Synter Prospector Is Now Generally Available

Modern B2B growth teams have been forced to stitch together a fragile 5-tool stack just to run outbound campaigns. Today, Synter Prospector is Generally Available — bringing waterfall discovery, dedicated secondary domain deliverability, and 27-platform ad synchronization into a single governed execution platform.

The Problem: Modern Outbound Stack Sprawl

For the past three years, running outbound growth has required stitching together a complex, fragile assembly line of disconnected point solutions:

  • Enrichment engines (Clay, ZoomInfo) running $300 to $1,500+/month with convoluted formula columns and cascading credit usage.
  • Static contact databases (Apollo, Lusha) plagued with decaying job titles and stale verification tags.
  • Third-party sequencers (Smartlead, Instantly) requiring fragile webhook connectors and external Zapier bridges.
  • Standalone warmup services and manual DNS record provisioning.
  • Manual CSV exports uploaded by hand into LinkedIn Campaign Manager, Meta Ads Manager, and Google Ads.

Beyond the $2,000+ monthly software bill, engineering and growth teams waste hours debugging broken webhook payloads, resolving CSV schema mismatches, and monitoring domain reputation degradation. Synter Prospector replaces this entire stack with a single native execution engine.

Strict Secondary Domain Isolation Standard

Step-by-Step Architecture

Prospector operates as a closed-loop execution system connecting prospect intelligence directly to ad channel activation:

                                         (LinkedIn, Meta, Google, X, etc.)

1. Signal-Driven Waterfall Discovery

Prospector evaluates real-time signals — including live tech stack detections (via BuiltWith), active hiring patterns, and verified demographics — querying cascading providers on demand so data is never stale.

2. Dedicated Domain Deliverability

Inboxes are provisioned on dedicated secondary domains with automated warmup schedules, DKIM/SPF rotation, and 301 web traffic pass-through to your primary website.

3. Contextual Sequencing

Deliver zero-fluff, hyper-relevant technical messaging. Prospector handles automated out-of-office rescheduling, positive reply routing, and meeting scheduling automatically.

4. 27-Platform Audience Synchronization

High-priority accounts and engaged leads are instantly staged as custom audiences across 27 ad platforms (LinkedIn, Meta, Google, X, Reddit, etc.), surrounding decision-makers with relevant ad creative.

Developer & MCP Integration

Prospector is fully programmable. Agents and developer workflows can discover prospects, inspect pipeline health, and stage audience artifacts directly through Synter MCP tools:

// Triggering waterfall discovery & qualification via Synter MCP
const leads = await mcp.call("growth_run_pipeline", {
  query: "VP of Engineering or Head of Growth",
  technology_filters: ["segment", "google_tag_manager", "posthog"],
  headcount_range: "50-500",
  verified_email_only: true,
  max_records: 250
});

// Stage qualified accounts directly into cross-platform custom audiences
await mcp.call("stage_audience_artifact", {
  audience_name: "Q3 High-Intent Engineering Leads",
  platforms: ["LINKEDIN", "META", "GOOGLE", "X"],
  sync_frequency: "REALTIME"
});

Domain isolation and DNS records are verified automatically on every provisioning run:

// Automated dedicated secondary domain provisioning with strict authentication
{
  "domain": "trybrand.com",
  "root_redirect_target": "https://brand.com?utm_source=prospector",
  "dns_records": [
    { "type": "TXT", "host": "@", "value": "v=spf1 include:_spf.domain.com ~all" },
    { "type": "TXT", "host": "synter._domainkey", "value": "v=DKIM1; k=rsa; p=MIGfMA0GCSqGSI..." },
    { "type": "TXT", "host": "_dmarc", "value": "v=DMARC1; p=reject; rua=mailto:dmarc@trybrand.com" }
  ],
  "inbox_warmup_status": "WARMED_ACTIVE",
  "daily_send_cap_per_inbox": 45
}
