Wessel’s authority is operating record, not scholarship. She graduated from the University of Pennsylvania with a degree in political science, math, and Japanese, then joined Google’s APMM marketing-rotation program, spending a year building brand and product awareness in India before leaving at 23 [1]. In 2014 she co-founded WayUp (originally Campus Job) with college friend JJ Fliegelman [2] and ran it as CEO for seven years: an early-career hiring platform that reached more than seven million candidates and thousands of employers, on more than $40 million raised [1], until it merged with the recruitment-software company Yello in July 2021 [2]. That is a full company-building cycle: founding, scaling, and an exit, in the specific domain, hiring, that Management Craft cites her for.
After WayUp, she was a Visiting Group Partner at Y Combinator, working with more than 110 early-stage startups on enterprise sales, B2B marketing, storytelling, and fundraising [1]. She has angel-invested since 2016, backing more than 45 startups including Ramp, Scale AI, and Ro [1], joined First Round Capital as a partner in 2023 [3], and was named to the 2025 Forbes Midas Brink List (a watchlist for VCs expected to reach the main Midas List within a few years) [4]. None of this is peer-reviewed or credentialed research. She holds no faculty title, no published study; her word is high-density practitioner pattern-recognition across many hiring and investing decisions, not tested theory.
That’s the register Management Craft draws on her for, but the attribution needs a caveat the Calibration Call tool page currently glosses over. The tool page credits her with having “coined the term,” citing her 2025 X post. The post itself is a quick, typo-shorthand tip for founders, and it puts the word in scare quotes: “Do 20min ‘calibration’ calls” [5]. That reads as someone reaching for an existing word, not announcing a coinage: “interview calibration,” meaning getting a hiring team aligned on what good looks like before interviewing starts, is an established recruiting term that predates her post by years.
What she did add is specific and real: a named, concrete technique. Call two people who’ve excelled in a role you’ve never hired for, before you interview anyone, to learn what great and failed performance look like [5]. MC should credit her for popularizing that specific technique under this name, not for coining “calibration” in hiring. Her word carries real weight on early-stage hiring calibration and go-to-market hiring, earned from having made those hires herself and coached founders through hundreds more [1]. It carries none on management theory broadly, large-organization practice, or anything outside the founder/early-startup register she has actually lived in.
