Silicon Valley is licking its chops at the promise of AI 'agents.' These are the startups to watch.

Sam Altman, the CEO of OpenAI, has prophesied that this may be the year the first "agents" — a set of artificial intelligence tools that can perform tasks on their own — "join the workforce." Investors whose job it is to back new technologies before they become ubiquitous are swooning at the promise of these digital coworkers.

The rise of agents offers fertile ground for a select group of startups to establish themselves as the front-runners of this shift. In that spirit, Business Insider reviewed press releases, news articles, and PitchBook data for startups exploring the application of agents across various sectors and then filtered for those companies that raised rounds of more than $25 million and less than $75 million in 2024. The result is a list of 21 startups that seem positioned to scale this year on the back of new funding.

"If 2024 was the year of LLMs, we believe 2025 will be the year of agentic AI," said Praveen Akkiraju, a managing director at Insight Partners, whose agentic plays include Writer, Jasper, and Torq.

The last wave of artificial intelligence brought copilots, a type of virtual assistant designed to work side-by-side with a user. Some write code, some recap meetings or emails, and some transcribe notes on a physician's behalf. Copilots require some human hand-holding but significantly amplify productivity and efficiency.

Since that breakthrough, a new generation of virtual assistants has emerged. Agents describe an artificial intelligence that can complete tasks without much human supervision. They don't just assist — they take charge. Agents can break down complex tasks into smaller sub-tasks, make decisions, execute plans, and adjust their approach based on outcomes.

Here's a simple way to think about the difference: a copilot can assist with crafting a tailored vacation itinerary, while an agent can go further by booking the flights, reserving the hotel, and organizing activities — all without a user needing to intervene at each step.

With Google, Microsoft, and OpenAI's significant investments in agentic models and the subsequent investor hysteria around this technology, it's clear that agents are the flavor of the season. PitchBook data shows startups exploring the application of agents have raised $8.2 billion in 2024.

Jill Chase, a partner at CapitalG, a growth fund under Alphabet, said software infrastructure that makes agents work "will be poised for explosive growth." Aaron Jacobson, a partner at NEA and an early investor in Databricks, said enterprises will deploy agents at large to "make a real business impact." Seema Amble, a partner at Andreessen Horowitz, suggested that agents will change how professionals use software.

"In the short term, human workers will be the reviewer in the loop," said Amble, an enterprise software investor. "In the future, as trust is established over time, I expect many data-derived actions will shift toward being entirely a set of narrowly defined task-driven agents."

Here's a list of agentic startups that have raised rounds of more than $25 million and less than $75 million in 2024, ranked from the least to most money raised.
