リリース1ヶ月目 #個人開発
✅ 25000DL 突破
✅ 売上50万円 突破
🈚 広告費 0
1ヶ月間試行錯誤してみて割と成果出せたかなと思うので、大事だなと思ったことTOP3まとめてみました。
① SNSマーケ前提でプロダクトを作る。
投稿ネタが作りやすいものであるほどいいです。
注意点として、ユーザー目線にたって
｢なぜ他の類似アプリではなく、このアプリを使う必要があるのか｣
は最低限考えるようにしてください。
② SNSマーケは、量産可能な型を既存投稿を参考に作る。
Claude Codeでの量産に繋がります。
僕は毎日30本近く自動投稿し、投稿作成にかかった時間は週2時間程度でした。
③ 毎日分析をかけて、売上に繋がる要因(オンボ完走率・ペイウォール到達率・課金転換率・リテンション率など)を分析し即改善。
Xの海外ポストから情報収集し、質も高めていきました。
これによってインストール数当たりの売上が4倍以上に伸びました。
逆にあんまり気にしなくてもよかったことはASOでした。
ほとんどの方(インストール数の内98%)が、
SNS投稿閲覧→ストアでアプリ名検索
によりDLしてくれてました。
投稿の質によってストアコンバージョン率は変動し、基本58～62%台、質の高い投稿ができたときは70%に到達しました。
そろそろ次のアプリも完成するので、この方法が本当に再現性のあるものか確かめてみます。
まだまだ伝えきれてないこともあるので、またX記事にでもして投稿します。
時代に感謝して、個人開発/個人マーケ攻略しよう🔥
この方、2週間で2万インストール達成したって動画とその方法をInstagramに上げてて、僕もその方法を真似した結果3週間で2万インストール達成できた。

世界のエネルギーの常識を変えようとする16歳のCEO、@Kai_Sugihara。
前澤さんらから約4.7億円を調達して話題になったと思えば、今度はXでの幼い発言を大人たちに寄ってたかって叩かれている。
あのさ、16歳の頃の自分を思い出してみなよ。
あたしなんて、その歳で世界を変えるどころか、月極駐車場の事を「げっきょく」って呼んでた年頃よ？
発言が未熟？ そりゃそうでしょ。まだ16歳なんだから。
スティーブ・ジョブズだって、若い頃は傲慢で気難しく、周囲と衝突を繰り返した人物。それでも経験を積み、世界を変える偉業を成し遂げた。
もちろん、若いからといって批判されなくていいわけじゃない。事業の実現性も、発言の中身も、厳しく問われて当然。
でもね、批判と集団リンチは別物。
16歳の言葉尻を捕まえて、大人が勝ち誇ってどうするのよ。
彼が将来ジョブズになるかどうかなんて、誰にも分からない。
ただ一つ言えるのは、16歳で宇宙を目指している若者を、SNSのレスバだけで「無能」と決めつけるには早すぎるってこと。
若者の未熟さを笑う前に、その歳の自分が何に挑戦していたか思い出してみな?
Zero IndustriesのCEOの海のことはよく知ってるけど、ただ意識高い学生が挑戦してみたなんてレベルじゃないよ。
まじで頭の回転早いし決断力も行動力もある。
会って話せば分かる。
知識量と情熱に圧倒されるはず。
｢16歳にしては｣なんてレベルではなく人として。
確かに性格荒いとこあるけど、困ってる人がいたら迷わず声掛けて助けるような、人情あっていいやつだよ。
まあ暴言多いからX見てるだけじゃ悪くしか映らなくても仕方ないとは思うけど笑
個人的には将来最高の起業家の1人になってると思うし、ここからさらに色々経験してBIGになっていくだろうから楽しみ！
また近く行く時は進捗聞かせてな！
人類のテクノロジーの変革期楽しもう❤️🔥

马斯克在最新的访谈里聊到 AI 抢走所有工作时，用了一个极其温柔、但也极其残酷的比喻。
他说：未来人类的工作，大概率会变成园艺。
你根本不需要自己在后院种番茄和土豆，超市里买到的永远比你自己种的更快、更便宜、品相更稳定。
但今天依然有很多人在阳台种花、在院子里拔草，甚至花一整个下午为朋友做一顿自己种出来的晚餐。
这件事在纯粹的工业效率上毫无意义，但它带着一种人类之间独有的温度。
很多人聊到 AI 替代人类，第一反应永远是恐慌、失业、降薪、社会阶层崩塌。
但马斯克推演到了一个完全反直觉的终局：
当 AI 和具身智能把人类在生产力上的最后一滴汗水都彻底碾压之后，劳动的定义本身被击碎了。
过去几千年，人类是通过有用性来确立自我价值的。
你能搬砖、能算账、能写代码、能做报表，你被按月支付薪水，你的尊严建立在社会需要你干活的基础上。
但当 AI 在任何一项具体任务上都比人类做得更好、成本更低时，有用性就不再是稀缺品了。
这时候人类不会灭绝，人类会集体进入一种被迫的退休状态。
就像那些退了休却过得极度充实的老人一样，他们每天早起练字、下棋、养花、钓鱼，没有一件事情是在给社会创造 GDP，但每个人都活得自得其乐。
未来所有的实用性工作，都会被自动化彻底吃掉。
而那些效率最低、最耗时间、最不划算的非标动作，反而会成为人类精神生活里最后的奢侈品。
写一封手写信、亲手烤一块面包、花三个月陪孩子搭一个歪歪扭扭的树屋，这些事情的价值恰恰在于它们是低效的、笨拙的，并且充满了人类自己的真实痕迹。
机器负责解决生存的效率，人类退回生命本身的体验。
所以这里有一个很重要的问题值得我们思考，如果未来你做任何事情都不再能换来超越机器的报酬，你今天真正该想清楚的是：
剥离掉靠打工换来的社会身份之后，你到底靠什么让自己感到快乐？
掌舵红杉资本二十年的 Doug Leone，在访谈里说了句几乎得罪所有同行的话：
风投这行犯过最大的错误，其实不是投错了哪家烂公司，而是太早卖掉了真正的赢家。
他直接摊开了红杉历史上最值钱、也最痛的四笔减持：
红杉曾经持有英伟达 20% 的股份，卖掉了。
他们是苹果的第一位机构投资人，卖掉了。
持有过思科四分之一的股份，卖掉了。
持有过 Google 10% 的股份，也卖掉了。
光是 Google 这一家，如果一股没卖，今天红杉手里的持仓就值 5000 亿美元。
风险投资的传统规则，永远是算账面 IRR、保账面回报率、到了退出期赶紧把现金分给 LP。
只要账面赚了 10 倍甚至 50 倍，全行业都会劝你落袋为安，把战绩锁死在基金年报里。
但 Doug Leone 彻底推翻了这个逻辑：
真正伟大的公司，在 IPO 敲钟之后还会复合增长 20 年以上。
只要你稍微有点商业嗅觉，确认这家公司本质上面对的是一个无限市场，你就绝不应该卖出一股。
以前大家以为赚大钱靠的是不断押中新风口，实际上最恐怖的超级复利全在后面。
把 50 亿美元的收益继续留在场上，它能自动滚成 500 亿美元。
传统风投是用 10 年期的封闭式基金，去生搬硬套一个能跑 30 年的无限滚雪球游戏。
为了锁住眼前的账面收益，亲手把人类历史上最值钱的一批资产拱手送给了二级市场。
这对我们做业务、做技术和做积累也是同一种提醒，
最难的从来不是最初挑对了好方向，而是当好资产开始给你爆发式反馈的时候，克制住自己想要落袋为安的小聪明。
平庸的东西才需要频繁波段，真正能穿越周期的飞轮，拿住就是全部的策略。
当然这个逻辑之所以在红杉身上成立，前提是他们有最顶级的眼光和打破规则的体量，红杉后来甚至特意推翻了成立半个世纪的基金模式做出了永续基金。
对绝大多数人来说，无限市场极其罕见，把平庸资产误当成无限赢家死扛，是更致命的陷阱，
而赚大钱靠的也不是频繁兑现的精明，关键在无限市场里按住自己想套现的手。

Today is my last day at Cal AI.
Less than 3 years ago, I was sitting in meetings I didn't care about, reviewing PowerPoints that didn't matter, and wondering if I was going to waste my entire life never reaching my potential.
Today, I'm walking away from a company that changed my life forever.
It's hard to even put into words what I'm feeling right now.
When we started Cal AI, my goal wasn't to get rich.
I wasn't dreaming about an exit.
I literally just wanted to make enough money to quit my job.
I just wanted to bet on myself, that's it.
I just wanted to wake up every morning and feel like I was actually doing something with my life.
What happened next was beyond anything I could have imagined.
There were 20-hour workdays, weeks where I barely slept, days where I'd lose my voice from spending so many hours on the phone with influencer managers.
I remember spending Thanksgiving coordinating with influencers for a $25,000 giveaway while everyone else was enjoying the holiday.
There were countless moments where my entire life revolved around getting one more creator to post, one more campaign live, one more thing across the finish line.
And I loved every second of it.
Because for the first time in my life, I felt like I was exactly where I was supposed to be.
I wasn't watching the clock waiting to go home anymore.
I was looking at the clock wishing there were more hours in the day.
Fast forward less than 3 years and that simple ChatGPT wrapper has given me things I never thought possible.
I'm financially free.
My family is financially free.
And I'm now in a position to help change the lives of the people closest to me.
All because of an app that lets you take pictures of your food.
Life is insane.
But none of this would have been possible if not for the team around me:
@blakeandersonw you took a chance on me when you didn't have to, and I will spend the rest of my life trying to prove you right.
You're one of the best entrepreneurs I've ever met, but more importantly, one of the best human beings.
You have a heart of gold, and I've learned more from you than you'll ever know.
@henrylangmack you're genuinely one of the kindest and smartest people I've ever met.
You've shown me that you can be an incredible businessman without sacrificing being a good person.
@zach_yadegari I genuinely believe you're going to become one of the greatest entrepreneurs of our generation.
Your ambition is contagious, and I cannot wait to watch you take over the world.
@A1fiedickens15 you are the American dream. Watching how much you've grown has been one of the most rewarding parts of this entire experience. I'm so proud of you, and I know you're just getting started.
Dinesh, Fish and the entire MFP team, words cannot convey my gratitude. Whatever you need from me, for now and forever, I got you covered.
And to everyone else at Cal AI, I owe you more than I could ever repay.
I'd run through a wall for every single one of you.
It's funny.
Three years ago, I was terrified that I was going to waste my life.
Today, I'm terrified I'll never get to experience something quite like this again.
Your entire life can change in a matter of months.
You just have to be willing to bet on yourself. Safest bet you’ll ever make.
Thank you, Cal AI
One last thing: Move fast
P.S. if you want to know what I’ll be working on going forward, check the first comment
🎉🎉🎉
So excited to finally share this.
A huge thank you to @yousuck2020 for leading our pre-seed round and believing in us!!
Thank you to our team, our investors, and everyone who made this possible.
We’re just getting started.

Elon Musk stutters. Not occasionally. Consistently. In almost every interview and public appearance, there are moments where he pauses mid sentence for 3 to 5 seconds, searching for a word that his brain has processed but his mouth cannot produce. The pauses are long enough that interviewers visibly shift in discomfort. The audience holds its breath. The man who runs 6 companies simultaneously cannot always produce the next word in a sentence.
The speaking difficulty is not a performance. It is not a thinking pause (though he has those too). It is a genuine processing bottleneck between his thoughts and his speech. His brain operates faster than his verbal output system can manage. The thoughts are there. The words lag. The lag produces the stutter, the filler sounds, and the long silences that define his public speaking.
As a child in South Africa, the speaking difficulty was more pronounced. He was slow to speak. He was quiet in class. Teachers assumed he was intellectually behind. The boy who was reading the Encyclopaedia Britannica at 9 was perceived as struggling because his verbal output didn't match his cognitive input. The gap between what he knew and what he could say was the first version of a pattern that would follow him for life.
The irony is devastating: the man whose companies depend on public trust, investor confidence, and media communication is physiologically disadvantaged at the one activity that produces all three. Every keynote, every earnings call, every interview requires him to perform the skill his nervous system handles worst. He does it anyway. Poorly. Consistently. Without avoiding it.
He has never used a teleprompter. He has never used scripted remarks. He speaks live, stutters live, pauses live, and recovers live. The refusal to script is not bravery. It is authenticity pushed to a point that makes his communications team visibly nervous. The man would rather stutter through the truth than fluently deliver a script.
The most powerful communicator of the 21st century, the man whose tweets move markets and whose vision has redirected entire industries, cannot always finish a sentence without a 5 second pause. The words don't come easy. They never have. He says them anyway. And the world that watches him stumble through a keynote then watches him land a rocket and concludes that the stumble is what makes the landing believable. The man is not polished. He is real. The stutter is the proof.

Elon Musk's first child, Nevada Alexander Musk, died of sudden infant death syndrome (SIDS) at 10 weeks old. The baby stopped breathing. Justine Musk has described the loss as the moment that changed Elon permanently and irreversibly. He held the baby as it died. And then he went back to work.
Justine has written about the period after Nevada's death with a precision that makes the grief tangible. She described a man who processed the loss by refusing to process it. He did not take time off. He did not go to therapy. He did not sit with the grief. He returned to work and operated at full capacity within days. The external function was uninterrupted. The internal damage was never addressed.
She wrote that when she tried to talk about Nevada, Elon told her that dwelling on things that cannot be changed is not productive. The statement is logically correct and emotionally devastating. The partner who had just lost a child was told by the other parent that discussing the loss was unproductive. The word "unproductive" applied to the death of a 10 week old baby.
They conceived twins through IVF shortly after Nevada's death. The decision to have more children immediately was Elon's. The logic was the same logic he applies to everything: a loss was incurred. The response is to rebuild. Not to grieve. Not to wait. Rebuild. The twins were born 2 years after Nevada's death. The rebuilding was biological. The grief was unprocessed.
Elon has almost never spoken about Nevada publicly. When asked, he gives brief, factual answers without emotional elaboration. The absence of elaboration is itself the story. A man who can describe rocket physics for 40 minutes cannot describe the death of his first child for 40 seconds. The topic is the one system he cannot debug by talking about it.
14 children followed Nevada. Each pregnancy was rapid. Each child was produced with the urgency of someone replacing something that was taken. The question that nobody asks is whether the man who produces children at a rate that exceeds any reasonable parenting capacity is still, at some level, trying to replace the first one who stopped breathing in his arms at 10 weeks.
The grief was never expressed. The children kept coming. The companies kept building. The man who solves every problem by building moved to the next build before the last loss was processed. And 20 years later the loss is still unprocessed because the man who processes everything cannot process the one thing that processing cannot fix.

「3年後にAGIが誕生すると分かっていながら，博士号を取り，ポスドクになり，大学教授になる計画を立てているんですか？」
Anthropicの研究者が，博士課程の学生たちに「あなたたちのキャリアプランはもう存在しない」と告げた講演が話題です。
拡散モデルの発明者でもあるJascha Sohl-Dickstein氏（Anthropic）の講演『Advice for a young investigator in the first and last days of the Anthropocene（人新世の最初と最後の日々における若手研究者へのアドバイス）』を紹介します。
youtube.com/watch?v=3LZN2UUx…
人類が主役だった地質年代（人新世）が，AIの台頭によって極めて短い期間で幕を閉じるかもしれない ——そんな前提のもと，提示されたデータは強烈です。
■ 突きつけられた冷徹なファクト
モデル訓練の計算量は過去10年で約1000万倍に増加し，人間の脳が生涯で行う総計算量に迫っている。AIが単独で完遂できるタスクの時間スケールは，数ヶ月ごとに倍増している。ここ7ヶ月ほど，モデルは数学者が長年解けなかった未解決の「Erdős（エルデシュ）問題」を解き始めている。サンフランシスコでは「長いタイムライン（懐疑派）」とは「AGIは10年以内に来る」を意味している。2030年の計算量は2025年の約1万倍に達する見込み。
線形グラフで見れば，現在の劇的な進歩すら「まだゼロと区別がつかない平坦な初期段階にいる」というのが彼の主張です。
■ 学生たちへのシンプルで容赦ないアドバイス
毎日AIを使え。指数関数の上にいれば，遅れを取ることはない。彼自身はClaudeを「実行力は天才だが、研究のセンスはかなり悪い大学院生」のように毎日使い，自分ではもうコードを一切書いていない。
計算量がスケールするほど良くなるプロジェクトを選べ。それ以外は，完成する前に解かれてしまう サットンの『苦い教訓』の通り，スケールに味方されるテーマを選ばなければ，2年かけた研究も完成する頃には次世代モデルのプロンプト一発で追い抜かれる。
キャリアを「安定したもの」として計画するのをやめろ。安全な選択肢は，もはや安全を買ってくれない 社会全体で大規模な破壊が起きるなら，ベースラインのリスク自体が高い。従来の「手堅い選択肢」は，もはや安全を担保してくれず，ただ潜在的なリターンを犠牲にするだけになる。
そして，最も印象的な一言がこれ。
「書くことは考えることだ（Writing is thinking）。書くことを外注すれば，考えることも外注することになる。」
コーディングや実行は徹底的にAIへ委譲しつつ，問題設定（センス）と思考の核（書くこと）だけは決して手放すな。 AGIのタイムラインを本気で信じているなら，キャリアの計画も本気でそれに合わせろという，極めてストレートなメッセージの講演を紹介しました。

If you LACK MOTIVATION as an app builder, read this
Pre-app (app not released yet):
You have taken the decision 99% in this world didn't: start entrepreneurship. You are ambitious and driven, you see all these 9-5 zombies around you and you refuse to follow the same path. Whether you just want money, or actually want to do something good for the world, you know your destiny lies in owning your own business. Money is power and money moves people. Be proud that you made the decision to start in the first place, 99.99999% didn't. You refuse to accept being mediocre. It's time to take action, endless thinking is your biggest obstacle here. Just DO something, anything, organize yourself. Brainstorm, plan, and execute. Set a rough deadline for yourself, like 3 months of app building until you decide whether you want to continue or not. But one thing is for certain, you are very ambitious at this stage and are willing to step in the unknown. This is commendable. You can be proud of yourself.
App released, $0 MRR:
You finally released your app. Most people are stuck engineering their app endlessly because they feel more comfortable with building than marketing. It feels vulnerable to open up to the world, but you realize you have to. You have to prioritize marketing and releasing a quick MVP. Without marketing, your masterpiece remains hidden from the masses. Very few people understand this like you. It's time to start spamming TikToks, monitoring the first little data that comes in and learn more about social media. Look at the 5 downloads you get per day, these are 5 real humans who took an interest in your app. Look at their behaviour, see where they dropped off in the onboarding and keep optimizing until you hit your first paying customer. Your first paying customer is inevitable with a good onboarding and a hard paywall. But the fact that you are getting any downloads at all should always be celebrated. These are real humans!
$1 - $2000 MRR
By far the most people quit here. This is the stage where you have to prove that your app is worth time and investment. You are making real money for the first time from something you thought was fictional a couple months ago. It's time to gather as much data as possible. Then, look at the data and see if this app is worth scaling. You realize you can only go so far with marketing organically. You need to invest money to make more money. Either through ads, UGC or some sort of automation. This phase starts to challenge you, because for the first time in your life you have to rely on factors outside of yourself. You realize you cannot do everything by yourself, a one-man-army is a weakness. The end of this the phase is where you start learning to think in systems and scale. This is the phase where you have to let go more, and step outside yourself. Put your ego aside and let the systems or freelancers do the work for you. It will be tough, but you already came so far. If you realize this, it's hard to believe you will stop here.
$2001-$9999 MRR
You started thinking in systems and created an infrastructure with ads, an automation system, a farm or a small UGC campaign. Look at what you've created; a whole ecosystem designed to turn $1 into $10. You understand consumer apps well, all that's left is to put more money into your system, optimize your funnel to perfection, experiment with more creative formats, and hit virality more consistent. Usually you have to pour in more money to oil the engine, but one thing is for sure, your app is a proven idea if your MRR is consistently above $2000. This is also the first time where your internet money feels real. It gets close or even surpasses your supposedly full-time job, especially in non-western countries. You start hating Revenuecat, you start hating Apple, you start hating Google and any middle-man taking a cut % of your revenue. You realize how large the difference between revenue and profit. You probably are writing contracts, tax forms and P/L statements for the first time. You are stepping in a whole new world inaccessible to the commoners, and it's inevitable that you will hit $10,000.
$10000+ MRR
If your MRR is consistent here, you belong to the elite, and realistically 99.9% will not get here. You are a real entrepreneur now and it's not just a small hobby anymore. Your parents and friends now see you as a big deal. People have massive respect for you, and now it's time to help other people too. X warps your perspective sometimes still, seeing so many people hit 100K MRR but remember this is social media. You keep comparing yourself with the finest entrepreneurs. Many people are frauds on here too, so comparing yourself with them is unfair to you. Be proud of what you have achieved. $10,000 MRR gives financial freedom in every country. Treat yourself on a holiday if you haven't already. Most advice including mine will not help you anymore and you probably have to look for advice from the 100K MRR legends. Either well, I'm happy you're here. If you are at this stage and you are not happy with your life, something is SERIOUSLY WRONG with you. You probably are too focused on material desires, and you should start thinking of your greater purpose in life; of what you actually want to do with so much money. You start realizing that money does not bring satisfaction in itself. If you are not happy at 10,000 a month, you wont be at 100,000 either. Keep it up, nothing can stop you at this point
