New Halcyon 2.0 now listens to Linear and Zendesk

Find the calm
inside the noise.

Halcyon listens to every channel, ticket and dashboard your team runs on, and hands you the three things that actually need you today.

01 The noise

Monday, 9:04 AM.
1,284 unread.

Almost all of it is noise.

Halcyon hears the one that isn't.

Signal · 3 sources agreeNeeds you today

Acme's renewal is quietly at risk.

Support tickets are up 4x, weekly usage dropped 31%, and their champion Dana mentioned "evaluating options" on Tuesday's call.

02 The signal

Meet your quiet command center.

One calm screen that replaces forty tabs. Every morning Halcyon ranks what changed by consequence, not by volume, and explains why it matters.

Listens to the tools your team already lives in

03 The craft

Built to subtract,
not to add another feed.

Listens everywhere, interrupts nowhere.

Connect 40+ tools in two minutes. Halcyon reads quietly in the background and never posts on your behalf without asking.

Live ranking · 9:06

Ranked by consequence, not volume.

A thread with 400 replies can matter less than one quiet ticket. Halcyon weighs revenue, deadlines and who is waiting on whom.

Your 8:00 brief

A brief, not a feed.

Five sentences every morning. Read it with your coffee, then close it.

Quiet hours, enforced.

Protect deep work for the whole team, with rules everyone can see.

Ask in plain words.

Every answer cites the exact message, ticket or call it came from.

SOC 2 Type IIGDPREU data residencyZero training on your data

Private by design.

Your data is encrypted, region-pinned and never used to train models. Ever.

Learns your team's rhythm.

Halcyon notices when signals cluster and delivers them when people can actually act.

We don't need more dashboards. We need fewer, better moments of attention. Halcyon gives your team back the quiet it takes to do its best work.

04 The flow

From install to inner calm in four steps.

No migration, no new habits. Halcyon works on top of what you already use, and gets sharper every week.

01 Connect · 2 minutes

Plug in your stack.

One-click OAuth for Slack, Gmail, Linear, Zendesk and 40 more. No code, no admin tickets.

02 Listen · always on

It reads, so you don't.

Halcyon builds a living map of your accounts, projects and people from every message in the background.

03 Understand · in context

Patterns become signals.

Scattered hints across tools get joined into one story, with a confidence score and every source attached.

04 Act · where you work

One nudge, at the right time.

Signals land in Slack or email with a suggested next step. Approve, snooze or delegate in one tap.

05 The proof

Teams that found the quiet.

"I used to start every Monday with 1,200 unread. Now I start with three sentences and a coffee."

Maya OkaforVP Customer, Northwind

Halcyon flagged a churn risk eleven days before the customer said a word. We saved a six-figure account with one call.

Daniel ReyesHead of CS, Loop

Our engineers stopped living in Slack. Focus blocks went from a wish to a team norm in about two weeks.

Priya NatarajanCTO, Fieldnote

The citations are the killer feature. I can trust a summary when I can click straight into the ticket it came from.

Tomás IlićCOO, Parcel

Setup took less time than our standup. By lunch it had already found two blocked launches nobody had connected.

Hanna BergProduct Lead, Kiln

"It's the first AI tool that made my week smaller, not bigger."

Marcus ChenFounder, Tandem

We replaced four dashboards and a weekly sync. The morning brief does the job better and nobody has to prepare it.

Sofia MarínChief of Staff, Arcwise

Security review passed on the first try. EU residency and zero training were the two things our legal team cared about.

Jonas WeberCISO, Helio

I check Halcyon once in the morning and once before I log off. That's it. Everything else can wait, and it does.

Amara DialloDirector of Ops, Brightline

Ranking by consequence changed how we prioritize. The loud thread is rarely the important one, and now we can see that.

Leo HartmannVP Engineering, Orbitly

Our response time to enterprise escalations dropped from two days to four hours. Same team, less noise.

Elena RossiHead of Support, Quanta

Honestly I was skeptical. Then it told me about a contract renewal I had completely forgotten. Sold.

Sam WhitakerFounder, Meridian Labs

Only the sources and channels you connect, and you can exclude any channel, label or project. Content is processed in your chosen region, encrypted at rest and never used to train models.

Summaries shorten one channel. Halcyon connects signals across tools, ranks them by business consequence and tells you what to do next, with a citation for every claim.

About two minutes for the first sources. Your first morning brief arrives the next day, and ranking gets noticeably sharper after the first week.

Never by default. Halcyon drafts, you approve. Admins can allow specific automations, like routing an escalation to a channel, with a full audit log.

Yes. Most companies start with Customer Success or Engineering leads, then roll out once the morning brief becomes a habit. The 14-day trial has no seat limit.

You can export everything as JSON at any time. When you close your workspace, all indexed content is permanently deleted within 30 days.
