01 · Ask

Ask like you'd ask a friend

Type the question in Slack. WhoCan matches it against what your teammates have actually helped with — not what they claim on a CV.

You, in Slack:

who can help me debug a gnarly Postgres deadlock? 🙏

WhoCan, two minutes later: an intro to the teammate who fixed exactly this — twice.

02 · Match

The bot does the awkward part

It quietly asks the right people, collects referrals when they're busy, and makes the intro in minutes — inside Slack.

03 · Recognition

Helping finally gets seen

Every accepted request, endorsement and thank-you compounds into an expertise fingerprint you couldn't have written yourself — and a share card that proves it.

Questions

Who can see my profile?

Teammates — people signed in from the same Slack workspace. The only exception is a share link you mint yourself, which shows a minimal public card (name, level, top skill names — never your email, bio or activity).

Where do the skills and endorsements come from?

From real help: when you accept a request or teammates react to your help in Slack, it becomes evidence on your profile. You can add skills yourself too.

Do I need the bot installed?

Yes — this app is the web companion to the WhoCan Slack bot. Add it to your workspace with the button above, say hi, and sign in here.

What does it cost?

WhoCan is in free public beta.
