The best Software Platforms newsletters

This newsletter from 2057 Holdings describes how the firm applies one shared operating system across its portfolio of companies, with examples from a smart-home build on Home Assistant, a Cloudflare Worker that puts a unified checkout in front of separate vendor platforms, and AI tooling that enforces each brand's voice. Readers get concrete accounts of the technical setups and the reasoning behind them, though the content is mostly about the firm's own work.

Product-update newsletter from Portal One, an AI agent platform, explaining its agentic loop, built-in sandboxed tools, and E2B-based sandbox environment. Readers learn how agents chain tool calls, which tools need approval, and how sandboxes are isolated and paused.
