Kind of tentatively in the land of who's here today. So if you are if your main responsibility is in a GTM or growth or marketing related role or sales related role, raise your hand. AI mean, you lead killed 3 of them. Just killed 3 afterwards. Okay. So for those of you building internal tools, what are you building? Can it be someone share, maybe? Sure.

Tech stack

DSPY

DSPy (Declarative Self-improving Python) is the Stanford NLP framework that compiles declarative Python code into self-improving, optimized language model pipelines: program LMs, don't prompt them.

DSPy radically shifts LLM development from brittle prompt engineering to compositional Python code (Declarative Self-improving Python). The framework, developed by Stanford NLP, uses a compiler to automatically optimize your AI system: it synthesizes effective prompts, generates few-shot examples, or fine-tunes model weights based on a specified metric (e.g., quality or cost). This systematic approach uses three core abstractions: Signatures (defining input/output), Modules (reusable components like Chain of Thought), and Optimizers (Teleprompters). Since its late 2023 release, DSPy has seen significant adoption, boasting over 28,000 GitHub stars; it is the definitive solution for building robust, modular AI systems, from simple classifiers to complex RAG pipelines.

YALC

A local package manager that bypasses npm link headaches by using a local repository to sync dependencies.

YALC solves the persistent reliability issues of symlinked dependencies by acting as a local repository (located at ~/.yalc) for your packages. It mimics the behavior of a real registry: you publish a package to the local store and add it to your project using a simple 'yalc add' command. This workflow ensures that your node_modules remain consistent, prevents resolution errors common in monorepos, and allows for instant updates across multiple local projects without the fragility of 'npm link' or 'yarn link'.

CLI

The Command Line Interface (CLI): Your direct, text-based terminal for executing commands and automating system operations with maximum efficiency.

CLI is the essential interface for system administration and development: It bypasses the overhead of a Graphical User Interface (GUI) for faster, scriptable workflows. Shells like Bash, Zsh, and PowerShell interpret typed commands (e.g., `ls -l`, `git commit -m`) to manage files, execute programs, and control hardware. The core advantage is automation: Complex, multi-step tasks can be chained and executed instantly via scripts, delivering significant time savings for repetitive operations (often 10x faster than manual GUI clicks).

Clay

Clay is an AI-powered data enrichment and sales prospecting platform built like a spreadsheet to automate personalized outbound campaigns.

Clay acts as a centralized GTM data engine (combining 50-plus data providers like Apollo, LinkedIn, and GitHub into a single interface) to eliminate manual lead research. Teams use its spreadsheet-style UI to scrape websites, verify emails, and leverage built-in AI agents to write highly personalized cold outreach at scale. By replacing fragmented data tools with automated, multi-source enrichment pipelines, companies like Anthropic and Intercom consistently scale their pipeline generation without expanding headcount.

LinkedIn

LinkedIn is the world's premier professional network: It connects over 1 billion members across 200+ countries, driving career development and recruitment for global businesses.

This platform, launched in 2003 and owned by Microsoft (since 2016), is the definitive hub for professional identity and opportunity. Users build digital CVs, network with peers, and follow 67 million company pages: It is a critical talent pipeline where, according to official statistics, six people are hired every minute. LinkedIn’s core function is facilitating job search (65 million weekly searches) and B2B connections, making it the essential digital resource for the global workforce.

CLI tool

A text-based interface that executes precise system actions directly from the terminal.

Command-line interface (CLI) tools bypass heavy graphical overhead to give developers direct, scriptable control over their software stacks. By exposing core functionality through structured terminal commands (like git commit or stripe listen), these tools allow you to automate complex workflows, chain operations together via pipes, and manage remote infrastructure with minimal bandwidth. They turn repetitive manual tasks into predictable, version-controlled scripts that run identically on a local laptop or a headless CI/CD runner.

Claude Code

Anthropic's agentic coding tool: Unleash Claude's raw power directly in your terminal or IDE to turn complex, hours-long workflows into a single command.

Claude Code is Anthropic’s powerful agentic coding assistant, designed for high-velocity development. It operates natively within your terminal, IDE (VS Code, JetBrains), or via a web interface, allowing you to delegate complex tasks like feature building, bug fixing, and codebase navigation. The agent plans, edits files, executes commands, and creates commits, maintaining awareness of your entire project structure. Internally, Anthropic engineers using Claude Code reported a 67% increase in productivity, demonstrating its capacity to deliver significant gains for Pro and Max plan users.

Codex

Codex is OpenAI's autonomous AI software engineering agent: it executes full development tasks in a sandboxed cloud environment.

Codex is the advanced, cloud-based software engineering agent from OpenAI, built on a specialized model like `codex-1` (a fine-tuned version of `o3`). It operates on an asynchronous delegation model, allowing developers to assign complete tasks—not just receive suggestions—via the ChatGPT interface. The agent works independently in a secure, isolated cloud container provisioned with the user's GitHub repository and environment. It reads code, writes new features, fixes bugs, runs tests, and drafts Pull Requests (PRs) for review, significantly accelerating the development lifecycle. Access is provided through ChatGPT Plus, Pro, and Enterprise plans.

Bun

Bun is the fast, all-in-one JavaScript runtime and toolkit: it replaces Node.js, npm, and multiple development tools with a single, cohesive executable.

Bun delivers a high-performance JavaScript runtime, built from scratch in Zig and powered by Apple's JavaScriptCore engine (not V8). It functions as a drop-in replacement for Node.js, but unifies the entire development workflow: the runtime, package manager (e.g., `bun install`), bundler (`bun build`), and test runner (`bun test`) are all integrated. This architecture dramatically reduces startup times and memory usage, offering significant speed gains, especially in tasks like package installation (up to 30x faster than npm) and server-side rendering.

Supabase

The open-source PostgreSQL development platform: a Firebase alternative for rapid backend deployment.

Supabase is the Postgres development platform, providing a complete, open-source backend-as-a-service solution. It packages enterprise-grade tools like a full PostgreSQL database, a RESTful API (via PostgREST), and a GraphQL API (via pg_graphql) that are auto-generated from your schema. The platform includes a comprehensive suite of services: Auth (for user sign-ups and SSO), Storage (for files with S3 integration), Realtime (for database change subscriptions), and Edge Functions (for serverless logic). The core value proposition is clear: build fast with a powerful, scalable SQL database that offers 100% portability and robust security features like Row Level Security (RLS).
