Internal Announcements,
Done Right

Stop losing important decisions in Slack scrollback. Harkn is an internal announcements system designed for teams who care about why decisions were made — not just that they were made.

Announcements are the institutional memory of your team — not just another message.

Your beautiful announcement

The problem: important changes happen everywhere

Teams announce critical changes across Slack, email, docs, and wikis. The result is fragmented context, lost rationale, and repeated debates.

Symptoms you’re missing Harkn

Important announcements disappear into Slack scrollback
Emails don't go to all the right people
Docs are written but no one ever finds out about them
Team members can't reconstruct "why we do it this way"

Slack

✅ Great for fast coordination.

❌ Terrible for durable decisions.

Email

✅ Good as a delivery mechanism.

❌ But who should receive the email?

❌ Information is siloed. Context is lost and announcements are hard to re-discover.

Docs

✅ Great for storing specifications, policies, and reference material.

❌ A black hole for shared reflections (e.g. lessons learned)

❌ Terrible for broadcasting information to the right people.

Wikis

✅ Useful for tech-only teams and ADRs.

❌ Not an org-wide record.

❌ No way to share context across teams.

Harkn creates the perfect medium for your team to create and share announcements — long-form writing, with topic subscriptions, and built-in distribution.

Who Harkn is for

If your team ever says, “Why do we do it this way?” — Harkn is for you.

Great fit for

Companies that have information silos
Remote/distributed teams that need shared moments
Startups growing past informal communication
Teams drowning in repetitive meetings

Decisions

Teams can revisit past decisions and understand why.

Scaling

Move from tribal knowledge to durable record.

Remote teams

Async clarity beats repeated Zoom meetings to talk about the same thing.

Transparency

Make information discoverable by all, not just the select few you emailed at the time.

What Harkn is not

Not a chat app
Not a newsletter platform
Not another docs tool

Harkn is a shared space for decisions, outcomes, and lessons — written once, shared with the right people, visible by all, and useful long after the moment passes.

Build a memory, not just a message.

Stop storing information in a documentation black hole and announcing into the Slack void. Give your team a durable record of what changed — and why.
