ProvenMetal is pitching faster PCB assembly for hardware teams, including upstream feedback on bills of materials and lead-time alternatives.
The thread welcomed the ambition but warned that domestic assembly, component sourcing, and price competition are the hard constraints—not the upload form.
The top HN threads: facts from the discussions, both sides, insider voices. Email, Telegram, or RSS.
The frontend weighs 6.42 MB across 169 requests; Hacker News, also run by YC, serves its homepage in seven requests and 12 KB. The auditor, Gregorein, confirmed the whole list by feeding the files to a single Claude session.
That is where the thread turned on the auditor: anyone with a Claude subscription could run the same check, several noted, and Fast Company's own page pulls 29 MB over 300+ requests. The critique that outlived the pile-on wasn't about the bloat at all. It was about measuring work in lines of code.
Papermark, the open-source DocSend alternative, went public on X accusing a YC-backed founder of passing off its AGPL code as a fresh "vibe coded" product, demanding the data room come down as license-infringing fraud.
The thread split fast. Some pointed out you can't "steal" open source if you keep the license; others noted AGPL forces you to publish your own source the moment a user touches it over a network. The screenshots showed whole pages copied verbatim, design and text.
The maker pitches AI agents plus community contributions and an 'agent ledger'. Commenters found stale figures, missing companies and badges that link to nothing.
The most useful fix offered: federate with Wikidata, which would pull in connections back to Crunchbase and other sources for free.
Adam's open-source core, CADAM, wraps Claude (with OpenAI/OpenRouter fallback) around OpenSCAD compiled to WebAssembly: describe a part, get parametric code with auto-generated sliders. Parameter tweaks skip the LLM via a regex edit on the source.
The benchmarks lead with a V8 engine and a turbofan. "That's a lie," wrote an embedded engineer — "a bunch of boxes with no fasteners to hold them together." Another user fed it a real part number and got wrong pitch, wrong pin positions, missing pins.
Graham frames the billion as pure exponential math: growth rate times market size, and "it will happen automatically if you just keep making customers happy." His honest-earner examples are Airbnb, Apple, Facebook.
The sharpest pushback wasn't outrage but bookkeeping. Creative destruction credits the creation and quietly writes off the destruction, one engineer argued. Another did the YC math back at him: out of ~6,500 funded, about 30 billionaires, under 0.5%.
You change only your connection string, not your app. The open-source version has 1.4M Docker pulls; the round is from Basis Set, YC and Pioneer Fund.
Simon Willison's request was the most telling product feedback: ship a plain binary, because he won't fire up Helm or Docker just to kick the tires.
