How things would have work around if Microsoft released MSN Messenger for Android and iOS. They had the userbase and the brand already.

Why didn't MSN become what WhatsApp is today? I always wondered how they could screw this up. Smartphones are perfect for chat apps, that's basically what they are supposed to be used for, and MSN / ICQ already covered a gigantic portion of the instant messaging market. Did they just assume people would stay on desktop for chatting forever?

Yeah Microsoft was too dysfunctional before, but they’ve improved a lot recently and are killing it in many areas

My experience is, # of engineers is directly related to # of product people, which is in turn related to quantity (not quality) of ideas that the founders/leaders are desperate to try out. Higher quantity of ideas == More engineers. Higher quality of ideas == Fewer engineers. WhatsApp success is not about what WhatsApp did, it's about everything they didn't do. No desktop, no browser (until after reaaaaaaallly long),…

That's all nice and well, but some of your examples are not things that save effort -- using phone numbers is surely better for network effects, but not in any way simpler then having regular account registration, unless you just completely ignore security. WA apps are not better than the competition. Basic stuff like a way to disable automatic downloading of media for groups you are in is still missing. No desktop a…

I think they displaced Skype, mumble and teamspeak too.

WhatsApp was originally a super simple product. Send and receive messages. It was fundamentally a solved problem. It was all about the fact you could send free messages in a world where sms cost 10 cents a message. It wasn't that their messages were faster, their messages were anything other than free. They had a year fee of $1. Which I never paid yet I used their service anyways. The reason they were able to scale s…

> The reason they were able to scale so large with so few devs is simple, their product was super simple. 50 tech people to build a messaging system is actually a lot. Tell that to Twitter. Whatsapp staying at 50 instead of growing to 5000 is impressive.

Different product. One is a social media network and one is a messaging app.

It crossed my mind while considering this that a figure like this doesn’t mean the same as it would have pre-cloud infrastructure. My team is fairly experienced but not so much in infrastructure. Even so, we build and deploy on Google cloud with fairly excellent scalability and ease. Ten years or longer ago I suspect the story would be different - the infrastructure and scale constraints could have pinned us at times…

Whatsapp used bare metal servers. It isn't hard to do, just that people no longer learn to do it.

> Ten years or longer ago I suspect the story would be different

Whatsapp was built 12 years ago.

Not true. They were charging $1/year from users in the richer markets. They could easily reach hundreds of millions per year in revenue if they followed this model.

~$30M revenue in 2014 from 600M users. The vast majority of people will leave your service if it goes from $0 to even $1. So no, I don't think they could "easily" scale that up.

It didn't go from $0 to $1. It was always "$0 to most, $1 for those that really didn't care about paying because they knew that anything else would have much higher real costs"

Hell, If WhatsApp ever got to say "Facebook wants to buy us, but we are also considering changing to a pay-what-you-want model to avoid selling out", I'd easily give them $10/year without batting an eye.

I looked at it this way. The thing most engineers, hero's or not, want to work on is new projects and to build products customers enjoy. The last thing they want to work on is maintenance. In my last personally owned company, small as we were, the engineering team and I documented how things worked as part of what we did every day. We found that by having the inner workings documented so that anyone in the team could…

I must be weird. I love maintenance. The best bugs come out of that. And it's hard to tell if a system was well designed except in hindsight; maintenance programming is the best place to be for that.

You’re not alone. I may not love “maintenance”; but, I do love resolving performance issues and shoring and standardizing existing stuff a lot. I think I most like a balance.

There was a joke, or maybe anecdote, going around the Israeli high tech industry when Google purchased Waze When it came time to get an overview of the codebase being purchased. The Google Maps car navigation iOS team had over 200 engineers. The Waze iOS team had 2

off topic but I recently started working with an Israeli tech company and I'm amazed by the culture they have, what about Israel produces such high levels of entrepreneurship?

I really don't like working for those 100 darts people. They are a royal pain in the ass.

Much better are the folks with a solid vision who can drive folks to execute on it, successfully.
