Overloop AI vs Warmly in 2026: AI outbound prospecting vs autonomous inbound visitor engagement
Overloop AI goes looking for a prospect in a 450M-person database and cold-emails them. Warmly waits for that same kind of buyer to show up on your website anonymously, identifies them by name, and lets AI agents take it from there. Outbound versus inbound, at wildly different price points.
Overloop AI
Warmly- Overloop AI starts at $69 per user per month; Warmly starts at $10,000 per year with no self-serve signup of any kind.
- Overloop AI runs outbound campaigns against a 450M+ prospect database; Warmly identifies and engages inbound website visitors who have not filled out a form yet.
- Warmly's Context Graph unifies site visits, CRM data, calls, and chat logs into a real-time account view; Overloop AI has no comparable cross-channel data layer.
- Overloop AI includes automated meeting booking and native LinkedIn outreach; Warmly's engagement is chat, email, and ad retargeting rather than LinkedIn sequencing.
- Warmly runs autonomous AI agents with self-improving chat and qualification logic; Overloop AI's AI drafts campaign copy and searches a database rather than running autonomous engagement decisions.
- Warmly customers report replacing $20,000-$40,000/month in SDR agency spend, a scale of investment with no equivalent framing in Overloop AI's per-seat pricing.
Overloop AI is an outbound prospecting platform combining a 450M-plus database with AI-generated email campaigns and email-plus-LinkedIn sequencing, priced per user starting at $69/month. Warmly is an enterprise inbound GTM platform that de-anonymizes website visitors at the person level and deploys autonomous AI agents to engage them across chat, email, and ads, starting at $10,000 a year with no self-serve option. Both use AI to reduce manual sales work, but Overloop AI's AI goes hunting in a database for someone who does not know you exist, while Warmly's AI waits for someone who is already curious enough to visit your site and tries to catch them before they leave anonymously.
The tools at a glance
Overloop AI
AI-powered sales prospecting that builds your lead list, writes the email, and books the meeting without manual effort.
Overloop AI is built entirely around outbound: describe your ICP and the platform searches its 450M-plus database, generates personalized email copy per segment using company and role signals, and runs the resulting campaign across email and LinkedIn from a single dashboard. Automated meeting booking captures positive replies without a rep manually sending a calendar link.
Campaign analytics track open, reply, and meeting conversion rates at the segment level, feeding progressive refinement of both targeting and copy. This is a cold-start motion by design, the platform assumes no prior relationship with the recipient and builds the entire workflow around initiating one.
At $69 per user per month, Overloop AI is accessible to a small sales team without a large budget commitment, though CRM integrations require the $99 Growth tier. It has no website visitor identification capability of any kind and no autonomous agent architecture, its AI generates copy and searches a database rather than making independent engagement decisions.

Warmly
AI agents de-anonymize website visitors at the person level and autonomously run inbound and outbound GTM across chat, email, and ads.
Warmly answers a question Overloop AI cannot: who is on your website right now, before they ever fill out a form or reply to a cold email. Its de-anonymization layer resolves anonymous traffic to individual identities, feeding into a Context Graph that unifies site visits, CRM records, call transcripts, chat logs, and ad engagement into a real-time account picture.
AI agents act on that Context Graph directly rather than following a pre-built campaign sequence: the Inbound Agent triggers chat and follow-up email based on visitor identity and intent signals, and the top AI Inbound Autopilot tier runs unlimited AI Studio Agents that qualify leads and self-improve their chat responses over time, operating in a human-supervised model.
None of this is accessible below $10,000 a year, with every tier requiring a sales conversation and add-ons like GTM Signals costing another $10,000 a year each. Warmly does have a TAM Agent for coordinated outbound too, but its core strength and pricing logic are built around identifying and engaging inbound traffic rather than cold-searching a database the way Overloop AI does.
| Feature | AI Web-Deanonymization From $10,000/year | Inbound Chat From $20,000/year | AI Inbound Autopilot From $30,000/year |

| Person-level visitor ID | ✓ | ✓ | ✓ |

Which should you choose?
Overloop AIWarmlyOverloop AIWarmlyOverloop AIWarmlyThese two tools automate opposite motions and sit at opposite ends of the pricing spectrum, which makes a direct comparison mostly a way to sanity-check which problem you actually have. Overloop AI is accessible to a two-person sales team on a modest monthly budget looking to cold-email a defined ICP. Warmly requires a five-figure annual commitment and is built for a company with real inbound website traffic and either an SDR budget to redirect or an account-based program in place. Neither one is a scaled-down or scaled-up version of the other, they are different tools for different funnel stages entirely.
Bottom line
Pick Overloop AI if your team is small, budget-conscious, and needs to cold-email a defined ICP with AI-generated copy and LinkedIn outreach bundled in. Pick Warmly only if you have meaningful inbound website traffic and either an SDR budget you want to redirect or an enterprise ABM program that needs person-level visitor identification, and only after a pilot confirms the match rates justify the $10,000 floor. A company running both an outbound motion through Overloop AI and inbound visitor engagement through Warmly is plausible at the mid-market stage, but very few teams need to choose between them as competitors.
Frequently asked questions
Can Overloop AI identify anonymous website visitors the way Warmly does?
No, Overloop AI has no website visitor de-anonymization capability, its entire product is built around searching an external database of 450 million-plus prospects for cold outreach. Warmly's core feature is resolving anonymous site traffic to named individuals, which is a fundamentally different data capability Overloop AI does not attempt.
Is Warmly worth the $10,000 minimum for a small sales team already using Overloop AI?
Probably not yet, since Warmly is priced against replacing significant SDR agency spend or capturing meaningful inbound website traffic, neither of which a small team relying primarily on Overloop AI's outbound prospecting is likely to have at scale. Warmly becomes worth considering once a company has real inbound volume and budget to justify the investment.
Does Overloop AI have autonomous AI agents like Warmly's AI Studio Agents?
No, Overloop AI's AI generates personalized campaign copy and searches its prospect database based on your ICP description, but it does not run autonomous, self-improving engagement decisions the way Warmly's AI Studio Agents do. Overloop AI's automation is campaign-based rather than agent-based in that sense.
Which tool includes automated meeting booking?
Overloop AI includes automated meeting booking on every tier starting at $69 per user per month, converting positive replies into scheduled calls automatically. Warmly's engagement model is centered on chat, email follow-up, and ad retargeting for identified visitors rather than a dedicated meeting-booking mechanism as its primary conversion path.
Can a company use both Overloop AI and Warmly for different parts of the funnel?
Yes, this is a coherent setup for a mid-market B2B company, using Overloop AI for outbound cold prospecting against a defined ICP while using Warmly to identify and engage anonymous inbound website visitors who have not yet filled out a form. The two tools address genuinely separate parts of a GTM motion rather than competing for the same budget line.
What kind of company should not consider Warmly at all in 2026?
Companies with low or inconsistent website traffic, no existing SDR spend to redirect, and a limited marketing or sales budget are poor fits for Warmly, since its $10,000-plus annual pricing assumes enough traffic volume and budget scale to generate a return. A small team in that position is better served by a lower-cost outbound tool like Overloop AI or a dedicated visitor identification tool with a lower price floor.
