7said about them ↓ Everything Crystal Widjaja said on any show that made the record, most notable first. Each card names its show and opens the statement there.
Widjaja: Scaled products should target 60% week-over-week retention for free tiers
“If users are coming back, if it's a free product, 60%, right? It has to be at least 60% if it's a free product week over week. If it's a paid product, I usually look at that more as like maybe 20 to 30%.”
Widjaja: CleverTap is preferable to Mixpanel and Amplitude for mobile tracking
“If you need an app mobile device event tracking, I usually recommend Clevertap because Mixpanel has unfortunately failed me a lot and Amplitude doesn't have the CRM components that I would need all in one space.”
Widjaja: Why super apps dominate Southeast Asia instead of the US
“I think the sentimentality of a conglomerate is very different in Southeast Asia. So we've grown up with, you know, a specific conglomerate owning, not just the mall that you go to, but also the apartment building that you live in and the school that you go to…”
Widjaja: Product ideas are useless without running experiments on real consumer behavior
“If you don't have a tested hypothesis, if you can't think of a way to run an experiment, then honestly, that idea is pretty useless. Like maybe it makes sense to the market, to the model. But you could have weird consumer sentiments, like not everyone is a rat…”
Widjaja: Startups can detect reliable behavioral trends with 30 data points
“The data you get back generally does not change, but it's precision will. So mathematically speaking, you're going to get the same level of trends, but the precision at which you understand those trends will become more deep if you have more data. But the unde…”
Widjaja: Startups testing with friends and family need nearly 80% retention
“So if you are much smaller, like your friends and family, that better be near close to 80%, no matter what, because if you can't even convince the people who care about you to use the product, it probably isn't gonna solve the job for anyone else.”
Widjaja: Visible branded drivers on streets primarily drove Gojek's geographic expansion
“There is a physical
Conception of a driver in a jacket driving around the city who was marketing Gojek for us.
And word of mouth actually was primarily driven by, I saw a driver on the street, so I knew Gojek was here.
And that actually was a huge driver of al…”
Widjaja: Artificial friction helps identify high-intent community users
“So we almost create this artificial friction to help differentiate how deeply a user wants something or needs something.”
Widjaja: Live case studies do not work well for growth interviews
“I don't think live works really well for these case studies. Like I want to see people put in the time and the work to do something to the best of their ability.”
Widjaja: High landing page bounce rates are usually copywriting problems, not product flaws
“If you have a lot of people landing on a webpage or an app and then not doing anything, then it's probably copy. Like they haven't even experienced the product. It's clearly not the product that's wrong. So how can you change the copy and resonate with the pai…”
Widjaja: Gojek saw 60% to 70% cohort retention in its early days
“I think I usually give teams like two to three weeks or frequency periods to see things flatten, but it better flatten around 60% for a free product. That's kind of, that's actually what we saw at Gojek early days. It was like, 60, 70% retention rates because …”
Widjaja: Driver top-up prompts drove roughly 60% of GoPay user acquisition
“It was huge. It was like, 60% of acquisition once we released that.”
Widjaja: Tracking metrics without altering action is entertainment, not real news
“Do not treat metric gathering as entertainment. Like it's not there for you to be like, oh, that's interesting. How novel and then not act on it. So real news is information that changes what you do in the real world. And if you don't change what you're doing,…”
Widjaja: Poor data tracking logs many events with minimal contextual properties
“The symptom of a bad data tracking approach is you have a ton of rows with a ton of events, but every event has like one property or no property being tracked.”
Widjaja: Onboarding complex tools creates a high opportunity cost for growth teams
“A growth team can go terribly wrong when they just try to like onboard a bunch of brand new tools that don't integrate well. And it takes six months to integrate fully. And then they get nothing done for six months. Like everything in growth is an opportunity …”
Widjaja: Gojek had around 170 million users across Southeast Asia
“So across Southeast Asia, we had about one hundred seventy million users.”
Widjaja: Gojek rented a stadium to onboard 60,000 drivers in weeks
“And we ended up renting a stadium to just hire like 60,000 drivers in a couple of weeks.”
Widjaja: Friend purchase social proof doubled new restaurant orders on Gojek
“And we did find that when we told people this friend purchased from this merchant, you would be twice as likely to purchase from a brand new restaurant than users who did not have this feature.”
Widjaja: Optimizing search on Kumu increased conversion from 60% to 90%
“For Kumu, it was things like users wanted to sign up and find their friends on Kumu. And so they were using search. Frequently search was underutilized API. It was kind of slow. We sped that up. Conversion rates go from 60% to 90%, like over the course of a fe…”
Widjaja: Unfamiliar products must anchor to familiar mental models
“So I think if your product does something that's not super familiar, you have to tie it to something that is.”
Widjaja: Gojek's first growth SMS experiment increased driver acceptance by 2%
“Our first real growth experiment, we were actually still the data team at this time, was to connect a quick Python script to the Twilio API that we had access to. And we SMSed a bunch of drivers through a CSV that we uploaded that said like, Hey, you're accept…”
Widjaja: Under 18% of computer science college graduates are women
“I think it's gotten worse over the past few decades, like below, 18% of college graduates are women in computer science.”
Widjaja: Pre-college CS classes equalize female college graduation rates
“We've seen studies at Carnegie Mellon that actually would create introductory computer science classes before the college class starts. And for the women who did join those classes, they actually graduated at Similar rates as their bail counterparts.”
