Guillaume Burstert
Founder & CEO, Sunwise · LinkedIn as a commercial engine
Guillaume runs Sunwise, delivering mobile solar energy systems to off-grid communities and businesses across Africa and the Middle East. He does not treat LinkedIn as a side activity: it is his prospecting engine, a fully digital sales funnel that drives visibility, trust and leads for a company selling hard infrastructure.
His content has passed three million impressions, but the number he cares about is the conversations it starts with decision-makers. What he teaches is that mechanism — storytelling and technical credibility used deliberately, in a market where nobody buys on impulse.
