AI agents are moving into everyday sales work. In a Salesforce survey published in February 2026, 54% of sellers said they had used AI agents, and nearly nine in ten planned to by 2027. The same survey found that 55% of sales professionals were already using AI for prospecting, with another 38% planning to do so.
Investors have backed the shift. Over 2025 and 2026, AI-native CRM, sales agent, sales enablement, and AI search visibility companies raised rounds from firms including Sequoia, Founders Fund, Battery Ventures, and Lightspeed. For B2B teams, that combination of funding and hiring is one of the clearest recent funding signals in software.
This list ranks AI-native sales, marketing, and go-to-market software companies 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 AI-native companies whose primary product is used by sales, marketing, revenue, or go-to-market teams, including AI SDRs and sales agents, AI-native CRMs, revenue intelligence and enablement, and AI marketing platforms.
Every company on the list had to meet four criteria:
- Founded in 2019 or later, which excludes established sales and marketing platforms that added AI features later
- Venture-backed, with at least one disclosed institutional round or named institutional investors
- Commercially available product sold to sales, marketing, or GTM teams, which excludes services firms, hiring marketplaces, and companies that have been acquired and are winding down
- 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, particularly for companies with contractors, distributed teams, or recent hiring changes. 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) Aurasell
CEO: Jason Eubanks
Latest round: $30 million seed, August 2025
12-month headcount growth: +1,043%
Category: AI-native CRM
What Aurasell builds
Aurasell describes its product as an AI-native GTM operating system that runs from first contact to signed contract. It offers a standalone AI-native CRM for startups and small businesses, and a layer that sits on top of existing Salesforce and HubSpot deployments for mid-market and enterprise teams.
Latest growth evidence
Aurasell launched publicly in August 2025, positioning itself as an AI-native CRM. Since then it has published customer case studies on replacing fragmented sales stacks, released an account and contact prioritization agent framework, and in October 2026 introduced Live Assist, which supports reps during live calls. The company says more than 250 GTM agents run on the platform.
Recent funding
The $30 million seed round came from N47, Menlo Ventures, and Unusual Ventures and was announced alongside the company's launch.
Why it matters
Aurasell is one of several companies on this list trying to replace the CRM rather than add to it.
2) Profound
CEO: James Cadwallader
Latest round: $180 million Series D, September 2026
12-month headcount growth: +478%
Category: AI marketing and AI search visibility
What Profound builds
Profound began by helping brands measure and improve how they appear in answers from AI assistants such as ChatGPT. It now positions itself as an AI platform for marketing.
Its flagship product, AI Marketer, monitors a company's data, proposes marketing work, and, once approved, handles briefs, drafts, review, CMS publishing, and performance reporting.
Latest growth evidence
Profound said in September 2026 that more than 2,500 brands use its platform, including a third of the Fortune 100 and several of the largest marketing agencies.
Its valuation moved from $1 billion at its February 2026 Series C to $1.8 billion at its September 2026 Series D.
Recent funding
Sequoia Capital and Kleiner Perkins co-led the $180 million Series D, with Lightspeed Venture Partners, Khosla Ventures, Saga Ventures, Evantic, and South Park Commons participating. Lightspeed had led the $96 million Series C seven months earlier.
Why it matters
Profound shows that AI search has created a new marketing budget line.
3) Monaco
CEO: Sam Blond
Latest round: $50 million Series B, May 2026
12-month headcount growth: +443%
Category: AI-native revenue platform
What Monaco builds
Monaco is building an AI-native revenue platform intended to replace a legacy CRM and the separate tools around it. The product acts as the system of record, builds a customer's total addressable market, runs outbound, captures customer interactions, and manages pipeline.
Latest growth evidence
Monaco's founding team includes Sam Blond, former CRO at Brex and Zenefits; Malay Desai, former chief architect at Clari; and Shek Viswanathan, former CPO at Apollo and Qualtrics. Monaco launched from stealth in February 2026 and, in its Series B announcement, said it had added seven figures of annual recurring revenue in each of February, March, and April.
Recent funding
Benchmark led the $50 million Series B, with returning investors Founders Fund and Human Capital participating. The round brought total funding to more than $85 million, following seed and Series A rounds led by Founders Fund.
Why it matters
Monaco targets the early-stage startups that typically assemble a CRM, data provider, and sequencing tool themselves.
4) Rox
CEO: Ishan Mukherjee
Latest round: Undisclosed round at a reported $1.2 billion valuation, March 2026
12-month headcount growth: +284%
Category: Revenue agents for enterprise sales teams
What Rox builds
Rox builds AI revenue agents for Global 2000 companies. The agents generate pipeline, qualify leads, book meetings, manage deals, and expand existing accounts.
Latest growth evidence
In March 2026, TechCrunch reported that Rox was projected to end 2025 with about $8 million in annual recurring revenue. Rox says it has served more than 5,000 organizations since leaving stealth.
Recent funding
Returning backer General Catalyst reportedly led that round; neither company confirmed it. Rox had previously raised $50 million through a Sequoia-led seed and a General Catalyst-led Series A.
Why it matters
Most AI sales agent companies started with small and mid-sized buyers. Rox is aimed at large enterprises, where account data sits in warehouses and deals span many teams.
5) Peec AI
CEO: Marius Meiners
Latest round: $21 million Series A, November 2025
12-month headcount growth: +262%
Category: AI search visibility analytics
What Peec AI builds
Peec AI, based in Berlin, helps brands and agencies track and improve how often and how favorably they appear in answers from AI assistants and AI search engines.
Latest growth evidence
Peec AI reported growth from zero to more than $4 million in annual recurring revenue in 10 months, with more than 1,300 brands and agencies onboarded since February 2025 and over 300 new customers added each month, according to its Series A announcement.
Recent funding
Singular led the $21 million Series A, with Antler, Combination VC, identity.vc, and S20 participating. The round followed a seed round led by 20VC in July 2025 and brought total funding to $29 million.
Why it matters
Peec AI and Profound both show how quickly marketers began budgeting for AI search.
6) 1mind
CEO: Amanda Kahlow
Latest round: $30 million Series A, November 2025
12-month headcount growth: +261%
Category: AI sales agents
What 1mind builds
1mind builds AI sales agents it calls "Superhumans," which engage, qualify, and convert buyers on websites, inside products, and on live sales calls.
Latest growth evidence
In March 2026, Clari + Salesloft named 1mind its exclusive AI successor to Drift, the conversational marketing product Salesloft had acquired. 1mind lists HubSpot, ZoomInfo, Pipedrive, and Alteryx among the companies featured in its published case studies.
Recent funding
Battery Ventures led the $30 million Series A, with Primary Ventures, Wing Venture Capital, Harmonic, Operator Collective, Alumni Ventures, and SuccessVP participating. The round brought total funding to $40 million.
Why it matters
Kahlow previously founded 6sense. 1mind's Drift partnership shows incumbent revenue platforms choosing to partner with AI-native agent companies rather than rebuild older chat products.
7) Letter AI
CEO: Ali Akhtar
Latest round: $40 million Series B, February 2026
12-month headcount growth: +259%
Category: AI revenue enablement
What Letter AI builds
Letter AI provides an AI revenue enablement platform. Its products cover AI roleplay and training, content creation and management, a company-specific AI assistant, RFP automation, and digital sales rooms.
Latest growth evidence
When it announced its Series A in October 2025, Letter AI said it had grown its customer base 15 times in the past year and quadrupled headcount during 2025.
Recent funding
Battery Ventures led the $40 million Series B in February 2026, with Y Combinator, Lightbank, Northwestern Mutual Future Ventures, Stage 2 Capital, and Formus participating. It came four months after a $10.6 million Series A led by Stage 2 Capital.
Why it matters
Sales enablement has long been dominated by content management platforms. Letter AI's back-to-back rounds suggest buyers want training, coaching, and deal support delivered by AI in one product.
8) Alta
CEO: Stav Levi-Neumark
Latest round: $25 million Series A, July 2026
12-month headcount growth: +152%
Category: AI GTM agents
What Alta builds

Latest growth evidence
Alta said it reached its first $1 million in revenue within months of commercializing and projected 800% revenue growth for the year, according to its Series A announcement.
Recent funding
IN Venture led the $25 million Series A, announced in July 2026, with Mindset Ventures, Skywell Capital, and LeumiTech77 joining existing investors Entrée Capital, Target Global, and Verissimo Ventures.
Why it matters
Alta packages several AI agents for outbound, inbound, and calling into a single system.
9) Hyperbound
CEO: Sriharsha Guduguntla
Latest round: $15 million Series A, September 2025
12-month headcount growth: +146%
Category: AI sales training and coaching
What Hyperbound builds
Hyperbound provides AI roleplays and coaching for sales teams. Reps practice cold calls, discovery, and objection handling against AI buyers, and managers use scoring to track readiness.
Latest growth evidence
Hyperbound said it added more than $1 million in new annual recurring revenue in each of two consecutive months before its Series A. Customers include Autodesk, Bloomberg, and Vanta.
Recent funding
Peak XV Partners led the $15 million Series A, with Y Combinator, Snowflake Ventures, Roble Ventures, and Fellows Fund participating. Total funding reached $18.3 million.
Why it matters
Hyperbound applies AI to rep readiness rather than outreach.
10) Brandlight
CEO: Imri Marcus
Latest round: $30 million Series A, February 2026
12-month headcount growth: +136%
Category: AI search brand visibility
What Brandlight builds
Brandlight helps large brands understand and influence how they are represented in AI search and AI assistant answers, including which sources models rely on when describing a brand.
Latest growth evidence
Brandlight said it had worked with dozens of Fortune 500 brands before announcing its Series A. In December 2025 it was named a leader in CB Insights' ESP ranking for generative engine optimization.
Recent funding
Pelion Venture Partners led the $30 million Series A, with existing investors Cardumen Capital and G20 Ventures participating.
Why it matters
Brandlight is the third AI search visibility company on this list.
What the AI sales and GTM rankings show
The companies above cover different parts of the revenue process, but several patterns repeat.
First, AI-native companies are going after the CRM itself. Aurasell and Monaco both pitch a single AI-run system of record in place of a CRM plus separate data, sequencing, and call tools, while Rox and Alta build agent layers that orchestrate work across existing systems.
Second, AI search has become its own marketing category. Profound, Peec AI, and Brandlight all grew quickly by helping brands track and shape how AI assistants describe them, and Profound's valuation rose from $1 billion to $1.8 billion in seven months.
Third, AI is moving into the sales conversation and rep development. 1mind puts AI agents on live calls, Letter AI combines enablement with deal coaching, and Hyperbound trains reps against AI buyers.
For GTM teams, these companies are hiring quickly, adding customers, and building new functions. 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 the wider category can compare this list with Landbase's earlier rankings of fast-growing sales tech companies and revenue intelligence platforms, as well as the top AI coding and developer tools startups.
How Landbase supports AI sales and GTM account research
The ranking in this article was built with Landbase. A natural-language search identified AI-native sales, marketing, and GTM software companies, an enrichment step added founding year 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. An audience created in the web app can move into a repeatable terminal workflow, and CLI-generated datasets remain available in the web app.
For more complex requirements, the Advanced Dataset Creator supports natural-language instructions involving filters, calculations, ratios, 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.
An AI sales and GTM workflow could, for example, identify AI sales agent and AI marketing companies that raised a Series A or later in the past year, grew headcount by more than 100%, recently hired a head of sales or marketing, and are headquartered in North America or Europe.
The Landbase CLI setup supports these workflows from a standard terminal and from AI coding environments including Claude Code and Codex.
Frequently Asked Questions
What counts as an AI sales and GTM company?
An AI sales and GTM company builds software that uses AI to help teams find, engage, win, and grow customers. The category includes AI SDRs and sales agents, AI-native CRMs, revenue intelligence and enablement platforms, AI sales training tools, and AI marketing platforms such as AI search visibility products.
Which AI sales startup grew headcount fastest?
Aurasell recorded the highest 12-month headcount growth in Landbase data among the companies that met this list's criteria, at more than 1,000%. The company launched in August 2025 with a $30 million seed round from N47, Menlo Ventures, and Unusual Ventures.
Why are AI search visibility companies growing so quickly?
Buyers increasingly ask AI assistants for product recommendations, which gives marketers a new channel to measure and influence. Companies such as Profound, Peec AI, and Brandlight track how brands appear in AI answers, and Peec AI reported reaching more than $4 million in annual recurring revenue within 10 months.
Does headcount growth mean a company is growing quickly?
Not on its own. Headcount data is based on professional profiles and can differ from company-reported figures, and fast hiring does not guarantee revenue growth. This list therefore pairs headcount growth with disclosed funding, revenue, customer, and valuation evidence wherever it is available.
How can GTM teams find fast-growing AI sales and marketing companies?
Teams can start with a category definition, such as AI-native sales and GTM software, and then filter by headcount growth, funding stage, recent rounds, geography, technology usage, and hiring activity. Landbase can combine these criteria into reusable datasets and return company and contact information through web and CLI workflows.
