To do so, we’re building the platform for global logistics—empowering buyers, sellers and their logistics partners with the technology and services they need to grow and innovate.

    Dropbox is building the world’s first smart workspace. Back in 2007, making work better for people meant designing a simpler way to keep files in sync. Today, it means designing products that reduce busywork so you can focus on the work that matters. Most “productivity tools” get in your way. They constantly ping, distract, and disrupt your team’s flow, so you spend your days switching between apps and tracking down feedback. It’s busywork, not the meaningful stuff. We want to change this. We believe there’s a more enlightened way to work. Dropbox helps people be organized, stay focused, and get in sync with their teams.

    Sidekick is an AI-powered SMS assistant for frontline workers in manufacturing, auto dealerships, and retail. The idea came from Justin's father, who owns a manufacturing facility and asked him to build a tool to help with worker onboarding, training, and organizing company knowledge. Workers text questions in any language and get instant answers from their company's documents — no app, no login, works on any phone. They can send photos of equipment for instant identification or voice memos when their hands are dirty or they're wearing gloves. Managers upload documents and record video walkthroughs; Sidekick automatically generates step-by-step tutorials and a searchable knowledge base. When Sidekick can't answer, it escalates to the manager via SMS and learns from the response, getting smarter with every interaction.

  • Trellis
    Trellis
    Y Combinator LogoP2026
    Active • 6 employees • San Francisco, CA, USA
    Short-term rental operators suffer from diseconomies of scale. As listing count grows, operational complexity increases exponentially, managers lose control, reviews drop, and so do rates and homeowner retention. Most are stuck between 10 and 50 listings, using 5 to 10 different software tools, none flexible enough for their needs. There is no unified data layer of their company. They navigate in the dark, reacting to problems rather than delivering hospitality. Trellis unifies everything into one platform, giving AI agents complete context over operations (communications, tasks, workforce, smart homes, bookings, accounting, revenue management) so they can orchestrate work end to end. We believe software is being commoditized. We reached feature parity with competitors in two weeks. If agents can build software that fast, then every SaaS product becomes a software builder. The vendor provides the trellis: the fixed infrastructure. The AI grows the vines: dynamic features, workflows, and interfaces that adapt to each customer. No more adapting to the tool. The tool adapts to you. But the real value is not in what the agent does for one company. It is in what it learns across all of them. Every workflow that works, every SOP that survives contact with guests, every resolution pattern that prevents a bad review feeds back into the network. The agent shares best practices, battle proven SOPs, and guest intelligence across companies. This creates a network of property management brands where the experience is designed by humans and ensured by software. Quality becomes predictable. Scale becomes unlimited. Hospitality is no longer a people problem, it is a software problem. Airbnb built the marketplace. We are building the machine that runs it.

    Kuli is an AI agent for social media and influencer marketing teams at the world's largest consumer brands. Our agent watches every video on socials in the brand's context and helps marketers get work done to launch their campaigns 4x faster. Previous platforms gave marketers databases to search through and a CRM. Kuli actually watches the content. Marketers at team like Supercell, Disney and Havas use it to scout creators, run analysis on trends and competitor strategies, and analyse what makes their campaign perform better. For 10 years, influencer marketing meant more tools, more tabs, more spreadsheets. Kuli replaces all of that with one single agent you orchestrate. One marketer with Kuli does what a $50K/month agency bills for manual tasks.

    Salesgraph equips reps with the most relevant context throughout the deal stage, providing proactive pre-call notes and post-call next steps. Sellers are CEOs of their deals; they need to know who the buyer is, what triggered them to take the first call, what their pain points are, how much value this new tool is bringing, are there any technical blockers, etc. A sale is only good when it doesn't feel like a sale to your customer, but rather the sales rep solved a problem for the customer. This was the problem Ricardo and I solved at Mintlify. We created a business case generator that took in call recordings, background news triggers and job updates, Mintlify's ROI and Pricing calculator, past deals won, and customer case studies --> produced a 3 page document expressing the value Mintlify provided + why the quote presented is justifiable. In doing so we closed more enterprise deals at a higher ACV as our champion was able to build a better purchasing case internally. Our goal is to empower every sales team to close deals at a higher ACV, while making sure reps learn from their mistakes and create a smooth sales experience for their end customer.

    AI chatbots can answer questions, but they can't do your work — they aren't connected to your tools, can't take actions, and stop running when you close the tab. Meanwhile, knowledge workers are still spending most of their day switching between dozens of SaaS apps, manually stitching together workflows that should be automated. Tasklet is the AI agent that actually does the work. It connects to every tool you use — via thousands of built-in integrations, any HTTP API, or MCP servers — and takes real actions on your behalf: pulling reports, updating CRMs, triaging emails, processing data, and more. When it needs a UI, it generates one on the fly. When it needs to crunch numbers or do bulk operations, it writes and runs code in a cloud sandbox. When it needs to interact with a website that doesn't have an API, it uses a real browser. And because it runs in the cloud 24/7, you can set up triggers to have it take ongoing responsibility for workflows — not just do something once, but handle it going forward. The product is deliberately simple: a chat interface where you talk to an extremely capable agent. But underneath that simplicity is a cloud-native agent runtime, best-in-class context engineering, a universal connections layer, and multi-model support that keeps us on the frontier as AI improves. We think legacy SaaS is being unbundled by agents, and Tasklet is the operating system that ties it all together.

    Pulsent continuously watches how your users and interacts with your product and engages them at the right moment to convert, upsell, and retain. As companies scale, founders, account managers and customer success teams can only take care of a small fraction of users. The rest receive generic, annoying and poorly timed communication. Opportunities are missed, customers churn, and revenue is lost. The core problem is that user behavior is fragmented across tools like PostHog, Stripe, Salesforce, etc., making it impossible to understand users in real time. We unify all data into a single view and let AI agents act on top. This only recently became possible with advances in visual AI (dec ‘25), allowing agents to watch sessions and understand behavior at human or better level. Pulsent detects expansion and churn signals, prioritizes high-value accounts, and executes through AI agents across channels like email, LinkedIn, and WhatsApp. It increases conversion and reduces churn without adding headcount. We already have paying customers, process hundreds of millions of events daily, and are seeing strong demand from PLG B2B Clients. Nicolò is an ex-BCG who has scaled two startups to millions in ARR. Arseniy worked for several years at Datadog handling billions of datapoints. We’ve worked together for 3+ years and experienced this problem firsthand in our previous startup.

    Enterprise software implementation is broken, and it has been for decades. Every rollout, whether it's a traditional ERP or a new AI system, requires months of manual integration, configuration, and tuning done by armies of system integrators and forward-deployed engineers. Lab0 builds agentic systems that automate this layer, compressing months-long implementations into weeks.

    Most B2B churn is preventable - most teams just see it too late. By the time a CSM notices, the champion has already quietly disengaged, key features went unadopted, and the renewal conversation is damage control. The dangerous part? The customer might still be logging in, but they've stopped using what actually matters. Userlens catches all of that months earlier. Our AI agents monitor every user at every account the way your best CSM watches your top five strategic accounts: - feature adoption - usage trends - champion engagement - sentiment shifts in Slack and Intercom - open support issues. When a signal hits (churn risk, renewal, expansion opportunity), Userlens doesn't just alert you. It builds the talking points and deck on top of your team's approved templates and playbook. If you have CSMs, Userlens makes every one of them your best. If you don't have one yet, Userlens runs your book like the best CSM money could buy.
