Agent. Give Ami your website, and it analyzes what you sell, who you sell to, and where there may be an opportunity worth pursuing. It then generates GTM plays with different audiences, campaign angles, and reasons to reach out now.
Once you choose a play, AiSDR can turn it into prospect targeting, messaging, sequences, and outreach from the same platform.
What happens after Ami creates my GTM plays?
Each play gives you a potential audience, campaign angle, and reason buyers may care now. Choose the direction that fits your goals, then bring it into AiSDR to build the prospect list, research the buyers, create the messaging, and launch the outreach.
Ami can also use your campaign context and results to help shape what you test next.
How does personalization work in AiSDR vs Topo?
Personalization has become a catch-all term. The real test is whether a message reflects what the prospect cares about right now. AiSDR uses live web research, CRM context, and intent signals to build outreach around timely, relevant context.
Topo also uses AI to tailor outreach, but keeps more of the message structure and review process in your team’s hands. AiSDR can build each message from scratch and carry that context through the conversation, from the first touch to the reply.
The best proof is the response itself. AiSDR’s Wall of Love features real feedback from prospects and customers who called out the quality of the outreach they received.
How do AiSDR and Topo handle email deliverability?
Email landings in inboxes rather than spam folders require good domain setup, mailbox warmup, authentication, and active reputation monitoring.
AiSDR and Topo handle deliverability infrastructure for you.
Topo’s Premium Inboxes service sets up secondary domains and mailboxes, configures SPF, DKIM, and DMARC, and automatically warms up new inboxes. The platform also runs bi-weekly spam tests and adjusts sending volumes when mailbox health changes.
AiSDR handles domain setup, mailbox configuration, warmup, deliverability checks, and ongoing inbox health monitoring. Campaigns are capped at 30 emails per mailbox each day and 100 per domain to help protect sender reputation as outreach scales.

Both platforms automate campaign sending, but they differ in how much human review stays in the workflow.
AiSDR can handle replies, follow-ups, objections, qualification, and meeting booking without waiting for message-by-message approval. Conversations keep moving even when your team is busy elsewhere.
Topo uses a human-in-the-loop model through Slack and Microsoft Teams. The Ai can draft responses and recommend next steps, while your team stays responsible for reviewing lead quality and messaging before the conversation moves forward.
For teams that prioritize faster responses and less day-to-day oversight, AiSDR offers a more autonomous workflow.

Both platforms integrate with HubSpot. AiSDR also offers a native 2-way Salesforce integration, while Topo currently supports HubSpot only.
Topo’s 2-way HubSpot integration imports CRM data and writes interactions, exclusions, and activity logs back to HubSpot, keeping outbound activity synced with your existing setup.
AiSDR connects with both HubSpot and Salesforce and turns CRM lists and reports into active campaigns. The AI can score accounts, use custom fields and activity history to personalize outreach, add context through live web research, and write sends, replies, and booked meetings back to your CRM. Your CRM stays the source of truth while AiSDR turns the data inside it into a pipeline.
Can AiSDR handle both inbound AND outbound leads?

Topo focuses on outbound only, finding and contacting prospects through multichannel campaigns. Teams that want one AI workflow across both sides of the funnel get broader coverage with AiSDR.

Harmix booked 19 meetings with an 8.38% response rate and a 52% reply-to-demo rate after moving its outbound campaigns to AiSDR.
Topo uses a copilot model that keeps your team involved in reviewing outreach and moving conversations forward. AiSDR takes more of that work off your plate, carrying prospects from the first message through replies, objections, follow-ups, and meeting booking. That means fewer handoffs, less daily oversight, and more room for your team to focus on the conversations already worth having.
