Peoplebox.ai is trying to do something most HR tech companies only gesture at: rebuild the entire talent stack from the ground up around AI.

Speedy Labs, a Y Combinator Winter 2023 company, is taking aim at a financial problem that quietly drains billions of dollars from manufacturers and distributors every year: the opaque, spreadsheet-driven world of rebate management.

Alex, a Y Combinator Winter 2024 company, is betting that an AI recruiter can do that first conversation not just faster, but better, and the company’s early momentum suggests a lot of employers agree. The first real filter in most hiring processes is still a phone screen: a harried recruiter, a candidate balancing their calendar, […]
sync., an AI lipsync tool for video content creators and a Y Combinator Winter 2024 company, is drawing industry attention as it scales operations following its accelerator cohort. The company’s mission is to make video as fluid and editable as a word document — letting creators record once, revise at will, and post, without re-recording […]

Founded in 2023 by Anton Koenig and David Grossman, VideoGen lets anyone generate professional, copyright-free videos in seconds using AI — a proposition that has already won […]
Roark, a Y Combinator Winter 2025 company, is betting that the difference between a novelty and a trustworthy product comes down to rigorous, automated testing — and it is building the platform to make that possible. As enterprises race to deploy voice agents for customer support, sales, and operations, a quieter problem has surfaced behind […]
Aravolta, a Y Combinator-backed company, is building the unified software layer that data center operators have long wanted. Data centers have become the beating heart of the AI economy, but the software running them is often surprisingly primitive. Operators juggle a patchwork of tools to track power usage, environmental conditions, and hardware health — tools […]
Probo, part of Y Combinator’s Spring 2025 batch, is launching with a simple promise to early-stage companies: stop losing weeks to compliance. The company positions itself as a fully outsourced compliance team, handling everything from setting requirements to running the audit, so founders can focus on building their business instead of managing SOC 2 and […]
Telemetron, a Y Combinator Fall 2025 company, is building an AI-powered support and operations platform tailored for hardware products — and going after a category that most modern support platforms quietly ignore: the messy, high-stakes world of hardware customer support. The platform serves medical devices, consumer electronics, industrial hardware, robotics, and the rest of the […]
Most customer support software is built around a reactive loop: a user runs into a problem, opens a ticket, waits in a queue, and eventually gets an answer. Signals, a Y Combinator Winter 2026 startup, is flipping that model on its head. The company is building an AI customer engagement platform that engages high-value customers […]
Frizzle, a Y Combinator Summer 2025 company based in San Francisco, has built an AI product aimed squarely at one of the most stubborn time sinks in American education: grading. Teachers routinely spend more than 10 hours per week – roughly a quarter of all their working time – evaluating student work, especially handwritten math […]
Hypercubic, a Fall 2025 Y Combinator-backed startup, is tackling one of the most valuable and least glamorous technology problems in the global economy: the decades-old COBOL codebases running on mainframes that continue to power the core systems of banks, insurers, airlines, telecoms, and retailers. The company is building an AI-native platform to maintain, understand, and […]
Consumer packaged goods brands have long been celebrated for their marketing and product innovation, but their back-office operations remain stuck in the spreadsheet era. Corvera, a Y Combinator–backed startup, is attacking that gap with an AI agent workforce purpose-built for CPG operations – and the early traction suggests the market has been waiting for exactly […]
For two decades, the marketing stack has been organized around a familiar funnel: someone searches Google, lands on a website, and converts through a carefully optimized series of pages. That funnel is starting to break. Increasingly, prospective customers do their research inside ChatGPT, Perplexity, and other AI agents – which then surface a small set […]
Ask any plant manager where the bottlenecks are and the answer rarely involves the factory floor itself. It is the paperwork around it – the RFQs that need processing, the quotes that need chasing, the suppliers that need reminding, and the production schedules that need rewiring every time reality intrudes. Korso, a Y Combinator Spring […]
Outbound sales has become an arms race of volume, and small teams are losing. Cold lists, mass sequences, and blanket personalization tools have driven reply rates to historic lows while inboxes become harder to crack. Gojiberry AI, a Y Combinator Spring 2026 company, is pitching a different approach: an AI outbound sales platform with a […]
Kuli, a Y Combinator Spring 2026 company, is rebuilding the AI influencer marketing stack around a single agent that actually watches social video content the way a seasoned marketer would. Where legacy platforms hand marketing teams yet another searchable database and a CRM, Kuli positions itself as the orchestration layer that takes work off their […]
Modern is taking aim at one of the quiet productivity drains of large organizations: the endless stream of low-complexity, high-volume internal requests that clog up IT help desks, HR mailboxes, and finance approval queues. The Y Combinator Spring 2026 company believes AI agents can resolve more than 80 percent of those requests automatically – and […]
