SpoolUp

SpoolUp is an aviation marketplace and asset-support platform focused on auxiliary power units (APUs). Built by APU specialists, it helps buyers find available units through structured listings with key details such as model, part number, condition, location, and operating information. SpoolUp says listings are verified and regularly updated, giving users clearer availability and documentation to support faster evaluation and more confident decisions.

The marketplace features APUs in a range of models and conditions. Its OfferUp service provides a structured, open bidding environment for APU cores and material packages, connecting asset owners with aftermarket buyers and supporting competitive demand and price discovery. SpoolUp also provides access to APU stand rentals worldwide for moving units between aircraft, repair shops, and buyers or sellers, with a focus on safe and efficient handling.

For sellers, SpoolUp offers listing support designed to present assets with clear information and documentation, improve exposure to qualified buyers, and reduce evaluation delays.
