I recently sat down with Kesava Kirupa Dinakaran, co-founder and CEO of Luminai, a B2B software tool that helps automate any manual process down to just one click. Coming from years of product leadership, I was immediately drawn to how a seemingly simple promise — one click — can reframe entire operating models and unlock product-market fit in B2B SaaS.
Dinakaran’s path into building software products is anything but conventional. A former Rubik’s Cube champion and back-to-back Hackathon winner, he brings a competitor’s precision and a builder’s curiosity to the craft. The founders stumbled on the idea for its automated “one-click” product by accident, at a corporate hackathon — the kind of serendipity I’ve seen repeatedly catalyze category-defining products when teams are close to customers and willing to ship fast.
Formerly called Digital Brain, Luminai is a Series A startup that’s raised nearly $20 million since its launch out of Y Combinator in 2020. That trajectory underscores a disciplined focus on value creation over vanity features — and the organizational courage to concentrate resources where customers feel the most impact.
In our conversation, we explore the psychology behind the sales process, why sales leaders should consider pitching straight to the CEO and Dinakaran’s decision to scrap hundreds of lines of written code to focus on building out their most beloved customer feature. That decision is a textbook zoom-in pivot — narrowing scope to amplify value — and it’s one of the hardest, yet most effective, moves a product leader can make in the search for product-market fit.
Zooming in is not just about cutting; it’s about conviction. When the data and customer narratives converge on a single, beloved capability, the right move is to double down. My playbook in these moments is simple: validate with qualitative signal (customer pull, urgency, and willingness to pay), quantify usage concentration (feature adoption depth, not breadth), and model the business impact (time-to-value, implementation friction, and sales cycle acceleration). If a feature materially compresses time-to-value and reduces change management, it deserves roadmap primacy.
We also dug into the psychology behind enterprise sales and why sales leaders should consider pitching straight to the CEO. In founder-led GTM, this tactic creates a high-bandwidth feedback loop: the economic buyer frames outcomes, we test narrative-market fit in real time, and we avoid the trap of selling “capabilities” instead of transformational results. In my experience, early alignment with the CEO sharpens qualification, shortens cycles, and forces clarity on the business case.
On the surface, Luminai may seem like just another B2B SaaS startup, but with nearly half the team comprising of former founders (seven of which are ex-YC founders), Luminai is a true example of how the co-founders can really make their mark on shaping their company on the path to product-market fit. That founder density matters — it accelerates product discovery, normalizes rapid iteration, and builds organizational muscle for decisive pivots like the zoom-in. The result is a culture that prizes customer outcomes over internal preferences.
My takeaway for product leaders: don’t wait for perfect certainty. If a single feature repeatedly earns love, compresses onboarding, and closes deals, earn the right to focus — even if it means scrapping code and saying no to adjacent asks. Pair that focus with founder-led GTM, pitch the true economic buyer, and measure success by outcomes, not output. That’s how teams move from zero to one in B2B and create durable, defensible product-market fit.
