Eleven people.
One pager.

Plinth is eleven engineers and designers in Porto and Rotterdam. Since 2015 we have designed, built and hosted the web for teams who plan in years. No account managers, no handoffs, no rot: the people who pour your product are the ones carrying the pager when it ships.

“They rebuilt our platform, then refused to let it break. Three years in — zero 3 a.m. calls.”

— Marta Ferro, CTO, Cartload
