Over the past 100 (yes, we can’t believe it!) issues of our newsletter, the developer tools sector has undergone a remarkable transformation. Artificial intelligence (AI) has moved from novelty to necessity, infusing virtually every corner of DevTools. In tandem, we’ve seen record levels of investment, a surge of new startups and product launches, a wave of industry consolidation, and significant shifts in hiring trends for devtool roles.
Speaking of roles – what does the hiring market look like in the world of devtools? Despite some high-profile tech-sector layoffs in late 2022 and 2023, devtool-focused companies have largely kept hiring, especially for roles in cloud, AI, and platform engineering. Industry data shows that even companies which downsized last year are now hiring 20% more AI-related roles to refocus on new tech.
From where we stand at issue #100, it’s an exciting time to be building a career in developer tools – and our team have some really great opportunities to get you started or get you to the next stage in your career. Their details are at the end of this newsletter and they look forward to hearing from you.
For now, we are here with the latest funding wins, launches, events and industry news from the developer tools sector.
🏆 Funding Wins
$25M for Composio to Supercharge Smarter Agents
Composio has raised a $25 million Series A to help developers build smarter, faster AI agents. Led by Lightspeed, the round included SV Angel, Dharmesh Shah, Guillermo Rauch, and more.
Founded by Soham Ganatra (Hiring) and Karan Vaidya, Composio streamlines one of the most painful steps in agent development: authentication workflows. Their platform lets agents connect to over 3,000 tools while sharing reinforcement-learned skills across deployments. That’s made it a go-to for startups and enterprises like Glean. The team reports 100K+ developers and 10M+ daily requests already.
“The challenge isn’t making AI smarter in isolation… It’s giving AI the ability to accumulate practical knowledge the way humans do—but at the scale and speed only software can achieve.” (Ganatra)

Droidrun Raises €2.1M to Bring Agents to Your Phone
Berlin’s Droidrun has secured €2.1 million in pre-seed funding to expand its open-source infrastructure for mobile-native AI agents. Merantix Capital led the round, joined by SixtyDegree and angels from Silo AI, Hoxton Ventures, and more.
Co-founders Christian Ninstel, Peter Lächner, Niels Schmidt and Nikolai Dück built Droidrun after finding no agent tools worked reliably on real Android or iOS apps. Their breakthrough? Turning mobile UIs into structured text so LLMs can control apps directly, enabling fast, accurate automation. In just 10 weeks, 900+ devs signed up and Droidrun became the fastest-growing mobile agent repo on GitHub.

IdentifAI Secures €5M to Combat Deepfakes at Scale
Milan-based IdentifAI Labs has raised €5 million to expand across Europe and the US and strengthen its fight against AI-generated disinformation. Founded in 2024 by Marco Ramilli, PhD and Marco Castaldo, the company helps developers and enterprises detect whether images, videos, or voice recordings have been manipulated by AI.
The global AI market is expected to grow 25 times by 2033. With public concern increasing, the need for reliable detection tools is more urgent than ever. IdentifAI’s platform offers a real-time API and web interface, using media forensics and linguistic analysis to flag deepfakes at scale. The round was led by United Ventures.

Weave Closes $4.2M to Give Engineers X-Ray Vision
Weave (YC W25) has raised $4.2 million in seed funding to bring engineering analytics into the AI age. Moonfire and Burst Capital led the round, with Y Combinator also participating.
Founded by Adam Cohen and Andrew Churchill, Weave uses LLMs and proprietary models to analyse every PR, measure actual engineering work, and show what’s being done by humans versus AI. It’s already used by a quarter of new YC companies and teams at every stage.
The platform surfaces hidden patterns in engineering output, helping teams improve review quality, boost productivity, and fine-tune AI usage.

🚀 3, 2, 1… Launches
Palmier Launches Autonomous Engineering Agent for Real Work
Palmier (YC S24), founded by Marcos Rico Peng and Harrison Tin caught our attention last week as they debuted on Product Hunt. Palmier is an autonomous AI assistant that writes code, fixes bugs, reviews PRs, and triages issues, triggered by GitHub events or Slack, and always in full context.
Last month they introduced Custom Agents, giving teams full control over system prompts and tool calls. The result is powerful automation that fits your workflow, not the other way around.

CircleCI Brings Outlier Detection to CI/CD Workflows
CircleCI has launched Platform Team Toolkit, a new solution that helps platform teams manage pipelines at scale without slowing down developers. It centralises config across projects while still allowing individual teams to customise where needed.
By eliminating config sprawl and automating setup with Terraform, the toolkit keeps pipelines consistent, secure, and efficient. It’s built for companies running complex, cross-team workflows who need both speed and control.
🔴 See how Platform Team Toolkit works in this short demo from Derry Bradley
The Browser Company Launches Skill Gallery for Dia
The Browser Company has launched version 0.1 of the Dia Skill Gallery, giving Arc and Dia users an easy way to browse, save, and reuse prompt-based actions. These “skills” let you trigger common workflows in the browser, like finding local events or generating code snippets, then save them for one-click reuse.
While the community had been informally sharing prompts, the official gallery makes discovery simpler, with skills now organised by category and just a click away from your own library.
🔎 Check out Dia and follow along as the team explores what work agents could become.
mcp-use Makes MCP Agents Production-Ready
The team behind mcp-use (YC S25) is making it easier for developers to build and deploy custom AI agents using MCP servers. Their open-source tooling removes the friction of hardcoded configs, vendor lock-in, and poor access control with a one-line integration that handles provisioning, configuration, and security out of the box.
With over 100K SDK downloads and backing from early adopters at NASA, NVIDIA, and SAP, mcp-use is already powering internal agents for search, monitoring, and incident workflows. It’s all about letting devs focus on agent logic, not infrastructure headaches.

stagewise (YC S25) is a frontend coding agent that runs inside your live app, helping you build and iterate faster without switching between tools. Just click on a UI element, leave a comment, and Stagewise updates the local codebase using your browser and app metadata.
Created by Julian Götze and Glenn Toews, stagewise works with any web framework and integrates directly into production-grade projects. No need to move from visual builders to code editors when things get complex. The open-source toolbar has already been downloaded over 130,000 times and earned 4,800 GitHub stars.
🧪 Try it out with code STAGELAUNCH for 25% off the first 3 months.
DeepDocs 📃 Docs That Keep Up With Your Code
DeepDocs is a GitHub-native AI tool that automatically updates your documentation as your code changes. No prompts, no broken formatting, no manual cleanup. It works like CI for your docs, keeping READMEs, SDK guides, onboarding tutorials, and API references in sync with your repo.
Created by Neel Das, PhD, DeepDocs detects doc drift from your commits and opens a clean branch with suggested edits. It understands both code and docs in context, integrates with tools like Docusaurus and MkDocs, and plays nicely with monorepos. As Neel said along with the launch.
“You ship a feature and move on. Then a month later, someone’s onboarding or debugging and runs into stale docs that no longer reflect the code… So I built DeepDocs.”
🛠️ See how it works and try it on your repo at deepdocs.dev and support on Product Hunt.
Blacksmith Unleashes 10x Faster GitHub Actions Cache
Blacksmith has launched a blazing-fast caching service for GitHub Actions, delivering up to 10x speedups over GitHub’s own. No code changes, no forks, no compromise.
After hitting scaling and maintenance limits with their earlier fork-based approach, the team reverse-engineered GitHub’s cache system, routing requests through a colocated, S3-compatible backend via smart VM-level proxying. They tackled challenges across Azure SDK quirks, protocol decoding, and kernel-level networking to make it all invisible and fast.

Frigade Launches In-App Support Agent That Actually Understands Your Product
Frigade has launched Frigade AI, an in-app agent that learns how your product works and helps users stay unblocked with step-by-step, real-time support. It generates tutorials on the fly, highlights features at the right time, and can even act on behalf of the user…all without relying on stale help docs or rigid paths.
co-founder, Eric Brownrout announced on Linkedin last week:
“We announced Frigade AI in March with what felt like an impossible goal: build an AI that could help users navigate a product without having to manually teach it every single workflow first….Frigade AI learns by doing. It uses your product the same way your users do and builds understanding through actual experience rather than scripts or help docs.”
🎯 Watch the intro video, explore Frigade AI and book a demo.
