Dex is a personal CRM that reminds you to keep in touch with the people you would otherwise forget. Dex helps turn your acquaintances into your allies. Going beyond the superficiality of social networks requires commitment. If you remember to keep in touch thoughtfully, you can turn the interesting person you met at a networking event into a friend that has your back. I built Dex after failing to keep up with the tools I tried (Airtable, Notion, etc) for relationship management. Installing an actual CRM like Hubspot felt like a wrong fit for my informal relationships -- these people were 'my team,' not customers. Dex is a lightweight personal CRM that’s easy to stick with. Key to Dex is a Chrome extension that enables you to manage relationships while you’re in Facebook, Messenger, Twitter, and the social apps you already use. Dex can also send you actionable reminders (daily, or based on your calendar events) to log your interactions for next time. By using Dex, you can: - Build stronger relationships, by sending you a nudge to follow-up. - Be more thoughtful, by helping you remember where you left off. - Become a superconnector, by making connections you wouldn’t otherwise remember.

Recurrency is reversing enterprise resource planning (ERP) stagnation by building the industry-standard ERP automation platform: blazingly fast and complete with powerful automation tools like intelligent sales recommendations, dynamic pricing, and demand forecasting.

Using Recurrency can boost a distributor’s revenue and profit margins, while reducing waste and saving time. Most importantly, Recurrency is fully integrated with the customer’s legacy system, so deploying Recurrency in production can be done in as little as one day.

With Velt, we're setting out to reverse these figures, reducing time spent on logistical issues by over 90%. Imagine what we can create when we spend less time talking about work and more time doing it! We're building a better web—a web for us, for our team, for everyone.

We help B2B companies reduce churn and grow customer spending. Our product gives account managers access to data dashboards and priority checklists needed to proactively save customers and upsell them to more profitable products.

Workbase is the solution, by one-click integrating the data sources and customizing the interface and actions for each company. When working on similar internal tools at companies like Segment, we saw first-hand that proactively managing the customer journey could increase net retained revenue by as much as 20 percent.

Satsuma is a developer tool for building applications on top of real-time blockchain data.

We’re a founding team of engineers, having built data infrastructure and product as early employees at Airtable, Heap, and Y Combinator.
