Amplemarket is a sales engagement platform that bundles its own contact database (200M+ verified contacts with under 3% bounce rate), multichannel outreach, and an AI layer called Duo into one system, rather than a data-enrichment layer teams wire up themselves. Duo Copilot is the agentic core. It monitors 100+ contact-level buying-intent signals a day (job changes, competitor G2/review mentions, community activity, website visits, custom CRM signals) and surfaces ranked leads with drafted, personalized outreach for a rep to review, not send automatically. Founded in San Francisco in 2019 by CEO João Batalha, CPO Luís Batalha and CRO Micael Oliveira, the company has raised a disclosed $12M across back-to-back seed and Series A rounds co-led by Comcast Ventures and Armilar Venture Partners, announced April 2022. Amplemarket was named a Gartner Cool Vendor in Generative AI for Sales in 2024, one of five vendors on that list.

| Fact | Value |
| --- | --- |
| Website | https://www.amplemarket.com |
| Pricing | Startup starts at $600/month billed annually for 2 seats. Growth (4 seats) and Elite (10 seats) are custom-quoted. A 14-day free trial is offered. Phone credits top up at $0.50 each. |
| API | Yes |
| Best for | B2B sales teams that want prospecting data, multichannel sequencing and an AI signal-detection copilot in one platform, with a human still reviewing every message before it sends. |
| Not for | Teams specifically wanting a fully autonomous AI SDR that sends outreach without per-message human review. 11x or Artisan are built for that job. Amplemarket is deliberately not. |

## Pricing

| Tier | Price |
| --- | --- |
| Startup | $600 / month, billed annually, 2 seats included |
| Growth | Custom (Custom, 4 seats included) |
| Elite | Custom (Custom, 10 seats included) |

## Verdict

Amplemarket's real pitch is consolidation with a human still at the wheel. Contact data, multichannel sequencing, and AI-driven signal detection live in one platform. Duo Copilot drafts and prioritizes outreach without ever sending it unsupervised. That is a genuinely different bet from 11x or Artisan's fully autonomous AI SDRs, and from Clay's build-your-own enrichment workspace. Amplemarket ships a ready-to-use system, not a kit. A large, strongly positive G2 review base and a 2024 Gartner Cool Vendor nod back up a company that is not a brand-new entrant. The honest catches. Published, self-serve pricing stops at 2 seats ($600/month). The live pricing page and Amplemarket's own pricing blog continue to disagree on the Startup tier's credit numbers (13,500 vs 15,000 email credits per user per year, and 600 vs 480 phone credits per user per year). Disclosed funding ($12M, last announced in April 2022) remains modest next to several category peers, with no newer round publicly announced. Pick Amplemarket if you want prospecting data, sequencing, and AI signal detection in one place with a human approving every send. Pick 11x or Artisan instead if you specifically want autonomous send-without-review. Pick Clay if you want to build a custom enrichment workflow rather than take a bundled one.

## How it works

1. Duo's signal-detection layer monitors 100+ buying-intent sources daily (job changes, competitor reviews, community activity, site visits, custom CRM triggers) and routes ranked leads to the right rep by territory.
2. Duo Copywriter drafts personalized, multichannel outreach (email, LinkedIn, calls, WhatsApp) from that signal context.
3. A rep reviews, edits, sends, or dismisses each draft. Nothing sends automatically without a human in the loop.
4. Mailbox rotation spreads sending volume for deliverability, and the system learns from which drafts get edited, sent as-is, or dismissed to improve future recommendations.

## Who it's for

- B2B sales teams that want prospecting data, multichannel sequencing, and AI signal-detection bundled in one platform instead of assembling a stack from separate tools
- Teams that want an AI copilot drafting and prioritizing outreach for a human rep to approve, rather than a fully autonomous agent sending without review
- Sales orgs already running Salesforce or HubSpot who want native two-way CRM sync plus a Chrome extension for LinkedIn/Sales Navigator prospecting

## Strengths and weaknesses

- ✓ Bundles contact data (200M+ verified contacts), multichannel sequencing, and AI signal detection into one platform, rather than a data-only layer teams build engagement on top of themselves.
- ✓ Deliberately keeps a human reviewing, editing, or dismissing every Duo-drafted action before it sends, rather than sending autonomously without approval.
- ✓ A large, strongly positive third-party review base on G2 and a 2024 Gartner Cool Vendor recognition in Generative AI for Sales, one of five vendors named.
- ✓ Recently exposed prospecting, research, and outreach actions through a Model Context Protocol server for Claude and ChatGPT, so reps can drive Duo from inside an external AI assistant rather than only from Amplemarket's own UI.
- ✗ Only the entry Startup tier ($600/month, 2 seats) has a published price. Growth and Elite are both custom-quoted, so a growing team cannot model cost past two seats without a sales call.
- ✗ The company's own pages still disagree on Startup-tier credit numbers. The live pricing page states 13,500 email credits per seat per year and 600 phone credits per seat per year. The Amplemarket pricing blog states 15,000 email credits and 480 phone credits for the same tier. This listing carries both so a buyer can see the range.
- ✗ "Missing features" is the single most common complaint in G2 reviews, and reviewers flag contact-data accuracy as a recurring weak point despite the platform's claimed under 3% bounce rate.
- ✗ Total disclosed funding ($12M, last announced April 2022) is small next to several category peers, and no funding round has been publicly announced since. A real question for buyers weighing long-term vendor stability against better-capitalized rivals.
- ⚠ Not a fully autonomous send agent. Every Duo-drafted message requires a rep to review, edit, send, or dismiss it, so it does not replace headcount the way a fully autonomous AI SDR is pitched to.
- ⚠ Published, self-serve pricing stops at the 2-seat Startup tier. Any team beyond that negotiates a custom Growth or Elite quote.
- ⚠ Duo Inbox, the AI-assisted reply handling layer, is bundled into Elite only. On Growth it is sold as an add-on, so a team on Growth that wants unified inbox automation pays extra.

## Key features

- **Duo Copilot signal detection** — Monitors 100+ buying-intent signals daily (job changes, competitor-review mentions, community activity, website visits, custom CRM signals) and routes ranked leads to the right rep.
- **Duo Copywriter** — Drafts hyper-personalized first-touch and follow-up messages from signal context, across email, LinkedIn, calls, and WhatsApp. A rep approves before sending.
- **Duo Voice** — AI-assisted outbound calling, included from the Growth tier.
- **Duo Inbox** — AI-assisted reply handling in a unified conversation view. Included from the Elite tier and available as a paid add-on on Growth.
- **MCP server for Claude and ChatGPT** — Exposes prospecting, research, and outreach actions to a model context protocol client, so reps can run Duo actions from inside an AI assistant.
- **Built-in contact database** — 200M+ verified contacts with a claimed under 3% bounce rate and 96.5% phone-number accuracy. Bundled rather than sourced from a separate data vendor.
- **Job Change Alerts** — Tracked contacts who have moved to a new role. Bundled in tiers of 500 (Startup), 1,000 (Growth), and 2,000 (Elite).
- **Mailbox rotation and deliverability tooling** — Distributes sending volume across mailboxes to protect domain reputation. Includes email warmup, domain health center, spam checker, inbox placement testing, and mailbox recommendation on Growth and Elite.
- **Native Salesforce and HubSpot sync** — Two-way field-mapped sync with automatic activity logging. Chrome extension for LinkedIn/Sales Navigator prospecting. REST API and 8,000+ apps via Zapier.

## Use cases

- **Prioritizing outbound around real buying signals** — A rep's daily queue is ranked by Duo's signal detection instead of a static account list, so time goes to accounts actively showing intent.
- **Drafting outreach at volume without losing the human review step** — Duo Copywriter drafts personalized messages for every ranked lead. The rep still reads, edits, or approves each one before it sends, rather than trusting a fully autonomous send.
