Avante Banks $30M Series A to Automate Benefits With AI Agents

Avante has raised a $30 million Series A to replace benefits spreadsheets with AI agents, bringing its total funding to $40 million. Frist Cressey Ventures led the round, with new investors Sorenson Capital, Hearst Ventures and the Morgan Stanley Next Level Fund joining existing backer FUSE.

The Seattle company, live for just 18 months, reports more than 70 customer accounts, bookings up nearly fivefold year over year, and a 100% renewal rate among customers eligible to renew. Its platform now covers more than 385,000 employees and family members, according to the announcement.

Why benefits teams are the target

Benefits teams control one of the largest line items in corporate spending, yet many still assemble renewal decisions from spreadsheets, claims reports, contracts and email threads. Evaluating a vendor alone means comparing contractual commitments against claims, utilization and service data — before a negotiation even starts.

"Benefits teams are responsible for one of the largest and most consequential investments their companies make, yet they're still operating with outdated information, archaic spreadsheets, and technology built for another era," said Rohan D'Souza, Avante's CEO and co-founder, in the announcement.

Avante's answer is a pair of agents. Ava works for employers, comparing contracts with actual claims, reviewing plan documents for errors, tracking deadlines and drafting leadership reports. Carly serves employees with personalized, around-the-clock guidance on their own plans and options. The company says repeated employee questions can also flag gaps that the benefits team should fix.

What does the new money change for practitioners?

The capital funds global expansion and further development of the agent platform. That matters for multinational employers, who must reconcile programs that differ by country, plan year and employee population. Avante's core architecture — what it calls a Benefits Ontology — connects plans, populations and eligibility rules in a structured model, so an agent's answer reflects the right plan year and the right person.

The announcement follows the beta launch of Ava Agents, which runs recurring benefits work in the background. Connect a mailbox, and an incoming vendor report can trigger a contract comparison; if documents are missing, Ava drafts the follow-up, monitors the response and hands the team a sourced brief with findings and a draft reply. Humans approve everything that gets sent.

The company doesn't train its own foundation models. It uses models from OpenAI, Anthropic and Google, and layers domain-specific processing on top: document handling, retrieval, task routing and controls. Responses cite source sections and are evaluated in real time, with flagged answers available for human review — product controls, not a guarantee of error-free output.

The customer numbers, with caveats

Avante names partnerships with benefits advisors including Gallagher, OneDigital, Segal Benz, Howden and USI Insurance Services. The customer results it cites are company-supplied:

• At Real Chemistry, 83% of the U.S. workforce has engaged with Avante. Olga Reupert, SVP of Total Rewards, HR Global Operations and Enablement, said on-demand guidance has cut administrative burden and freed the benefits team for strategic priorities.
• Samsung Semiconductor reported 66% more employees and dependents found and used existing mental health support — an increase in utilization, not two-thirds of the workforce using the benefit.
• Personify Health said the platform answered more than 8,500 employee questions over the past year.

Employees reach Carly through Slack, Microsoft Teams, ServiceNow, email and a branded portal. The background agents remain in beta, which Avante distinguishes from its broader platform already in production.

The Series A lands amid a broader push of AI into HR operations. Avante's next test is converting early adoption into a repeatable operating model for global benefits teams — with the $30 million buying the runway to connect program analysis, vendor accountability and employee guidance on one platform.
