Introducing Apple Messages for Business on @onkeiki 🍏
You can now connect your agent to Apple Messages for Business, so customers can text you from Apple Maps, Safari or your site and get answers under your verified name and logo.
Early access starts today 👇
Massive congrats to Letter for their public launch! Excited to be supporting their new Letterpress-1 beta with @maritime_sh
Impeccable product and team :)
Today, the @lettercompany is releasing the beta of Letterpress-1, the world’s first coding agent, harness, and IDE purpose-built for growth engineering.
tl;dr: check out the 🧵 to see the product in action.
Growth is re-emerging as an engineering problem, but today’s coding tools weren’t designed for it. Your website isn’t isolated like your app: it reacts to the outside world (e.g. agent behavior, Google rankings, observed human interactions, and competitor activity).
Leading coding agents were built to scale complex codebases, not to autonomously build for outside signals. Letterpress-1 is.
Letterpress-1 is designed to tackle growth problems of every size. It’s also proactive: it suggests the nth next thing to build for growth. It'll issue pull requests for de-anonymization, experimental landing pages, warmed emails, blog automations, agent telemetry, etc.
The Letterpress IDE is also built into your site. Press ⌘+L, authenticate, and edit text directly on your website. Letterpress-1 automatically opens a pull request with the change.
Letterpress-1 ships with readily available infrastructure to stage futuristic growth strategies that win over agents. These include:
=> Proofs: autonomous evidence chains that verify customer success data for agent visitors
=> Simulations: staged mirror applications where agents can safely try solutions before buying
=> Benches: self-hosted, reproducible benchmarks with open-source, independent governance
=> Phantoms: autonomous websites to sandbox growth strategies
Build, automate, and refine your growth process with the Letterpress family of tools. We're proud to count some of the world's most forward-thinking startups as our customers.
Sign up today at letter.dev.
I’ll share a few examples of Letterpress-1 in action in the thread below.

Latest Maritime changelog:
- Ephemeral sandboxes from $0.022 an hour
- Swarms: one job across 1,000 sandboxes
- Windows desktops through MCP
we’re teaming up with @supermemory @onkeiki @pumpgtm to help you go viral!
the two things that’ll kill you as a b2c agent startup is bad infra and terrible distribution, and this is the stack that will let you build a truly useful, monetizable agent like instinct
go join the races at competition.maritime.sh
Ary Shrivastava retweeted
I don’t want muse to rule the world.
The next generation of agent companies is being started right now, by people shipping agents that real users text every day.
If that’s you, build it now. Keiki and Maritime cover the tools, hosting and LLM credits. Get to 1,000 users and win $20k in credits plus a trip to SF.

we’re teaming up with @onkeiki to give you the opportunity to build the NEXT INSTINCT
we’re living in a gold rush, especially when it comes to personal agents. but the moat is no longer technical ability, it’s distribution and execution
if you get 1000 real people using your agent, we’ll give you $20k in maritime llm credits and will fly you out to sf
go apply at competition.maritime.sh
Ary Shrivastava retweeted
AI personal assistants are the next gold rush.
And we want OUR users to build the next unicorns.
So @maritime_sh is partnering with @onkeiki to give you everything you need to build and scale the next Instinct.
The first teams to reach 1,000 users get $20,000 in LLM credits and a 3-day trip to SF.
Go build: competition.maritime.sh

I sat down last week with @mariagorskikh from @maritime_sh (YC F26) to discuss the future of sandboxes and agent infrastructure.
This is my second time doing YC, and one of my goals this batch was to not just highlight ourselves, but some of the other amazing companies in the batch.
This conversation is the first of many to come. Looking forward to what @mariagorskikh and @AryShriv build.
Day 6 of 6 of #SFTechWeek, and it sure flew by.
We started the morning building AI teams at our hands-on workshop with Turnstone (W26) and UpScaleX, then wrapped the week at @maritime_sh (YC F26) launch party at Corgi Cafe with agents, corgis, cocktails and a line out the door.
We enjoyed every moment of the chaos. See you next year, same time, same place 🧡
launch party so hype that the police were called for people blocking the street @maritime_sh
we've officially launched Maritime on YC!
when we started Maritime in march, giving every agent its own VM was considered wasteful and stupid
then grokbot, muse, and instinct came out.
ai agents should be fully autonomous, and we made this a possibility through our platform
go deploy your agents on @maritime_sh, go get those users

Introducing Maritime (YC F26): the cloud platform for running billions of AI agents
We give startups the infrastructure to deploy, manage, and scale their agents, each with its own computer
Hosting starts at $1/agent/month
i spent weeks figuring out windows for agents so you don’t have to
30fps windows vms
<1s cold starts
unlimited usage
for literally a dollar a month
you can give your agents access to legacy software, internal enterprise tools, excel/office, and so much more
soon @maritime_sh
Instinct just got valued at $10 billion, and everybody in sf is building their own
i wrote up a guide on how to not burn money doing it
i demo'd a looksmaxxing agent to YC that i one-shotted with claude and @maritime_sh the night before
our partner got cooked, try it out at +1 (203) 945-9310
