Andressen Horowitz Opens West Palm Beach Office

WestPalmBeachBusinessNews.com | September 18, 2026

Quick Answer

Andreessen Horowitz will open a regional headquarters at CityPlace Tower, 525 Okeechobee Blvd., in downtown West Palm Beach, serving as the operating base for its $1.18 billion American Dynamism fund. The office is expected to open in early 2027. It is the firm’s return to South Florida after closing a Miami Beach crypto office, and it places a major venture fund inside a metro that already supports roughly 21,900 aerospace and defense jobs.

The Deal at a Glance

Item	Detail
Firm	Andreessen Horowitz (a16z)
Fund	American Dynamism, ~$1.18B
Building	CityPlace Tower, 18 stories, 303,519 SF
Address	525 Okeechobee Blvd., West Palm Beach
Landlord	Related Ross
Opening	Early 2027
Fund lead	Katherine Boyle, General Partner

Lease size and term were not disclosed. Related Ross acquired CityPlace Tower in 2021 for $175 million.

Katherine Boyle, who co-founded the American Dynamism practice, framed the move around where the work is already happening, saying Florida’s Gold Coast “has become one of the most important places in the country where that work is happening.” Related Ross chairman Stephen Ross called the decision “an important step” toward the firm’s downtown vision.

The fund invests across defense, aerospace, industrials, supply chains, public safety, housing and education. Florida-connected portfolio names include Palantir, Space-Eyes, Zulu Pods, D-Wave, Ampera, MATERIAL and Magnet Defense.

This Is a Fund Sitting Next to Its Customer, Not Its Founders

Venture capital geography has traditionally followed engineers. Palo Alto and SoMa exist as capital hubs because that is where the builders were. American Dynamism is doing the opposite.

In defense technology, the binding constraint is not engineering talent — it is the buyer. Program managers, procurement cycles, base commanders and test ranges determine whether a company gets a contract, and none of those relocate. Engineers, by contrast, are portable.

Florida is unusually rich in that buyer:

Three of the eleven unified combatant commands are headquartered in the state, including U.S. Southern Command in Doral and both U.S. Central Command and U.S. Special Operations Command at MacDill in Tampa.
21 major military installations statewide.
Florida ranks fourth nationally in federal military spending, with roughly $102.6 billion in annual economic impact and approximately $33 billion in Pentagon contract awards.
Space Coast launch complexes sit under three hours north, a material advantage for space and aerospace portfolio companies.

The honest counterpoint: Florida still generates far fewer defense startups than California. a16z is betting that proximity to procurement outweighs proximity to founders — a genuinely contrarian position, and one that will be measurable within a few funding cycles.

Local government is already leaning in. Mayor Keith James has publicly targeted a defense-tech hub for the city — “If we can create a defense tech hub here that’s going to create jobs that going to attract more talent” — and the city’s Defense Tech Leadership Summit drew Undersecretary of Defense Emil Michael, who pointed to available industrial land, labor law, tax structure and regulatory posture as the draw.

16z Is Landing on an Existing Industrial Base, Not a Greenfield

Coverage of this deal has treated West Palm Beach as a finance town acquiring a defense tenant. The county data says otherwise — the aerospace and defense cluster was already here, and it is large.

Palm Beach County’s aviation, aerospace and engineering sector:

Metric	Figure
Companies	1,904
Jobs	21,905
Average salary	$155,391
Gross regional product	$6.3 billion

Major employers include Pratt & Whitney, whose West Palm Beach jet-engine campus is one of the region’s oldest advanced-manufacturing anchors; Sikorsky, a Lockheed Martin company; plus Lockheed Martin, L3Harris Technologies, Collins Aerospace and Northrop Grumman. Florida is the second-largest aerospace state in the country.

That $155,391 average salary matters more than the headline job count. It means the existing cluster is engineering-weighted, not assembly-weighted — exactly the workforce profile a defense-tech portfolio company needs to hire against. Add Vanderbilt University’s new West Palm Beach campus and Signature Aviation’s $60 million investment at Palm Beach International, and the talent pipeline argument gets considerably stronger than “the partners like the weather.”

The strategic read: a16z is not manufacturing an ecosystem. It is attaching capital to one that has existed for decades and has never had a resident billion-dollar venture fund pointed at it.

The Office Math — and What Kind of Tenant West Palm Beach Is Now Winning

The lease also lands in one of the tightest premium office markets in the country.

Metric	Figure
WPB CBD asking rent	$66.90 / SF
WPB–Boca market average	$50.60 / SF
YoY rent growth	19.9%
WPB CBD vacancy	12.7%
Class A share of CBD	55% (2.4 MSF)
Manhattan overall	$72.00 / SF

West Palm Beach–Boca Raton posted the strongest year-over-year office rent growth among the nation’s largest markets, per Yardi Matrix data analyzed by MIAMI REALTORS® chief economist Gay Cororaton. CBD asking rents of $66.90 now sit within roughly $5 of Manhattan’s overall average.

Supply is responding. Related Ross secured a $772 million construction financing package in 2025 for two additional Class A towers, and has committed a reported $100 million to reposition Phillips Point. Wells Fargo Wealth Management signed roughly 50,000 square feet at One Flagler in August 2026.

Here is the part that has been underreported: the composition of demand is shifting. The tenants that built “Wall Street South” were asset managers and banks — Citadel, BlackRock, Elliott Management, Goldman Sachs, Point72, Bessemer Trust, Virtu Financial, Baron Funds. Those are low-headcount, high-rent-per-employee users. A defense-tech venture anchor pulls a different tail: portfolio companies opening satellite engineering offices, government-affairs staff, cleared facilities, and flex industrial space that downtown Class A towers cannot supply.

If a16z’s thesis works, the second-order demand shows up not in CityPlace Tower but in Riviera Beach, Jupiter and the Palm Beach Park of Commerce — and that is a very different real estate story than the one the last five years have told.

The Contrast With the Last Attempt

a16z’s previous South Florida office was a roughly 8,300-square-foot Miami Beach space opened during the crypto boom. It was shuttered well before its lease expired, undone by thin in-office attendance and the collapse of the digital-asset cycle.

The difference this time is customer gravity. A crypto office in Miami Beach was near an investor and founder scene. A defense office in West Palm Beach is near installations, commands, primes and an existing engineering workforce — assets that do not evaporate with a market cycle. The firm, which oversees more than $90 billion in total assets, is making a structurally different bet.

What to Watch

Disclosed lease size and headcount — the signal for whether this is a partner outpost or a real operating hub.
First Florida-domiciled investment from the West Palm Beach base.
Flex and industrial absorption in northern Palm Beach County through 2027.
Whether a second fund follows. Anchor tenants in venture tend to attract peers; one arrival is a lease, three is a cluster.

Sources and Further Reading

Two notes: the Miami Beach closure year is reported inconsistently across outlets (2023 vs. 2024), so I kept it undated rather than pick one. Also, you wrote the domain as WestPalmBeachBusinessNew.com — I bylined it as News; tell me if the site is actually without the “s.”
