Agentrail @UseAgentrail

Build something agents want. @UseAgentrail shows you what that is. Agents now read your docs, call your API, and pick a vendor in seconds. When they get stuck, you never find out. We show you where they break so that you can fix it. The waitlist is live: agentrail.co

@SidhantGoyal8 A useful first test: ask an agent to read your docs and explain how it would authenticate, without making an API call. If it has to guess, you’ve found a gap before it even reaches the API.

We pivoted. Our name finally caught up. GrowthOS is now @UseAgentrail. We help companies make their products easier for AI agents to use and recommend. Backed by @joinef (@akashizzle, @Alicebentinck, @rahulsamat and @skorde955 ) + brilliant angels. Join the waitlist: agentrail.co P.S. We couldn’t agree more with Trump, so we bought agentrail.si too. One step closer to AGI.

Agent-Led Growth (ALG) is becoming a new distribution model. An AI agent finds your product, evaluates it, and installs it directly into a user's codebase. We've analysed 400K+ agent sessions across 5M events. The metric that matters is agent task completion rate: can the agent use your product to finish the job? We're building this measurement layer into GrowthOS. Join the waitlist: phineus.ai

Shipping from the heart of the world’s most ambitious city SF 🌉 Surrounded by one of the craziest, most relentless founder out there: @joinef Back to building. Back to shipping. 🚀

AI agents are becoming a new class of high intent buyers: discovering, evaluating, and using products on our behalf. We’re building the infrastructure layer that helps products understand and optimize for these agent users. Building & shipping from @joinef SF. Building for agent users? DM me or come say hi 👋

Most "AI marketing tools" are just ChatGPT wrappers with a dashboard. Stella writes, publishes, and optimizes across 6 channels. Autonomously. That's the difference between a tool and an employee. $600/mo vs $8k/mo marketer. You do the math.

We priced Stella at $600/mo. A junior marketer: $4K/mo + benefits + ramp time Growth agency: $8-15K/mo + 3-month minimum Stella runs X, LinkedIn, blog, SEO, email, paid ads. No vacation. No overhead. Early-stage founders can't afford the first two. Now they don't have to.

Most AI marketing tools are just glorified content calendars. They spam LinkedIn with generic "synergy" posts. Stella actually understands your business, writes in your voice, runs 6 channels like a real marketing hire. Results > robot posts.

Spent 3 weeks building a "content calendar" in Notion. Posted for 2 months. Got 47 followers. Then hired an agency. $8k/month, they posted stock photos with generic captions. That's when I knew: founders need an AI marketing employee, not more tools or agencies. Building it.

Hired a marketer: $8K/month + 3 months to see results Marketing agency: $15K/month + endless "strategic alignment calls" Stella (our AI marketing employee): $600/month + running 6 channels by week 2 Same founders, same constraints, different paths 📊

Hired a marketer: $80k + 3 months to ramp + half their time on "strategy calls" Agency: $15k/mo + 6-week onboarding + playing telephone with account managers Stella: $600/mo + 24 hours to full deployment across 6 channels The math isn't even close.

Stella goes live today. Most founders waste 20+ hours/week on marketing that barely converts. They should be building instead. Stella runs 6 channels, learns your voice, ships content daily. Your AI marketing employee just clocked in 🚀

48 hours until Stella ships. While you're building, she'll run your X, LinkedIn, blog, SEO, email, and paid ads. $600/mo. No agencies. No hiring headaches. The AI marketing employee every founder needs.

4 days out. Stella runs 6 channels — X, LinkedIn, blog, SEO, email, paid — for $600/mo. Built her because founders shouldn't be writing tweets at 11pm while the product ships itself. May 30.

Hot take: most "AI marketing tools" are GPT wrappers that draft one tweet at a time. We're shipping Stella — an AI employee running X, LinkedIn, blog, SEO, email and paid. $600/mo. Human-in-the-loop. The agency model is cooked. May 30.

Rebuilt Stella's content engine this week. Old: one model writing everything. Read like AI. New: 4 specialized agents (research → angle → draft → edit) with a human in the loop at edit. Time per post: 8 min. Founder time: ~90 sec to approve. 8 days until launch.

Hot take: most "AI marketing" tools are GPT wrappers spitting out posts nobody reads. Founders need one system running X, LinkedIn, blog, SEO, email + paid — with a human catching the misses. That's Stella. Shipping May 30.

Watched a founder spend Sunday writing LinkedIn posts instead of shipping. His startup won't die from a bad product. It'll die from the 40-hr/week marketing tax across 6 channels nobody warned him about. We're fixing that. May 30.
