Risely AI logo

Risely AI

AI agents that automate administrative work across college campuses.

Risely’s AI agents will form the new operating system for universities, improving retention, staff productivity, and efficiency. Our platform integrates directly into existing university systems (SIS, LMS, CRM), learns each institution’s unique workflows, and deploys specialized AI agents. This dramatically reduces the $735 billion universities spend annually on administrative labor, expands staff capacity without increasing headcount, and improves the student experience. This hasn't been done before because university workflows require nuanced, autonomous judgment, exactly what agentic AI was designed to solve. Our team uniquely combines deep expertise in higher education, enterprise-scale AI, and regulated enterprise sales. Sadia previously built Salesforce’s Education Cloud from scratch, creating the core Student Information System widely used across higher education. She deeply understands university operations and maintains trusted relationships with hundreds of higher-ed CIOs and Provosts. Danial was one of DoorDash’s earliest engineers, where he architected and scaled complex systems from zero to billions of transactions, including their search, recommendation, and Voice AI platforms. He knows how to build robust AI solutions that reliably perform at enterprise scale. Shahryar was a GM at Airwallex, where he built the entire Americas business from 0 to 1 and drove 11x revenue growth. He’s also a master closer, single-handedly securing over $17M in enterprise deals at NerdWallet. He’s a relentless startup executor with deep expertise launching and scaling go-to-market machines in highly regulated industries. We launched six weeks ago and are already at $8k MRR, growing 55% week-over-week -- one of the fastest ramps ever in higher ed. Universities urgently need solutions that expand labor capacity and efficiency, especially as they face unprecedented budget pressure and staffing shortages. With unmatched buyer access, deep technical expertise, and rapid early traction, we are perfectly positioned to own this enormous market.

Rivet logo

Rivet

Rivet helps product designers change software without coding.

Rivet is a visual tool that sits above a codebase. It's a bridge that lets product designers own any UI change to the software they work on. Designers use Rivet today to shortcut painful design handoffs and just make any visual change themselves. This saves time for designers and engineers and makes it radically easier to build software with great design and taste. This becomes the next design tool because it lets designers break out of static tools and prototype like frontend engineers. Use real components from your existing codebase to design remarkably complex interactions, and then ship it yourself.

Riveter AI logo

Riveter AI

Thousands of AI search agents running in parallel

Riveter is bringing the power of Perplexity to the scale of the spreadsheet. Their AI agents, custom scrapers, and integrations pack the power of browser use and automation for search, at a cost that allows for scale. Most teams still spend hours (or hire UpWorkers/contractors) to manually copy product specs, check competitor pricing, pull custom KYB/KYC data to assess customer risk, or scrape filings. Perplexity and ChatGPT are great for single questions, but they can’t handle large amounts of data at once. And they’re working with a single agent and context window instead of one in every cell. And Riveter’s web browsing can go further—even reading PDFs and images that may contain answers. With Riveter, anyone can automate complex, auditable web research… without coding. Our founding team brings deep product and engineering expertise from to YC-backed companies Gusto, Retool, and Middesk.

Riviera logo

Riviera

AI Employees for Hotels

Riviera builds AI Employees for Hotels. Our first agent is a hotel phone receptionist that lets hotels spend less time answering phone calls and more time helping customers. Our system handles front-desk inquiries, in-room dining orders, and reservations. It answers every question instantly and in any language, 24/7. We are solving a problem that older phone systems and IVRs can't: customers hate not being able to talk to someone immediately, but most travel businesses can’t dedicate additional staff to manage phone lines. Voice AI has always seemed out of reach because the technology infrastructure in the travel industry is often fragmented, with reservation systems, loyalty programs, and in-house operations software that weren’t designed with voice AI in mind. Riviera addresses this by integrating seamlessly with existing software providers and using human-sounding voice models that are highly trained on data specific to each business type and department. Hotels spend hundreds of billions annually on staffing and risk losing potential revenue when phone lines are overwhelmed or callers hang up. By enabling them to handle unlimited calls, day or night, Riviera unlocks additional revenue and eases labor challenges.

Roark logo

Roark

Test, monitor, and improve your voice agents

Roark helps teams test, monitor, and improve their voice agents. Voice AI is exploding, but reliability is still the #1 challenge. Teams spend hours manually testing agents and still miss failures. In the last 6 months, Roark has processed over 10M minutes of calls, powering monitoring and simulation for teams across the Voice AI ecosystem (including YC companies). We close that gap by combining: 📊 Monitoring & Evaluation - 40+ built-in metrics (latency, instruction-follow, sentiment, etc.), custom dashboards, alerts, and the ability to define your own. Up to 15 speakers with automatic speaker identification. 🎭 Simulations & Personas - end-to-end phone/WebSocket simulations for inbound and outbound agents, with configurable personas (accents, languages, speech & behavior profiles). Define tests as conversations with a graph-based approach, so you can easily branch into edge cases and variants. 🔁 Full lifecycle loop - failed calls automatically become repeatable tests, so every failure makes your agent stronger. Roark is the missing QA layer for Voice AI - helping teams ship agents they can trust.

RoboTire

Robotire is automating vehicle maintenance for today and future…

In a fleet-centric world where everything is delivered to your doorstep, cost-per-mile and uptime are all that matter. Vehicles will be driving more miles and the decreased complexity of electric motors will fundamentally change the automotive service industry. ROBOTIRE will bring manufacturing-level automation to vehicle servicing. Tires are the perfect vertical to tackle first because they are future-proof (tires are going nowhere) and scale from luxury personal automobiles to freight-centric big-rigs. The current tire changing industry is entrenched with an aging workforce but maintains strong margins. We will build and deploy a robotic tire changing container that can change tires in 10 minutes. Our fully-integrated ROBOTIRE containers can be placed inside existing shops, Walmart parking lots or in the middle of a fleet service area hundreds of miles away from a major city. In the medium term, we will expand to brakes, oil, batteries, etc. becoming an uptime assembly line that keeps fleets on the road 24/7 at a fraction of the maintenance cost per mile we see today. In a fleet-centric world, cost-per-mile and uptime are all that matter. ROBOTIRE tackles both.

Rocketable logo

Rocketable

The AI Maximalist Software Holding Company

Rocketable is building a large portfolio of wildly profitable software businesses by acquiring existing products and replacing human teams with AI agents. Today’s foundation models already possess enough intelligence to automate most of the tasks required to run a profitable software business. In the functions where agents aren’t yet intelligent enough to replace humans, they will be soon. When every human function required to operate a software product has an AI agent equivalent, the next step will be within reach: operating an entire company with a team of AI agents instead of humans. But superintelligent agents within each function won’t be enough. To operate a software company with 0 human employees, the agents will need to be directed towards common goals, integrated to collaborate across functions, tuned with feedback loops connected to product metrics, and trained to make resource allocation decisions. We are creating the tools needed to replace the entire org chart of a software company with a team of AI agents. We are developing these tools by owning the products that we automate, because we know from 10+ years of experience building automated systems with AI/ML that integration is the key to unlocking superhuman performance.
