ProductPath icon

ProductPath

Turn enterprise signals into product direction

ProductPath is a product intelligence workspace that connects disparate feedback channels — app reviews, customer service tickets, surveys, seller reports, and social media — into one unified stream. AI clusters thousands of raw items into themes, tags severity and sentiment, and prioritizes opportunities with evidence behind every recommendation.

Built for product managers drowning in fragmented feedback, ProductPath replaces gut-feel prioritization with statistical confidence. Every insight traces back to source data, every AI answer reports its sample size, and teams can track whether each release actually moved the needle.

  • Unified inbox across every feedback channel with AI-tagged themes
  • AI clustering into themes with severity, sentiment, and trend tracking
  • Evidence-backed prioritization scoring, not loudest-voice-wins
  • Release impact measurement with statistical significance indicators

GroupTripper

Plan group trips together, effortlessly

GroupTripper is a collaborative trip planning app that makes coordinating group travel genuinely fun and easy. Friends and family can build a shared itinerary together — adding flights, accommodations, and activities to a day-by-day calendar that everyone can see and edit in real time.

As founder and builder, I designed the full product from concept to launch on both iOS and Android, including a built-in AI Travel Agent that generates complete day-by-day itineraries based on destination, travel themes, and group size.

  • Collaborative itinerary builder with real-time updates
  • AI Travel Agent for instant day-by-day trip generation
  • Group idea voting — suggest, vote, and schedule to the calendar
  • Shared expense tracking across the whole group

Family Kinnect icon

Family Kinnect

Your family's wellness, synced

Family Kinnect is an iOS app that lets families stay connected through health. It surfaces each family member's key daily health metrics — steps, heart rate, sleep, and activity — in one shared dashboard, so you know at a glance when someone might need a check-in.

The AI-powered 'At a Glance' summary reads health patterns each morning and tells you in plain language whether today's a day to push, pace yourself, or rest. Home screen widgets and smart alerts give everyone exactly the information they want without the noise.

  • Shared family health dashboard — steps, heart rate, sleep, calories
  • AI-powered daily readiness summary with personalized guidance
  • Smart alerts and one-tap check-ins when someone looks off-track
  • Home screen widgets and per-member notification controls

Momentus icon

Momentus

Capture the moment. Keep the momentum.

Momentus turns real-world conversations into clear AI notes, action items, decisions, and follow-ups — starting with one tap from your Apple Watch or iPhone. It's built for the conversations that matter most: client meetings, workshops, discovery interviews, field visits, and advisory sessions where pulling out a laptop isn't practical.

Unlike meeting bots designed for Zoom and Google Meet, Momentus is built for in-person conversations first. It records locally, transcribes with speaker awareness, and uses advanced AI to generate structured summaries you can actually act on — all while keeping your data private by default.

  • Start recording from Apple Watch or iPhone with one tap
  • Speaker-aware transcripts with timestamped segments
  • AI summaries with decisions, action items, risks, and follow-ups
  • Local-first storage — private by default, no account required
