An education company from Peru

Live education, on our own technology

We are Danke Peru E.I.R.L. Through our academy, Números al Alcance, we teach live math classes every weekday to primary and secondary school students and to those preparing for university. From what we learn in every class we build Sala Danke, Pizarra Danke and Cuenta Danke: the technology to teach well online, even to students on a phone.

Our academy in numbers

  • 4,290 students have attended at least one of our classes since January 2025.
  • 179,000 attendance records and counting: one per student per live class.
  • 60 live classes a week, all on Sala Danke since September 28, 2026.
  • 660 math topics in an open library, free and with no sign-up.

Measured on October 16, 2026, in the systems of the academy and of Sala Danke.

Our products

Built by us and used every day in the academy's classes. They run in the browser of any phone, tablet or computer, with nothing to install.

Sala Danke

Video classes and meetings, with the order of a classroom.

In a class, a teacher does more than talk and share a screen. They need to manage who participates, know who attended, and make sure the explanation comes through on any connection. Sala Danke is built for that.

  • The floor, one at a time. The teacher gives the floor and the room enforces it; everyone else raises a hand and waits their turn, in order.
  • Attendance that takes itself. When each student joined, how long they stayed connected and whether they were late, with no roll call.
  • Every student, identified. Students join with the account their institution gives them, and the institution decides who can enter.
  • A sharp board on a weak signal. What the teacher writes on Pizarra Danke reaches each student as strokes, not video, so formulas stay legible even on a poor connection.
  • Recorded classes. Any class can be recorded to watch again.
  • Accessible. It works with a keyboard and a screen reader.

In daily use. Since September 28, 2026, every class on the academy's timetable is taught on Sala Danke: about 60 a week, with up to 78 people in a single class.

Pizarra Danke

The whiteboard to teach and present live.

A digital whiteboard with its own ink engine and more than 50 tools. Built to teach math, and useful for any subject.

  • Ink that feels real. Pressure, smoothing and stroke prediction, with a pen, ballpoint or brush.
  • Real math. Write a formula and it is graphed on the Cartesian plane.
  • Instruments on the page. Ruler, protractor, set squares and compass, plus 3D solids you can rotate, unfold and slice.
  • Pieces you can move. Matchsticks, coins, dice, dominoes, balance scales and jugs, to reason with in class.
  • It saves itself. Each page is saved as you write, on your device and on the server.
  • Private by design. No ads and no tracking: each page is visible only to the accounts you authorize.

In daily use. The academy's teachers write between 1,600 and 2,000 class pages a week, and more than 27,000 since June 2026.

Cuenta Danke and Consola Danke

One account, and the console to manage it.

Each person signs in to our products with a single account, Cuenta Danke, and each institution manages its people from its admin console, Consola Danke.

  • One account. Built on the OpenID Connect open standard. Today, Sala Danke and the academy's system sign in through it.
  • Each institution's people. The institution creates its people's accounts and organizes them into organizational units.
  • Each product, on or off. The institution decides which products its people use.
  • Two-step verification. The institution can require it for any of its accounts, and administrators always sign in with it.
  • Its own domain. The institution verifies its domain, and its accounts use its own addresses.
  • Care for minors. Products only learn whether a person is a minor or an adult, never their date of birth.

In production since September 26, 2026. The academy's staff and students have signed in with it since September 28.

Born teaching

Números al Alcance is Danke's math academy, and our first customer.

Since 2024 it has taught 90-minute live classes, Monday to Friday, to students from fifth grade of primary school to the last year of secondary school and to those preparing for university, with monthly fees from 30 Peruvian soles (about 9 US dollars). Students can rewatch recorded classes, and they have their own materials, self-assessments and attendance report.

The academy uses our products the way any institution would: through the same Console and under the same rules. So every improvement is tested first in real classes, with real students.

And it keeps a free, open library of 660 math topics for primary, secondary and pre-university students, with no sign-up.

A class is not a meeting

Video calls work very well for meetings. After thousands of online classes we learned that a class needs more: managing participation, knowing who attended and for how long, identifying each student, and explaining step by step on a board that reads well on a phone. We decided to stop working around it and build it.

  • Built for real connections

    Many students join from a phone on mobile data. That is why the board travels as strokes rather than video, and what is written stays sharp.

  • We look after students

    Most of our students are minors. Each one joins identified by their institution, and our products carry no ads and sell no data.

  • Accessible to everyone

    They work with a keyboard and a screen reader, with good contrast, on screens of any size.

  • Our own technology

    The video, the whiteboard and the identity service are ours, running on servers we manage in South America, close to the people who use them.

We build with Claude

We are a small team with a high bar.

We design, write, test, review for security and operate all of our software with Claude Code by Anthropic: Cuenta Danke, Sala Danke, Pizarra Danke and the academy's management system, including their cloud infrastructure and deployments.

And we are bringing Claude into our products. The first step is already live: an assistant for the team that answers the academy's families, currently in a supervised pilot.
