NewThe collaboration layer for iMessage

Make your texts collaborative.

Text is your most personal, highest-converting channel — and the one you can’t delegate. Message Vault runs your iMessage on a secure hosted Mac and a blazing-fast web app, so you can loop your team or an AI agent into the threads that matter.

Scoped, per-thread access Collaborators never get your accountBuilt for founders, sales & execs

Built for the people who close deals over text

The problem

The channel that converts best is the one you can’t scale.

High-leverage people get pulled onto text by everyone who wants something — intros, sales, deals. And text is the one place they have no leverage back.

01

It’s trapped on one phone

Your most important relationships live in iMessage — but it’s locked to a single device. No one can help you carry it, and nothing scales past your two thumbs.

02

You can’t delegate it

Email lets you cc your team, loop in an assistant, hand off a thread. Text gives you none of that. The busiest people get the most texts and have the least ability to triage them.

03

So deals quietly die

The intro you meant to make, the follow-up you swore you’d send, the buyer waiting on a reply — they slip between read receipts and never come back.

How it works

From locked-down to delegatable in three steps.

Your messages, on a secure hosted Mac and a fast web app — with collaboration built in from day one.

1

Connect once, securely

Your iMessage runs on a dedicated, hosted Mac in a hardened environment. Sign in once — your phone stays yours, and nothing is scraped to a third party.

2

Work in a fast web app

Search, triage, and reply from a keyboard-first inbox built for speed. Every thread, on every device, with the snappiness power users expect.

3

Invite your team or an agent

Grant scoped access to specific threads — for a chief of staff, a sales rep, or an AI agent. They act on your behalf without ever seeing your whole account.

Scoped access

Share a thread. Not your whole life.

  • Thread-level grants

    Pick exactly which conversations a teammate or agent can see and reply to — nothing more.

  • No account-wide access

    Collaborators never touch your Apple ID, your device, or the threads you didn’t share.

  • Revoke anytime

    Access is yours to give and take back instantly, with a full record of who did what.

Use cases

Wherever a dropped text costs you.

Founders

Never fumble a warm intro

An investor texts a founder your way. Forward the thread to your assistant, who schedules and follows up — while you stay in the loop and the relationship stays warm.

Sales

Follow-ups that actually happen

Your reps live in text with prospects. Share deal threads with the team, track who owes a reply, and let no “let me check and get back to you” go cold again.

Chief of staff

Run the principal’s text inbox

Give your EA reply-all access to the threads that matter — logistics, scheduling, intros — with zero visibility into personal or sensitive conversations.

AI agent

An agent that works your threads

Point an AI agent at a set of threads to draft replies, surface what needs you, and handle the routine — permissioned to exactly those conversations and nothing more.

Security & trust

You stay in control. Always.

Delegation only works if it’s safe. Message Vault is built so that sharing a thread never means sharing everything.

Per-thread permissions

Access is granted thread by thread. Collaborators see only what you explicitly share.

No Apple credentials shared

Teammates never get your Apple ID, password, or device. Their access is scoped and revocable.

Full visibility & audit

See who has access to what, watch activity, and revoke anyone in one click.

Isolated & encrypted

Your messages live in a dedicated, isolated environment — encrypted in transit and at rest.

Early access

Stop losing deals in your texts.

Message Vault is rolling out to a first group of founders, sales teams, and execs. Add your email and we’ll reach out with your invite.

FAQ

Questions, answered.

Does Message Vault need my phone or my Apple password forever?
You connect your iMessage once to a dedicated, hosted Mac. Your phone stays in your pocket and keeps working exactly as before. We never hand your Apple credentials to collaborators — their access is scoped to the threads you choose and can be revoked at any time.
What can a collaborator actually see?
Only the specific threads you grant them. A chief of staff with access to three logistics threads cannot see your family group chat, your other conversations, or your account settings. Access is least-privilege by default.
How is this different from just sharing my screen or forwarding texts?
Forwarding loses context and screen-sharing exposes everything. Message Vault gives real, permissioned, two-way access to chosen threads — your teammate or agent can read history and reply in the actual conversation, scoped to exactly what you allow.
Can an AI agent really send messages on my behalf?
Yes — an agent can be granted the same scoped, per-thread access a teammate gets. It can draft, triage, and (with your rules) reply within those threads only. You stay in control of what it can touch.
Is iMessage on a hosted Mac allowed?
Message Vault runs your messages in a dedicated, isolated macOS environment that you connect — built to keep your data private and under your control. We’ll share the full security and architecture details with you during onboarding.
Who is this for?
Founders, executives, salespeople, and investors — anyone whose deals and relationships run through text and who needs to delegate, collaborate, and never drop a thread. If you already pay for premium productivity tools, you’ll feel right at home.
