🕹 Technology Customer success SaaS Artificial Intelligence Startups Enterprise Software Product Strategy
  1. Forward-deployed engineering is everywhere in AI now: engineers are working closely with customers to deeply customize agents, but this model is essentially advanced sales engineering and doesn’t make sense for low-value deals.
  2. AI buyers pay for work, not just access, so building useful agents requires significant customization and expert technical time to pull the right data at the right time rather than a one-size-fits-all product.
  3. Customer success has to move faster and act like a partnership; companies must choose between self-serve onboarding for simple, high-volume customers and white-glove engineering for complex, high-value customers, and prove value month-to-month to keep trust.

🔮 Crypto Investing Regulation Mining Economics Markets
  1. Bitcoin halving happens every four years, cutting miners' rewards in half. This can make mining less profitable for some, but it might also lead to higher Bitcoin prices in the future.
  2. Historically, each Bitcoin halving has led to a price increase, as fewer new Bitcoins are created and demand usually stays the same or increases. This basic economic principle suggests prices could go up when supply decreases.
  3. Several factors, like investor trust and regulatory changes, affect how the next halving might impact Bitcoin and the broader crypto market. Positive developments could lead to a crypto boom.

Generating Conversation • 70 implied HN points • 08 Jan 26
💼 Business AI Data Centers Acquisitions Startups Investment Infrastructure Applications
  1. Big investments in data centers and GPUs are likely to pay off as inference gets cheaper and more AI applications become economical, so infrastructure buildout is a bullish trend.
  2. Large companies will keep acquiring startups and doing acqui‑hires, and those acqui‑hires can harm the startup ecosystem and spook talent unless policy or enforcement changes.
  3. Frontier labs will move up into higher‑margin applications, so startups must differentiate on orchestration, workflows, and solving harder domains like healthcare, security, and SRE where adoption is slower but more defensible.

Secular vs Cyclical: Why it’s hard to tell in real time, and what the EV write-down wave reveals

Gad’s Newsletter • 20 implied HN points • 16 Feb 26
💼 Business Regulation Corporate Finance Strategy Automotive Accounting Investment
  1. It’s very difficult to tell in real time if a change is secular or cyclical because data are noisy, trend-cycle methods are model-dependent, and endpoint uncertainty makes conclusions fragile.
  2. The EV episode shows the direction is likely secular (battery costs and adoption tend to rise) but the speed is cyclical and policy-sensitive, and treating near-term pace as linear led to huge write-downs and competitive losses.
  3. The practical fix is disciplined triangulation and decision design: separate direction from speed, check cross-sections and policy regimes, treat impairments as stress tests, and prefer staged, flexible investments that preserve optionality.
