The session features six startup founders who have quickly found product-market fit using Claude across industries like agentic coding, design, and music generation.
Many startups mentioned have reached millions of users within 12 months.
Attendees are encouraged to stay until the end for a special opportunity to access Claude 4.
Tempo Labs: Collaboration for Designers and PMs 00:56
Tempo is building an IDE called Cursor designed for Product Managers (PMs) and designers, resembling Figma more than VS Code.
The tool allows PMs and designers to collaborate with Claude, generating the first drafts or even complete pull requests (PRs), enabling non-engineers to directly contribute to code.
Tempo's interface divides work into three tabs: PRD (Product Requirements Document), design, and code.
Demonstration shows real-time collaborative editing, visual rearrangement (like Figma), and instant cloud-based code execution via Docker containers.
Designers now open 10-15% of front-end PRs directly, handling pixel-perfect changes without engineers, and contribute to about 60% of the code in many PRs.
Tempo is about to launch support for Claude 4, further inviting collaboration on code across non-traditional roles.
Zencoders: Automating Routine Work and Scaling Agents 06:20
Only a small fraction (2-5%) of ideas in large software companies are executed due to extensive routine work.
Belief that up to 90% of routine software tasks can be automated to accelerate innovation.
Introduction of AI coding assistants like Claude 3.5 enabled new use cases and significant usage growth (10x–100x increases).
Technical leaps include model support for tools, large context windows, and improved software engineering abilities.
Verification, enabled by computer use, is identified as the next crucial unlock for scaling autonomous AI coding.
Zencoders launched Zen agents: custom agents for entire software development lifecycle (SDLC) tasks, from PRDs to code, verification, and reviews.
Agents can be shared across organizations, with open contribution via a GitHub repo to enhance organizational creativity.
Gamma: Transforming Deck Generation with AI and Web Search 11:02
Gamma’s mission is to help users easily create presentations, documents, websites, and other formats using AI.
Significant metric improvements occurred when upgrading from Sonnet 3.5 to Sonnet 3.7, including an 8% increase in user satisfaction for deck generation.
The major boost came from web search integration, allowing the model to use real-time web data natively.
Demo shows accurate conference decks generated with web search compared to factually incorrect ones without it.
Gamma allows users to generate full documents or sites from single-sentence prompts, with the output reflecting up-to-date, correct information.
Gamma is hiring across engineering, product, and design roles.
Bito is building a leading AI-powered code review platform that integrates with GitHub, GitLab, and Bitbucket, supporting over 50 languages.
The surge in code generation (predicted 10x growth) necessitates scalable, high-quality code review.
Bito's focus is human-like, high-signal review—producing actionable, critical suggestions while minimizing noise.
Live demo shows Bito summarizing PRs, flagging key suggestions (e.g., missing resources, thread safety, and class cast exceptions), and offering one-click code fixes.
In-depth example: Bito traces a class cast exception not readily detectable by humans, demonstrating deep reasoning capabilities powered by Sonnet.
Bito's code review agent can be used directly within IDEs to review local changes.
Impact metrics: PRs close 10x faster (from 50 hours to 5 hours) in companies using Bito, with 80%+ of feedback automated by AI and delivered in minutes.
Refusion is a generative music startup building frontier music models and user experiences for music creation and exploration.
The company’s core model (a diffusion transformer) is trained for quality, diversity, speed, and control.
Claude powers Refusion’s Ghost Writer agent for crafting and refining song lyrics, focusing on diversity, humor, taste, and fit with music genres.
Ghost Writer has been used tens of millions of times.
Demo highlights include fast lyric writing, genre-aware output, and deep editing workflows: remixing, section extension, vocal swapping, and audio-based prompts.
Users can prompt for genre, mood, or even specific intro formats (e.g., spoken word) to refine music outputs.
The product offers a creative, iterative process for artists, with Claude outperforming other models in lyric quality.
Create is an AI agent-based platform allowing users to build full-fledged web and mobile apps using natural language prompts, without coding.
Claude is a key model for powering code generation in Create’s agents.
Recent launch of a mobile app builder enables non-technical users to build and deploy iOS apps through simple prompts.
Live demo illustrates the process: a prompt specifies an app (e.g., family memory app), and the agent assembles frontend, backend, database schemas, and integrations autonomously.
Created apps can be published and submitted to the app store in a single click.
Diverse use cases include memory aids, scholarship application tools, basketball coaching apps, and personal finance assistants.
The explosion of new app creators is expanding who can build software, directly enabled by Claude-powered agents.
