2022–2026
Set the multi-year identity north star that shipped multiple accounts, WhatsApp Contacts, and Usernames, reducing WhatsApp's dependence on phone numbers while preserving end-to-end encryption.
Problem
WhatsApp’s identity model was anchored to phone numbers, a 2009 decision that simplified onboarding but created compounding problems over time: phone numbers were exposed more widely than people wanted, users couldn’t separate personal and professional presence, and alternatives were offering more flexible identity. Phone numbers were central to signup, contact discovery, business messaging, group membership, and data sharing, so any change meant rethinking foundational architecture, while protecting privacy positioning and business-messaging needs, with only a small core team. The vision itself had to be compelling enough to move larger orgs without direct authority.
Approach
I held multiple time horizons at once: shipping near-term features to maintain credibility while building alignment around a multi-year vision. Delivering privacy infrastructure early showed the team could ship, while the strategy work scaled from feature-level to a company north star.
Process
Foundation
Exploratory work across an accounts vision, cross-family product definition, and an identity & expression brief. Ran a privacy design sprint that shaped pillar roadmaps and established me as connective tissue between competing organizational interests.
Vision definition
Defined the WhatsApp product vision and a dedicated identity vision, and presented the north star directly to the CEO as a dedicated deep dive, one of few design-led strategy presentations at that altitude. It identified evolution across Identity (usernames, flexible expression), Connections (a portable encrypted contact book), and Sign-up (reducing phone-number dependence).
Execution
Shipped incrementally while holding the long arc: phone-number hiding for ads and community groups; running two accounts on one phone (2023), letting people keep personal and professional presence separate without a second device or carrying two phones; Native Contacts (2024, encrypted storage via IPLS); and Usernames (announced 2025, rolling out 2026, and the single largest deliverable from the north star).
Outcome
The north star shaped WhatsApp’s public positioning around remaining the best choice for private communication. Multiple product teams aligned roadmaps to the vision. Phone-number hiding opened new opportunities for business messaging. Usernames roll out publicly in 2026, fundamentally changing how people connect without sharing a phone number.
Lessons
Multi-horizon work depends on credibility. Early ships created room for the slower strategy work, and the small team forced clarity in the vision.
