6sense Research: 82% of B2B Buyers Choose Their Pre-Contact Favorite

B2B purchasing decisions are often shaped long before vendors receive an inquiry or enter a formal sales evaluation. According to 6sense's 2026 Global B2B Buyer Experience Report, buyers select the vendor they already favor before contacting a seller 82% of the time. Based on a survey of 4,611 recent B2B buyers across North America, APAC, Continental Europe, and the UK and Ireland, the research highlights the importance of brand familiarity, early-stage demand generation and buyer preferences formed between purchasing cycles.

B2B vendors may be entering the sales conversation later than they think. New research from 6sense suggests that much of the purchasing decision is already taking shape before buyers contact a sales representative, with the vendor preferred before seller engagement ultimately winning 82% of the time.

The findings come from 6sense's 2026 Global B2B Buyer Experience Report, which surveyed 4,611 recent B2B buyers across North America, Asia-Pacific, Continental Europe, and the UK and Ireland. The annual study examines how buying groups research vendors, develop preferences and move through purchasing decisions.

Its central finding challenges the traditional view of the B2B sales funnel: the buying journey does not begin when a prospect enters an active evaluation. Buyers continue monitoring vendors and solutions between purchasing cycles, meaning brand perception and vendor preference can develop well before a sales opportunity becomes visible.

Vendor Preferences Form Between Buying Cycles

The report found that 96% of buyers stay informed about vendors and solutions between purchases. Vendor websites were the most frequently cited information source, used by 36% of respondents.

That ongoing research can influence future purchasing decisions. Seventy-one percent of buyers said their views of vendors changed somewhat or significantly between evaluation cycles.

By the time a buying group forms, 73% already have preferences for at least two vendors. The eventual winner appears on the initial shortlist 92% of the time.

These findings suggest that vendor selection is often shaped by accumulated familiarity and previous research rather than a fresh comparison initiated by a sales team. The report also notes that buyers have completed six to eight previous evaluation cycles in relevant solution categories, reinforcing the importance of sustained visibility.

For B2B marketing teams, this shifts the emphasis toward maintaining a credible presence between active buying periods. Content, product information, customer evidence and ongoing brand engagement can influence whether a company is considered when a new purchasing requirement emerges.

LLMs Influence Evaluation More Than Vendor Discovery

Generative AI is becoming part of B2B research, but the report suggests its role is more concentrated in evaluation than initial vendor discovery.

Eighty-one percent of buyers said they used a large language model (LLM) somewhere during an evaluation, down from 94% in the previous year's study. However, only 26% used LLMs to discover vendors.

Before contacting a seller, 21% cited LLMs as an influence on their view of vendors. Existing knowledge was cited by 34%, while internal discussions influenced 32%.

The distinction matters for companies investing in generative engine optimisation (GEO) and AI search visibility. AI platforms are becoming part of how buyers summarise, compare and validate information, but they are not yet the dominant source of new vendor discovery in this survey.

Marketing strategies therefore need to account for both established discovery channels and AI-assisted research, rather than treating LLM visibility as a replacement for brand awareness and direct buyer engagement.

Sales Conversations Often Begin During Validation

The report estimates an average B2B buying cycle of 10.3 months, with buying groups spending approximately 60% of that period in the selection phase before contacting a seller.

During this stage, buyers determine whether a category warrants investment and which vendor they prefer. More than half of respondents (56%) said justifying the category was as difficult as, or more difficult than, choosing a vendor.

Once buyers contact sellers and enter the validation phase, the preferred vendor wins 82% of the time, according to the study.

6sense Head of Research and Thought Leadership Kerry Cunningham said the sales cycle commonly understood by revenue teams is often the validation stage of a selection process that has already been underway for multiple quarters.

The findings also connect evaluation triggers with outcomes. Advances in available technology were the most common reason for starting an evaluation, cited in 39% of cases. Internal growth needs appeared in 34% of evaluations that resulted in a purchase, compared with 19% of those that stalled or were abandoned. Dissatisfaction with an existing solution showed the reverse pattern, appearing in 11% of completed purchases and 22% of stalled or abandoned evaluations.

For revenue teams, the implication is that demand generation, brand building and buyer education need to begin well before a prospect signals active purchasing intent. Marketing and sales operations must account for the longer period in which buying groups form preferences and justify investment.

Market Landscape

B2B buying increasingly involves multiple stakeholders, extended research periods and a mix of information sources. This makes the visible sales pipeline an incomplete picture of how demand develops.

The 6sense findings highlight the role of brand familiarity, vendor websites, internal discussions and AI-assisted research in shaping preferences before sales engagement. They also suggest that LLM adoption does not necessarily translate into widespread AI-led vendor discovery.

For marketing and revenue technology providers, the findings reinforce the need to connect brand awareness, content strategy, account engagement and sales intelligence across the full buying cycle.

Strategic Outlook

B2B organisations may need to rethink how they measure marketing's contribution to revenue. Lead volume and seller-contact activity capture only part of the journey if buyers have already developed preferences before entering a measurable sales process.

Marketing teams should focus on sustained visibility, clear product information, category education and credible evidence that supports buyer evaluation. GEO and AI search strategies can contribute to this effort, but they should complement established brand and content programmes.

The data also points to an opportunity for closer alignment between marketing, sales and product teams. Understanding why buyers initiate evaluations, what makes category investment difficult and how preferences change between cycles can help organisations address demand earlier.
