Lingesh is genuinely one of the best trainers we have engaged in 15 years of running corporate programmes. His ability to connect with a room — whether it's 20 or 200 people — is extraordinary. Our clinical team came back energised and with concrete tools they actually use.
We brought Lingesh in for a leadership resilience programme during a particularly difficult restructuring period. The feedback from our managers was overwhelmingly positive. What sets him apart is that he understands business — he doesn't just motivate, he changes behaviour.
After Lingesh's CX programme, our service advisor scores jumped from 3.9 to 4.8 nationally. That's not a motivational talk result — that's a training result. He delivered something that actually moved the needle for our customers.
Our agency advisors are competitive, experienced, and hard to impress. Lingesh walked in and had the entire room on their feet within 20 minutes. The programme translated directly into improved prospecting discipline across the team. Highly recommended.
We engaged BigGuru for a 3-day national retail sales conference. Lingesh held the stage for 4 hours on day two and the energy never dropped. Our outlet managers left with a completely different mindset around customer engagement. Truly world-class delivery.
Lingesh trained our dealer network across Peninsula Malaysia — 150+ sales consultants over three months. The consistency of delivery, the cultural sensitivity, and the follow-through support were all exceptional. We'll be re-engaging him next quarter.
Whether you need a 60-minute keynote or a 3-month capability-building programme — Lingesh and the BigGuru team will design it around your objectives, your industry, and your people.
