Kido Dynamics

Lausanne, Switzerland

KIDO Dynamics is a data intelligence company with a special focus on people mobility. We study the trajectories of people and the digital mobility footprint they leave behind, and use this data to light the way to better decision making. At KIDO we have an unmatched passion for big data, analytics and Social Physics. Since the start we have kept our curiousity and passion, while always being mindful of privacy. By applying Social Physics we turn the huge amounts of anonymised telco data into actionable foot and road traffic mobility insights, enabling you to identify trends, patterns, and outliers — and make smarter and informed decisions. The management theorist, Peter Drucker says “What gets measured gets improved.” Take that step towards Kido, get reliable data and avoid making decisions in the dark.

Frequently asked questions

Updated 23 October 2026

What is Enterprise League?

Enterprise League is a free business directory that helps buyers find the right company by sector and country. Every company has a profile showing what it does, what it offers and how to get in touch.

Is it free to list my company?

Yes, and it stays free: no card, no paid tier. Your profile appears in search results and category pages, can show up to 20 products and services, and lets buyers message you or ask for a quote.

How does verification work, and what does it cost?

Verifying your company is free. Confirm a code we email to an address at your company’s website, or send a company registration document for our team to check, and the verified badge appears on your profile. To show the badge in the directory and search results as well, take out a subscription: the first 14 days are free, and the price is on our pricing page.

Where does the company information come from?

Most profiles are built from public sources, such as official company registers. Claim your company’s profile to correct its details and add your own.

How do I claim or correct my company’s profile?

Open your company’s profile and choose Claim Profile. If you use an email address at your company’s website, a 6-digit code makes the profile yours at once; otherwise our team reviews your request, usually within a few days. Spotted a mistake on a company that isn’t yours? Tell us through our contact page.
