Top Tech Startups in Silicon Valley in 2026

Ivo was founded by a contract attorney and built by a team of lawyers, technologists, and operators with deep experience in contract work. We've experienced firsthand how manual, fragmented contract workflows slow down business, introduce risk, and drain legal teams. That perspective informed our flagship product: an AI-powered redlining tool that helps teams move faster—without compromising legal judgment. Since then, Ivo has grown into a broader platform, serving not just in-house legal teams, but also procurement, sales, and other key business functions. In addition to AI redlining, our suite includes a smart repository for organizing and managing contracts, and a powerful agentic assistant that helps teams get answers fast—always backed by source-grounded context. Originally founded in New Zealand and now headquartered in San Francisco, Ivo is backed by top-tier investors and trusted by global enterprises and fast-growing startups. We’re proud to support some of the most innovative teams in the world at companies like Pinterest, Quora, and Canva—and we’d love to support yours, too.

Outpost.red is a hyper-specialized tech-enabled Reddit marketing agency. We help brands show up in the right Reddit conversations, post in a way that feels native to the platform, and turn Reddit into a real growth channel. Our work is focused on Reddit, but the impact goes beyond Reddit itself. Strong Reddit presence can influence brand trust, buyer research, Google visibility, and AI-generated answers across platforms like ChatGPT, Perplexity, Claude, and Gemini. We work hands-on with clients to identify the right opportunities, develop content angles, write posts and comments, manage execution, and measure results. In plain terms, we help companies earn attention and trust in the places where buyers are already asking questions, comparing products, and looking for honest opinions. We are not a traditional social media agency, and we are not a spam shop. We care a lot about quality, judgment, tone, timing, and understanding how Reddit actually works. Good work on Reddit requires nuance. It requires knowing when to engage, what to say, how to say it, and when not to force it. We are building a new kind of agency: tech-enabled, operator-led, and deeply focused on one channel that most companies still do badly or ignore completely. That means our team sits at the intersection of marketing, operations, content, research, and product. We use software and AI internally to move faster and work smarter, but the output still depends on sharp people with good taste and strong judgment. If you join Outpost.red, you will be working on a focused problem in a fast-moving market, with real responsibility and high standards.

Tasklet is building the AI platform companies use to run their business on agents. Our customers describe an outcome in plain English, and Tasklet gets the work done—across SaaS tools, APIs, browsers, files, spreadsheets, and internal systems. Agents can respond immediately or run business processes in the cloud 24×7 on a schedule or in response to events. Every Tasklet agent gets its own cloud computers, filesystem, database, and browser. Tasklet agents are built to do real work at real companies where many people are involved in each function. Teams share agents, knowledge, connections, and conversations, while administrators control access, behavior, and spend. Tasklet users can choose among models and delegate work to faster, cheaper ones—giving companies one flexible platform instead of a growing pile of disconnected AI seats. We compete with ChatGPT Work and Claude Cowork. OpenAI and Anthropic have their own models, massive funding, and existing distribution. We have a small, exceptional team, the freedom to use the best AI tech from any vendor, and a laser focus on the problems of real-world businesses where making agents simple, trustworthy, and easy to control matters just as much as making them intelligent. The labs will define what intelligence can do, but Tasklet will define how businesses put that intelligence to work.
