What Factorial launched with One

Factorial presented its quarterly launches, with One at the center, in its quarterly launch video, posted on LinkedIn by its co-founder, Bernat Farrero.

This post covers the launch in detail. The comparison with Aindez is in AI agents, whatever HR system you use.

What it is

One is Factorial's personal agent. It runs any feature of the platform, reads and creates files, analyzes data, builds dashboards and runs scheduled routines.

It isn't new: Factorial presented it in October 2025. This launch adds, among other things, phone calls.

The bet

Bernat Farrero says it at the start of the video: One can replace subscriptions to generic AIs like Claude or ChatGPT, at costs "better than the generic subscriptions" and under the policies the company sets.

The idea is that a Factorial customer shouldn't need another AI tool.

The two demos

Both were real-time phone calls. Bernat Farrero played the worker in one and the candidate in the other, on his own phone.

1. Shift replacement. Carlos says he can't make his Thursday shift. The manager opens the shift and asks for a replacement. One builds the list of people who can cover it, in the configured order, and the manager can change that order before starting.

One calls the first person, says the call is recorded, offers the shift and, once they accept, assigns it in Factorial. The settings define how many retries each person gets, what hours they can be called and through which channel.

2. Candidate screening. A candidate moves to the first evaluation stage and One calls her. It asks for consent to record, confirms her experience, asks the profile questions and answers her question about pay with the job's salary range.

When the call ends, she is already in the interview stage, with the recording and each requirement marked as met. Factorial says One can call the whole pipeline at once, with as many retries as you want, even at the moment someone applies.

Everything it announced

Beyond the demos, the video walks through almost every Factorial module.

Communications

• Video calls, calls and messages inside Factorial, in groups by office, team or work site.
• One writes on someone's behalf, with a record of what it sent.
• It's designed for operators and staff who don't work at a computer.

The personal agent

• It creates images, reads and creates files, searches the web, summarizes and builds presentations.
• It analyzes any data source, from Factorial or external, and builds always up-to-date dashboards with Factorial data that can be shared and sent on a schedule.
• It runs any Factorial feature and runs scheduled routines, for example a report every day at nine.

Time and shifts

• It looks for inconsistencies in time tracking and proposes corrections to each employee until they make them.
• Vacation rules are written in plain language and One turns them into a calculation: an extra day on your birthday, days for seniority or hourly proration for part-time staff.
• On-call shifts that don't count as overtime and are calculated correctly in payroll.
• The automatic shift replacement from the first demo.

Talent

• The voice screening of candidates from the second demo.
• Hundreds of ready-made courses validated by Factorial, including one on AI adoption.
• Analysis of hiring processes and of performance with more than 30 signals, such as feedback, incentives and skills.
• Cascading goals, which connect each person's goals with their variable pay in payroll.

Talent and finance

• Headcount planning: each manager proposes who they need next year, with budgets, rules and approvals.
• Salary reviews in cycles, with proposals made by One and calibration processes.

Finance

• Expense policies written in plain language or loaded from a PDF. One checks every expense against the policy and asks a person when needed.
• Purchasing from One, with the purchasing team's approvals and tracking of invoices and deliveries. One looks for anomalies, proposes efficiency improvements and reconciles.
• A new model of Factorial credit cards with cashback, announced for the end of the year.

Payroll

• One explains the payslip to the employee with the information HR chooses to make public: gross and net, deductions, contributions and bonuses.
• A two-way connection with a3innuva, Wolters Kluwer's payroll software, only in Spain.
• Recommendation letters generated from Factorial data.

IT

• One resolves tickets end to end, such as installing an app or fixing a computer, by connecting to the employee's machine.
• It reclaims software licenses nobody uses.
• Inventory of anything handed to employees, such as work clothes, protective equipment or vehicles, with a receipt document.

Where it acts

That's a lot of announcements, and they have something in common. One reads any data source, "internal to Factorial or external", but what it does, it does in Factorial or on the employee's computer.

The only connection to another system they announced is a3innuva, and only in Spain.

Factorial took no questions, so what's missing has to be read in what they didn't show:

• Video calls, calls and messages happen from Factorial. They didn't mention Google Meet or any other tool.
• Nothing about WhatsApp.
• Nothing about reconciling with other vendors' systems.

One does a lot inside Factorial. What happens between Factorial and your other systems is still yours to solve.
