About Yoga

For twelve years Yoga Samsugiharja has worked on growth: planning media for Sunsilk and Indomie, selling AirAsia seats in five countries, then leading Gojek user growth across 16 cities.

Since 2024 he has been building the systems he used to commission from tech teams. That is why every Yogency project is measured in business numbers: leads that close, work hours saved, taxes collected.

How we work

Most of the projects above started as a WhatsApp group and a spreadsheet. The pattern is the same every time.

Read the real data first

Your chats, spreadsheets, and SOPs are read before the first screen is drawn. The problem is usually in there.

Ship small, ship often

Your team uses the first version as soon as possible, and every bit of feedback from the field goes into the next release.

Maintained after launch

Servers, cloud costs, and monitoring are taken care of, so the system keeps running after handover.

Is your process still running on WhatsApp and spreadsheets?

Walk us through it. You will get a system outline and a cost estimate before any commitment.
