Our test · October 2026
We wrote to 30 agencies as a foreign buyer.
One Saturday evening on the Costa del Sol, by WhatsApp, web form and email. This is what came back.
When the listing isn't exclusive, the buyer has written to three agencies. The viewing goes to the first one that answers.

Calculator
How much commission leaves with the buyers nobody answers?
Five questions. Same model as our audit.
In our test, 8 of the 30 agencies we wrote to on a Saturday evening got a person to answer.
Estimates from UK and US data; the audit redoes it with your agency's real replies.
How we calculate
Model: buyers write from 08:00 to 24:00; after 22:00 and on Sundays we count half as many. 30 % of out-of-hours messages get no answer in time. One sale per 100 enquiries. Synaptik wins back half. Cost: Viewings plan, first year: founding €490 × 12 = €5,880, or normal €590 × 12 + €990 setup = €8,070.
A sale takes 3 to 9 months to close. Founding price includes setup.
Plans
Three plans. We recommend Viewings.
It takes a buyer from the first message to your agent, screened and summed up.

FAQ
What agency owners ask us.
Does it sound like a bot?
It replies with your agency's name, like someone on your team. It asks two questions at most and hands the buyer to your agent. If a buyer asks whether they're talking to a person, it tells the truth and hands over to an agent.
How much work is it for my team?
In the setup week, one call and access to your listings. After that, your agents only get the buyers worth calling, each with a three-line summary, and you read one report on Mondays.
What if it says something wrong?
It only talks about the listings in your stock and never gives prices or discounts that aren't in the listing. If it doesn't know something, it passes the buyer to a person.
We review 50 real conversations in the setup week, and every Monday you see what it said.
Do I lose my WhatsApp number?
There are two ways. If Meta's coexistence works with your number, you keep using the app and the assistant answers when you can't. If it doesn't, we give you a new number for the assistant.
Coexistence works in Spain. We check it with your number before you start
Does it work with Resales?
Yes. It reads your listings straight from Resales Online, by reference, area and price, and never offers a home that is sold or reserved. Without Resales, it answers from the listings on your website. If you use Inmobalia or Inmovilla, it works with those too. If you use another program, we tell you within 48 hours whether it fits.
What about my buyers' data and GDPR?
We use the official WhatsApp API, with your agency's number or the assistant's new one. The data stays in your account and stays yours if you leave. Before you sign, we give you in writing what data we store, where, and who is responsible for it.
Data processing agreement: in preparation
Can I cancel?
Yes. Regular plans are month to month, without penalty. Founding places have a 3-month minimum in exchange for free setup and a price frozen for 12 months. The 30-day pilot comes with our guarantee: if we miss one of the three numbers, you get the month back.
