Backed by RevenueCat as an official New York App Week event. Thank you!

A full room at Growth Gems & Screw-Ups

How the night worked

Two boards, one vote, ten minutes on the mic.

The Growth Gems board

Everyone sent their best subscription app insight with their registration. Each one was printed and put on the wall with its author's name.

The Screw-Ups board

The most expensive mistakes people have made, written anonymously on the night and pinned to a second board.

Votes and the mic

Attendees voted for their favorites on both boards, and the top gems and screw-ups were shared on the mic before the end of the evening.

Market the moment, not the feature. People do not want another AI productivity app. They want to say a thought once and trust that the right action will be ready when it matters.
That is how I'm building and positioning Dayly: one clear outcome people instantly understand, remember, and share.

Plan the tweet/TikTok video before you build the feature. If you can't see it going viral, it might not be something your users will care about either.

Your experiment doesn't end with the Ship / Kill decision. It ends with a learning, which feeds your next experiment, your team's shared knowledge, and your database of learnings. Experimentation programs work best when they are shaped as loops, not linear processes.

AI makes it incredibly easy to build and ship things now. But shipping more stuff doesn't mean you're learning what people actually value. The opportunity isn't just to use AI to build faster, it's to use that speed to figure out what users really care about faster.

Write your funnel as a chain of ratios. Each ratio is a different lever: creative, onboarding, paywall, targeting. Mine told me to stop buying trials that never paid and target the age group that did. Revenue doubled without changing the app.

Retention

Support is not just where problems get solved. It is where loyalty gets built. A support ticket can become a product insight. A refund request can become a saved customer. A complaint can become a fan. Treat people better than they expect when things go wrong.

Build your app for the people who actually pay you, not the people you wish were using it. Your target market might surprise you. When you find the users who truly love your product, nurture them and lean in. Early on, you cannot reach everyone. Reach the people who care most.

RetentionProduct

Real-time drop alerts don't retain — timing does. Subscribers who set up 3+ specific alerts (not just "notify me of everything") retain 2x longer, because the app becomes tied to a specific outcome they're waiting on rather than generic noise they eventually mute.

Put Monthly, Annual and Lifetime on the same paywall and annual stops being your biggest ask. It becomes the middle option, not the lowest commitment or the highest. That's usually where people go. Behavioural researchers call it the compromise effect, or extremeness aversion, and it's the reason "good, better, best" is everywhere from wine lists to SaaS pricing pages.

Don't end onboarding on your home screen: send users straight into the core feature. We redirected the last onboarding step to a feature instead of the app's home page, and it increased by 20%.

The value of TikTok acquired users is very app dependent (e.g., low value on an education app but high value on a dating app).

Amanda MadarasRevenueCat · AE

Onboarding and Activation

Your activation funnel's biggest leak is usually a step you can simply remove, not a copy tweak. Audit each onboarding screen for drop-off and cut any screen that isn't doing real qualifying or delivering value — fewer screens beat better copy.

We stopped showing the paywall during onboarding and placed it right after the user generated their first study card. Trial conversion rose from 4% to 10%.

Aurelien SansonAce Global

The rule we now apply everywhere: the last screen before the paywall must be the screen where the product visibly does its job. Not a feature list, not social proof. The thing working, on their input.
On one of our apps (it turns lecture notes and podcasts into revision sheets), we added a generation animation just before the paywall. Trial conversion rose from 4% to 10%.

Charles Galtier d'AuriacAce Global

Paid UAMonetization

For web2app paid acquisition, you CANNOT offer free trials, because tons of free trial starts are debit cards with low balance that will fail to convert — and all of those free trial starts will train your paid ad algorithm to find those low LTV users.

Web2app works! But copying the typical web2app funnel isn't always the best option despite what other's say. Also, be careful with cannibalization of app2app campaigns. We found it best to separate the event data sources completely.

Daniel LauPrecious · CTO

Onboarding and Activation

Onboarding drop-off is often caused by one of three problems:
1. Trust ("I'm not giving you that yet."),
2. Context ("I don't get what this is.")
3. Value ("I get it, but I don't feel it").

Daphne TidemanGrowth Waves

MonetizationData

Your "net-to-gross" on web is lower than you think. Everyone models Stripe at ~86% net. When we reconciled every line (processing, FX conversion, disputes, Radar, Billing, Invoicing) across a full year, it was under 84%. That two-point gap is invisible in payout reports and silently eats your ROAS target. Do the full reconciliation once a year and re-base your CAC ceiling on the real number.

Dogukan NefisWowoo Dijital · Co-founder

Onboarding and ActivationMonetization

When scaling UA, we saw a massive drop-off on the hard paywall right after onboarding. Instead of just tweaking copy/price, we tested a dynamic personalization recap right before the paywall screen (showing calculated custom insights based on their inputs). It increased our onboarding-to-trial conversion by ~24% because it built immediate perceived value and made the paywall feel like the natural next step rather than an abrupt roadblock.

Ad MonetizationData

Ad revenue is a great data source: for example looking at how quickly eCPM decays between impressions tells you how valuable a user is for subscriptions.

Felix Braberg2.5 gamers

Monetization

Optimizing for conversion alone can be misleading: the highest-converting paywall doesn't always create the best customers. Test paywalls as part of the full user journey, measuring not just conversion, but activation, retention, and LTV. The interesting part: a tiny paywall change can reveal that you were selling the wrong value proposition all along.

Giulia BorghiMode Mobile

Onboarding and Activation

When a funnel has multiple links, banners and calls to action, users are more likely to leave the intended journey. Before increasing spend or rebuilding the experience, remove unnecessary exit points and measure whether completion improves.

Adding new markets gives an advertising platform a larger pool of potential customers to learn from. If those markets share similar intent and economics, expanding geographically can reduce acquisition costs rather than simply increasing volume.

Use fast, inexpensive formats to establish whether a message resonates before investing in higher-production creative. Once an angle produces a meaningful signal, develop it through UGC, influencers and more ambitious executions.

Hannah ParvazAperture · Founder

Onboarding and Activation

The first screen of your app for new users is often a missed opportunity. This is a large drop off point, and almost every app just shows "Sign up" and "log in" buttons. Create an instantly engaging experience to pull people in and get them progressing through your flow. Opal has an interactive rock to break, Flo has a video animation, Headway has a curiosity hook.

Jacob RushfinnBotsi

Use the onboarding as a guide to make the user understand the aha moment of the app (aha moment being the reason that the user feels like your app is useful to them).

Onboarding and Activation

Long onboarding is not always a bad thing (30+ screens) when there is a value in it (we have a 85% conversion from session start to last onboarding screen)

Jenia ZimmermanAtta · Founder & CEO

Onboarding and Activation

A partial onboarding is better than a paused onboarding. In our fintech product, where users had to link financials and business documents, letting them skip even required steps and come back later with a checklist of what was missing improved time to value. Users may have to complete everything to reach value, but preventing stalls on missing information keeps momentum during activation.

Teresa MayedeSolid Starts

Onboarding and Activation

The first and most important job of your onboarding is to convince the user not only that your app category will solve their problem, but that your app specifically (not a competitor's) will solve their problem. Frame the conversation by using language like "What makes my app unique?" as opposed to "Here's what my app does" (especially if a bunch of competing apps basically do the same thing).
I launched an onboarding flow that started with "what makes my app unique?" and boosted LTV 160%.

TikTok farming saved Flamme. We didn't post from one brand account. We warmed up new fresh accounts, posted native content on each, and kept doubling down on whichever formats got traction. Do this over and over again and you hit 50m+ views :)

UGC creator loyalty is critical to scale up a UGC program. Run your entire UGC program in one group chat. Share viral videos within the team, share 5 star reviews from the app store, give praise to your creators, do an analysis on why you think their video did well. Make it as easy as possible to help them go viral and hit view bonuses. This will improve buy in among all creators in your UGC program if they feel like they are a part of a team. Invest in them, they will invest in you.

There is a unique middle ground between organic UGC and paid ads where you can create organic UGC that doesn't go viral but gets the comment "what app is that" — run only those organic UGC videos as paid ads, and create a much cheaper paid creative engine than traditionally very expensive paid ads, bonuses and usage rights. Most people are only focused on organic UGC engine or paid engine but we have discovered a ton of value right in between.

Our biggest screw-up early on was treating TikTok and Meta Ads with the same creative format. On TikTok, high-production 3D UI showcases completely flatlined with sub-1% CTR. We pivoted to raw, native UGC hooks with split-screen before/after reactions and problem-agitation hooks in the first 2 seconds. That cut our blended CPI in half and allowed us to scale ad spend profitably without tanking trial-to-paid retention.

When you find a creative that works, squeeze it much harder than you think. I often see teams constantly chasing the next big concept, while moving away from winners too quickly. Instead, take a winning creative and break down why it worked: the hook, angle, format, talent, visual, message, or offer. Then build iterations around those individual elements. Sometimes your next winner is just one iteration away from the one you already have.

Winning ads are art and patterns. With enough performance data you can build video creative down to the edit cuts: timing, color, sound design. Humans are predictable. Treat creative like an engineering problem and you stop gambling on taste.

Signal engineering > campaign optimization. We built ML into our onboarding to estimate each user's conversion value / expected LTV very early in the journey. Instead of sending Google every conversion, we selectively send the signals we believe represent genuinely valuable users. CPA increased ~10%, but estimated LTV roughly doubled, with significantly better retention. Don't just optimize the ads — engineer the signals the algorithm learns from.

Jus AvilaCarrots

Influencer Marketing

Treat influencers as a performance channel, not just a media channel. We hire creators at scale and use paid CPM as the base, but layer incentives around valuable in-app actions rather than just views or installs. We also gamify performance between creators. The best influencer programs align creator incentives with actual product outcomes.

Trending formats look the same no matter who runs them, especially the long Pixar-style cartoon ads. Swap the app name, and it could be any app.
Use trends wisely:
• Brand recall is low, and viewers remember the format, not you.
• Your direct competitors can copy them in hours.
• Borrow the trend's hook, but build the rest around something only your product can do, and show it in the ad.

Monetization

Instead of selling a “3-month subscription,” sell a “12-week plan” built around the result the user wants to achieve. It’s essentially the same product, but the way you present it changes what users feel they’re paying for. People aren’t necessarily looking to buy another subscription, but they might feel differently about an outcome.

Not all signups should be treated the same. Build a simple onboarding-flow where you adapt pricing, offering, and communication per segment. At Tracklib 70% of users were beginner-producers, and they had a 68% lower conversion rate. A better flow for this segment along with phased pricing led to a 80% reduction in Meta CAC. Additionally, by breaking out segments we were able to acquire experienced / pro producers at better scale which led to a 300% increase in residual revenue.
