Specs, agents, and CI are all getting serious upgrades this week. Replit’s huge raise and new ways to tame AI‑driven codebases offer plenty for builders who care about reliability as much as speed. We start with two opportunities for software engineers looking to join the teams building the next generation of developer tools.

Depot Secures $10M to Rethink CI for the Agent Era
Depot has raised a $10 million Series A from Felicis, Y Combinator, and Pioneer Fund to build Depot CI, a programmable CI engine designed for teams using AI agents heavily. Founder Kyle Galbraith writes in the company’s announcement that:
“The bottleneck has shifted from writing code to integrating it…The CI systems we have today weren’t built for this moment. GitHub Actions, CircleCI, Buildkite – designed for a world where humans write code, batch it up, push it, and wait. A 15-minute pipeline was annoying but survivable.
Depot CI focuses on fast orchestration, composable compute, and an API‑first design.
🚀 Huge congrats to the Depot team, engineers can dig into the Series A and product details.
Gumloop Lands $50M to Secure and Scale Workplace AI Agents
Gumloop has closed a $50 million Series B led by Benchmark, with Nexus VP, First Round Capital, Y Combinator, Box Group, The Cannon Project, and Shopify Ventures participating. The company provides a platform for building AI agents and automations used by teams at Shopify, Ramp, Gusto, Samsara, Instacart, and Opendoor. The product now spans Gumloop Agents, the core collaboration platform, and Gumstack, a security layer that tracks and audits AI tool usage across vendors like Claude Code, ChatGPT, and Cursor, giving security teams real observability and control.
🎉 Congratulations to the Gumloop team, you can read the full Series B breakdown.
🚀 New DevTools Launched
ZeroSettle Keeps More Mobile Revenue in Developers’ Hands
Former Apple engineers have launched ZeroSettle (YC W26), a drop‑in direct billing SDK that helps mobile teams avoid App Store and Google Play fees after the Epic v Apple ruling. The SDK plugs into Swift, Kotlin, Flutter, and React Native apps in around 15 minutes, bringing native‑style checkout flows, “switch and save” subscription campaigns, smart cancellation flows, and options to use ZeroSettle’s own billing engine or a connected Stripe account. It targets developers who want better margins without rebuilding billing from scratch.
💸 Congrats to Gabe Roeloffs and Ryan Elliott, interested mobile devs can give ZeroSettle a go.
Greptile Ships Agent v4 for Sharper AI Code Review
Greptile has released Agent v4, an upgraded AI code review agent that the team has A/B tested across hundreds of thousands of pull requests. Compared to v3, addressed comments per PR are up 74 percent, the share of comments developers act on has risen from 30 to 43 percent, and “nice catch”‑style replies and upvotes have climbed significantly. Greptile is also moving to a base plus usage model at $30 per developer per month for 50 reviews, then $1 per extra review.
✅ Congratulations to Daksh Gupta and the Greptile crew, you can explore the v4 release and pricing update.
OpenSpec Launches an Open Source Spec Framework for Coding Agents
OpenSpec (YC W26) has launched an open source spec framework that captures what teams are building, why, and how before any code is generated. This launch introduces a spec layer to the codebase via an openspec/ folder, containing a spec library for system capabilities and a changes system for tracking proposals and design tasks. Everything is markdown, checked into Git, and integrated with more than 20 AI tools so agents can read and update specs directly. OpenSpec has already reached over 27k GitHub stars in under six months.
📚 Congrats to founder Tabish Bidiwale, teams can try OpenSpec in their next feature cycle.
Syntropy Rolls Out Agentic Coding for Long‑Horizon Work
Syntropy (YC W26) is bringing an agentic coding app to market that targets complex, long‑horizon engineering tasks rather than quick edits. Teams co‑write a spec with the agent, then Syntropy runs an end‑to‑end pipeline in the background, from PRD generation and task decomposition to parallel execution in isolated worktrees, testing, and merging into a production‑ready PR. Updates arrive in Slack, and the system supports custom MCP integrations for real‑world enterprise stacks.
🚀 Congratulations to founders Saahil Sundaresan and Andrew Kuik, engineering teams can get started with Syntropy today.
