A lead is a person or organisation that has expressed interest in your product or service through some voluntary action—downloading content, filling a form, attending a webinar, requesting a demo, or engaging with your website beyond casual browsing. This interest signal distinguishes leads from the broader universe of potential customers who may fit your ideal customer profile but haven't yet raised their hand. Leads exist in various qualification states: raw leads (anyone who provided contact details), marketing-qualified leads (leads meeting specific engagement or fit criteria), and sales-qualified leads (leads vetted by sales as worthy of direct pursuit). The lead concept emerged from direct marketing traditions where response rates determined campaign success; modern B2B marketing has refined the definition to focus on intent signals rather than mere contact acquisition. Lead databases form the raw material for nurture campaigns, pipeline forecasting, and revenue planning.
Leads matter because they represent the pool of potential future customers who've opted into your marketing, making them legally contactable and demonstrably interested in your category or solution. Without a systematic approach to capturing, tracking, and progressing leads, your marketing efforts generate unmeasurable activity rather than quantifiable pipeline contribution. For B2B organisations especially, where buyers research extensively before engaging sales, lead capture mechanisms (gated content, demo forms, email subscriptions) ensure you don't lose prospects who are months away from purchase readiness. The distinction between lead types prevents waste: sales teams closing low-quality leads produce terrible conversion rates and demoralize the team, whilst high-quality leads sitting uncontacted in marketing databases represent pure lost opportunity. Lead metrics—volume, quality, source, cost per lead—also provide crucial feedback on channel effectiveness, helping you allocate budget to acquisition tactics that produce viable prospects. Organisations tracking lead progression through defined stages report 50% shorter sales cycles because systematic qualification and nurture prepare leads properly before sales engagement. The lead framework also creates accountability: marketing owns lead generation and initial qualification; sales owns lead conversion. This handoff clarity reduces the finger-pointing that paralyses growth when results disappoint.
A lead is a person or organisation whose contact details you lawfully hold and who has shown some level of interest in your expertise—however slight. That interest might be downloading a white paper, requesting a pricing sheet, or handing over a business card at a trade-show. What matters is that the individual performed an intentional action and left a trace you can follow up. Simply scraping addresses from the internet, buying a list, or counting anonymous page views does not create leads; those records lack consent, context and genuine engagement. In my own practice I define a lead as “a known name, firm, and at least one direct channel—email or phone—acquired through an opt-in or legitimate interest event.”
HubSpot creates a contact record the moment an email is captured and tags it Lead by default.
Pipedrive inserts new people or organisations as Leads in the Lead Inbox before they graduate to Deals.
Key concepts and frameworks explained clearly. Quick reference when you need to understand a term, refresh your knowledge, or share with your team.
Install clear opt-in forms, gated assets and event scanners that require deliberate action from the prospect. Resist the lure of purchased databases; they inflate list size while eroding engagement and deliverability.
Within minutes of capture, append company size, industry and role through an enrichment service like Cognism. Fast enrichment allows instant routing rules—enterprise prospects may flow to senior account directors, while start-ups enter an automated nurture track.
Record the first meaningful touch—not simply “website”—so you know whether the original magnet was a podcast mention, a referral webinar, or a paid-search ad. Source clarity proves which magnets genuinely attract your ICP.
Apply a lightweight points system: industry match, seniority, company size and recent actions such as webinar attendance. Leads above a threshold escalate to Marketing-Qualified Lead status; those below enter a longer nurture programme.
Create a service-level agreement: sales commits to contact new leads within, say, 24 business hours. Marketing, for its part, promises that each record meets baseline qualification fields. The SLA closes the loop and converts “leads generated” into “leads worked.”
A robust lead process—intentional capture, immediate enrichment, accurate tagging, sensible scoring and timely hand-off—turns raw interest into an orderly queue for nurturing and qualification, setting the stage for the deeper stages of MQL and SQL that follow in the revenue engine.

Most B2B marketers are either Random Ricks (trying everything) or Specialist Steves (obsessed with one channel). Generalists run tactics without strategy. Specialists hit channel ceilings. But there's a better way.

Tries everything at once. Posts on LinkedIn, runs ads, tweaks the website, chases referrals. Nothing compounds because nothing's consistent. Growth feels chaotic.

Obsessed with one tactic. 'We just need better ads' or 'SEO will fix everything.' Ignores the rest of the system. One strong engine can't carry a broken machine.
