Attie is a standalone AI assistant built on the AT Protocol and powered by Anthropic's Claude, released by Bluesky's former CEO Jay Graber — who stepped down specifically to build it. The app lets users design custom social feeds using natural language, without writing a single line of code. You can ask Attie to surface posts about specific topics, filter out content you hate, or create algorithm-driven feeds for any niche interest. Because Bluesky runs on the open AT Protocol, Attie has immediate access to your social graph, interests, and interaction history across the entire ecosystem — not just Bluesky but any ATProto app. This gives it a contextual richness that proprietary AI assistants like Grok (X) or Meta AI can never achieve on their platforms. It's invite-only with a waitlist, but the longer-term plan is to let users vibe-code their own social apps. The early reception was fascinating: Attie became the most-blocked account on Bluesky after Bluesky's own announcements bot — suggesting meaningful user anxiety about AI intrusion in the open social graph even when the tool is explicitly opt-in.

Avina is a Y Combinator-backed GTM agent platform for B2B sales teams. It defines your Ideal Customer Profile, then continuously tracks buying signals across the web, LinkedIn, and job postings to surface in-market prospects. Dynamic audiences refresh daily without manual list building, and the system runs personalized AI email campaigns and ABM sequences on identified targets. The platform is designed to replace the fragmented stack of prospecting tools — Clay, Apollo, Outreach, and similar — with a single agent layer that handles the entire top-of-funnel workflow autonomously. The signal tracking layer is particularly differentiated: rather than static lead lists, Avina monitors job postings, funding announcements, and web content changes to time outreach to buying moments. With YC backing and a tight go-to-market focus on autonomous sales prospecting, Avina enters a crowded but rapidly consolidating category. The teams that figure out AI-native GTM motions in 2026 will have structural cost advantages over those that don't.
Reviewer scorecard
“The AT Protocol's open data model is the unlock here — Attie can see your entire social context across apps, which is something a walled-garden AI assistant fundamentally cannot do. This is the right architecture for personal AI at the social layer.”
“The signal-based dynamic audiences are the real differentiator here. Static lead lists decay fast — knowing that a company just posted three DevOps roles and triggered your ICP is actionable in a way that a CSV from Apollo isn't. The YC stamp means the team is likely iterating fast.”
“The most-blocked-account stat tells you everything — even Bluesky's ideologically aligned user base is spooked by AI having read access to their social graph. Invite-only with no clear monetization path suggests this is a feature, not a company.”
“The AI SDR category is getting extremely crowded — Artisan, 11x, Amplemarket, Clay, and dozens of others are all racing to the same 'autonomous prospecting' positioning. Deliverability challenges with AI-generated email are also intensifying as enterprise spam filters get smarter at detecting agent-written copy.”
“This is the first demo of what AI-mediated social looks like on an open protocol. If it works, the implication is that any user can have a completely personalized feed without relying on corporate algorithmic decisions. That's a genuine paradigm shift from Twitter/Instagram's engagement-optimized black boxes.”
“B2B GTM is one of the highest-value, most automatable workflows in business. When AI agents can monitor the entire web for buying signals in real time and act on them faster than any human SDR team, the competitive moat shifts from headcount to ICP precision. Avina is building in the right direction.”
“As a creator, controlling your own feed algorithm without needing to understand engagement optimization is huge. Being able to say 'show me posts from small illustrators, no sponsored content, heavy on process videos' and just getting that — this is the tool I've wanted since RSS died.”
“As a creative professional, I find AI-generated sales outreach increasingly easy to identify and tune out. The quality of personalization matters more than the quantity of signals. Avina will need strong content generation capabilities to avoid the 'obviously automated' problem that plagues most AI sales tools.”
