Hi HN

I built Video Forms: a tool that lets you attach questions to specific timestamps in a video, optionally with branching/skip logic.

Motivation: I kept getting “looks good” feedback on demo/onboarding videos, but the useful feedback was always “at 0:42 I got confused” — and it was hard to collect that in a structured way. Surveys lose context; comments are unstructured.

How it works (high level): - You create a “video form” by placing questions at timestamps (e.g., 0:18, 0:42) - The video can pause to ask the question, then continue - Answers can branch to different follow-up questions based on responses - You get responses tied to the exact moment in the video (and can export/share results)

Use cases I’m aiming at: - UX research on product demos - Onboarding: “did this step make sense?” checks - Training/L&D comprehension checks

I’d love feedback on: 1) What question types would you need first (free text, multiple choice, rating, etc.)? 2) Is “interrupting” the video a deal-breaker, or does pausing at key moments feel acceptable? 3) Any workflows/tools you’d want this to integrate with?

Hi HN — we recently launched the Berkeley Xcelerator (https://rdi.berkeley.edu/xcelerator), a non-dilutive accelerator program run by Berkeley RDI (https://rdi.berkeley.edu/) for pre-seed and seed-stage teams building in AI and agentic AI. We’d love to get some feedback from the community!

Over the past three years, Berkeley Xcelerator has supported 110+ teams across AI, cybersecurity, and decentralized technologies, whose founders have gone on to raise $650M+ in follow-on funding, spanning 100+ countries.

Some concrete details about the Xcelerator itself:

- The program is non-dilutive (no equity taken)

- Open to pre-seed and seed-stage AI / agentic AI startups

- No UC Berkeley affiliation required

- Selected teams receive support through Berkeley RDI’s research community and ecosystem partners

- Enablement includes cloud, GPU, and API credits from industry partners (including Google Cloud, Google DeepMind, OpenAI, and Nebius, with more to be announced)

- The program culminates in a Demo Day at the Agentic AI Summit (Aug 1–2, 2026) at UC Berkeley, where we are expecting 5,000+ in-person attendees

Here’s what we’d really like input on:

- If you’ve built or joined an early AI startup, what actually helped you most early on?

- If you’ve done an accelerator, what helped and what was a waste of time?

- For technically deep projects (infra, agentic systems, safety-sensitive work), what kinds of feedback or structure mattered most before product-market fit?

If you’d like to apply to the Berkeley Xcelerator, applications are open through the end of February. (https://forms.gle/KjHiLAHstAvfHdBf7)

Is there an alternative to HN out there where I can read threads and see people actually discuss developments in AI in a positive, mature way? I just fired open the GitHub founder's one (https://news.ycombinator.com/item?id=46961345) and the comments are all "I hate they way they said it" or "It's useless" or, of course the opposite "Pff, I do that already". I'm sort of sick of this empty excuse for debate. Is it just /r/LLM or something? Where are the intelligent debaters hannging out?
