Kayvon Beykpour

Longest-tenured head of product at Twitter, credited with transforming the product org from stagnant to shipping regularly (Spaces, Super Follows, Communities, Twitter Blue) Their core argument: Functional orgs only work if the CEO actively tiebreaks -- Twitter's functional model created years of deadlock under a disengaged CEO. The evidence is specific: Twitter failed to ship meaningful product improvements for years despite having talented individual teams -- the same people built extraordinary products after leaving. Furthermore, first year as head of product was 'walking through mud' because culture change required consensus across peer functional leaders. Parag Agrawal's immediate move to GM structure upon becoming CEO validated the structural diagnosis. In Kayvon Beykpour's own words: "If you're going to have a functional organization, you need to have a GM or a CEO who's extremely leaned-in to tiebreak and resolve conflict and make sure the team is moving quickly. And Jack, for all of his amazing qualities, just wasn't operating that way." (Why functional org failed at Twitter.)

Kayvon Beykpour was the longest-tenured Head of Product at Twitter, where he arrived through the acquisition of Periscope (the live-streaming platform that inspired Instagram Live and TikTok Live) and transformed Twitter's product org from a risk-averse, stagnant culture into one that shipped Spaces, Community Notes, and Communities in rapid succession. Their core argument: Betting on 'unqualified' people is one of the best ways to drive organizational change -- but only if you protect them and support their growth. The evidence is specific: Keith Coleman: acquihired founder who built Community Notes (Birdwatch), which most people at Twitter thought was a terrible idea. Furthermore, esther Crawford: acquihired founder who led Super Follows, tipping, and creator monetization. Beykpour himself: Periscope founder who became Twitter's longest-tenured Head of Product. In Kayvon Beykpour's own words: "Taking a bet on people and especially throwing them in a deep end, which on paper they may be unqualified for, I think is one of the best ways of driving change. And by the way, supporting growth, you've learned so much more when you're thrown into the deep end than in other contexts." (Explaining why betting on potential drives transformation, drawing on his own experience at Twitter.)

Co-founder of Periscope (acquired by Twitter); Head of Product and then GM of Consumer at Twitter, overseeing the launch of Spaces, Community Notes, and other major features Their core argument: The answer is not any single framework -- sometimes it is just good old-fashioned judgment and product taste, and you need leaders who can see when their frameworks are failing. The evidence is specific: Twitter's reverse-chronological toggle: team auto-reverted users to ranked feed after 24 hours because it was 'better for metrics'. Furthermore, community Notes was structured like a startup inside Twitter -- exempt from OKRs. Twitter Spaces required pushing tweets and ads down the page, hurting DAU and revenue short-term. In Kayvon Beykpour's own words: "Sometimes those things are aligned and sometimes they're not, and the answer isn't any one framework. Sometimes it's just good old-fashioned judgment and product taste." (On why no framework replaces product judgment.)
