Twitter CTO Adam Messinger and VP of Product Josh McFarland to leave company; McFarland to join Greylock Partners as a general partner
Twitter CTO Adam Messinger, who has been the company's CTO for almost four years and with the company for five years, said today he was leaving the company.
Context & Ripple Effects
The departure of Adam Messinger and Josh McFarland is not an isolated exit but the capstone of a year-long drain at Twitter: Jana Messerschmidt and Nathan Hubbard announced plans to leave in May, Trevor O'Brien ran the apps product out the door in 2015, and by late December six of ten executives on the company's "leadership team" had departed in a single year, per Recode's tally of the CTO, COO, VP of Product, and VP of Engineering exits.
Losing both the technology chief and the product chief at once strips Twitter of its two most senior hands over what gets built and shipped. The one silver lining for the ecosystem: McFarland converts the operating experience into a seat at Greylock Partners, continuing the pattern of departing operators recycling into venture capital.
First-order effects
- Twitter must backfill two of its four most senior product-and-engineering roles simultaneously, with Messinger having held the CTO post for nearly four years — a gap that took until March 2018 to fill, when the company named Parag Agrawal as his replacement.
- Greylock Partners gains a general partner whose most recent vantage point was running product at a large consumer platform under public pressure.
Second-order effects
- Each senior exit raises the odds more follow: the related coverage shows the attrition compounding through business development, media, security (Michael Coates left in 2018 after three years), and ultimately product leadership itself, when Kayvon Beykpour was asked to leave in 2022.
- For a company already losing its bench, recruiting replacements becomes harder — candidates price in the churn rate, forcing Twitter to promote from within rather than hire from outside.
Third-order effects
- If the pattern holds, sustained executive churn at a high-profile consumer platform shifts decision-making to a smaller, internally promoted core — Agrawal rising from within to CTO is the template — while the departing operators migrate into venture firms like Greylock, tightening the operator-to-investor pipeline.
- A revolving leadership team also invites external pressure on strategy: when product direction changes hands this often, each new leader arrives with a mandate to take the team in a different direction, as Beykpour's exit later illustrated.
The trend: Struggling consumer platforms are seeing their senior operating benches churn toward venture capital, with internal promotions filling the vacuum and each leadership change resetting product direction.
