with the skill

Here's the newsletter, ready to paste into Slack or email. --- **Halvard Labs Monthly Newsletter: October** :megaphone: **Company Announcements** - We opened our Lisbon office on Oct 6, and 40 teammates already work there. - Tomas Reyes joins us as our new VP of Engineering on Nov 2. He was introduced at the Oct 16 all-hands. :dart: **Progress on Priorities** - Enterprise revenue: we're at 72% of our Q4 target as of Oct 20, per CEO Priya Nand's Q4 goal update. - Product: Mobile app 5.0 shipped Oct 15, and it includes offline mode. :pillar: **Leadership Updates** - Priya Nand shared the Q4 company goal update, with enterprise revenue as the headline number (see above). - Tomas Reyes will lead Engineering starting Nov 2. :white_check_mark: **Action Needed** - Benefits open enrollment runs Nov 1 to Nov 14. If you don't make a selection, you keep your current plan.

:jack_o_lantern: **Social Updates** - The Halloween costume contest happens in all offices on Oct 30, with prizes from the social committee. --- **What I left out** - **Series C:** I left it out because you marked it confidential until the Nov 3 announcement. If you want to tease it, I can add a line like "Big news coming Nov 3" instead. - **Finance standup moving from 9:00 to 9:15:** This only affects one team, so it's better shared in that team's channel. **Before you send** - I had no source links, so I didn't add any. Links to the Q4 goal update, the all-hands recording, the 5.0 release notes, and the benefits enrollment page would make this more useful. - This is shorter than the usual 20-25 bullets because I only used what was relevant to the whole company. If you have more material, send it over and I'll expand it.

**🎃 Halloween costume contest: Oct 30** All offices are taking part on Oct 30, and the social committee is providing prizes. Dress up and join in, whether you're in the office or at home. Thanks for all you do, [Name / Internal Communications] --- A note for you, not for the newsletter: I left out the Series C news because it's confidential until the Nov 3 announcement. I also left out the finance standup change since it only affects that team. It would be better shared directly with them.
