B2B Sales has a big inefficiency problem

01

Success costs more than it should

The B2B industry spends over $1.2 trillion annually on go-to-market efforts, but much of this is wasted through poor lead prioritisation and engagement.

02

98% of sales efforts fail to convert 

Conversion rates are abysmally low, putting pressure on the 2% of deals that materialise to justify the investment wasted on the other 98%.meaningful and enjoyable.

03

Serendipity is not a sound strategy

Current sales techniques rely heavily on chance encounters with leads who are ready to transact, creating an inefficient process with a high rate of failure.

Other ‘solutions’ are making things worse

They don’t know what they don’t know

AI tools are only as useful as the data they consume – most of which is limited to internal enterprise CRM systems and out of date from the moment it’s published.

Turning up the noise

Automation tools push sales teams into the quantity-over-quality trap, without enabling the relevance and personalisation needed for successful results.

Failing the ‘so what?’ test

Customer intelligence tools package a whole lot of information, but leave sales professionals flailing with the million-dollar question: what should I do next?
