Colorado first. iPhone first. In bounds.

A guide for the day on the mountain.

Cached, honest, and yours when the lift cell drops out. Five Front Range resorts, one winter.

Prelaunch mountain intelligence

Skiisu is being built for skiers who know their taste, but do not want to spend Friday night stitching together tabs, forecasts, and half-remembered mountain notes.

How it works

You bring the day. Skiisu keeps the plan grounded.

01

Tell us the kind of day you want.

Fast laps, blue cruisers, bumps, family pace, partner mismatch, short window. The day intent matters as much as the pass in your pocket.

02

Compare the five Front Range calls.

Skiisu weighs mountain fit, conditions, weather pressure, and your profile before it suggests a resort to consider.

03

Keep the plan honest when service fades.

The intended morning packet is designed for weak service. If data is old, missing, or low confidence, Skiisu says that plainly.

What you get

Where to ski. What to ski. What changed.

The first product is not a stats trophy case. Feedback exists so Skiisu can learn which terrain you repeat, which pitches you avoid, and when a plan needs to bend.

  • Planner recommendations across the five-resort V1 cohort.
  • Terrain and pace notes only where the supporting resort structure is strong enough.
  • Local day adjustments for tired legs, lunch, weather discomfort, or a partner who wants a different pace.

V1 scope

Five resorts, chosen on purpose.

Colorado first on purpose. We'd rather be right about Copper than pretend the whole ski map is solved.

The one we know best

Copper Mountain

The strongest mountain knowledge of the five, with directional terrain calls, weather pacing, and named-run planning.

The close call

Eldora

The practical Front Range choice where wind, drive tolerance, and a shorter ski window can matter more than romance.

Two-mountain day

Winter Park / Mary Jane

A bigger canvas for matching bumps, trees, cruisers, and day rhythm without making you study the map all morning.

Still learning the big one

Breckenridge

In the V1 cohort, with clear labels where Skiisu is still learning the mountain more carefully.

In, with limits

Arapahoe Basin / A-Basin

Part of the V1 resort set, but still early. We show the mountain record we have and label what we do not know yet.

Honest by design

We do not guess at lift lines.

We do not pretend to know lift-line length, terrain opening timing, delayed openings, or live drive time when the required data is not there.

When weather, resort knowledge, or plan inputs are stale or weak, we label them that way instead of dressing up an old answer as a fresh one.

Weak service is normal

The lift cell drops out. The plan should not.

Skiisu is being shaped around a cached morning packet and bounded local changes. Not as a fallback, but because mountain service is part of the terrain.

Made from the Front Range problem

Built for the skier comparing too many tabs on Friday night.

Skiisu starts with a familiar Colorado question: is tomorrow a Copper day, an Eldora day, a Mary Jane day, a Breck day, an A-Basin day, or a stay-home-and-save-it day? We earn trust by being useful there first.
