The 5 words that kill YC applications:
- "Proprietary algorithm" (what does it do?)
- "First-mover advantage" (meaningless)
- "Viral growth" (how?)
- "No competition" (impossible)
- "Huge market" (show your own math)
Replace each with something specific. Your application will be unrecognizable in the best way.
We’re opening a research preview of Claude Duet, a new app where Claude works as a proactive agent.
It comes to you with what needs your attention, completes tasks you ask of it, keeps working when you step away, and checks with you before it acts on your behalf.
The "research phase" trap that delays YC applications forever:
"We're still doing customer discovery."
After 6 months.
Customer discovery should take 4 weeks. Not 6 months.
20 conversations. Write down the patterns. Pick the most painful. Build the minimum thing.
The founders stuck in "research phase": are usually avoiding the moment when the market tells them if they're right or wrong.
We're making Shopify's mobile apps self-healing.
Agents watch production 24x7 for new crashes, reproduce them, write and verify a fix, then generate a short video explaining the root cause and the fix. Much faster to digest than the usual wall of text.
An engineer then just reviews and ships it.
Nice code review idea I’m seeing more teams adopt: Classify changes.
If it’s low risk, just do automated review.
If it’s high risk, then require 1-2 humans to review.
Claude writes about 90% of Claude Code's code.
From June to September, merged PRs more than doubled while the share reverted fell by more than 40%.
We wrote about how we changed code review to get there, and how to adopt it:

We keep improving performance across Claude, and you may have noticed it starts responding sooner!
Claude Code now gzips the conversation it sends on every turn, so it reaches the model faster. Cloud sessions also start up as soon as you start typing.
Today we’re releasing Muse Spark Open, the most capable US open-weight model to date.
Built for coding and agentic work, it excels at long-horizon tasks, complex software engineering, and multi-step reasoning.
Key Model Specs:
→ 816B total / 42B active parameters
→ 1M token context window
→ Natively multimodal across text, image, video, audio
