"I love working at Tinybots because we get so many messages about happy clients, reminding us that we’re improving the lives of real people. Apart from that it’s a motivated and social team that I’m glad to be a part of. Our online Christmas meeting was a lot of fun with each team member organizing a small activity, this ranged from a pub quiz to an interrogation by a hostile Tessa robot deciding whether to eliminate humankind or not."

How are your colleagues Max?
Our AI developer Arno is one of the most structured software architects on the planet. Ensuring that the scope of the project is clear from the start. Sometimes it seems he can program in his sleep and in between you can have some interesting conversations with him about Taiwanese geopolitics, video games and whether you should pick up a toxic octopus.

Our founder Wang is always busy but never fails to make time when you need him. It's great to discuss new features together with Wang as he always helps you stay sharp to end up with the best possible solution. It's always nice to have a beer or a coffee with Wang, and with his passion and calm he keeps the team motivated and focused.
