Sponsor
The entity that forms the SPAC, funds its costs, and holds the founder shares that pay off only if a deal closes.
Also written: sponsor entity, founder
The sponsor is usually a limited liability company created for the single deal, standing behind which is a management team, a private equity firm, or a family office. It buys the founder shares before the IPO for a nominal amount and covers the costs of getting the vehicle to market.
Sponsor vehicles are named per deal, which is why the entity on a prospectus tells you about one SPAC rather than about the house behind it. Grouping them into a franchise is what makes a track record visible.
Why it matters
The sponsor's economics are asymmetric: the founder stake is worth a great deal if a combination closes and nothing at all if the trust is returned. That asymmetry is the single strongest force acting on a SPAC as its deadline approaches.
