David Sinclair-Black

Hey there! I’m David Sinclair-Black, Founder, BuiltDiffernt, a revenue engineering firm focused on designing and operating end-to-end pipeline systems for B2B companies.

Rather than treating lead generation as a volume game, I specialise in building signal-based outbound systems that combine messaging, data, and timing to generate high-quality, attributable opportunities.

My approach blends behavioural science with structured execution, ensuring campaigns don’t just create activity, but drive meaningful commercial outcomes.

BuiltDiffernt works with Series B+ startups, mid-sized businesses, and enterprise teams looking to move beyond fragmented outbound efforts and into scalable, repeatable pipeline systems.
