# January Ventures
January Ventures is a pre-seed venture capital firm that backs outlier founders building B2B software startups that digitally transform traditional industries. Its mission is to “rewrite the networks in venture” by investing in ambitious, tenacious founders—especially those from underrepresented backgrounds—who may lack elite pedigrees or Silicon Valley connections but possess deep domain expertise and outsized ambition.
The firm focuses on early-stage, category-defining B2B startups in sectors like fintech, healthtech, climate and sustainability, enterprise software, AI/ML, and future-of-work platforms. January Ventures is known not just for its capital but for its hands-on, empathetic operating support and its unusually strong, diverse founder community. By structurally replacing the traditional friends-and-family round with cold outreach and a founder-first ethos, it has carved out a distinct role in the startup ecosystem as a highly supportive, accessible, and inclusive early-stage partner.
January Ventures was founded in 2018 by Maren Bannon and Jennifer Keiser Neundorfer, both operator-turned-investor partners with deep experience in tech and startups. Maren Bannon, with a background in marketing and product roles at companies like Genentech and Roche, brings a strong operational lens to B2B and healthtech startups. Jennifer Keiser Neundorfer, a Harvard- and Stanford-educated operator and investor, previously co-founded Flashstarts, a startup accelerator focused on software startups outside Silicon Valley, which shaped her belief in backing exceptional founders regardless of geography or network.
The firm emerged from a conviction that the traditional venture model systematically overlooks talented founders simply because they don’t fit the “standard” mold. January Ventures was designed to fix that by creating a more open, meritocratic entry point into venture capital, particularly for female, immigrant, and underrepresented founders. Over time, it has evolved into a pre-seed specialist with a strong track record of backing breakout companies and building a tight-knit, high-caliber founder community across the U.S. and Europe.
January Ventures is riding several powerful trends reshaping venture capital and startup creation:
By backing outlier founders early and building a supportive, inclusive ecosystem around them, January Ventures is helping to redefine what a modern, equitable, and high-impact venture firm looks like.
January Ventures is well-positioned to deepen its role as a leading pre-seed partner for outlier B2B founders, especially as the venture landscape continues to prioritize diversity, founder support, and early-stage specialization. With a strong Fund II closed in 2022 and a new fund reportedly in market as of early 2025, the firm is likely expanding its capacity to back more companies and increase follow-on support.
Looking ahead, several trends will shape its trajectory:
In a world where access to capital and networks remains uneven, January Ventures stands out by betting on founders, not resumes. Its future isn’t just about returns—it’s about redefining who gets to build the next generation of iconic companies.
January Ventures has more than 26 tracked investments across 25 companies. The latest tracked deal is $6.0M Seed in Flock AI in February 2026.
