Pricing

  • Pricing model: Primarily a monthly retainer for done-for-you outbound/appointment setting, with some fixed-scope sprint engagements; positioning is outcome-aligned and meeting-focused rather than seat-based. Older/public package pages also show fixed-price outreach packages.
  • Starting price: $1,000+ project minimum
  • Typical range: $1,950–$4,500 per outreach package
  • Billing: Monthly retainer is the main current model; fixed-window sprints are also offered. Older/public package pricing shows one-time/fixed package pricing for 90- to 180-day outreach packages, and directories also list hourly bands (<$25/hr, <$30/hr, or $50–$99/hr depending on source).
  • Contract terms: Current site says there are no long lock-ins; they work on monthly retainers or fixed-window sprints. An older package page shows campaign durations of 90 days and 180 days depending on package.
  • Guarantee: The older public pricing page says packages are designed to deliver measurable ROI with guaranteed qualified meetings on your calendar. TechBehemoths also lists the company value as "100% ROI ensured," but that appears to be directory/profile text rather than a clearly stated contractual guarantee.

What's included

  • Dedicated team running outbound end to end
  • AI research on every lead
  • Personalized messaging per prospect
  • Reply handling and qualification
  • Meeting booking / appointment setting
  • Weekly reporting and standing call
  • Direct Slack access
  • LinkedIn outreach
  • Cold email
  • In some packages, cold calling and dedicated SDR support

Prospect Engine now appears to sell mostly via custom quotes: its current pricing page says most engagements are monthly retainers and some are fixed-scope sprints, with scope and pricing determined on a call. However, I did find older/public package pricing on Prospect Engine's own pricing page showing three outreach packages at $1,950, $3,600, and $4,500 for 90- or 180-day campaigns, plus $150 add-ons. Directory figures from Clutch, GoodFirms, and TechBehemoths should be treated as third-party profile data or estimates, not authoritative agency-published price cards; they do corroborate that Prospect Engine is sold as an agency service with project minimums and/or hourly bands, but the strongest evidence for concrete pricing is the agency's own pricing page.

Process

How Prospect Engine actually works, reconstructed from customer reviews and third-party write-ups.

Prospect Engine appears to run a done-for-you B2B outbound engagement that starts with a strategy call and ICP definition, then moves into AI-assisted lead research, human-reviewed personalized outreach, reply handling/qualification, and meeting booking, with weekly reporting and direct client access. Review evidence is thin, but what exists supports an agency-led service with active support rather than a self-serve tool.

  1. 1

    Start with a strategy call and scope the outbound motion

    The engagement begins with a strategy call where Prospect Engine says it covers the client's ICP, offer, and how it would book meetings. Its site also says it scopes the details and pricing on a call rather than handing off a self-serve tool.

  2. 2

    Define the ICP and targeting criteria

    After kickoff, they define exactly who is worth reaching, and their site frames this as the first formal process step. Their materials also say the team keeps refining the target profile based on who actually replies.

  3. 3

    Research each lead with AI before outreach

    Prospect Engine says it researches every lead individually using AI, looking at signals like hiring, funding, tech stack, profiles, and recent posts rather than relying on scraped bulk lists alone. The service pages describe this research stage as the basis for outbound targeting.

  4. 4

    Draft personalized outreach and review it with humans

    The company says AI drafts messages from the prospect context, then a human edits and sends them at a natural pace. Its site repeatedly emphasizes per-prospect personalization and human judgment instead of templates or spammy automation.

  5. 5

    Run outreach, handle replies, and qualify next actions

    Once messages are live, Prospect Engine works incoming replies, classifies them, and decides the next step such as booking a call, answering, or exiting. The site describes reply handling and qualification as included in both engagement models.

  6. 6

    Book meetings and deliver proposals/follow-up support

    Qualified meetings are booked onto the client's calendar, with the client taking the calls while the agency runs the outbound engine. One service page also says call transcripts can be turned into branded proposals, indicating support extends beyond first response into sales follow-up materials.

  7. 7

    Report weekly and iterate with the client

    Prospect Engine says engagements include weekly reporting, a standing call, and direct Slack access to the team. Review evidence, while limited, also points to an involved team experience, with one customer praising the team as professional, caring, and focused on getting the best results, while another complained that a portal stopped working during a three-month campaign.
