SignalDeal
Automate B2B research & write emails in seconds
What it does
SignalDeal solves the manual research bottleneck in B2B sales. Instead of spending 15 mins/lead checking websites, it automates the technical detective work. It scans prospects' URLs in bulk to detect real pain points—like missing pixels, slow speeds, or broken tags—and turns those errors into high-converting, data-driven icebreakers. Stop sending generic spam. Start sending relevant emails at scale. I built this to replace my manual grind and saved 41 hours this month alone.

There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
