Wispr has secured $280 million in Series B funding.
The round values the voice AI company at $2 billion. Menlo Ventures led the investment, with several existing and new backers joining. The raise brings Wispr’s total funding to $361 million.
The company now plans to move beyond voice dictation. It wants to enter meetings, enterprise workflows, and broader human-computer interaction.
Wispr is best known for Wispr Flow. The product turns spoken words into formatted text across applications. For busy professionals, this can speed up emails, reports, notes, and daily communication.
Alongside the funding, Wispr introduced Canto, its own speech model. The company says Canto improves transcription in difficult environments. These include noisy rooms, strong accents, and multilingual conversations.
Wispr claims Canto can cut error rates sharply in tough conditions. It says errors can fall from above 30 percent to between 5 percent and 10 percent. It also says everyday dictations may need 30 percent to 35 percent fewer edits.
However, the company has not shared full testing details. It has not named comparison models, languages, or audio conditions. Enterprise buyers will likely ask for clearer benchmarks before large deployments.
Deedy Das, Principal at Menlo Ventures, highlighted the challenge on X:
“Winning on the app layer is difficult: software is easier to replicate than ever before (what’s the moat? Can’t I just vibecode this?) so you have to maniacally focus on product quality, growth, retention and monetization while scaling your infrastructure, spinning up enterprise sales and growing a world class team. It is much easier said than done.”
“Products that seem simple on the surface like voice dictation or video creation hide a ton of this complexity under the hood.”
The timing is important for unified communications teams. Voice input often fails in real workplaces. Open offices, travel, weak microphones, and background noise remain common issues.
Wispr also says Canto supports code-switching. This means users can move between languages in one sentence. That feature matters for global teams and multilingual contact environments.
The company is also entering meeting intelligence. Its new Flow Notetaker creates summaries and action items from meetings. This places Wispr in a crowded market.
It will face specialists such as Fireflies, Read AI, and Granola. It will also compete with built-in tools from Zoom, Microsoft Teams, and Google Meet.
Wispr’s cross-platform approach could appeal to enterprises using mixed collaboration stacks. Yet integrations will be critical. Customers will expect links into productivity suites, CRM systems, chat platforms, and compliance tools.
Security and governance may decide the next stage. Wispr has not fully detailed data retention, residency, or training policies. It also has not clarified all opt-out controls for enterprise customers.
That matters because meeting data can include sensitive conversations. IT leaders need clear rules for consent, storage, and access.
Wispr now has significant capital and strong market momentum. Its challenge is clear. It must prove that voice AI can deliver accuracy, trust, and workflow value at enterprise scale.
