B150

B150 is a professional social network for Gen AI builders and creators, positioned as "the LinkedIn of AI". It welcomes only people who actually build products, not lurkers chasing visibility. Its core creed is "not a resume, a receipt of shipped work": member profiles are built on publicly delivered projects. It is currently in free beta, built solo by its founder through vibe coding in 3 months for roughly $260.

Core capabilities

• Post: Share projects publicly and get real feedback from early beta users and peers
• Feed: Track in real time how other builders solve problems — "a community feed with no noise"
• Network: Build genuine connections through "deliver, share, show up", with strong-connections-only filtering
• Profile: Prove AI expertise with shipped projects instead of resumes, with peer review maintaining quality
• Jobs & Talent: Free and sponsored job postings ($299/30 days), expert placement from $185/hour
• Marketplace: Discover AI tools and discounts, including weekly sentiment analysis

Use cases Vibe coding founders, creative professionals such as AI filmmakers and designers, AI entrepreneurs looking for early users and co-founders, and corporate recruiters who need AI talent. If you ship fast with Cursor, Lovable, or v0 and are willing to show your work, this is home turf.

Unique advantages Unlike LinkedIn's resume-and-title system, B150 centers its profile mechanism on "proof through shipped work", directly attacking performative content and resume inflation. Compared with the offline-focused AI Tinkerers, it is a purely online product; compared with the similarly positioned TensorHQ, its talent placement plus tool marketplace forms a closed-loop business. The founder's "3 months, $260" founding story is itself the strongest endorsement.

Editorial verdict The idea is persuasive and official operations stay consistently active (weekly Jobs/Events, Vibeathon hackathons), making it a low-cost ticket into understanding AI-native community trends. But be clear-eyed: roughly 4K monthly visits, scarce independent word of mouth, and real cold-start and retention risks. Overall rating 3/5, best suited to builders and recruiters participating in the early ecosystem; those wanting a mature community can watch TensorHQ instead.
