About
Architecture discipline, product-team speed
fello.work brings enterprise-grade architecture discipline and the speed of a product team that ships its own software.
The company
We design systems, then we build them
fello.work is a solution architecture and engineering consultancy based in Bengaluru, working with clients in India and internationally. We design AI platforms, applications, mobile apps and the backends behind them, and then we build them, from the first diagram to production.
We also build and run our own product, Fello, a business suite for Indian SMBs. The architecture advice we give is the kind we follow ourselves.
fello.work is a trade name of Yali Infoventures Private Limited.
The name
fello, as in fellow
A fellow is someone who works alongside you. That is the relationship we want with clients: a partner who shares the problem, not a vendor who takes a specification and disappears.
The logo says the same thing. It is a circuit trace: filled nodes are the work we do, and open nodes are the connections to your systems.
