## About

Blackline Inc. was founded in San Francisco in 2017 by Shannon Almeida, a former vice president at Volition Capital, where she focused on growth-stage software investing. The firm emerged from Almeida's conviction that early-stage B2B software — particularly infrastructure and automation tools — was undercapitalized by generalist seed funds. She established Blackline as a sector-focused vehicle that could lead rounds and take board seats, differentiating from the party-round dynamics common in Bay Area pre-seed syndicates. The strategy centers on Seed and Series A enterprise software companies, with selective participation in Series B follow-ons. Blackline targets capital-efficient businesses building data infrastructure, API platforms, DevOps tooling, and applied AI. Confirmed portfolio positions include Hex Technologies, the collaborative data workspace (per TechCrunch, 2021), and Streamlit before its acquisition by Snowflake. The firm also holds exposure to healthcare workflow automation and fintech infrastructure, with a geographic focus on US-based companies, though it has evaluated opportunities in Toronto, Vancouver, and London. Almeida structures investments as direct equity with pro-rata rights and typically reserves 50% of fund capital for follow-on deployment. Blackline operates with a lean team from a single office in San Francisco. The firm does not publicly disclose assets under management. March 2024: Led a $5.2 million seed extension for a developer-tools startup focused on codebase visualization (per public filing). The firm maintains no adjacent vehicles, philanthropic foundations, or operating companies. Blackline's structural differentiator is its single-GP architecture with deep sector concentration. Unlike multi-partner early-stage firms that diversify across sectors for partner bandwidth, Almeida runs a narrow thesis — enterprise infrastructure and developer tools — which creates a repeatable pattern-recognition advantage. Without a wealth-origin backer or institutional anchor LP, the firm's continuation depends on Almeida's ability to convert board seats into board-level outcomes, a governance model where GP succession is unresolved but the concentrated portfolio makes every position matter.
