The event operations platform

Built for hosts.
Trusted by pros.

Plan, design, sell, run, and settle every event on one platform — with five AI agents working as your crew. Whether you're throwing a 40-person fundraiser or producing a 5,000-seat conference, Hosta runs the operation.

The platform behind every great event
One platform, two operators

The same engine powers a bake sale and a brand conference.

Complexity is opt-in. The interface reveals only what your event needs — so a first-time host sees five tabs, and a production team gets the full operations stack.

Simple mode

The first-time host

You're planning the fall fundraiser, a quinceañera, or the company offsite — on top of everything else. Tell Hosta what you're throwing, and the AI builds the plan.

  • Five tabs. No jargon. The AI interview sets up everything from one conversation.
  • Checklists, budget, and guest list generated from natural language.
  • A seating chart your venue can actually use.
Pro mode

The event producer

You manage a portfolio of events across clients, vendors, sponsors, and crews. Hosta is your CRM, your BEO engine, your show-caller, and your back office — one login.

  • CRM, contracts, e-sign, multi-event pipeline, team permissions.
  • BEOs, vendor timelines, COI tracking, Stripe Connect payouts.
  • White-label client portals and full operations API.
For every kind of host

Every event deserves a real production.

A sweet sixteen. A nonprofit gala. A product launch. A 5,000-seat conference. The same operational rigor. The same friendly AI crew.

Hosta runs the operation. You take the credit.

Watch the AI set up a real event.

This is Scout, our sourcing agent. Tell it what you're throwing and it interviews you, drafts the budget, finds venues, and queues the contracts — in under a minute. The version below is on a loop; in the product, it runs once and lands you straight in the dashboard.

Powered by the same Anthropic API that runs the rest of the platform. You can dial down its autonomy at any time.

Day-of autopilot

Scroll through a real event day.

Stage Manager — one of five AI agents — watches the run of show, recalculates every dependent task when something slips, and pings only the people who need to know.

The platform

Five phases. One source of truth.

A guest's "vegan, wheelchair" note from registration updates the seating chart, the kitchen sheet, and the place card — automatically. Nothing lives in two systems.
