[Overlap](https://zerogtalent.com/ai-companies/overlap), a San Francisco startup building autonomous multimodal AI agents for video production, is expanding its team across engineering, sales, and marketing. Backed by Y Combinator's Summer 2024 batch and seed investors including Pioneer Fund and Collaborative Fund, the six-person company is hiring for five roles in San Francisco.

Founded in 2023, Overlap automates post-production workflows that typically require teams of human video editors. Its agents ingest long-form footage from cloud storage or YouTube, identify engaging moments, apply edits, generate captions and motion graphics, and distribute content across social platforms while tracking engagement to improve future output.

## From Podcast Discovery to Autonomous Video Editing

Overlap began as a consumer discovery app designed to curate short clips from long-form audio. During an interview on [InProd](https://www.youtube.com/watch?v=Kqwc18WRRII), co-founder and CEO [Jonathan Baer](https://zerogtalent.com/people/jonathan-baer) described how the company evolved: podcasters using the consumer app routinely asked if they could obtain the clips for their own distribution, prompting the founders to build tooling directly for creators and media businesses.

Speaking on [Deepgram's AI Minds podcast](https://www.youtube.com/watch?v=nsqCVPulQyc), co-founder and CTO [Casey Traina](https://zerogtalent.com/people/casey-traina) explained the pivot. When the team began manually emailing generated clips to podcasters, demand surged. Overlap shifted focus to building an autonomous agent that links to a creator's YouTube channel, Dropbox, or Google Drive, continuously monitoring for new uploads. Once an episode drops, the system cuts clips, applies the creator's branding, watermark, music, and subtitles, and drafts copy adapted to the style of individual platforms such as TikTok or LinkedIn.

The system incorporates an iterative learning loop: as posts go live, the agent tracks virality metrics across social platforms and feeds engagement data back into its moment-selection models to improve future clip performance.

## Multimodal Agents and the o1 Architecture

Handling video understanding remains one of machine learning's steepest engineering hurdles. In his AI Minds interview, Traina noted that video remains an unsolved medium in AI because existing large multimodal models still struggle with temporal coherence and granular visual reasoning, such as frame-by-frame context and question answering.

To solve this, Overlap splits the video pipeline across specialized agents. Baer explained on InProd that the backend uses an open-source speech-to-text engine to transcribe audio, which then passes through a coordinated pipeline of large language models. Individual agents handle distinct tasks: pinpointing starting points, establishing endings, verifying necessary context, and evaluating virality potential.

Following an OpenAI hackathon, Overlap rebuilt its clipping pipeline around OpenAI's o1 reasoning model, giving the platform earlier access to advanced reasoning than standard API releases. For video styling and graphics, the engineering team is currently pushing to automate senior-level editing capabilities, such as adaptive color grading and placing animated typography behind subjects.

## The Team Behind Overlap

Overlap was founded by [Jonathan Baer](https://zerogtalent.com/people/jonathan-baer), [Casey Traina](https://zerogtalent.com/people/casey-traina), and COO [Buzz Rubenstein](https://zerogtalent.com/people/buzz-rubenstein).

Baer holds a bachelor's degree in Philosophy, Politics, and Economics from the University of Pennsylvania and an MBA from the Stanford Graduate School of Business. Before business school, he worked in public policy at Meta, where his responsibilities included preparing chief executive Mark Zuckerberg and chief operating officer Sheryl Sandberg for congressional testimony during the Cambridge Analytica hearings.

Traina began coding at age 10, building iOS applications in Swift. He studied computer science at Stanford University before leaving school after his freshman year to build Overlap full-time, influenced by a campus talk from Sam Altman urging prospective founders to build immediately rather than wait.

## Open Engineering and Go-to-Market Roles

The company is currently hiring five on-site roles at its headquarters in San Francisco, working directly alongside the founders.

On the technical side, Overlap is hiring a full-time [Product Engineer](https://zerogtalent.com/ai-jobs/overlap/product-engineer-104393) ($120,000–$180,000 per year) to build and ship core product features across a Next.js frontend and Python backend hosted on Google Cloud. The engineering team is also offering a [Software Engineering Internship](https://zerogtalent.com/ai-jobs/overlap/product-engineering-internship-95425) ($6,000–$9,000 per month) focused on shipping features across the web app, backend, and AI workflows, including creating and improving agents for clipping, editing, posting, analysis, and automation.

To support distribution across entertainment and creator sectors, the startup is hiring an [Account Executive, SMB & Creators](https://zerogtalent.com/ai-jobs/overlap/account-executive-smb-creators-97598) ($100,000–$300,000 per year) to own the sales cycle from prospecting through close, running demos, and closing deals. Supporting go-to-market efforts are a [GTM Internship](https://zerogtalent.com/ai-jobs/overlap/gtm-internship-104530) ($6,000–$9,000 per month) targeting lead generation, account sourcing, and outbound across media companies and creators, and a [Marketing Internship](https://zerogtalent.com/ai-jobs/overlap/marketing-internship-104529) ($6,000–$9,000 per month) to run social accounts, produce events, and develop creative campaigns.
