Messaging

Google Allo

Google Allo was a 2016 "smart messaging" app built around the new Google Assistant, and it was dead on arrival. It launched into a market already owned by WhatsApp, iMessage, and Facebook Messenger, with over a billion users each, and offered nothing compelling enough to make anyone switch. It never reached 50 million users. Google paused it after 18 months, redirected its team to RCS, and shut Allo down in March 2019, one more entry in Google's long graveyard of abandoned messaging apps.

Narrative

The story

The ambition

Google launched Allo in September 2016 as its smart answer to messaging. The hook was the Google Assistant built right into your chats, along with smart replies that suggested what to say and playful stickers. After years of watching messaging become one of the most important things people do on phones, Google wanted an app that showcased its artificial intelligence and finally gave it a foothold in the category.

The rise

Allo shipped alongside a companion video-calling app, Duo, and the two were meant to be Google's fresh start in communication. Duo, simple and focused, quietly caught on. Allo, the flagship, was the one Google talked up as the future of smart messaging.

The cracks

Almost no one used it. Messaging is a network-effects business: people are where their friends already are, and in 2016 their friends were on WhatsApp, iMessage, and Facebook Messenger, each with well over a billion users. Allo gave them no compelling reason to move. The Assistant and the stickers were novelties, not a reason to abandon the app everyone you know already uses, and Google barely marketed it. As one account put it, Allo was flawed from the word go, with limited usage, and Google was, as ever, painfully late to the messaging game. It never reached 50 million users, a rounding error against its rivals.

The collapse

Google gave up in stages. In April 2018, less than two years after launch, it announced it was pausing investment in Allo and moving almost the entire team to a different bet: RCS, the carrier-backed successor to SMS, rebranded as "Chat" inside Android Messages. In December 2018 it confirmed Allo would close, and on March 12, 2019 the app shut down, with a few of its features, like Smart Reply and GIFs, transplanted into Messages. Duo survived; Allo did not.

The aftermath

Allo became one more headstone in a crowded graveyard. Google Talk, Google Voice, Google Wave, Hangouts, Allo, Duo, Messages: the company has launched, split, merged, and killed messaging products for years, with no coherent strategy and constant changes of direction. Its dominance of search and Android never converted into a messaging user base, because owning the platform does not make people move their conversations.

The lessons

In a network-effects market, being late with a slightly cleverer product is the same as being irrelevant. Allo's features were fine and its AI was real, but none of that answers the only question that matters in messaging: why would I leave the app where all my friends already are? Google kept building new messaging apps as if the problem were the product, when the problem was the network, and every fresh launch split its own effort and its users' trust, teaching people that any given Google chat app might be gone in two years. Owning Android should have been a decisive advantage, and it was not, because a platform can ship an app but cannot ship the reason to switch. The serial relaunches are the real failure: not that Allo flopped, but that Google never decided what its messaging strategy was and stuck to it.

Structured analysis

What Went Wrong

Root causes

A market already owned. Allo launched into messaging dominated by WhatsApp, iMessage, and Facebook Messenger, each with over a billion users, and offered no compelling reason to switch. [2] [3]

No coherent messaging strategy. Allo was one of a long, changing line of Google messaging apps (Talk, Wave, Hangouts, Allo, Duo, Messages) that split effort and taught users any of them might be abandoned. [6]

Contributing factors

No differentiator, no marketing. The Google Assistant and stickers were novelties rather than reasons to switch, and Google barely marketed Allo. [3]

Immediate trigger

Paused for RCS, then killed. In April 2018 Google paused Allo and moved its team to RCS/Chat in Android Messages, then shut Allo down on March 12, 2019. [4] [5]

Visible symptoms

Almost no users. Allo never reached 50 million users, negligible against rivals with over a billion each. [3]

Warning signs

Limited usage from the start. Allo was described as flawed from the word go with limited usage, an early sign it was not catching on. [2]
