Start at the work
We ask why a workflow exists before we draw a screen for it. What survives the question gets built. The rest disappears, permanently.

The sharpest teams in the world run on tools designed for an org chart. We build the replacements — from the work outward, with intelligence carrying the weight.

02 — Thesis
Twenty years of toolswere built for headcount.None were built for the work.
A project tool that argues with you. A chat thread with no memory. A spreadsheet quietly holding the only version of the truth. The gap between them is where good work goes to wait.
Teams absorb that cost as a fact of life — hours every week spent describing work instead of doing it. We think it is a design failure, and design failures can be fixed.
So we build our own software, ship it to a small number of teams, and hold it for the long term. No roadmap theatre. No platform ambitions. One problem, closed properly.

Everbird.ai
Deals don't die from bad work. They go quiet. Everbird keeps every client deal in one link — proposal, contract, e-signature, invoice, payment — and an AI agent watches it, spots the stall, and follows up the right person from your own email address.
Before
One deal, five systems: inbox, drive, two chat apps, an e-sign tool.
The contract is unsigned, the invoice is unpaid, the client has gone silent — and nobody notices for three weeks, because no single place is keeping score.
After
One link — the client thread. Proposal to signature to paid, in one place either side can open.
An AI agent monitors the thread, detects the stall, and drafts the context-aware follow-up. It sends from your address, so the chase never sounds automated.
Who it's for
Studios, consultancies and independents who sell judgment.
Two people or two hundred. If closing and getting paid depends on you remembering to chase, this is built for you.
The client thread · four states
Proposal goes outPROPOSAL
The proposal goes out as a link, not an attachment. Scope lives inside the thread, and stays the one version everyone is reading.Terms settleAGREEMENT
Contract, e-signature and revisions all sit on the same link. The client never hunts for a file, and never has to ask where things stand.Deal closesSIGNED
Signature lands in the thread and releases the invoice on the same line of the same conversation. Payment closes it out.Nothing stallsFOLLOW-UP
Unsigned, unpaid, or silent for too long — the agent catches it and follows up in your voice, from your email, until the deal moves.05 — NextIn the lab, unannounced.

Yours, possibly
We take briefs from the teams living inside the problem. Tell us what breaks.
We design in the open with a small number of teams who live inside their work all day. Tell us how yours actually runs — that is the spec, and it beats anything we could invent.
