Lainy backs software and marketplaces that modernize complex vertical workflows. Her cases favor founder-market fit, a painful operational wedge, simple products built on technically difficult systems, and distribution that compounds through workflow adoption or network effects. Across logistics, work management, healthcare, labor, and creative tools, she looks for products that turn fragmented manual activity into an integrated platform and make a professional capability accessible to more users.
Start with the specific vertical workflow, its frequency, current labor and software cost, and why existing systems fail. Show founder-market fit, customer references, time-to-value, retention, expansion, bottom-up or marketplace distribution, and the data or network advantage created by usage. Explain the first wedge and the credible path to a broader system of record, transaction layer, or category platform.
Founders with direct industry knowledge, products that solve a frequent and expensive workflow, enthusiastic reference customers, an initial wedge that can expand across a vertical, viral or bottom-up distribution, and technology that materially increases speed, flexibility, or access. She also values simple user experiences supported by deep purpose-built engineering.
No explicit personal pass list is public. Her investments imply weaker fit for horizontal tools without a sharp user or vertical, AI features with no workflow ownership, products that automate low-value tasks without expansion potential, marketplaces lacking liquidity or trust advantages, and teams without direct understanding of incumbent systems and customer behavior.
Find a frequent manual workflow near the top of a vertical's operating funnel, validate acute pain and reference enthusiasm, then map how integrations, data, and adjacent tasks turn the wedge into a comprehensive platform.
Measure whether an individual user receives immediate value, collaboration exposes the product to adjacent users, usage spreads across teams, and the accumulated workflow context supports organization-wide adoption.
