Our goal is simple: accelerate innovation. Here's how we're using AI to move faster, build smarter, and help every team member operate at their highest potential.

Walk into our office on any given day, and you'll see engineers pair-programming with AI. Product managers are iterating on specs in real-time with ChatGPT. Our developers are delegating entire tasks to AI agents while they focus on the big picture.
We integrated our systems with best in class AI because we knew it would super charge our next chapter.
AngelList Engineering & Product Philosophy
Don't wait for tools to be "perfect." Experiment early, fail fast, and find what works.
We're not married to any single AI provider. Instead, we use the best tool for each job.
The Workhorse → OpenAI
The Specialist → Anthropic (Claude)
The Eyes → Gemini
Crowd Favorite → Cursor
Our most popular AI Integrated Development Environment. It's like having a senior developer sitting next to you, except they never get tired and they've read every Stack Overflow answer.
Task Delegator → Devin
Working with Devin helps get things done faster than ever. Our developers literally delegate work to Devin through Slack:
Devin maintains living wikis for our repos and handles the smaller tasks so our engineers can focus on architecture and innovation.
Here's something most companies miss: AI tools are only as good as the context you give them. We maintain .cursorrules and .windsurfrules in every repo.
Think of these as constitutional documents for AI—they understand our coding standards, architectural decisions, and the "why" behind our choices.
Example snippet from our rules:
The result? AI suggestions that actually fit our codebase instead of generic Stack Overflow answers.
Quality Control That Actually Works
With Langsmith, every LLM call gets traced. No more "why did the AI do that?" We can see exactly what happened, debug prompts, and improve our workflows.
Patronus is our hallucination detector that catches AI mistakes before they become problems. It's like having a fact-checker that never sleeps.
Meeting Intelligence
Granola ensures that we never lose a great idea because of poor note taking. Granola is our always-on scribe that captures meeting notes, makes them searchable, and lets us query them later. "What did we decide about the API redesign three weeks ago?" Granola knows the answer every time.
#ai Slack Channel
This isn't just another Slack channel—it's our innovation lab. Team members share discoveries, debate new tools, and collectively figure out what's worth our time. This channel open to the entire organization—you’ll even see our Head of People in the chat testing out new tools to optimize employee onboarding, payroll, and more.
Weekly AI All Hands
Every week, we get together to share what's working, what's not working, and what's on the horizon. It's part show-and-tell, part strategy session, part "did you see this crazy new tool?" A recent example that resulted in significantly better outputs for document parsing, which feeds into our automated financial workflows:
A typical developer's day:
The result: Our engineers spend more time solving interesting problems and less time on repetitive tasks.
We're not using AI to replace human creativity, we're using AI to amplify it. Every tool in our stack serves one purpose: helping our team move faster without sacrificing quality to build tools that get more capital into funds, which drives more capital into startups.
The future isn't about humans versus AI. It's about humans with AI building things that neither could create alone.
We're always experimenting with new tools and sharing what we learn. The AI revolution isn't happening to us—we're actively building it.

We have established contractual agreements with vendors to ensure that our data is not used to train any third-party models. AngelList only works with SOC-2 compliant vendors.
