# Introducing The Prospector: An AI Agent That Builds Audiences From Your CRM | Synter > Source: https://synterai.com/blog/prospector-agent-audience-builder > Cached: 2026-10-09T01:10:59.762Z > Words: 995 --- [Skip to app content](#global-agent-app-surface)[Skip to main content](#main-content)[Back to Research & Articles](https://synterai.com/blog)## The problem with interest targeting Most ad accounts default to interest-based audiences because they are the path of least resistance: pick a few keywords, let the platform infer, run the campaign. The platform happily delivers impressions. The CPA looks fine for a week. Then it drifts. Interest audiences are a guess about who you should be talking to. They are downstream of a platform's behavioral model — which is tuned for the platform's revenue, not your CAC. Every serious B2B and high-consideration B2C account we work with eventually hits the same ceiling: interest targeting cannot match the performance of audiences built from your own data. ## What The Prospector does The Prospector is a Synter agent persona built for one job: **turn first-party data into precisely-targeted ad audiences and sync them to every platform you care about.** - **CRM segments → audiences.** Pull a HubSpot, Attio, or Salesforce segment and push it to Google Customer Match, Meta Custom Audiences, LinkedIn Matched, Reddit, X Tailored, TikTok Custom Audiences, and Microsoft Ads — hashed, deduplicated, and consent-aware. - **Lookalikes from your best customers.** Take a seed list of paying customers (or a high-LTV cohort) and build a lookalike audience on every platform that supports it. Skip Reddit lookalikes — they are weak — and target communities instead. - **Signal-based audiences.** Build audiences from real buying signals: hiring, funding, ad-spend changes, tech installs, intent data. WattData clusters feed in directly so you can target "RevOps leaders at B2B SaaS companies that just raised a Series B." - **UTM and attribution hygiene.** Ensures Attio (or your connected CRM) actually has the UTM attributes to receive campaign attribution back. No more "we ran the ad but the leads don't have a source." Spawn it with one mention In any Campaign IDE thread, type `@Prospector` and ask: - *"Build a lookalike audience on Meta and LinkedIn from our top 100 customers by revenue."* - *"Find RevOps leaders at B2B SaaS companies that hired a growth marketer in the last 30 days and push them to LinkedIn Ads."* - *"Sync our Attio "Qualified Pipeline" list to Google Customer Match and Meta as suppression audiences."* ## Where it fits in the Synter agent team Enrolled workspaces only The full named-agent team (@Strategist, @Analyst, @Builder, @Optimizer, @Creative, @Prospector) is available exclusively to enrolled workspaces. The default Campaign IDE chat works for everyone — but spawning specialist agents by mention requires enrollment. The Prospector joins a team of expert agents you can summon by mention in any campaign thread. Each one specializes — and each one knows when to hand off. - **@Strategist** — senior advisor. Recommends bidding strategy, channel mix, and account structure. - **@Analyst** — deep performance analysis, attribution, statistical rigor. - **@Builder** — campaign structure, setup, tracking preflight, launch. - **@Optimizer** — budget allocation, bid adjustments, day-parting, pacing. - **@Creative** — ad copy, creative briefs, platform-compliant variants. - **@Prospector** — audience building from CRM, signals, and lookalikes (new). Each agent has its own tool patterns and skill set. The Prospector knows how to use `build_lookalike_audience`, `sync_audience`, `find_audience_signals`, and the platform-specific audience-sync APIs — and it knows to hand off to @Builder or @Creative once the audience is live. ## Boundaries: what The Prospector does NOT do We are deliberate about scope. The Prospector **builds and activates audiences for paid media**. It does not: - Send outbound emails or LinkedIn messages — that lives in **Synter Outbound**, a separate product. Build the audience here, activate via paid media or hand off to Outbound for sequenced touches. - Create campaigns or generate creative — hand off to @Builder or @Creative. - Sync PII-rich audiences to platforms that do not support hashed matching. GDPR and CCPA are non-negotiable. ## Why enrollment is required The Prospector ships to enrolled workspaces first because audience syncing crosses platform-specific quirks (Meta's CAPI hashing rules, LinkedIn's Matched Audience minimums, Google's Customer Match policy gates, Reddit's segment limits) and we want to learn from real customer accounts before opening it to every workspace. Enrolled workspaces also get: - Autonomous agents (always-on optimization & alerts) - Per-user MCP servers (Claude Desktop / Cursor / Amp) - ChatGPT Ads (sponsored responses in ChatGPT) - New ad platforms as we build them: Walmart Connect, Criteo, and more - AI image and video generation - 5,000 bonus credits per month - **Weekly private chat with the founder** Apply in [workspace settings](https://synterai.com/settings/crucible).
