Guava, a voice AI startup, has raised a $12.5 million seed round led by Acrew Capital, according to a funding announcement distributed by Business Wire on November 3, 2026. Flourish Ventures also participated.
The company sells conversational voice AI as an API, and says the technology rests on more than a decade of model development at Gridspace, the speech company to which it traces its technology. The sources reviewed do not establish a formal spinout or corporate lineage.
Who backed the round
Flourish Ventures confirmed its participation in a November 3 investment memo written by Emmalyn Shaw, Evi Muco and Peter Lagrotteria. Chris Metinko of Axios Pro reported the financing the same day and attributed confirmation to Omri Dahan, Guava's chief executive.
There was an earlier pre-seed round. Dan Rosen of Commerce Ventures said in a public LinkedIn update that his firm led it. Neither the amount nor the date of that round appears in the sources reviewed, and a lifetime funding total could not be established.
The Gridspace connection
Guava's announcement describes Dahan as a former Gridspace investor and names Anthony Scodary and Nico Benitez as Gridspace's technical co-founders. The company's careers page says the platform is built on 13 years of production speech science, with regulated production use beginning in 2013.
Acrew's investment thesis, written by Lauren Kolodny, Asad Khaliq and Kunaal Patel, points to an existing relationship with Dahan through board service, co-investments and fintech work. The firm draws a line between his earlier experience at Marqeta, where card issuing was turned into developer infrastructure, and Guava's approach of offering voice as an API.
A model, a benchmark and some caveats

On September 23, 2026, Guava released a voice model called Daytona alongside the Guava Voice Index, or GVI, a benchmark for voice agents. The release describes a blend of automated scoring and blind comparisons against human agents, judged by an external evaluator panel.
Guava publishes the benchmark and also competes in it, a setup worth keeping in mind. The company acknowledges that a different weighting could change the ranking. Its funding announcement separately says Daytona placed near the top of Coval's word-error-rate benchmark, a claim that could not be independently verified.
Earlier, on September 8, Guava announced a partnership with CarrierX to bring 16 kHz HD voice to live customer calls.
On integrations, the company's healthcare page says reference deployments are available for Epic and Oracle Health, and also names Cerner and Meditech. Its materials for business process outsourcing firms list compatibility with Genesys, NICE CXone, Five9, AWS Connect and Twilio Flex. Neither page is dated, so it is unclear how current those lists are.
The FAQ is careful on compliance. It separates HIPAA-related controls and a business associate agreement from what it calls a purported "HIPAA certification."
A crowded field
Owning the full technology stack is not unique to Guava. Bland makes the same claim, and Vapi is another rival. Guava positions itself through a combination of integrated models, business logic controlled by developers, regulated workflows and a technology history originating at Gridspace. Its April 7, 2026 comparison with Vapi was written by the company itself and should be read accordingly.
Flourish's memo, according to the firm, discloses customer counts but not a named customer roster.
What comes next

Coverage of the round, including a report by Funding and Hiring, describes further development planned for edge applications, on-premises installations and full-duplex interaction, in which a system can listen and speak at the same time. Precise availability of those features was not confirmed.
Guava's careers page listed 10 open roles on November 4, 2026, across engineering, sales, growth, finance and operations, and governance, risk and compliance. Most are in Los Angeles.
