re: your ML eng post on Hacker News

Hey Sarah,

Your post about building Acme's recommendation engine from scratch got mass upvoted for a reason. Most teams would have fine-tuned an off-the-shelf model and called it done. You rebuilt the entire embedding pipeline instead.

We just helped a similar-stage team (post-Series B, 40 engineers) cut their ML hiring cycle from 62 days to 19. Happy to share exactly what they changed.

Want me to send over the breakdown?

Subject: saw your 5 new sdr hires

Hey Sarah,

Noticed Acme just brought on 5 SDRs — scaling the outbound motion post-Series B is the right move. The tricky part: ramping them before your board expects pipeline numbers.

We built an AI coach that cuts SDR ramp time from 3 months to 6 weeks (Lattice and Notion both hit quota 40% faster). Worth a look?

Frequently Asked Questions

How does SpearFisher personalize cold emails?

SpearFisher uses AI to analyze prospect information you provide — LinkedIn profiles, company details, recent news, tech stack, and more — then generates three personalized email variants using different persuasion angles: direct value, curiosity hook, and social proof.

Is SpearFisher free to use?

Yes. The free tier gives you 5 personalized emails per month with basic personalization. Pro ($49/mo) gives you 200 emails with advanced personalization including company news, tech stack detection, and hiring signals.

What reply rate improvement can I expect?

Personalized emails that reference specific prospect details consistently outperform generic templates. SpearFisher helps you craft emails that show genuine research, which prospects notice.

How is SpearFisher different from email templates?

Templates are static — every prospect gets the same email with a name swapped in. SpearFisher researches each prospect individually and generates unique emails that reference their specific company, role, recent news, and pain points.
