one filter i’m using for saas ideas: what does this problem already cost the customer? if the answer is “not much,” it’s probably going to be hard to sell. #buildinpublic

Please hear my advice: - YC won't accept you (low chance) - Your startup (probably) won't go viral - VCs won't chase you - TechCrunch won't write about you - No one is going to save you (sorry) Build your product as if NONE of those will happen. That will be more helpful.

what’s harder for a solo founder: building the product or finding the first 10 users?

where i’d look for my first 100 users: - reddit for honest feedback - x for building an audience - linkedin for b2b leads - hacker news for technical users - product hunt when the product is ready you don’t need every channel. you need the one where your users already are.

i tested 5 model + agent-harness setups on 3 blind security labs: ocdeep - opencode + deepseek v4 pro glmcode - claude code + glm-5.2 ocglm - opencode + glm-5.2 kimicode - kimi cli + kimi k2.7 code ockimi - opencode + kimi k2.7 code Every setup received the same prompts and benchmark conditions. No benchmark-specific hints or known solutions were provided. all got 3/3 exact. winner: ocdeep (opencode + deepseek v4 pro) - 20m31s, $0.14, 97/100 One of the clearest takeaways: the harness mattered almost as much as the model. the same model produced meaningfully different results depending on the agent wrapper.

i got tired of security agents forgetting everything between hunts, so i built a local second brain in obsidian for cybersecurity (bug bounty + pentesting): 1,310 notes 13,649 links 492 security techniques 250 portswigger lab solutions 84 CVEs 48 security writeups 37 PoCs 45 methodologies + playbooks 19 of my own real bug bounty reports the graph looks cool. the value is knowing what worked, what failed, and where every claim came from. next test: same agent, same test - brain vs no brain.
