I'm Senthil Kumar — a B2B sales trainer and sales coach based in Chennai, and one of the more experienced sales trainers working with manufacturing and B2B services firms in South India. What I do today is built directly on what I sold, what I built, what I closed, and what I lost over the last two decades. Here's the longer version.
I spent the first major chapter of my working life — about ten years of direct, day-to-day field selling, inside a seventeen-year arc — selling capital equipment for European manufacturers across India. CNC machines. Packaging systems. Precision engineering tools. Office automation. Industries where the sales cycle runs in months, not weeks, where the buyer has heard every pitch, and where the only thing that closes a deal is the relationship you've earned before the proposal arrives.
One of the firms I sold for was Madaula SA, a precision engineering company out of Barcelona. The work took me across Tier 1 and Tier 2 manufacturing markets — Chennai, Coimbatore, Pune, Bangalore, the NCR belt, and dozens of smaller industrial towns most people couldn't find on a map. I sat in cabins on factory floors. I drank chai with procurement heads who'd seen ten salespeople that month. I waited two months for one signature.
That was the field that taught me what works when the buyer has budget but no urgency, when the competition is cheaper, when you're the new vendor nobody has heard of. Everything I teach today comes out of that period.
Between then and now, I founded and ran two businesses of my own. Both eventually closed.
That's a fact I wear with some care. Failed ventures are easy to brand as a setback, but the truth is more useful: each one taught me things I could not have learned any other way. The pressure of payroll. The difference between revenue and cash. The way a founder's confidence can quietly drift into self-deception, and how hard it is to spot from the inside.
When I now work with founders and sales leaders, it is from inside that experience — not above it. The conversation isn't theory. It is: I know what this feels like at month-end. Here is what I'd do if I were sitting in your seat.
Alongside selling, I have run an independent resume writing practice since 2008. Over the years it has grown into a body of work covering six thousand-plus professionals across India, Canada, Australia, the UK, the Middle East, and Europe — including partnerships with outplacement firms like LHH.
It's an unusual second discipline for a sales trainer to have, but it has shaped my work in two specific ways. First, it taught me how professionals across every conceivable industry and seniority actually think about their own careers — the language they use, where they get stuck, what they over-explain and under-claim. Second, it sharpened the listening, questioning, and reframing skills that sit at the centre of how I now train salespeople. The work of helping a CFO articulate her own value to a hiring committee is not very different from the work of helping a sales rep articulate her customer's value back to that customer.
Trust-First Selling is the name I've put on the way I teach. It isn't a slogan. It's a description of what I noticed actually closed deals, summarised after thousands of real conversations with plant managers, procurement heads, and business owners who had heard every sales trick in the book and trusted none of them.
The core idea is simple. In complex B2B sales — long cycles, technical buyers, multi-stakeholder decisions — the trust you build before the pitch is doing more work than the pitch itself. Most sales training teaches techniques. The techniques matter, but only after the trust is in place. Without that, no technique survives contact with a real buyer.
Around that core idea, the methodology gives reps and managers a working set of frameworks for discovery, value-reframing, objection handling, negotiation, and account development. It is, deliberately, the opposite of motivational sales theatre. It is closer to how a senior, experienced rep actually thinks — written down so a younger rep can use it.
I now work across four programmes — sales training, sales coaching, sales consulting, and AI sales coaching — with SMEs, mid-market firms, and L&D organisations. Active engagements run across manufacturing, building products, contracting, and B2B services.
The work is intentionally selective. I take on clients where the leadership is honest about the problem, where the team is ready to be coached rather than just trained, and where the outcome we're after is real behaviour change — not a feel-good event. I don't claim to be one of the best sales trainers in India by reputation; I'd rather earn that one client at a time, by what teams actually do differently after the engagement.
I'm based in Chennai. I work across South India regularly, and travel for the right engagement. If you want a fuller picture before getting in touch, my LinkedIn profile has the working history, recent activity, and a few public threads on sales and selling.
