Why is lead generation the foundation of B2B SaaS growth?
B2B (business-to-business) lead generation is the process of acquiring potential customers, companies or decision-makers who may be interested in your business's offerings. In 2024 and 2025, it will become one of the key growth areas for technology companies. According to the report, HubSpot State of Marketing 2025, as many as 57% of B2B companies have increased their investments in sales support technologies, and the customer acquisition cost (CAC) has increased on average by 34% over the last two years (HubSpot Report, 2025).

What is a lead?
Lead - A potential customer is a person or company who has shown interest in your offer, for example, by completing a form, signing up for a newsletter (Marketing Qualified Lead), or responding to a cold email (Sales Qualified Lead). In practice, there are three main types of leads:
- Cold lead- contact without prior interaction with the brand;
- Warm lead- a person who knows your brand or has had contact with it;
- Hot lead- potential customer ready for a sales conversation or purchase.
Thanks to modern technologies - such as CRMs (e.g.Pipedrive) and AI tools (e.g. Apollo, Clay) - it is possible to automatically track user behavior and assess their purchase readiness.
Where do leads come from?
There are many sources of B2B leads, but the most crucial channels are those that allow you to reach decision-makers with a specific message. The most effective channels in the technology industry are:
- LinkedIn - generates the highest quality leads thanks to precise targeting and the presence of decision-makers;
- Google Ads - effective in reaching people actively seeking solutions;
- Email outreach and ABM (Account-Based Marketing) - enable personalized communication;
- Industry events - still valuable for face-to-face interactions, especially supported by contact management tools.
In 2025, the importance of AI in marketing- 79% of B2B marketers already use artificial intelligence to personalize campaigns, score leads and support chatbots (HubSpot Report, 2025).

How to Choose Between These Channels
The section above lists four channels without saying how to pick one. Fourquestions settle it in most cases.
How big is the addressable market? Under a thousand companies, search hasnothing to work with, because that volume of people are not typing your probleminto Google. Outbound reaches all of them by name inside a month. Above a fewthousand, search starts to pay back.
Do buyers know the problem has a name? If they do, they search for it andinbound compounds. If you have to explain that the problem exists before you cansell the solution, nobody is searching, and outbound is the only channel thatworks without a year of education first.
How much trust is needed before a first call? High-trust purchases, such asanything touching payroll, security or regulated data, need proof beforeoutreach lands. That points to content, events and referrals carrying theopening, with outbound following.
Who will own it after the first month? A channel with no owner degradesfaster than one with a smaller budget and a name attached. This questiondisqualifies more channels than the other three combined.
How Many Leads You Actually Need?
Start at the revenue target and work backwards. A team that needs 600,000 in newbusiness, with an average deal of 20,000, needs thirty closed deals. At a 20%close rate from a first meeting, that is 150 meetings. At a 5% reply-to-meetingrate on outbound, that is 3,000 contacted companies over the year, or 250 amonth. Take every one of those numbers from your own CRM. Including these.
The exercise is useful even when the inputs are rough, because it usuallyproduces one of two answers. Either the number is reachable, in which case younow know the monthly volume and can size the list and the mailbox count againstit. Or the number is larger than your addressable market, which means no channelwill get you there and the problem sits upstream, in pricing, dealsize or segment.
That second outcome is common, and far cheaper to find in a spreadsheet thanafter two quarters of campaigns.
Quality or quantity of leads - what matters?
Just a few years ago, companies focused primarily on lead generation. Today, in a world of rising CAC costs( Customer Acquisition Cost), quality data from McKinsey 2024 B2B Pulse Survey show that effective B2B growth is based on building long-term relationships, personalization and partnerships instead of mass outbound campaigns (McKinsey 2024).
McKinsey emphasizes that:
- B2B buyers today use more than 10 channels in their purchasing process, requiring an integrated, multi-channel approach;
- 80% of them expect a high-quality omnichannel experience, lack of consistency causes loss of interest;
- Companies that personalise one-to-one communication are 1.7 times more likely to gain market share.
- The key to scalable growth is the quality of relationships in strategic partnerships, not the number of messages sent.
The conclusions are clear: in the era of data and AI, what matters is the depth of relationships, tailoring the offer to the customer's context and building trust in the long term.
How to qualify leads?
Lead qualification is a process that allows you to distinguish contacts with real purchasing potential from those that require further attention or are completely lost. Well-executed qualification is key to effective sales, allowing the sales team to save time and focus on the customers with the greatest potential.
In practice, this process involves both data analysis and sales conversations. Companies often combine several methods: from simple criteria such as industry, company size, or decision-making position, to more advanced scoring models based on user behavior online. For example, if a person visits an offer page several times a week or downloads educational materials, it can be assumed they are more ready for a sales contact.
Collaboration between marketing and sales teams is also playing an increasingly important role, with jointly establishing criteria that define when a lead is "ready" for a sales conversation. This eliminates friction and allows for a smooth transition of contacts along the sales funnel.
Consequently, the most effective organizations build a data-driven qualification system, but they don't forget about the human factor. Trust, industry context, and salespeople's intuition often play just as important a role as algorithms.
Why Lead Generation Fails?
Three failures account for most of it, and none of them is the channel.
The list describes who you want as customers rather than who you have. Ateam that has closed twelve deals with software houses builds a campaign aimedat enterprise SaaS, because that is where the ambition points. The market hasalready told them where they win, and the campaign ignores it. Read the closeddeals before writing the list.
Nobody owns it after the first month. The first campaign gets attentionbecause it is new. The second runs on a list nobody refreshed, from a domainnobody warmed, with copy nobody has looked at since launch. The mechanism israrely a decision to stop caring. It is that no name was attached to the work.
Volume is the number that gets reported, and replies are the one that matters.Reporting leads generated makes every channel look busy. Reporting replies, meetings and cost per meeting makesthe weak ones visible within a month. Teams that track volume tend to discover adead channel two quarters after it died.
What a Lead Costs, and How to Work It Out?
Cost per lead is the metric most teams report and the one that misleads themmost, because it stops at the wrong point in the funnel.
Take the full cost of the channel for a quarter, including tools, salaries andthe share of someone's time nobody logs. Divide by the leads it produced. Thendivide again by the proportion of those leads that reached a first meeting.That second number is the cost per meeting, and it is the one to compareacross channels.
The reason the first number misleads is that channels differ enormously in whatthey call a lead. A content download and a replied-to outbound message bothenter the CRM as one record. One of them is a person who wanted a template. Theother is a decision-maker who wrote back. Averaging them produces a figure thatlooks precise and decides nothing.
Two adjustments make the comparison fair. Spread the setup cost across the periodit serves, not the month it was paid, or an inbound channel looks ruinous inquarter one and free in quarter four. And split shared toolingproportionally, so it does not all land on whichever channel finance happens tobe reviewing.
The best lead qualification frameworks
Two frameworks cover most B2B situations, and the choice between them comes down to how many people have to agree before anyone signs.
Qualification and Scoring Are Not the Same Thing
The two get used interchangeably and describe different moments.
Scoring is a ranking that happens before anyone speaks to the lead. It runs onfields already in the CRM, it applies to every record at once, and it decideswho gets contacted first. Qualification happens during the conversation. It runson answers a person gives, it applies to one lead at a time, and it decideswhether to continue.
BANT and MEDDIC below are qualification frameworks. They need a conversation towork, because budget, authority and decision process are not fields you can buyfrom a data provider. Trying to score them from enrichment data producesconfident guesses about how someone runs their company, which is the fastest wayto write a message they will not answer.
The practical order is simple. Score to decide who to contact. Qualify to decidewho to keep talking to. For how the scoring half works in detail, see our guideto B2B lead scoring.
Your First Thirty Days
Four weeks, one channel, one hypothesis. Adding a second channel before thefirst produces an answer only means you will not know which one worked.
Week one. Pull every deal you closed in the last year and find what the goodones share. Not the ideal customer profile from the deck, the one visible in thedata. Company size, industry, the role that signed, and what changed at theirend shortly before they bought.
Week two. Build one list of no more than 200 companies matching thatprofile. Set up the infrastructure the channel needs, which for email meansseparate domains and a warm-up that will still be running when you send.
Week three. Contact the first fifty by hand. Not a sequence. Fifty messageswritten one at a time, so you find out which phrasing earns replies before youencode one of them permanently.
Week four. Count replies, not sends. If the segment answers, you have apattern to automate and a number to plan the next quarter against. If itdoes not, you have spent four weeks instead of two quarters finding out, and thenext hypothesis costs the same again.
Summary
Generating B2B leads isn't just about acquiring contacts, but above all, building relationships and understanding the needs of decision-makers. In 2025, an effective strategy combines AI, social selling and data into one coherent system.
Key conclusions:
- AI is a standard of modern B2B marketing;
- It counts quality, not the number of leads - each interaction should be personalized;
- LinkedIn remains one of the most effective channels for reaching decision-makers;
- CRM and automation are the pillar of scalability in the technology industry.
