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 @join_ef (@akashizzle, @Alicebentinck, @rahulsamat and @skorde955 ) + brilliant angels.

P.S. We couldn’t agree more with Trump, so we bought https://t.co/XQmouKNJUd 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.

Shipping from the heart of the world’s most ambitious city SF 🌉

Surrounded by one of the craziest, most relentless founder out there: @join_ef

Back to building. Back to shipping. 🚀

[Sidhant Goyal @SidhantGoyal8]

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 @join_ef SF.

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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 📊

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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 🚀

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

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.

[Agentrail @UseAgentrail]

The math on early-stage marketing:

Agency: $8k/mo, 2-week turnaround, junior on your account.
Marketer hire: $120k/yr + ramp.
Freelancer stack: 4 people, 4 Slacks, 0 strategy.
Stella: $600/mo, ships across 6 channels, you approve in 10 min/day.
