I emailed zero of my competitors' angry reviewers. Their reviews still got me 10 leads: A bad review tells you exactly what's broken. So I use the complaint, not the person. Last run: 240 reviews in, 10 leads out, 15 minutes. ━━━━━━━ 𝟭. 𝗠𝗶𝗻𝗲 𝘁𝗵𝗲 𝗰𝗼𝗺𝗽𝗹𝗮𝗶𝗻𝘁𝘀 → recent 1 to 3 star G2 reviews of my competitors → sorted into what people hate: price, bugs, support ━━━━━━━ 𝟮. 𝗙𝗶𝗻𝗱 𝘁𝗵𝗲 𝗯𝘂𝘆𝗲𝗿𝘀 → sales leaders at companies that fit my market and show a buying signal, like hiring sales reps → never the people who wrote the reviews ━━━━━━━ 𝟯. 𝗦𝗰𝗼𝗿𝗲 𝗮𝗻𝗱 𝗵𝗮𝗻𝗱 𝗼𝘃𝗲𝗿 → every lead scored out of 100, 9 of 10 with a verified work email → one draft email per lead, built on the pain it matches ━━━━━━━ I built it on Twin. Five questions in, a scored list out. Run it here: https://lnkd.in/drGSM8JM

Spotify cut Claude Code token usage by 90%. Here's what I got when I tested it: Their trick: a cheap model does the reading and the boilerplate, and a hook blocks Claude from opening any file over 350 lines. I rebuilt it for Claude Code with Haiku, then ran 4 real tasks on a real codebase, with and without it. ━━━━━━━ ☑ 𝗧𝗵𝗲 𝗯𝗹𝗼𝗰𝗸 𝗻𝗲𝘃𝗲𝗿 𝗳𝗶𝗿𝗲𝗱 → 0 blocked reads in 4 tasks. → without the setup, Claude read big files in full in 2 of them. With it installed, it searched and read sections instead. Nothing left to block. ━━━━━━━ ☑ 𝗧𝗵𝗲 𝗰𝗵𝗲𝗮𝗽 𝗿𝗲𝗮𝗱𝗲𝗿 𝘀𝗮𝘃𝗲𝗱 𝗻𝗼𝘁𝗵𝗶𝗻𝗴 → Claude never called it. it always found a cheaper path on its own. ━━━━━━━ ☑ 𝗧𝗵𝗲 𝗰𝗵𝗲𝗮𝗽 𝘄𝗿𝗶𝘁𝗲𝗿 𝗽𝗮𝗶𝗱 → writing a type file from a 1,184-line module: $0.82 down to $0.59, Haiku included. → better result too: 51 of 57 functions covered, against 42. → the catch: 3x slower, and on a test-writing task it cost more and did worse. ━━━━━━━ I'm giving away the full setup, ready to install in Claude Code: https://tally.so/r/RGAVMK

I fed Claude 200 YouTube videos on sales and GTM. It came back with 10 skills: The 20 most-watched videos on each topic, turned into a skill Claude uses every time you ask. ━━━━━━━ ☑ 𝗖𝗼𝗹𝗱 𝗲𝗺𝗮𝗶𝗹 → writes emails that lead with something free ☑ 𝗖𝗼𝗹𝗱 𝗰𝗮𝗹𝗹𝗶𝗻𝗴 → scripts openers that sound calm, not salesy ☑ 𝗟𝗶𝗻𝗸𝗲𝗱𝗜𝗻 𝗗𝗠𝘀 → writes openers from the prospect's own posts ☑ 𝗗𝗶𝘀𝗰𝗼𝘃𝗲𝗿𝘆 𝗰𝗮𝗹𝗹𝘀 → preps questions that dig past the first answer ☑ 𝗢𝗯𝗷𝗲𝗰𝘁𝗶𝗼𝗻𝘀 → handles them before the prospect raises them ☑ 𝗙𝗼𝗹𝗹𝗼𝘄-𝘂𝗽𝘀 → never sends "just checking in" ☑ 𝗣𝗼𝘀𝗶𝘁𝗶𝗼𝗻𝗶𝗻𝗴 → narrows who you're for until it's obvious ☑ 𝗣𝗿𝗶𝗰𝗶𝗻𝗴 → prices the outcome, not your time ☑ 𝗟𝗶𝗻𝗸𝗲𝗱𝗜𝗻 𝗰𝗼𝗻𝘁𝗲𝗻𝘁 → turns your ideas into posts that take a side ☑ 𝗟𝗲𝗮𝗱 𝗺𝗮𝗴𝗻𝗲𝘁𝘀 → builds offers around one real customer problem ━━━━━━━ Same method works on any topic. 20 videos in, one skill out. All 10 skills here: https://tally.so/r/NpaOLW One video gives you an opinion. Twenty give you the playbook.
