BuysideBUYSIDE

Investment banking runs on pitches, diligence, valuation and negotiation, and most people never see any of it. Buyside turns each one into a mechanic you can play.

Pitch

A card game against founders with hidden tells.

Diligence

A document-flip mini-game.

Valuation

Set a price on a football-field chart.

Negotiation

Poker-style, against buyers who each have a hidden walk-away price, while three rival banks compete for the same mandates.

• 

  Pitch and win bake-offs

  Read the founder's tell, play the cards they love, and beat three rival banks to the mandate.

• 

  Run auctions and bidding wars

  Line up buyers, push the top bidder, and squeeze every last dollar out of the deal.

• 

  Grow from a garage to a penthouse

  Hire a team, survive rival raids, and move up from a garage boutique to a penthouse tower.

Plain HTML, canvas and vanilla JavaScript: about 24,000 lines across 6 modules, with no build step and no dependencies. Every graphic is drawn in code. A Node harness plays full simulated seasons to check the cash ledger and the balance.

The same code ships with Capacitor 8: haptics, on-device saves, pause on background, and a landscape layout that runs under the notch while the HUD stays in the safe area. Builds go to TestFlight.
