Sajith Wickramasekara is the co-founder and CEO of Benchling in Founder Mode: Sajith Wickramasekara, Founder & CEO, Benchling. The episode says he started the company as a junior at MIT, where he studied computer science and worked in biology labs, noticing that scientists still relied on paper notebooks while software teams had stronger collaboration tools.

His source role is to ground Founder Mode in ownership rather than slogan. Sajith says founder mode means caring about company standards at many levels, from customer relationships to press-release language and product details, because tolerated weak work becomes the standard others learn from. At Benchling’s scale, his main regret is letting himself and senior leaders become too distant from customers during fast headcount growth.

The episode also makes him a Stage-Appropriate Hiring and executive-fit case. Sajith says founders often know within 30 to 60 days whether a senior leader is working, but can postpone action by hoping coaching will overcome the habits that made the person successful elsewhere. His current operating stance is to trust his judgment sooner, challenge inherited playbooks, and make customer conversations non-negotiable for senior executives.
