11x.ai is the best pick for the most autonomous, agent-led outbound motion, Artisan is the best pick for a full AI sales rep handling research through follow-up, Regie.ai is the best pick when lead prioritization is the actual bottleneck, and HubSpot Breeze is the best pick if your CRM is already HubSpot. All four claim to replace or augment an SDR; the real differences are how much you have to configure, how autonomous the agent actually is, and whether it plugs into a CRM you already run.
The four, in one line each
11x.ai runs SDR-style prospecting and outreach with less manual configuration than the others, aimed at teams testing whether agent-led pipeline generation works at all before building a bigger process around it.
Artisan runs an AI sales rep — nicknamed "Ava" — that researches leads, writes outreach, and manages follow-up across a full outbound sequence, closer to hiring a junior SDR than renting a tool.
Regie.ai combines AI-written sequences with an agent layer that prioritizes which leads to work first, which matters once volume outpaces what a human can triage manually.
HubSpot Breeze is HubSpot's own AI layer — prospecting agents, content generation, call summaries, and CRM hygiene — built to work inside a CRM you're already paying for rather than alongside it.
Where each one actually wins
11x.ai wins for teams who want to test agent-led outbound with the least setup overhead — it's the pick for "let's see if this actually works" before committing to a bigger rollout. Artisan wins when you want something closer to a full hire than a tool: research, writing, and follow-up handled end to end, with less manual sequence-building. Regie.ai wins specifically when the problem isn't writing outreach — it's knowing which of a thousand leads to work first, which is a prioritization problem more than a content problem. HubSpot Breeze wins on integration: if your CRM, contacts, and deal pipeline already live in HubSpot, a native AI layer avoids the sync problems and the second login that come with a standalone agent.
A pattern we see often: teams already committed to HubSpot try Breeze first since it's close to free to test, and only move to a dedicated agent like 11x.ai or Artisan once they hit a ceiling Breeze wasn't built to handle.
Quick comparison
| Tool | Starting price | Core job | Best fit |
|---|---|---|---|
| 11x.ai | Custom pricing | Autonomous outbound prospecting | Testing agent-led outbound with minimal setup |
| Artisan | Custom pricing | Full AI sales rep across the sequence | Teams that want research + writing + follow-up handled end to end |
| Regie.ai | Custom pricing | Lead prioritization + AI sequences | High lead volume that outpaces manual triage |
| HubSpot Breeze | From $20/mo | Native AI inside HubSpot | Teams already running their CRM on HubSpot |
Which one should you use?
Start with HubSpot Breeze if you're already on HubSpot and want to test AI-assisted outbound without adding a new tool. Move to 11x.ai if you want to test a more autonomous, agent-led motion from a clean slate. Choose Artisan if you want something closer to a full AI rep than a sequence-writing tool. Reach for Regie.ai specifically when lead prioritization, not content, is what's actually slowing pipeline down.
FAQ
Can an AI SDR agent fully replace a human SDR? Not reliably yet for the judgment-heavy parts — qualifying genuinely ambiguous leads, handling objections in real time. Most teams use these agents to handle volume (research, first-touch outreach, follow-up) and keep a human for the conversations that actually convert.
Do I need to already have a CRM in place? For HubSpot Breeze, yes — it's built into HubSpot specifically. The other three can generally connect to whatever CRM you already run, though setup complexity varies.
Which is cheapest to test first? HubSpot Breeze has the clearest published starting price ($20/mo) if you're already paying for HubSpot. The other three are typically custom-quoted, so getting an actual number usually requires a call.
