Stefan Walter co-founded NAP after founding his own company, bringing firsthand operator experience to his work with early-stage founders, and studied finance, tax law, and international corporate law to help founders specifically with funding strategy, financial modeling, and investor communications. He invests in expert founders solving hard problems in enterprise tech, focusing on companies with proprietary data, instant customer utility, and strong system interoperability, while emphasizing practical support on non-glamorous topics like follow-on fundraising and international expansion.
