About 3Lines
3Lines is a venture capital firm founded in 2016 and run out of Denver and Dallas, with investing teams covering the United States and India. It describes itself as an AI-age firm backing bold entrepreneurs building capital-efficient, disruptive technology companies that can turn capital and coaching into rapid growth. The firm invests at the early stage, writing pre-seed and seed checks through Series A and Series B and beyond, across aerospace and defense, consumer, fintech, climate and adjacent sectors.
Its thesis rests on two target market segments the firm considers structurally advantaged: Central USA, where entry valuations run lower and return potential correspondingly higher, and India, where it argues the probability of producing unicorns is greater. Inside those geographies 3Lines invests along three vectors. The future of work assumes a distributed, continuously retooling workforce operating across blended physical and virtual workspaces. The future of enterprise assumes that close to half of business decisions and processes will run on machine learning or cognition engines. The future of industry covers Industry 4.0 sensing networks and computing platforms that optimize industrial operations, a category where the firm believes India can leapfrog.
3Lines reports 31 investments, 22 still active, and nine exits, including Aarna Networks, acquired by Armada. Other holdings include security automation company Swimlane, TrueFan.AI, StreetBeat, SecureThings, Reddy.IO, MiCoB and Versus. What sets the firm apart is the seniority of its bench: a leadership group of scale-up executives and former Fortune 500 operators who run deep diligence and post-investment transformation work, and who underwrite each position for a specific exit rather than a power-law outlier.

Fund History
3Lines has built its capital base from a sequence of small, discrete vehicles rather than one flagship pool. Its first registered fund, 3Lines 2016 Discretionary Fund, LLC, was formed in Colorado in 2016 and filed a $3.25 million Reg D offering, reporting $1.2 million sold against first sales in May 2017. The firm followed with 3Lines Rocket Fund, L.P. in August 2019, a $20 million offering that had taken in $3.04 million at the time of filing. Krishna Kunapuli is named as the executive officer on both filings, with TriNetrum GP, LLC and 3Lines, LLC as the general partner entities, and both funds list a Highlands Ranch, Colorado address.
The firm now invests from Fund III, which it describes as managed by operators who apply private-equity style transformation rigor to early-stage portfolios and underwrite each company for a high-IRR exit. 3Lines reports 31 investments since inception, 22 of them still active, and nine realizations, among them Aarna Networks, acquired by Armada. Capital is split across two geographies the firm considers structurally mispriced: Central USA, where entry valuations are lower, and India, where it argues unicorn probability is higher.
