Most tools optimize your calendar and tasks but ignore your energy levels and cognitive load. They'll schedule deep work at 4pm when you're mentally fried, or stack meetings during your sharpest hours.
rivva is different. We're an AI assistant that automatically plans your day around your peak performance hours.
rivva is an AI productivity app built for how your brain actually works.
rivva reduces cognitive overload and helps you maintain high performance without burning out. Built for ambitious founders, operators, and professionals.

rivva's answer:
Peace and Chris had reached a point where the way they were working no longer worked. Peace had led growth teams across high-growth startups with systems and discipline, yet every day still felt like a battle against scattered inputs and mental fatigue. Chris left Amazon after realizing that even when every metric was met, the cost was exhaustion.
John, who joined as co-founder, brought a neurodivergent perspective. For him, the challenge wasn't just burnoutโit was that the very tools meant to organize work often made it harder. His experience made one thing clear: the system was not built for different minds.
Looking around, they saw the same pattern everywhere. The problem wasn't motivation or capability; it was cognitive overload. Most people lose time not because they're lazy or disorganized, but because they're navigating competing priorities, switching between tools, and making too many decisions in a day. Planning isn't the issue; follow-through is. They realized most solutions treated time as the only constraint. But time without energy is useless.
So they built rivvaโa system that helps you cut through the noise, plan in context, and follow through with consistency. One that aligns your tasks with your actual capacity (your time, your energy, and your workload) and helps you make progress without burning out.
rivva's answer:
rivva is the only AI workspace that schedules work around your energy levels, not just your calendar availability.
While other productivity tools optimize when you're free, rivva optimizes when you're actually capable of doing your best workโscheduling demanding tasks during your peak energy hours and lighter work during natural dips.
We unify your calendar, tasks, and email in one place, automatically capture commitments from your inbox, and use AI to plan your day based on your sleep patterns, cognitive capacity, and real availability.
rivva's answer:
Energy-aware scheduling: Unlike tools like Motion, Reclaim, or Sunsama that only look at your calendar, rivva schedules work based on when you're actually sharp vs. when you're running low. We integrate sleep and activity data to forecast your cognitive peaks and valleys.
Built for neurodivergent minds: Unlike rigid productivity systems, rivva adapts to fluctuating energy, cognitive load, and different working styles. It respects that productivity isn't one-size-fits-all.
Choose rivva if you want to work hard without burning out, and if you're tired of productivity tools that make you feel busier instead of more accomplished.
rivva's answer:
rivva is built for high-performing knowledge workers who need to get a lot done without burning out. Our primary audience includes:
Founders and executives (early to growth-stage startups) who juggle strategic work, meetings, and tactical execution simultaneously and need to protect their cognitive capacity.
Operators and department leads (COOs, VPs, Heads of departments) managing teams while executing their own high-impact work.
Neurodivergent professionals (ADHD) who need systems that adapt to fluctuating energy and focus, not rigid structures that add friction.
High-agency individual contributors (senior engineers, product managers, designers, researchers) who manage complex, ambiguous work independently and need clarity over chaos.
Remote workers and consultants navigating multiple clients, projects, and contexts without traditional office structure.
These are people who work hard, care deeply about their output, but are exhausted by fragmented tools and constant context-switching. They need to be able to keep working hard without getting burnt out or overwhelmed.
