How iOS 18 is about to nerf mobile inviting -- and a brief history of viral growth from email to FB apps to SMS

First, here's the punchline: Soon the world will update to iOS 18, and it will add significant friction for users to invite their friends, hurting the growth prospects of many consumer apps. Why?

- the new flow will have many more steps as contacts will be ordered alphabetically, require multiple taps to pick the contacts shared to the app, and then more steps to actually invite. Each step will kill the conversion funnel

- In prior iOS versions, it would just ask you to approve access to your contacts, and you could present a list of people that could be tapped one-by-one, popping up an iMessage screen. This simplicity is about to go away.

- this won't kill viral growth on mobile, but it will make things much harder. If your app is high retention, things will be fine as you might invite a few folks over a long period. Or if you depend on creator sharing flows, where bits of content are posted on social media -- those won't change. But apps that explicitly ask for friend-to-friend invites will be hurt

This is just the latest step in a long history -- we've moved from spammy, broadcast style mass inviting to more targeted inviting (benefiting high retention apps), and we'll see more over time.

A bit on this history:

- all of this is now ancient history, but the early dynamics of viral growth started in email as the platform of choice in the early 2000s. Early social networks had you input your friends emails, one by one, and although that was arduous and painful, it worked. The novelty effect of receiving an invite with your friend's name on it was so high that people would just sign up

- there were also early experimental viral loops that grew furiously without much of a product attached. For instance, a "birthday alarm clock" that consisted of an invite that "XYZ wants to remember your birthday, put in your info" followed by upselling if you want to add their birthday (and that of your friends). This team eventually went on to build Bebo. Or "crush sites" where you got an email saying, "someone has a crush on you" followed by you putting in emails to guess who they are, and those people getting emails too. Again, not much of a product experience, but these simple ideas gained millions of users.

- this was all supercharged by email importers. Clever growth hackers figured out if they could have you put in your email address and password to your Hotmail/Yahoo/Gmail, they could look through the addressbook and make it easy to import 100s of people, without requiring manual email entry. There's a fun history involving a 3rd party library to do this -- Octazen -- which was bought by Facebook early on, denying others this capability.

- email importing was a game changer since it meant that the average # of invites went from ~3-5 to 100s. Of course this caused an explosion of spam (or sometimes was referred to as "bacon" of friends who opted you into invites). Eventually, by the Law of Shitty Clickthroughs, the performance of this loop started to wane as people got more skeptical. "Whoops, I accidentally invited 200 of my friends!" followed by people disowning the app. A lot of these products like Tagged, Hi5, etc were pretty aggressive on this and they reached 100s of millions of users, but sometimes without the best retention.

- the other "dark pattern" that emerged (and is still used today) is to ask users to invite first before they can even use the app. The reason for this is simply mathematical -- the first day is when the cohort is the largest and hasn't had the chance to drop off. If you ask on day 7, probably >50% of your users are no longer active, and they have to invite at 2x the effectiveness to make up for the loss. Better to just put it in front, but of course it's an annoying UX

- eventually Facebook pulled ahead. There's a lot of reasons for this, but one aspect is that it was just the best product. And it because it was stickiest, it could also grow the most efficiently via word of mouth. If you have a lot of shots on goal, you can put an invite flow in front of users in a subtle way, rather than pounding on them to start. Instead of being focused on inviting, FB could just focus its users on connecting with existing users on the platform. This is a major factor in why I think high retention is still the key to high virality. LinkedIn went a different path, and hit email virality hard but also opened up big channels in SEO and via recruiters, so even though their frequency of use was not high, they still built out their audience (albeit more slowly than FB)

- email began to wane, and a subsequent S-curve started as the Facebook Platform launched, and you could build apps that would then invite users on that network. Huge audiences were built overnight by Zynga, Slide, and others. This is probably the high-water mark of viral loops where all the ideas around "k-factor," A/B testing, etc began to spread widely in the community. (I was blogging furiously right around then!). Funny enough, I always felt like people never actually knew how to calculate k-factor / viral factor / etc, even though there was a lot of discussion around it. But the awareness was there

- eventually both email and the FB platform both ran through their S-curves, particularly as mobile was emerging. For email, the primary platforms started to push users/devs towards OAuth, and controlling how much data was scraped -- that way spam was lessened. They also increased their filtering more aggressively, so that if you were emailing old/dead email addresses, for instance, that meant you were probably doing the mass email spam tactic and you should probably go onto a blacklist. Facebook turned down their growth channels as well, eventually pushing companies to buy traffic rather than using abusing their notification channels. And of course, mobile emerged.

- but before I hit mobile, let me also say that new forms of virality started to emerge as well. YouTube saw tremendous growth via link sharing and embedding, rather than inviting. The viral loop there works (and still works) in an organic way, where creators upload content, share it broadly, and some of those users then share it further. Some users retain and keep sharing over time. This was supercharged in the early days by allowing people to "embed" videos onto their blogs and MySpace pages, generating a nice bit of traffic over time. This avoids the spam issues of invite loops but it's just a slower loop, comparatively.

The emergence of mobile

- in the early days of mobile, plenty of founders tried to repeat the "slash and burn" spam tactics that had dominated the last ~5 years. You could auth your contacts, and they would use an SMS service like Twilio to send server-side invites to people.

- the experience was not great. Your friends would get an SMS like, "X has invited you" but it would be from a random number. However, SMS is different than email virality in a number of ways. First they are stricter laws because of the "TCPA" laws in the US, compared to CANSPAM for email which is just softer. And because SMS is real-time, people would receive the invite texts and immediately text back their friends. Also, imagine having 100s of text invites sent out to your friends with one click. A bunch of them would text you at once. You would be very embarrassed, causing an immediate bounce on the product.

- Lawsuits were filed. Startups stopped doing this. And then the question became, what's next?

- Devs are still trying invites. The current dominant tactic has been to show users an invite screen but when you tap on a contact name, and it pops up iMessage with a little message to send. You've all seen it.

- But to compare to back in the email days, things are different. We're now back to inviting just a few people at a time, not 100s. The quality of the invite matters more than quantity. Previously you might have <5% conversion rates on the 100s of email invites you sent out, and that was amazing. For SMS, you're looking for 20-50% CTRs and very high signup rates, but you tend to send <5 of them. The audience tends to be young, since they haven't seen these mechanics. The older you are the more you try to skip them

- The other idea is to wrap invites into the utility of the product. I mentioned link sharing before, but having great video/photos/etc in your app and getting people to share it with a watermark/link can work. Or while I was at Uber, I worked on a project to put an invite link into the "Share ETA" feature. Or with Dropbox, people acquire their coworkers by sharing folders with them. These are deeply natural viral loops that don't have to create spam or issues

The iOS 18 changes will be big, of course, but in the end probably a good thing in that they incentivize sharing/inviting that's based on utility rather than upfront sharing. Over the past decade, the ability to do mass invites has been dropping precariously and what it means is that the product has to be sticky rather than to engineer growth simply through mass inviting. And the best growth channel, in the end, is being such a killer product that people will tell their friends without being prompted for it. We've certainly seen that, with all the AI tools in the past year.
