B2B Prospecting Glossary

Intent Data

Behavioral signals that indicate a buyer is actively researching a purchase. Sources include content consumption, search activity, and review site visits. Intent data identifies in-market prospects before they self-identify.

SDR

Sales Development Representative. A role focused on outbound prospecting, cold outreach, and meeting qualification. SDRs generate pipeline by converting cold contacts into sales-qualified leads for account executives.

ICP

Ideal Customer Profile. A data-driven description of the company type most likely to buy, retain, and expand your product. Defined by firmographics, technographics, and behavioral signals. Precision ICP reduces churn and improves close rates.

ABM

Account-Based Marketing. A B2B strategy that targets specific high-value companies rather than broad audiences. Sales and marketing align on a defined account list. Outreach is personalized to each target account's context and buying signals.

ARR

Annual Recurring Revenue. The annualized value of subscription or recurring contract revenue. ARR is the primary health metric for SaaS and subscription businesses. Growth-stage companies use ARR to benchmark pipeline requirements.

MQL

Marketing Qualified Lead. A prospect that has met a defined engagement threshold — such as downloading content, attending a webinar, or visiting pricing pages — indicating readiness for sales outreach. MQL definitions vary by organization.

SQL

Sales Qualified Lead. A prospect that has been vetted by sales and confirmed to meet ICP criteria with active buying intent. SQLs are handed from SDRs to account executives for closing activity. SQL volume drives pipeline forecasts.

CPL

Cost Per Lead. Total spend divided by leads generated in a given period. CPL benchmarks vary by industry, channel, and lead quality. Verified direct-dial contacts typically lower CPL by reducing wasted outreach attempts.

Data Decay

The rate at which B2B contact data becomes inaccurate over time. Industry estimates place annual B2B data decay at 25–30%. Causes include job changes, company restructuring, and contact detail updates. Decayed data wastes dial capacity and skews pipeline models.

Direct Dial

A phone number that connects directly to an individual's desk or mobile device, bypassing gatekeepers and switchboards. Direct dials convert at 3x the rate of main-line numbers. Mobile direct dials are the highest-value contact asset in outbound prospecting.

RevOps

Revenue Operations. A function that aligns sales, marketing, and customer success under unified data, process, and technology infrastructure. RevOps eliminates handoff friction and creates a single revenue accountability structure across the GTM team.

CRM

Customer Relationship Management. Software that stores and manages all prospect and customer interaction data. CRMs are the central revenue record. Data quality inside the CRM directly determines pipeline accuracy and forecasting reliability.

Series A

The first significant institutional venture capital funding round, typically ranging from $2M to $15M. Series A signals product-market fit and triggers rapid go-to-market scaling. Pipeline infrastructure must be established within 90 days of close.

Sales Velocity

A formula measuring pipeline revenue generation speed: (Number of Deals × Average Deal Value × Win Rate) ÷ Sales Cycle Length. Increasing any variable accelerates revenue output. Data quality directly impacts win rate and cycle length.

ZoomInfo

A B2B contact and company intelligence platform providing verified emails, direct dials, firmographic data, and intent signals. ZoomInfo is one of the largest commercial B2B data providers. Contact accuracy and database freshness vary by segment and geography.

Apollo

Apollo.io is a B2B sales intelligence and engagement platform. It provides contact data, sequencing tools, and analytics for outbound sales teams. Apollo targets SMB and mid-market revenue teams with a self-serve data model at lower price points than enterprise alternatives.

Bi-Directional Sync

A data integration architecture where two systems — typically a CRM and a data enrichment or marketing platform — exchange updates in both directions in real time. Bi-directional sync prevents contact records from drifting out of alignment as either system is updated.

GDPR

General Data Protection Regulation. EU regulation governing how organizations collect, store, and process personal data of EU residents. GDPR requires lawful basis for processing, explicit consent where required, and the right to erasure. Violations carry fines up to 4% of global annual revenue.

CCPA

California Consumer Privacy Act. U.S. state law granting California residents rights over their personal data, including the right to know, delete, and opt out of data sale. CCPA applies to businesses meeting revenue or data volume thresholds. Enforcement is handled by the California Attorney General.

CAN-SPAM

Controlling the Assault of Non-Solicited Pornography And Marketing Act. U.S. federal law regulating commercial email. Requirements include a valid physical address, clear opt-out mechanism, and no deceptive subject lines. Penalties reach $51,744 per violation.

Marietta, GA

A city in Cobb County, Georgia, northwest of Atlanta along the I-75 corridor. Marietta is a growing technology and professional services hub inside Georgia's Silicon Peach Corridor. Phone Number Leads is headquartered here.

Silicon Peach

A colloquial term for Georgia's technology corridor, stretching from Atlanta through Cobb County and beyond. The Silicon Peach Corridor hosts a concentration of SaaS companies, fintech firms, cybersecurity operations, and B2B technology vendors along the I-75 tech hub axis.
