Streak is a Gmail-native CRM with tracking bundled in. Migrating from Streak means two things: pick a replacement CRM (HubSpot CRM Free, Pipedrive, or another) and pick a tracking layer (Outsolvi). The combined cost of Outsolvi + HubSpot CRM Free is roughly 1/3rd of Streak Pro at $59/user/mo yearly and gives you confidence-scored tracking plus native Outlook + Gmail (Streak is Gmail-only).
The migration is structured as: Day 0 prep with pipeline export and replacement-CRM selection, Day 1 install Outsolvi + set up replacement CRM, Day 7 import pipeline data into the new CRM and configure webhook, Day 14 cutover from Streak to new stack, Day 30 cancel Streak. Total timeline is longer than Mailtrack migration (because CRM transition is involved) and shorter than enterprise Salesforce migrations.
