David Wieland had three successful companies in hotel connectivity, structured interviewing, and digital media before becoming a full-time investor, and he tends to build around unglamorous but necessary problems rather than chasing trends. He also co-founded and chaired IrishAngels, a Notre Dame-connected angel investing network, and brings 15 years of seed-stage investing experience along with a B2B SaaS background, giving him a view of fintech as something woven into many kinds of businesses rather than a category on its own.
