On 6 October 2026 Sierra announced Personal Agent Protocol, an open standard it is developing with Meta and industry partners Genesys, Instinct, Rocket, Shopify, Stripe and Walmart, defining how consumers' personal AI agents authenticate and interact with businesses over websites, APIs and company agents. CNBC reported the same day that Sierra co-founder Bret Taylor is leading the initiative, which is open for anyone to implement.

On Sept 16, 2026, Mercury launched Mercury Books, double-entry accounting software built into its banking product for its 300,000+ customers.

The product is free through the end of 2026, then $35 per month, which moves Mercury into accounting software against incumbents like QuickBooks and adds subscription revenue on top of banking.
