# Rising Tide Partners > Rising Tide Partners (RTP) is a network-native, early-stage venture fund based in San Diego, California. Founded and led by Managing Partner Neal Bloom, RTP invests earliest where its access runs deepest — connecting exceptional founders with the people, customers, and capital that change company trajectories. Its thesis: access is the unfair advantage. RTP invests in hardtech, defense, AI infrastructure, maritime, autonomy, advanced manufacturing, med device & diagnostics, ag & food, and gaming & consumer. It leads or co-leads pre-seed and seed rounds, concentrating into winners. The fund is built on a 13-year track record of investing through Interlock Capital and personal angel deals, and is backed by an operator-LP network of 500+ founders, operators, and domain experts. RTP also runs RTP Communities — a membership network of founders, investors, and operators in San Diego — produces a four-show podcast network under the Rising Tide Partners banner, and publishes the annual San Diego Hardtech 50. ## Core Pages - [Home](https://risingtidepartners.co/index.html): The fund thesis, the nine-company flagship fleet, and the Access Engine that connects them. - [Portfolio](https://risingtidepartners.co/rtp-portfolio-fleet.html): The nine RTP companies in full, plus the complete register of prior investments through Interlock Capital and angel deals. - [Communities](https://risingtidepartners.co/rtp-communities-fleet.html): RTP Communities — founder dinners, build days, hikes, and investor office hours across six industry tracks.
