From a garage to a global empire You started with a laptop and an idea. Idle Startup is a relaxing incremental game about growing that idea into a tech company — one completed task at a time. Pick a skill, and it goes to work. Progress bars fill, XP rolls in, money stacks up. Spend it on upgrades, level up, and watch new skills and whole departments unlock as your company grows. Every skill is its own journey Each of the six skills has its own upgrade store — a tree of nine upgrades gated by skill level and cost. Most boost that skill alone, but every skill hits milestones at levels 25, 50, 75 and 99 that reward a permanent, company-wide bonus. There's always a reason to push one more level. Simple to start, deep to grow The whole game makes sense in under a minute — select a skill, earn, upgrade, repeat. But there's always a next unlock: a costlier upgrade, a milestone, a new department, the next achievement. Max a skill out and it keeps earning Mastery , a slow bonus that never stops growing. Always progressing Idle Startup respects your time. The game keeps earning while it's closed (up to 4 hours), and a free Coffee Break speed boost is yours to claim a few times a day. Your save syncs through Steam Cloud, so you can pick up on any device. Optional boost packs (you don't need them) Three small optional purchases let you skip ahead if you want to: an Energy Drink for a 2× speed boost across four hours, a Coffee Pot for a full 24 hours, and a one-time Productivity Suite for a permanent 2× speed boost and unlimited offline earnings. None of them are required — the whole game is playable and completable without spending anything.
