Topo

What is Topo, exactly?

Topo is an outbound prospecting AI agent created by former executives from Aircall and backed by Y Combinator. The principle is simple: you configure your ICP (ideal customer profile) and your sales playbook, then Topo executes all of your prospecting autonomously.

Concretely, the tool identifies leads matching your criteria, writes personalized emails and LinkedIn messages, manages follow-ups automatically, classifies responses, and books meetings directly into your calendar. All without an SDR needing to manually intervene.

Topo also manages email infrastructure internally (domains, mailboxes, warmup), which eliminates the need to configure all of that yourself. Updates arrive directly in Slack, so you can keep an eye on performance without leaving your workflow.

Key features

Autonomous email + LinkedIn prospecting

Topo creates and executes multi-channel sequences (email and LinkedIn) from start to finish. The AI writes each message while adapting to the prospect's context: industry, position, detected intent signals. Follow-ups are automatically calibrated based on previous interactions.

Response classification and routing

When a prospect responds, Topo analyzes the message and classifies it: interested, not interested, information request, objection, out-of-office. Positive responses are routed to your sales team, objections are handled automatically with an appropriate response.

Third-party intent signals

The tool leverages signals from LinkedIn, G2, and GitHub to identify prospects most likely to be receptive to your approach. This allows you to prioritize hot leads rather than spray and pray.

Integrated email infrastructure

No need to manage your sending domains and mailboxes separately. Topo handles creation, warmup, and rotation of email addresses. It's a huge time-saver compared to manual setups with tools like Lemlist or Woodpecker where you have to configure everything manually.

Topo pricing in 2026

Topo offers three plans. The pricing positioning is premium, clearly aimed at teams who want to replace (or complement) a human SDR.

• Agent Plan: $900/month for 1,000 leads contacted per month. That's roughly $0.90 per lead contacted.
• Growth Plan: around $2,000/month with expanded lead volume, suited for scaling teams.
• Pro Plan: custom pricing for enterprise needs with advanced features.

For perspective: a junior SDR costs between $3,000 and $5,000 per month all-in. If Topo can generate a comparable volume of qualified meetings, the ROI is clear. But that's a big "if"—we'll dive into it more below.

Strengths and limitations

After reviewing user feedback, here's what stands out.

What works well:

• ✅ Fast setup: you can launch your first campaigns in a few hours, not weeks.
• ✅ Zero manual intervention: once your playbook is configured, Topo runs in complete autonomy.
• ✅ Turnkey email infrastructure: no more juggling secondary domains and warmup.
• ✅ Native Slack integration: updates arrive where your team already works.
• ✅ Strong founding team with proven scaling experience (ex-Aircall, YC-backed).

Limitations to be aware of:

• ❌ Message personalization can lack depth on complex or highly niche ICPs.
• ❌ No built-in phone/dialer functionality: if your sales motion also relies on cold calling, you'll need a complementary tool.
• ❌ Performance can degrade on large data volumes or massive-scale campaigns.
• ❌ Response metrics are sometimes overstated compared to actual outcomes (meetings booked).

Who is Topo for?

Topo is primarily aimed at startups and SMBs that don't (yet) have a dedicated SDR but want to do serious outbound prospecting. It's also relevant for solo founders managing everything who don't have time for manual prospecting.

If your sales cycle relies exclusively on email + LinkedIn, Topo can cover the essentials. However, if you need cold calling, visitor identification, or an AI chatbot, you'll need to complement it with other tools like Apollo (which integrates phone) or Crisp for chat.

More mature teams with SDRs in place can use Topo as a complement to increase outreach volume without hiring. But be warned: the tool doesn't replace the finesse of a human on complex enterprise deals.
