Productivity Startups funded by Y Combinator (YC) 2026

Founded in 2011, Zapier is the #1 workflow automation platform for small and mid-sized businesses. By connecting more than 6,000 of the most popular work apps, Zapier empowers its users to make the most of the tools they already use—and to focus on what matters most.

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.

AI made software engineers 100x more productive. We're bringing that same transformation to knowledge workers with the AI desktop.

Like ChatGPT or Claude, but it runs in the cloud, remembers everything you give it, and comes loaded with skills. Hand it a job tonight and read the answer in the morning. Use it on your own, or with your whole team.

Nobody's built truly proactive AI, because it requires running inference on your entire life. In the cloud, that's insanely expensive and a privacy nightmare. But not on your own chip. Every night, Sentient's on-device LLM wakes your Mac and understands what's new in your life (email, messages, files, Granola transcripts...), entirely locally, and distills it into a knowledge base. You wake up to your work already prepared: the reply you forgot, drafted from your own context; the subscription you never use renewing tomorrow, caught; the report you promised in the group chat, ready to send. Everything is one click from firing through computer use, and nothing fires until you click. Or click your Mac notch anytime and say "finish this for me." Sidekick takes over the thing you were doing with its own cursor while you move on. On-device inference at this scale was supposed to be impossible: devices too slow, and models too dumb. So we built the stack ourselves: a custom LiteRT-LM fork (KV-cache reuse, speculative decoding, custom k-quants) that runs nightly on 8 GB Macs. The user's hardware does ~90% of the compute, and their own ChatGPT or Claude subscription does the rest, so our marginal cost is ~$0, and our servers store nothing. We soft-launched late July with one Reddit post: top of r/macapps, 2,000+ users in 48 hours, $0 marketing. Free and open source for consumers; the same engine on the work stack (Slack, Granola, Linear, Notion) becomes the enterprise business. Sentient OS raised ~$1M in pre-seed, backed by YC, Afore, and the a16z Speedrun scout fund.

Marker is a platform for rebuilding enterprises agent-first, delivered by forward-deployed engineers. It productizes every step from discovery to production, so every agent we ship makes the next one faster.

We're scaling self-improving AI scientist teams to ideate/experiment/discover, generating new knowledge autonomously. Their discoveries reduced ARC-1/2 costs by 10,000× while maintaining state-of-the-art accuracy and yielded material advances on combinatorial ML problems. We believe that AI is bounded not by compute, but ideas. Scaling to millions of sessions of discovery enables leveraging its own discoveries and presents a novel training source capable of ushering a new era of self-reliant foundational models.

OneCLI (YC S26) is an open-source AI teammates platform for teams. Like Grok Bot, but self-hostable, loved by developers. Each employee gets their own sandboxed pro assistant agent, connected to their GitHub, Gmail, Notion, Dropbox, or CRM right from the chat/Slack, while the whole workspace runs under one policy your admins control. Agents never hold real secrets: the credential is injected at the network layer, per request, after the call is authorized. You can't steal what isn't there.

Screenpipe records and learns how people in your company work and turns it into a searchable memory, documents, and AI agents. Model agnostic and data is stored on your device and/or where your team choose, source available.

Savant is the company brain every AI-native enterprise runs on. We plug into the tools you already use, capture the written knowledge / undocumented procedures, and serve them to your employees and agents at decision time.

Glen is the layer that unifies every agent your company runs. Glen pulls in agent sessions from Claude Code, Codex and Cursor, plus Slack messages, GitHub prs, tickets, docs and calls. When a new agent picks up a task, Glen finds relevant prior context and injects it in the agents context window to steer it, producing knowledge work that is significantly higher quality, faster and cheaper. Glen does more. You can query the original agent behind any line of code, or search every session your org has ever run. It distills what your team does into skills and surfaces the right one automatically. Agents work multiplayer, picking up the style and context of whoever else is on the file. Transcripts are unified across Claude Code, Codex and Cursor, so you can hand a session from one to another mid-task. And Glen can also double as a company brain, from Slack, in app, or by just installing Glen on any agent. We’re building toward a future where memory is no longer the missing piece of intelligence. A future where every agent maintains a lossless and continuous thread of institutional experience enabling the era of the compounding organization and fully unsupervised digital labour.

Hyper is a shared brain that plugs into all information flowing inside a company, creates a self-maintaining knowledge graph, and makes your AI employees better and ultimately saves people time. Our in-house memory system scores at or above SOTA on most public benchmarks, and we've built a custom eval suite to measure our precision/recall metrics. In the last 12 days since launch, we've gotten top 5 / top 12 on hacker news & product hunt, onboarded 50+ teams, grown 0 to 1k MRR, and are scoping paid design pilots with co's like Razorpay and Snorkel AI. Our whole lives we've packaged hardcore engineering into beautifully simple products, and that's how we’ll win this platform shift.

Aster is the first autonomous research lab — thousands of AI research agents orchestrated in parallel toward a single goal. We're on a mission to automate open-ended research: research that defines its own problems before it can answer them. The future doesn't wait to be defined by benchmarks. Neither do we.

Pentagon is a workspace for your AI employees to communicate, coordinate, and get work done as a team.

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.

Billions of machines are left untouched by agents and work individually. We connect them to unlock multiplayer cloud coding agents for work like engineering, math and research.

Companies today are growing faster than ever with smaller teams. The best AI-native companies don’t just need more users - they need more of their users becoming power users. Userlens makes it possible for lean teams to drive product adoption proactively, at scale. Userlens is building the AI product adoption expert. Our goal is to help every user at every company get more value from the product they already use. Most teams still rely on onboarding flows, lifecycle emails, support docs, and reactive CSM outreach. Userlens breaks that ceiling. Lumi watches how users actually use your product, spots when they’re ready for the next feature, workflow, or habit, and nudges them at exactly the right moment.

OpenWork is a desktop app that lets people connect to their existing skills, MCPs, and agents. Users can download the app for free, try it with over 50+ model providers, and easily share their setup with their team.

You should only be paying frontier model prices for top-shelf reasoning. But 88% of your token bill is just tool I/O. Quotient Labs runs on top of Claude Code to reduce token spend, compress context, and optimize tool calls while preserving output quality. Same models, same workflow, no changes to how you work. Benchmarked 47% less cost on real, multi-step developer workflows, with no quality loss.

Robby is an AI growth engine for home services businesses that uncovers revenue opportunities and collects additional data from every technician visit. Our AI combines customer and third party data to generate dozens of new leads every day, and then arms the technicians with talking points to increase close rates, giving GMs a single command center to manage and drive revenue. We have several paying customers that are each uncovering 6 figures in additional revenue opportunities every week. On our first day of launch, we helped close $40k in new business within an hour. Our team has spent the last few months riding along with dozens of technicians and shadowing every position in the office to best understand the industry. We're also studying for the EPA 608 exam to become certified technicians ourselves. Vineet and Feroze have both built critical products and infra at prominent startups (Ironclad, Porter, Affinity, Uber, Cloud Health Systems). Joe previously consulted PE firms on software acquisitions and led home services growth projects at Bain. We all met at Harvard Business School, and dropped out to work on Robby full-time.

Unisson is building trusted AI subject-matter experts for teams that are responsible for customer deployments (technical customer success, implementation, sales engineering).

With Unisson, customer-facing teams have 24/7 access to an AI SME, allowing them to scale and save thousands of hours.

Logical is a desktop AI that acts as a proactive and largely promptless copilot, designed to reduce the friction of using AI for everyday tasks. It transfers context across apps, and allows taking action on many apps with just a few clicks. Logical can assist with drafting emails, writing docs, noting meetings and can even automatically detect action items. Need to prompt? Logical can understand intent in much fewer words than a regular chatbot. Plus, user data is never sent to Logical servers. Logical is the AI resurrection of Clippy, but actually good.

Clicks Health builds AI agents that automate back-office operations for RCM companies and healthcare providers. Our agents work across EHRs, payer portals, desktop applications, and legacy systems, following existing processes, handling exceptions, and escalating when human judgment is needed. Backed by Y Combinator, Clicks helps teams improve accuracy, shorten turnaround times, and reduce operating costs, with SOC 2 Type II and HIPAA compliance built in.

AI that helps you fly through your inbox.

Magnetic scans client documents - from handwritten charity notes to excel spreadsheet Schedule Cs to multi-state K-1s - and enters them into tax software automatically, saving hours of tedious data entry. The accounting profession is facing a massive talent shortage, as graduates choose different professions and the old guard begins to retire. As a result, CPA and tax preparation firms are awash in clientele, but unable to keep up. At many firms, phones go unanswered, clients are "fired", and websites are taken down, as the existing workforce tries to handle the grueling 80 hour+ weeks necessary to push through tax season to the April 15th deadline. We built this because a former colleague who owns her own tax firm asked us to automate her workload, and we quickly realized the massive opportunity. Thomas brings deep domain expertise as the former Head of Product at Keeper (YC W19), where he built tax engine automation systems and an OCR form scanning system that outperformed everything else on the market. At Keeper, he leveraged early access to OpenAI's LLMs (well before ChatGPT) to build systems that automated the entire tax filing process, allowing a tiny team of CPAs to process thousands of returns with near zero busy work. Patrick was the first engineer at FunCraft, shipping multiple mobile games with 1M+ downloads and building scalable shared codebases. We've worked together since 2017, including co-leading multiple teams at Zynga as PM & Tech Lead respectively. The opportunity is massive - there are 80M US personal tax returns filed via professionals annually, in a $2B outsourcing market where individual CPA firms currently pay $100k-$1M per year for inferior services. We're positioned to capture significant market share by offering better accuracy & document coverage, instant processing, and superior user experience. We've built this kind of software before, we've worked together for years (and even lived together), we've built products to $10M ARR before, and we have the grit to outwork anyone in this space.

OrgOrg is a suite of apps that keeps teams productive and healthy regardless of the size of your organization. Founded by the creator of Zenter (YC 07, acquired by Google and became Google Slides), OrgOrg is designed to be a natural extension of Google Workspace Apps to help run organizations collaborate better leading to higher productivity. Today the suite includes apps like: • Go links: Go links allows anyone in the org to easily name any link so team members can jump directly to the information that matters most: go/sales, go/production, go/anything-you-want. • Profiles with Personality: OrgOrg profiles are as insightful as they are delightful. They not only show you the expected org chart data, but also highlight accomplishments, how you like to work, and who you are as a person. • Goal tracking: Track, share, and collaborate on "big rock" goals on the cadence that makes sense for your team from daily to annually. • Branded New Tab: Keep the team focused the next major milestone, broadcast announcements, and keep important links top of mind every time a new browser tab is opened. • All Hands Q&A: Crowdsource questions, anonymously if desired, for large team meetings to make sure everyone's voice is heard, and the most top of mind questions are answered and recorded. • Smart Groups: Create rules based groups of people and use them to make sure the right people are in the right conversations and have the right access. For example, anyone with the title of "Software Engineer" should be in the #eng slack channel and eng@ google group. • On-call: Schedule smart rotations that take into account balancing the load and using signals from calendar schedules to make sure you don't waste time figuring out who can cover what in a fair way. Easily page the on-call from slack, API, or OrgOrg directly. • And more... All the tools you need so you can spend more time focusing on your core business, and less time focusing on the complexity that comes from running an organization.
