When mobile game ad revenue drops, it is tempting to open the ad dashboard and check one number first: eCPM. If eCPM is down, it feels like the answer is obvious. Demand is worse. The network is paying less. Maybe the mediation setup is broken. But in practice, eCPM alone can be a misleading first signal. For small mobile game and app teams, the better question is: Which driver actually changed f…

When DeepSeek launched V3 at $0.27 per million input tokens, the developer world collectively did a double take. At the time, GPT-4o was charging $2.50 per million input tokens — roughly 9x more. Today, the gap has widened further. Chinese frontier models routinely operate at $0.10–$0.50 per million tokens while their Western counterparts hover at $2.00–$15.00. This isn't a temporary discount str…

The “5-minute market” concept is gaining attention because of how fast new prediction rounds appear and how quickly volume builds up. Each cycle is short, which creates both opportunity and risk for anyone trying to analyze or trade it. In this article, I’ll break down how I’ve been approaching this space from a data perspective, how I’m thinking about building an edge, and the tools I’ve been ex…

The $0.14-per-million-token Question In June 2026, calling GPT-4o costs $2.50 per million input tokens. DeepSeek V4 Pro charges $0.14. That's not a typo — it's a 94.4% discount. And it's not just DeepSeek. GLM-4.5 runs at $0.10/M. Qwen-3-235B sits at $0.20/M. The Chinese model ecosystem has converged on pricing that makes Western frontier models look like luxury goods. The reflexive explanation i…

Naver Brand Search returns 5×–9× LTV:CAC on every Korean D2C account I operate. It also tells me almost nothing useful about growth. You're not acquiring customers there — you're recapturing people who already decided to buy. Counting it as an acquisition channel inflates your portfolio average and makes cold prospecting look broken by comparison when it isn't. The 3× LTV:CAC rule is a VC heurist…

You pay an affiliate 30% for referring a customer. Three weeks later that customer refunds. Now the affiliate is holding a commission on a sale that no longer exists, and you have to decide what happens to that money. If you only thought about this after it happened, you have already lost the clean version of the fix. I build affiliate software on Stripe, and the clawback case is the one teams sk…

This article was originally published at https://saastools.corenk.com/articles/are-reduce-saas-churn-rate-or-not You closed the month at $14,730 MRR. On the 1st, $1,210 quietly walked out. But you’re not panicking — the logo churn rate dipped from 9.2% to 6.8% last quarter, and the dashboard shows green. The problem? Net revenue churn barely budged from 8.1% because downgrades and failed payment …

What Happened US and Iran a…

This year will go down in history as the year a person became a trillionaire for the first time—on paper, at least. Elon Musk’s net worth catapulted to this unprecedented height thanks to the spectacular initial public offering of his company SpaceX. Putting the moral, social and economic consequences of a single person amassing so much capital aside, how we conceptualize Musk’s wealth reveals hu…
