Hotel know-how, artificial intelligence and an experienced team in one. ASTOR helps you see the connections and decide with confidence. From room rates to the last item on the menu.
Twelve skills.
The whole hotel under control.
ASTOR21 has twelve specialised skills — each covers one area of the hotel. Depending on your question the right one activates: sometimes it speaks as an investor, sometimes as a head chef, sometimes as a revenue manager.

Why ASTOR
Why ASTOR pays off
for every hotel.
ASTOR runs on Claude models from Anthropic — one of the world's leading AI developers. We have built hotel know-how into these models, so ASTOR does not just understand general questions, but your specific operation.
ASTOR does not just report problems — it proposes solutions with a direct impact on results. Every answer contains a concrete, prioritised action, not just an analysis of spreadsheets.
ASTOR is backed by the BC21 team and years of hotel experience. You are not buying a licence you have to learn — you get a solution with support behind it.
ASTOR automates repetitive analysis and administration — from pricing through food cost to shift planning — and keeps looking for where operations are overspending. The result is lower operating cost and more time for guests, not for spreadsheets.

Good morning. Today's situation is stable overall, but there are two things that need your attention before the meeting.
Bookings for the next 7 days are +11% above last year — a strong weekend is coming. The rate holds at CZK 4,200, guest satisfaction over 30 days is +72. Direct bookings are at 45% of the total, above target.
1. Payroll cost: Last week 22% — at the target ceiling, but the trend is rising. Housekeeping overtime +18% versus the previous month. It needs a plan this week.
2. Room 14 out of service since Saturday — air-conditioning fault. The technician arrives today at 11:00. The guests booked into room 14 arrive on Wednesday — shall I prepare an upgrade to deluxe?
I analysed the structure of payroll cost over the last 90 days. Base salaries are not the problem — they hold. The problem is overtime overload in housekeeping and weak cover when a team member is absent.
Housekeeping overtime accounts for an estimated 60–70% of the total increase. If the trend continues, we will reach 24–25% by the end of July, which is the level that triggers the investor's attention.
Cross-training plus flexible help depending on occupancy. Back on target within 6 weeks.
Shift review plus limiting overtime. Back to normal by the end of July.
No intervention during full holiday operations. A significant hit to Q3 profit.
Bookings for the next 7 days are +11% above last year. The weekend is 78% booked — 2 days in advance. Comparable hotels nearby raised their average rate by 8–12% versus the previous weekend.
Recommended move: CZK 4,450–4,600 for the remaining 7–8 free rooms.
Rate CZK 4,600, 8 rooms for 2 nights. Fully booked.
Rate CZK 4,450, 5 remaining rooms.
Some guests go to competitors if the increase is too steep.
The realistic scenario = +CZK 17,500 revenue for the weekend without a single extra guest.
Not an app.
