Prospect Database
300M+ verified B2B contacts — your AI SDR's starting point
Every SalesDeveloper sequence begins with the right prospect. Our 300M+ contact database with real-time email verification, 40+ filter dimensions, and technographic overlays means your AI SDR starts with a targeted list — not a raw export that needs cleaning before it can be used.
Prospecting Funnel — ICP to Sequence-Ready
The Problem
A CSV export from Apollo is not a prospecting strategy
Most outbound teams start with a contact database as a static list-building tool: filter by title and industry, export a CSV, clean it manually, upload to the sequence tool. By the time the first email sends, 15–20% of the email addresses have already gone stale. The "technographic" filter is based on crawled data that's months old. The seniority filter captures the job title but not the actual decision- making authority.
SalesDeveloper's prospect database is not a standalone data tool. It's a live layer that sits inside the AI SDR Agent's discovery process — continuously queried, continuously verified, and continuously enriched with intent signals. The agent doesn't export a list. It sources a prioritized set of prospects, verified at the moment of outreach, with enough enrichment to drive genuine personalization from the very first touch.
How It Works
From 300M contacts to a sequence-ready prospect list in minutes
The AI SDR Agent queries the database continuously — not in batch exports. Here's how a prospect moves from raw contact to verified, intent-enriched, sequence-ready.
ICP-Driven Initial Filter
The agent applies your ICP criteria as the first filter layer: industry classification, company size range (by employee count and estimated revenue), geographic market, company age and growth stage, and job title patterns at the target seniority level. This filter reduces the 300M+ database to a set of candidates that demographically match your target market before any enrichment runs.
Technographic Overlay
Technographic data tells you what software each company is actually running — not what they claim to run in a press release. SalesDeveloper's technographic layer maps active tool usage across categories including CRM, marketing automation, data warehouse, messaging, support, analytics, and HR systems. This layer enables precision targeting based on the tech stack context your product fits into or replaces.
Real-Time Email Verification
Every email address is verified at the moment the prospect enters an active sequence — not at the time of list export. SalesDeveloper performs SMTP validation, MX record checking, and domain health verification in real time. Invalid addresses are suppressed before a single send is attempted. This is why SalesDeveloper achieves 97% deliverability rather than the 80–85% typical of database exports used without re-verification.
Intent Signal Enrichment
After passing demographic and technographic filters, each prospect is cross-referenced against SalesDeveloper's intent data layer: web research activity (visiting competitor pages or G2/Capterra), hiring signals (job postings that indicate a new initiative), recent funding events, executive changes, and tech stack churn signals. Prospects with active intent signals surface to the top of the sequence queue and receive first-touch outreach within hours of signal detection.
CRM Deduplication and DNC Compliance
Before any prospect enters an active sequence, SalesDeveloper checks your connected CRM for existing contact records, open opportunities, active accounts, and suppression lists. Contacts in open pipeline or who have unsubscribed from any previous outreach are automatically excluded. DNC compliance is enforced globally — a contact suppressed in one sequence is suppressed across all active sequences immediately.
Database Capabilities
Every filter dimension your AI SDR needs to find the right prospect
40+ Filter Dimensions
Industry classification, company size, revenue band, geographic market, growth stage, tech stack composition, hiring velocity, funding recency, employee growth rate, department size ratios, executive tenure, and 30+ additional firmographic and behavioral dimensions.
Real-Time Email Verification
97% email deliverability starts with verification that happens at outreach time, not at list-build time. SMTP validation, domain health checks, and catch-all detection run for every contact before the first send — protecting your sender reputation and your sequence performance metrics.
Technographic Intelligence
Know what tools each target company is running before you write the first word. Technographic data maps active software usage across 30+ categories, enabling messaging that speaks to the specific integration, replacement, or complement scenario your product addresses.
Hiring Velocity as a Buying Signal
Companies that are growing headcount in a specific function are signaling investment in that area. SalesDeveloper tracks hiring velocity per department and surfaces prospects who are actively building the team that would use your product — before they've finalized vendor selection.
Funding-Stage Filtering
A seed-stage company and a Series C company need completely different outreach — different value propositions, different price points, different champion targets. SalesDeveloper filters by funding stage, recency of raise, and estimated burn runway to ensure your messaging matches the prospect's actual budget context.
Continuous Database Refresh
Contacts in your active prospect pool are refreshed automatically. Job changes are detected and sequences are paused for contacts who have left the company. New contacts joining target accounts are surfaced and added to the prospecting queue without manual list maintenance.

In Practice
Finding the exact right 500 companies in under 10 minutes
A revenue operations platform wants to target VP-level and above contacts at B2B SaaS companies with 50–500 employees that are currently running Salesforce as their CRM, have raised Series A or B funding in the past 18 months, and are actively hiring RevOps or Sales Ops roles — a signal that they are actively building the function that would use the product.
That query runs in under 60 seconds and returns 487 contacts. Every email address is verified in real time. Every contact is cross-referenced against the customer's CRM to remove existing accounts. Intent signals flag 31 of the 487 as high-priority — they're actively researching RevOps tools based on G2 traffic data. Those 31 get first-touch within the next two hours. The remaining 456 enter a scheduled sequence queue. Total time from ICP definition to first send: under 15 minutes.
