Kayvon Beykpour co-founded Periscope, the live-streaming platform acquired by Twitter in 2015 before public launch, then led consumer product at Twitter — rising to head of product and GM of consumer — until Elon Musk’s acquisition forced him out during paternity leave in 2022. This episode covers his decade at Twitter: how he broke through a stagnant product culture, what he told Elon in their first meeting, and the structural diagnosis he offers for why large platform companies stall.
Key ideas
- Beykpour diagnosed Twitter’s stagnation as a structural problem: a functional org model where the head of consumer product had no engineering or design reports meant he could not change culture with one hand tied behind his back. The problem was the structure, not the people.
- To unstick the org, he built a “sacred cows” list — every assumption the team treated as untouchable — and systematically attacked it. New products (Super Follows, Communities, newsletters, Topics, Fleets, Twitter Blue, Spaces, live video) came from acquihires and junior PMs hungry enough to challenge incumbents.
- During a two-hour session with Elon and Scott Belsky (Walter Isaacson silent in the room), Beykpour recommended which people to keep. Most remain at X and are now empowered. Projects he championed — Community Notes (then Birdwatch), Spaces, Communities, the Creator Programme — all survived the transition.
- Periscope, co-founded by Beykpour and acquired by Twitter in 2015, became the direct template for Instagram Live, TikTok Live, and Facebook Live. Twitter shut it down in 2021 after deprioritising standalone live video.
- Beykpour applied Jobs to Be Done thinking to understand what users actually hired Twitter for, which shaped how he prioritised the roadmap.
Transforming Twitter’s product culture
Beykpour arrived at a company where senior product leaders had strong opinions but no structural mechanism to resolve disagreement. Under a functional org — product, engineering, and design as separate silos — shipping anything new required consensus across all three, and without a CEO who actively tiebreaked, the default answer was no. Beykpour’s diagnosis: the org model itself killed momentum, not the people inside it.
His intervention was the sacred cows list. He catalogued every product decision the team treated as settled and started changing them. The first wins came not from convincing incumbents but from routing around them — acquihires brought small teams with no stake in existing conventions, and junior product leaders who had not yet learnt what was “impossible” shipped things senior PMs had blocked for years.
Output over his tenure: Super Follows, Communities, newsletters, Topics, Fleets, Twitter Blue, Spaces, and live video. Not all succeeded commercially, but the cadence of shipping changed.
When Parag Agarwal replaced Jack Dorsey as CEO in November 2021, he restructured Twitter from a functional org to a GM model and promoted Beykpour to GM of consumer — giving him direct ownership of engineering and design for the first time. The acquisition closed before that structure had time to compound.
The Elon acquisition
Beykpour was on paternity leave when Twitter was sold. He was fired.
Two days after the acquisition closed, Elon reached him on FaceTime. They met in person at Twitter HQ — Beykpour entered through a back door. The session lasted two hours. Scott Belsky was present; Walter Isaacson was in the room but did not speak.
Beykpour used the meeting to recommend the engineers and product leaders he considered foundational. Most are still at X and, by his account, now more empowered than under previous leadership.
The projects he advocated for — Community Notes (then called Birdwatch), Spaces, Communities, the Creator Programme — all continued under Elon. Beykpour frames this not as vindication but as evidence that good product bets survive regime change when they have demonstrated user value.
Periscope and live video
Beykpour co-founded Periscope as a mobile live-streaming platform before live video was a standard social feature. Twitter acquired it in 2015, before launch. The platform launched, grew, and then plateaued as Facebook, Instagram, and TikTok each built native live-streaming features — all modelled directly on Periscope’s product logic.
Twitter shut Periscope down in 2021. The reason was success, not failure: the features had been absorbed into Twitter proper, and maintaining a standalone app alongside the main product no longer made sense. Beykpour treats the shutdown as a correct decision.
The broader lesson: Periscope created a product category, then was deprecated when that category became infrastructure. The template outlived the template-maker.
