The 50 most recent funded rounds in Arlington span two distinct metros — Arlington, Virginia and Arlington, Texas — with Virginia entries comprising the clear majority. Disclosed round sizes cover an unusually wide range: from $20K raises (BILLIONS, Phalanx) up to IntraFi's $2.0B close in August 2025, the largest single round in the dataset. Energy is the highest-capital sector overall, with Earthrise Energy ($630M, June 2025), U.S. Energy Development ($165M, February 2025), and Lightshift Energy ($40M, July 2025) together accounting for a substantial share of aggregate disclosed capital.
Artificial intelligence cuts across sectors — agriculture, aerospace, fintech, and governance — appearing in more than a dozen entries. The government and defense cluster is notable: Twenty Technologies ($38M Series A, cybersecurity) and Rune Technologies ($24M Series A, military) both closed in 2025, reflecting Arlington, Virginia's proximity to federal contracting activity. Round velocity picked up in the latter half of 2025, with five closes recorded between September and November alone.

Frequently asked
What are the largest disclosed rounds among the 50 most recent Arlington fundings?
IntraFi leads at $2.0B (August 2025, financial services), followed by Earthrise Energy at $630M (June 2025, energy), U.S. Energy Development at $165M (February 2025, energy), PerformYard at $95M (January 2024, software), and GridPoint at $45M (March 2025, data and analytics). Energy and financial services account for four of the five largest raises shown.
Does this page cover only Arlington, Virginia, or multiple cities named Arlington?
Both Arlington, Virginia and Arlington, Texas appear in the dataset. The Virginia entries are the large majority; Texas-based companies include U.S. Energy Development ($165M), LIVV Audio ($1M Seed), and Blush + Whisk (undisclosed amount).
How active is the AI sector in recent Arlington funding rounds?
Artificial intelligence is tagged across more than a dozen entries, including Interos ($40M), Echelon AI ($5M Seed, aerospace and drones), Helios Artificial Intelligence ($5M Seed, agriculture analytics), Trustible ($5M Seed, AI governance), and GreenLyne ($8M, fintech and regtech). Several AI-tagged companies—NOVI, DeepSig, Fifty One Ai—have undisclosed amounts, so aggregate AI capital from this set is a floor, not a ceiling.
What round stages are most common across the 50 rows?
'Series Unknown' and 'Venture – Series Unknown' are the most frequent designations. Named stages include six Series A rounds (Twenty Technologies, Rune Technologies, Nooks, Grey Market Labs, Fixify, GoTab), three Series B rounds (Cape, The Rounds, Stacklet), and eleven Seed rounds.
How significant is government and defense-related funding in this set?
Two companies explicitly list government or military as a primary sector: Twenty Technologies, which closed a $38M Series A in November 2025 in cybersecurity and government, and Rune Technologies, which raised $24M in a Series A in July 2025 focused on government and military. Both are Arlington, Virginia-based, consistent with the area's federal contracting ecosystem.

Information technology companies collectively account for substantial disclosed volume: Nooks ($25M Series A), Fixify ($25M Series A), Cape ($15M Series B), and Stacklet ($15M Series B) total $80M in named rounds.
