We’ve recently released HubSpot integration at resynced.io and the main difference from the built-in integration is that it allows two-way syncing, and syncing custom fields. Feel free to check out the step-by-step guide here: How to synchronize HubSpot with monday.com | resynced.io
It shouldn’t take more than 5 minutes to set everything up, but should you have any questions, feel free to reach out to me anytime.
