I recently reflected on a candid conversation with Tara Viswanathan, co-founder and CEO of Rupa Health. Tara started Rupa Health in early 2018, but the product vision today looks very different from what she first built. As I listened to her zero-to-one story, I mapped each pivot to familiar product/market fit lessons I see across founder-led GTM and product discovery.
For the first half of her journey, I paid particular attention to the elusive startup holy grail of product/market fit. The aha moment that the first iteration of the product wasn’t going to work arrived quickly and unmistakably. Tara is incredibly candid about all of the things she had to learn the hard way as a first-time founder going from zero to one — a thread that resonates deeply with my experience in product management leadership.
One takeaway that stood out: why she thinks hiring a few folks before finding product/market fit was one of her earliest mistakes. In the hunt for PMF, premature hiring can dampen learning velocity and blur signal. My playbook is to stay lean, keep customer feedback loops tight, and lead with founder-led GTM until retention and engagement data justify scale.
We then dive into her decision to create a new product knowing that it wasn’t going to be the thing that ultimately worked — but was bullish that it would lead down the right path. I think of these as “stepping-stone” bets: purposeful experiments that expand your surface area for learning, even if they’re not the final destination. Done well, they accelerate discovery, de-risk strategy, and set up the next high-conviction move.
In the second half, she talks about hiring Rupa’s early team, and her tactics that go against the grain of conventional startup wisdom. For starters, she leaned heavily on external contractors rather than full-time employees on the path to product/market fit — and she thinks more founders should consider doing the same. She also dives into why she hates job descriptions, and what she prescribes instead. In my practice, I often swap static descriptions for outcome-based scorecards and paid trial projects to align expectations with the realities of 0→1 execution.
As a founder still in the trenches, Tara is game to get super tactical about the things she’s tried along Rupa’s winding journey that did and didn’t work. It’s a must-listen for other founders — or anyone that’s got a burning curiosity about what it’s actually like to be an entrepreneur. For product leaders, the through-line is clear: protect speed, test boldly, hire carefully, and let evidence — not ego — pull you toward product/market fit.
