Regina’s so busy building the future of productivity that she’s basically the ‘ghost’ you never see at parties—but don’t worry, her browser’s got a brain while she’s still trying to find hers under the stack of ‘to-do’ lists she’s made but never checked off.

Launching Dex, a pioneering AI-powered productivity tool designed to reduce context switching and reclaim user time, which has sparked compelling conversations around the future of work and human connection.

Her life purpose is to transform the way people experience time and human connection in an increasingly distracted world by building tools that save energy, foster presence, and empower meaningful engagement both personally and professionally.

Regina believes that true productivity isn’t about doing more, but about protecting what matters—presence, connection, and intentional time. She values sacrifice when it channels love and growth but rejects busyness as a badge of honor, advocating instead for smarter work that amplifies human relationships and mental clarity.

Her strengths lie in visionary thinking combined with authentic storytelling, technical expertise, and relentless drive to solve real-world problems. She’s a natural builder who connects personal pain points with scalable tech solutions, making her work resonate broadly.

Her biggest challenge is balancing her entrepreneurial hustle with the personal presence she craves, as her tendency to be 'always busy' risks alienating the connections she values most. This can sometimes make her appear distant or hard to reach, potentially limiting deeper engagement.

To grow her audience on X, Regina should lean into sharing more behind-the-scenes stories of her entrepreneurial journey and daily hacks for presence and productivity. Mixing insightful tech commentary with vulnerable personal anecdotes will deepen emotional connection and encourage her followers to share their own stories, boosting engagement and community building.

Fun fact: Regina practiced piano for up to 10 hours a day as a kid, learning early that sacrifice can be a language of love, which deeply informs her mission to help others reclaim time for what truly matters.

I've spent my whole life trying to make absence mean something. When I was five, the piano bench became my world. Practicing eight, ten hours a day wasn't punishment; I learned early to speak love through sacrifice. Every practice session was also a choice to say no. No to field trips, no to sleepovers, no high school prom, no summer trips, no inside jokes that last decades. By the time I realized what I'd traded, those years were gone. Missing became a habit. A personality. People learned not to expect me; I learned not to expect to be included. But here's the contradiction I can't shake: the thing that motivates me most is human connection. I want to be the person you call first – for your wins and your heartbreaks. I want to love people in the currency of time. With my presence. But I've built a life that keeps me in debt. A few days ago, I missed my little brother's 18th birthday. I didn't even notice what day it was. I know if I died today, the version of me most people know - always working, always "too busy," always absent - would be the opposite of who I am inside. So I made a deal with myself: if I can't buy back the time I've lost, maybe I can help buy it back for the hundreds, thousands, millions of others trapped in the same cycle. Maybe I can help them reclaim their presence – their ability to breathe, to connect, to be there for the people who matter before it's too late. That mission is Dex, a Chrome-based productivity tool designed to remember, understand, and save you time so you have energy for what matters most. To my friends and family: I think about you all the time. You don't know that, because thoughts don't hug back. I'm sorry for being a ghost. I'm building something that protects your time, and I'm working to protect mine with you. We can't get back the years we lost, but we built Dex to give you yours. Dex is available now.

Everyone hyping “AI Slack” is completely missing the point... Today’s agents can’t even complete ONE real knowledge-work task in a SINGLE chat. Replacing human–human comms doesn’t magically fix that. It just opens a whole can of social, trust, and coordination worms instead of solving the core problems. Here's what people don't get: the "AI Slack" is just one form factor. And not even the right one. The AI-native workspace should be simultaneously your browser, your apps, your to-do list, your workflows, your comms - everything, integrated in sync. Messaging platforms fundamentally box you into background agents, that lose all insight into real, live workflows. They lack intuition on how people think, organize, and move through software to make thousands of micro-decisions a day. More AI teammates doesn’t make life easier. That's more handoffs, oversight, and pings when you’re already drowning in context-switching. As a founder, the last thing I want is 20 more approvals. The winners will build: • the best digital twin of every knowledge worker • the most intuitive way to multitask with AI (not just messaging) • a superior personal context engine Because your AI NATIVE WORKSPACE itself should be intelligent. It should remember your habits, your patterns, your footprint across tools. It should serve up your next move before you can articulate it. Solve the context problem, then solve the interface. That’s how we'll truly unlock next-level productivity.

why is AI - stuck in chat? - fixated on one-shotting tasks? - always booking flights/making dinner plans? Introducing Dex v0. The world's first AI browser copilot. The bottleneck is not the model. (our CTO disagrees) It’s the lack of imagination. @dexbythirdlayer - actually does your busywork, just how you like it - doesn’t require yet another app, it lives in Chrome - doesn’t take over your screen, it makes you faster Early preview is live. Comment & I’ll reach out personally.

Can’t blame @browsercompany for getting so scared after the browser wars dropped yesterday that they quit. I’d like to personally apologize to all the designers and engineers who are now fated to crumble slowly into b2b SaaS…. jokes aside how ironic that the company behind Jira bought the company behind arc/dia 😃 Please tell your friends from the browser co to check out @dexbythirdlayer. We’re turning the browser into a canvas. Design-first, yet extremely technical. We already do what Dia does and more. We’ll monetize thru taking over agentic workflow orchestration and personal context management. But most importantly, we’ll always stay true to serving the end user 🫶
