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.

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.

Caro is the single source of truth for headcount that aligns finance, recruiting, and hiring leaders. As companies scale, the cost of the team (headcount) becomes their greatest expense (75%+ of spend for tech companies). Consequently, finance teams need to be vigilant about monitoring these costs. However, recruiting teams and hiring leaders are incentivized to hire quickly to ensure teams are sufficiently staffed so that they can deliver on their goals. This creates a tension between hiring velocity and spend management - a problem that exists in every company, resulting in hundreds of spreadsheets to reconcile data between the different teams and their different systems involved. Caro is backed by tier 1 investors: Accel and Lightspeed. We're proud to be trusted by leading tech companies like Affirm, Discord, and Intercom.
