## Questions

### What investment stages does RockPort Capital Partners target?

RockPort describes itself as a multi-stage venture capital firm. Its mandate spans early-stage seed and startup rounds through expansion and late-stage venture, applied exclusively within its stated sectors of alternative energy, mobility, and sustainability. This structure allows it to support a company from prototype through commercial scaling, though specific fund-vintage stage concentrations are not publicly detailed.

### Which sectors does RockPort Capital Partners focus on?

The firm’s investment remit covers three interconnected domains: alternative energy, mobility, and sustainability. Within this triad, its website references both industrial and consumer-facing companies whose technologies provide new solutions to large worldwide markets — a framing that encompasses power generation, grid infrastructure, transportation systems, and resource-efficiency applications.

### Is RockPort Capital Partners a generalist venture firm or a dedicated sector fund?

RockPort is a dedicated sector fund. Unlike generalist venture platforms that layer on a cleantech practice opportunistically, RockPort structured its entire investment operation around energy, mobility, and sustainability. This thesis lock-in means it does not pursue software-only, consumer internet, or healthcare bets outside of an energy-transition or resource-efficiency nexus.
