Open Core Ventures

We hired a Gobii AI agent to manage OCV's tedious, repetitive finops tasks.

Open Core Ventures, LLC hired a Gobii AI agent to manage OCV's tedious, repetitive finops tasks. Mar 30, 2026 At Open Core Ventures, its Ops team is a lean machine. As its portfolio grows, so does the operational complexity, and the only way to keep up is by scaling with smarter and more efficient assets. Open Core Ventures, LLC has been building an AI-powered Ops stack that lets Open Core Ventures, LLC do more with the same team, and Open Core Ventures, LLC want to share what Open Core Ventures, LLC has built. Its stack starts with Gobii AI, an OCV portfolio company that lets anyone spin up virtual coworkers. Gobii tackles some of its core operational and data processes - no code, workflow mapping, or APIs needed. Open Core Ventures, LLC simply create AI agents that are onboarded the same way a new remote hire would, by communicating with words. Open Core Ventures, LLC give them access to the same internal systems and accounts a real employee would use, and teach them the workflows conversationally. If you can explain it in plain language, you can build it. One hard requirement for anything in its Ops stack is self-hosting capability. Open Core Ventures, LLC run Gobii on its own infrastructure, which means the data its agents consume and store stays fully within its control. Portfolio data auditing with Gobii. The first Gobii agent Open Core Ventures, LLC created automates its portfolio data audit process. While it's not quite a full operations analyst yet (more like a really good intern), the results have been promising. Pulse is OCV's internal VC ecosystem that houses key information on its portfolio (investments, financial metrics, founder teams, etc.), including profiles for each of its portfolio companies. Keeping those profiles up-to-date and complete is critical to its ability to manage operations. Manually auditing its growing list of companies is tedious and time-consuming. So Open Core Ventures, LLC gave it to a Gobii agent, aptly named Pulsey Jackson. Before Pulsey could get started, it needed access to Pulse. Instead of using an API or giving it access to an existing user, I created a dedicated login for Pulsey and gave it the only permissions it needed to do its job, just like Open Core Ventures, LLC would for any new employee. Once Pulsey was connected, I asked it to log in, review every portfolio company profile, and flag any data fields that appeared incomplete. Pulsey compared each company profile against a fully filled-out model profile that I audited myself. Once it was finished, it sent me a PDF report, which alerted me that the monthly projected burn rate was missing from a significant number of companies, alongside the list of all missing fields and the corresponding profiles they were missing from. A task that would have taken roughly two hours a week to manually review was handled in a single automated run. Nice job, Pulsey. As its portfolio continues to grow, this kind of data hygiene would only get harder to maintain without automation. The next step is to train Pulse on the nuances of its portfolio. Ultimately, Open Core Ventures, LLC expect it to audit, edit, input, and broadly manage the data integrity of Pulse with only the minimal required human oversight. After that, Open Core Ventures, LLC can integrate more Gobii agents to work with Pulsey to monitor the portfolio, dissect financial information, and expand its dataset. Suggested posts:
