Both put your deals in Gmail. Streak does it by making Gmail the CRM. OppBox does it by making Gmail read the CRM you already have.
Streak is a CRM built inside Gmail. Pipelines live in spreadsheet-like boxes in your mailbox, with mail merge and email tracking layered on. If you're a small team without a CRM · or you actively want your CRM to be Gmail · Streak is a genuinely clever product for that.
OppBox is the inverse: an opportunity inbox. Your CRM stays Salesforce or HubSpot · the system of record your company already runs · and the inbox becomes deal-aware. Every email knows its deal: account, stage, amount, close date and risk signals, read live from the CRM, plus pipeline views like Ghosted and Renewals.
The one-row summary: Streak replaces the CRM. OppBox reads the CRM you already have.

Streak asks your company to move its pipeline into Gmail. OppBox asks it to move nothing.
If your revenue team already runs Salesforce or HubSpot, the pipeline can't live in a browser extension · forecasting, reporting and management all sit on the CRM. The question isn't where the CRM goes. It's whether your inbox can see it.
You don't have a CRM, or you want out of the one you have. You're a small team, your whole working life is Gmail, and pipelines-as-spreadsheets in the mailbox is exactly the right weight. Add mail merge and tracking and Streak covers a lot of ground for a team that size. It's a genuinely well-made product for that.
Your company already runs Salesforce or HubSpot and that isn't changing. You don't want a second pipeline to maintain · you want the one you have to show up on every email. OppBox reads the CRM live, surfaces the deals that have gone quiet or are slipping, and drafts deal-aware replies you review and send. No sync, no double entry, no data leaving the system of record.
Fourteen days of Core, no card. Connect Gmail and your CRM and watch every email arrive wearing its deal.
