Venture funding for AI companies in the Miami area kept climbing in 2025. Refresh Miami, summarizing the eMerge Americas Insights report, said AI-focused startups in the Miami metro raised $1.23 billion in venture capital in 2025, up from $897 million in 2024.
Miami now has a group of AI-native companies large enough to track by hiring, not only by funding announcements. Several of them were founded elsewhere, including in Israel, and chose Miami as their U.S. headquarters. This post is part of Landbase's wider look at AI startups adding headcount fastest.
This list ranks venture-backed AI startups headquartered in Miami-Dade and Broward counties by 12-month headcount growth measured in Landbase data, then verifies each company's funding and operating evidence against public sources.
How the companies were selected
The starting pool was companies with 30 or more employees headquartered in Miami, Miami Beach, Fort Lauderdale, or nearby cities in Miami-Dade and Broward counties, founded in 2019 or later.
Every company on the list had to meet four criteria:
- Headquartered in the Miami area, confirmed by press coverage or company materials, which excludes companies with only a sales office in South Florida
- AI-native, meaning the core product is built around AI rather than adding it as a minor feature
- Venture-backed, with at least one disclosed institutional round
- Positive 12-month headcount growth in Landbase data, used as the ranking order
Headcount growth is calculated from professional-profile data and can differ from company-reported figures. Funding, valuation, and revenue figures below come from company announcements and press coverage rather than headcount data. Funding alone does not establish growth, so it is treated as one of several company buying signals.
1) Flamingo
Founder: Michael Assraf
Latest round: $4.5 million seed, September 2026
12-month headcount growth: +200%
Category: AI IT operations platform for MSPs
What Flamingo builds
Flamingo is building OpenFrame, an open-source, AI-driven platform for managed service providers (MSPs). It puts remote monitoring and management, device management, monitoring, and ticketing into one data model, then adds AI agents to handle repetitive IT and security tasks.
Latest growth evidence
The company said 400 MSPs had tested OpenFrame across 10,000 endpoints, with another 2,500 providers on a waitlist. Flamingo had about 35 employees when it announced its seed round, and Assraf said he planned to hire at least 10 people in Miami, mostly in sales, marketing, and customer-facing roles.
Recent funding
Vertex Ventures led the $4.5 million seed round. It followed a $2.2 million pre-seed in October 2025, for total funding of $6.7 million.
Why it matters
Flamingo is the earliest-stage company on the list.
2) OpenEvidence
CEO: Daniel Nadler
Latest round: $250 million Series D, January 2026
12-month headcount growth: +180%
Category: Clinical AI and medical information
What OpenEvidence builds
OpenEvidence provides an AI medical information platform that answers clinical questions for physicians using peer-reviewed literature, including content from partners such as the New England Journal of Medicine and JAMA. It is free for verified clinicians and funded by advertising.
Latest growth evidence
The company reported about 18 million clinical consultations in December 2025, up from about 3 million per month a year earlier. It was reported to be used across more than 10,000 U.S. hospitals and care centers, with an annualized revenue run rate of about $100 million, when it raised its Series D at a $12 billion valuation.
Recent funding
Thrive Capital and DST Global led the Series D, bringing total funding to roughly $700 million. Later reports of talks at higher valuations have not been confirmed by the company.
Why it matters
OpenEvidence is the largest AI company headquartered in Miami by funding and valuation, and its rounds account for a large share of the region's AI venture totals.
3) Hydra Host
CEO: Aaron Ginn
Latest round: $100 million Series A, June 2026
12-month headcount growth: +134%
Category: GPU infrastructure software
What Hydra Host builds
Hydra Host does not own GPUs. Its Brokkr software lets data center operators provision, manage, and rent out GPU capacity to AI companies, so that idle capacity can be sold to inference platforms, GPU marketplaces, and model developers.
Latest growth evidence
The company said its network spans more than 50 data centers across the Americas, Asia-Pacific, and EMEA. In its Series A announcement, it said a majority of major inference platforms, along with many GPU marketplaces and frontier labs, rely on Hydra Host.
Recent funding
Kindred Ventures led the $100 million Series A, with NVIDIA, ARK Invest, Comcast Ventures, Magnetar, and PEAK6 participating. Refresh Miami reported a valuation near $800 million.
Why it matters
Hydra Host is Miami's clearest AI infrastructure company.
4) Boom
CEO: Shahar Goldboim
Latest round: $12.7 million Series A, October 2025
12-month headcount growth: +100%
Category: AI property management for hospitality
What Boom builds
Boom describes itself as an AI-powered property management system for short-term rental and hospitality operators. It automates guest messaging, operations, and owner reporting in one platform.
Latest growth evidence
Boom said its platform was used by hospitality businesses in 20 countries and that its AI handles up to 80% of guest messages and inquiries. Goldboim previously ran DesignedVR, a luxury vacation rental company, and Boom raised its Series A to fund international expansion and engineering, data science, and customer success hires.
Recent funding
Avenue Growth Partners led the $12.7 million Series A.
Why it matters
Boom applies AI agents to hospitality operations, a large local industry in South Florida.
5) Erudit
CEO: Alejandro Martinez Agenjo
Latest round: $10 million Series A, September 2023
12-month headcount growth: +88%
Category: AI workforce analytics
What Erudit builds
Erudit provides AI software for HR teams that measures employee experience indicators such as burnout risk and engagement.
Latest growth evidence
At the time of its Series A, Erudit reported working with more than 15 Fortune 500 companies and firms valued at more than $1 billion. It also said revenue grew 310% between the second quarter of 2022 and the second quarter of 2023.
Recent funding
Conexo Ventures, Athos Capital, Ignia Partners, True Blue Partners, and Fondo Bolsa Social led the $10 million Series A. Refresh Miami reported total funding of $12 million including that round. No newer round has been announced.
Why it matters
Erudit is one of the older AI companies on the list. Its public operating figures date from 2023, so its headcount growth is the most recent available indicator of momentum.
6) Togal.AI
CEO: Patrick Murphy
Latest round: Seed round, March 2023
12-month headcount growth: +84%
Category: AI construction estimating
What Togal.AI builds
Togal.AI provides cloud-based pre-construction software that uses AI to detect, measure, and label spaces and features in construction plans.
Latest growth evidence
Togal.AI reported that annual recurring revenue grew more than 1,000% from January 2024 through December 2025, after 940% growth in 2023. The company also said it planned to add 100 employees in 2026.
Recent funding
Funding trackers list a seed round in March 2023 with investors including Florida Funders, Coastal Construction Company, and Lightning Capital. Reported totals range from about $5 million to $7 million. No newer round has been announced.
Why it matters
Togal.AI is hiring on reported revenue growth rather than a large recent round, which is unusual among the companies on this list.
7) Gail
Co-founders: Matthew Vega-Sanz and Michael Vega-Sanz
Latest round: $8.2 million seed, May 2025
12-month headcount growth: +48%
Category: AI agents for financial services
What Gail builds
Gail builds AI agents that automate calls, text messages, chat, and workflows for insurers, banks, and lenders.
Latest growth evidence
When it announced its seed round, Gail said its AI agent product was live with more than 200 companies and handled nearly 5 million phone calls a day for large banks and insurers. It had about 15 engineers then, working from an office in Coral Gables.
Recent funding
HTwenty and Act One Ventures co-led the $8.2 million seed, with Mangusta Capital, NextView Ventures, and A15 participating.
Why it matters
Gail's founders sold the insurtech startup Lula in 2024 and stayed in Miami to build their second company.
8) Pillar Security
CEO: Dor Sarig
Latest round: $9 million seed, April 2025
12-month headcount growth: +43%
Category: AI agent security
What Pillar Security builds

Latest growth evidence
When it announced its seed round, Pillar said it planned to triple its workforce from 10 to 30 employees by the end of 2025, and named customers including Similarweb, Eleos Health, and AvidXchange. In December 2025 it launched RedGraph, a product that maps attack surfaces for AI agents.
Recent funding
Shield Capital led the $9 million seed, with Golden Ventures and Ground Up Ventures participating.
Why it matters
Pillar follows a common Miami model: an Israeli-founded security company with research and development in Tel Aviv and its U.S. headquarters in Miami.
9) FirmPilot
CEO: Jake Soffer
Latest round: $22 million Series A-1, February 2026
12-month headcount growth: +29%
Category: AI marketing for law firms
What FirmPilot builds
FirmPilot provides an AI marketing engine for law firms that covers SEO and generative engine optimization, paid search, local SEO, digital PR, social media, and website optimization.
Latest growth evidence
FirmPilot said it had generated tens of thousands of qualified leads for law firms since its 2023 founding, and that clients reported case volume increases of more than 180%. The company closed an oversubscribed $22 million Series A-1 less than two years after its first Series A.
Recent funding
DeepWork Capital led the Series A-1, with Data Point Capital, Blumberg Capital, and Thomson Reuters Ventures participating. Total funding is $27.25 million.
Why it matters
FirmPilot sells into legal marketing budgets, a different buyer from the legal AI tools that law firms use for practice work.
10) Guardz
CEO: Dor Eisner
Latest round: $56 million Series B, June 2025
12-month headcount growth: +18%
Category: AI-powered cybersecurity for MSPs
What Guardz builds
Guardz provides a security platform for MSPs that protect small businesses. It brings identity, email, endpoint, cloud, and data protection into one engine, and adds AI-powered automation to its 24/7 managed detection and response service.
Latest growth evidence
Guardz said its total funding had reached $84 million in just over two years. Lead investor ClearSky cited the company's rapid growth when Guardz raised its Series B. Part of the funding is for its Miami office.
Recent funding
ClearSky, a West Palm Beach venture firm, led the $56 million Series B, with Phoenix Financial, SentinelOne, Glilot Capital Partners, and Lumir participating.
Why it matters
Guardz and Flamingo both sell to MSPs from Miami. That gives the city a small group of companies building AI tools for the channel that serves small business IT.
What the Miami AI startup market shows
Several patterns stand out.
First, the category mix is broad. The list includes healthcare AI (OpenEvidence), infrastructure (Hydra Host), security (Pillar Security and Guardz), IT operations (Flamingo), hospitality (Boom), construction (Togal.AI), financial services (Gail), HR (Erudit), and legal marketing (FirmPilot).
Second, funding is concentrated. OpenEvidence alone has raised roughly $700 million, and Hydra Host's $100 million Series A is the only other round above $60 million on the list. Most of the other companies raised seed or Series A rounds under $25 million, so their hiring is growing from smaller bases.
Third, Miami is often a headquarters rather than the main engineering location. Pillar Security and Guardz were founded in Israel, and Flamingo said only one of its roughly 35 employees was in Miami when it raised its seed round. For these companies, Miami hiring tends to start with sales, marketing, and customer success, while engineering stays where the company was founded.
For GTM teams, these companies are hiring quickly, and several are building their first U.S. sales teams. That combination is more useful when paired with hiring, leadership, technology, and data enrichment signals than when funding is viewed on its own. Teams researching related categories can compare this list with Landbase's rankings of healthcare AI startups hiring fastest and AI security startups hiring fastest.

How Landbase supports Miami AI startup account research
The ranking in this article was built with Landbase. A natural-language search identified AI startups headquartered in Miami and Fort Lauderdale with 30 or more employees. An enrichment step then added founding year, headquarters city, and 12-month headcount change, and the results were filtered and sorted into a structured dataset.
Landbase's web and CLI interfaces access the same account, datasets, and saved work.
For more complex requirements, the Advanced Dataset Creator supports filters, calculations, and custom output fields.
Landbase's data infrastructure includes more than 800 million contacts and more than 40 million companies across more than 1,500 fields, with enrichment from more than 20 providers.
A Miami workflow could, for example, identify AI companies headquartered in Miami-Dade or Broward that were founded outside the United States, raised a seed or Series A round in the past year, and recently hired their first U.S. sales or marketing leader in South Florida.
The Landbase CLI setup supports these workflows from a standard terminal and from AI coding environments including Claude Code and Codex.
Frequently Asked Questions
Which AI startups in Miami are growing fastest?
Based on 12-month headcount growth in Landbase data, the fastest-growing venture-backed AI startups headquartered in the Miami area include Flamingo, OpenEvidence, Hydra Host, Boom, Erudit, Togal.AI, Gail, Pillar Security, FirmPilot, and Guardz.
Which Miami AI startup grew headcount fastest?
Flamingo recorded the highest 12-month headcount growth among the companies that met this list's criteria, at about 200%, from a small base. OpenEvidence followed at about 180% and is far larger by funding, with a reported $12 billion valuation after its January 2026 Series D.
Why is Miami attracting AI startups?
Venture funding for AI-focused startups in the Miami metro rose to $1.23 billion in 2025, according to eMerge Americas. Miami also works as a U.S. headquarters for companies founded abroad, such as Guardz and Pillar Security, and the founders of Gail and Flamingo have described Miami as their long-term base for headquarters and go-to-market hiring.
Does headcount growth mean a Miami AI startup is growing quickly?
Not on its own. Headcount data can differ from company figures, and many Miami-headquartered companies employ most of their staff in other countries. This list therefore pairs headcount growth with disclosed funding, revenue, customer, and usage evidence wherever it is available.
How can GTM teams find fast-growing AI startups in Miami?
Teams can start with a headquarters and category definition, then filter by headcount growth, funding stage, recent rounds, target buyer, and hiring activity. Landbase can combine these criteria into reusable datasets and return company and contact information through web and CLI workflows.
