1. Introduction ― Why "Asynchronous Meetings" Now

Since the start of 2026, the term "Asynchronous Meeting" has once again become a frequent topic of conversation among Silicon Valley investors and startup executives. While there are multiple factors behind this, the biggest driver is the announcement on March 25 of a $125 million Series C raise by AI meeting notes app Granola (approximately ¥18.7 billion). The round was led by Index Ventures with additional investment from Kleiner Perkins, pushing the valuation to $1.5 billion (approximately ¥225 billion). Granola has gained traction with its design philosophy of "not bringing a bot (a recording AI as a participant) into meetings," and its concept of meetings that are easy to convert to asynchronous formats, premised on post-meeting summarization and sharing.

At the same time, Loom — the asynchronous video messaging platform acquired by Atlassian in late 2023 for $975 million (approximately ¥146 billion) — completed deep integration with Jira and Confluence in 2026 and began operating in conjunction with Atlassian Intelligence's summarization layer. This has allowed the practice of "advancing decisions without holding meetings" to begin taking genuine hold in the enterprise — and that is the backdrop for why Silicon Valley venture capitalists are once again treating this theme as "hot."

2. What is an "asynchronous meeting" in the first place?

2.1 Definition

An asynchronous meeting is a meeting format in which decisions are made by having participants "post" and "respond" to agenda items at their own convenience, without everyone gathering online or offline at the same time. It is the polar opposite of real-time meetings (synchronous meetings such as Zoom, Google Meet, and Teams), and generally takes the following form.

1. The initiator creates "context": They summarize the agenda, background, options, and information needed for decision-making in a short video (Loom, Vidcast, etc.) or text document (Notion, Confluence, Google Docs).

2. Participants read/watch at their own pace: This primarily involves watching videos at 1.5x speed and reviewing via comment features.

3. Discussion happens through comments: Slack threads, Twist, Loom comments, Notion comments, etc.

4. Decisions are finalized by a deadline: Wrapped up using operational rules such as the RACI method, Amazon's "disagree & commit," or GitLab's "DRI (Directly Responsible Individual)."

In short, it is a concept that removes the premise that "a meeting = gathering in person at that moment," and redefines "the decision-making process itself" as the meeting. It resembles email-based approval workflows, but differs significantly in that the combination of video, documents, and AI summaries conveys "warmth" and "facial expression."

2.2 Differences from Synchronous Meetings

AspectSynchronous Meeting (Zoom, etc.)Asynchronous Meeting
SchedulingForces a block on everyone's calendarDoes not disrupt each person's "deep work time"
Record-keepingRequires follow-up minutes afterwardInformation is captured at the time of posting and automatically becomes the record
Global compatibilityTime differences result in late-night or early-morning callsParticipants can contribute equally regardless of time zone
Decision speedResolved in one session, but requires waiting until everyone assemblesNo assembly required, but deadline management is necessary
Information biasEasily dominated by the loudest voicesMore equitable since it is document/video-based
Unsuitable topics—Brainstorming, 1-on-1s, crisis response

Rather than a fundamentalist approach of "making all meetings asynchronous," the mainstream thinking is "Default to Async (async by default, sync as the exception)". This is a practical philosophy shared by GitLab (a fully remote company operating with 1,600+ employees across 60+ countries), Doist (makers of Todoist / Twist), Automattic (WordPress.com), and Basecamp, among others.

2.3 Typical Formats for Asynchronous Meetings

The following are representative formats used in Silicon Valley.

  • Loom-style video standups: Once a day, each person records a 2–5 minute video documenting their progress and any blockers.
  • Amazon-style 6-pager: A 6-page memo on the agenda is circulated in advance, and discussion is concluded through comments.
  • Shape Up (Basecamp)-style Pitch: Project proposals are documented, and investment decisions are made asynchronously.
  • RFC / ADR (Architecture Decision Record): Engineering teams document technical decisions in writing.
  • Async Retro: Sprint retrospectives conducted over 72 hours using sticky notes and comments in Miro or FigJam.

3. How Silicon Valley VCs Are Perceiving This

3.1 Andreessen Horowitz (a16z) — Treating "Default to Async" as a Core Principle

a16z has consistently tracked collaboration in the remote and hybrid era through blog posts such as "Are we returning to the office? Or is the future remote?" (2021) and "Hybrid Anxiety and Hybrid Optimism." In posts from 2025–26, partners Marc Andreessen and Ben Horowitz themselves have made clear their stance that "synchronous meetings are a 'tax on attention resources.'" Across the a16z portfolio, as CEOs with packed calendars become bottlenecks in decision-making, a growing number of investors are advising their portfolio companies to "put important matters into writing and work through them asynchronously."

3.2 Sequoia Capital — A Culture of "High Information-Density Documents"

Sequoia is known as an early investor in Loom (Series A), and its partners Shaun Maguire and Pat Grady have repeatedly stated that "asynchronous collaboration creates the time for humans to carefully review AI outputs." Grady in particular is reported to have advised AI portfolio companies such as Harvey and Glean to "reduce meetings and reallocate that time to reviewing AI-generated work product" (as reported by The Information, February 2026).

3.3 Kleiner Perkins — Bridging to Enterprise AI via Granola

Kleiner Perkins partner Mamoon Hamid is a Loom Series B/C investor and is known for serial investments in collaboration startups including Figma, Slack, and Front. Kleiner Perkins also participated in the Granola Series C in March 2026, and Hamid wrote in his own notes: "Meetings are becoming a venue for 'context sharing' rather than decision-making. A world where AI summarizes that context and goes out to collect decisions asynchronously will become the standard."

3.4 Lightspeed Venture Partners — The "Workplace Collaboration Map"

"Mapping Workplace Collaboration Startups," published on Medium in 2020 by Lightspeed's Merci Victoria Grace, remains a foundational reference among VCs in this space. The piece categorized async collaboration into four layers: "team messaging," "document collaboration," "video," and "decision-making / project management." A 2025 revision added a fifth layer: "AI Summarization / Meeting Intelligence."

3.5 Index Ventures — Lead Investor in Granola

Danny Rimer of Index Ventures, who led the Granola Series C, commented: "Meetings are black holes for productivity, but they are also treasure troves of information. Granola is the 'entry point' that structures that information and feeds it to AI — it will become the core data infrastructure of the async meeting era." Index has a track record of investing in companies that "change the way we work," including Slack, Figma, Roblox, and Discord, and this investment is a natural extension of the firm's consistent investment thesis.

3.6 European VCs (Atomico / Accel London)

There is significant interest from Europe as well. London-based Atomico has long recommended "Async First" to European startups, for whom working across time zones is an inherent reality. Accel London has supported the ecosystem around the async tool Twist through Doist (headquartered in Chile, with Accel as an early investor) and has continued to back remote-first companies.

3.7 How Japanese VCs Are Responding

Japanese firms such as Global Brain and DNX Ventures have been somewhat cautious, with the mainstream view being that "async improves productivity but carries the risk of slowing down the pace of building company culture." However, for startups targeting global markets, there is a growing trend of advising them to "design with async as the default from day one, in an English-language document culture" (from remarks at the JVCA February 2026 seminar).

4. Reporting tone of each newspaper/website

4.1 TechCrunch

  • "Granola raises $125M, hits $1.5B valuation" (March 25, 2026) positioned Granola as "asynchronous middleware that turns meeting byproducts into productivity."
  • The 2023 article "Atlassian to acquire former unicorn Loom for $975M" highlighted Atlassian co-CEO Mike Cannon-Brookes's statement: "Async video is the next evolution of team collaboration."

4.2 The Information / Business Insider

  • The Information published a lengthy article titled "Meetings are the new email" (January 2026), framing overwhelmed workplaces as a "productivity crisis" and characterizing the lag in asynchronous adoption as "the greatest opportunity cost of the AI era."
  • Business Insider reported in February 2026 on major companies — including Salesforce, HubSpot, and Rippling — implementing a company-wide No Meeting Wednesday policy.

4.3 Wall Street Journal / Financial Times

  • The WSJ heralded the dawn of the "Async Meeting era," covering Zoom's flat MAU figures in its quarterly earnings and enhancements to Microsoft Teams' "Intelligent Recap" feature.
  • The FT analyzed case studies from European companies (SAP, Spotify, Klarna), concluding that "culturally, Europe is more receptive to asynchronous work than North America."

4.4 Harvard Business Review

  • The March/April 2026 issue of HBR featured a special report titled "The Async Advantage," in which MIT Sloan Professor Erik Brynjolfsson commented that "async can only outperform sync when combined with AI."

4.5 Atlassian Work Life Blog

  • Though a branded blog run by Atlassian itself, an article titled "The future of work is asynchronous" offers concrete prescriptions for adoption. It advocates for "Document-first meetings" using Loom and Confluence in tandem.

5. Key Services / Products and Investors

Organizing the key players behind asynchronous meeting implementations from a Silicon Valley VC perspective.

5.1 Loom (under Atlassian)

  • Overview: Records short-form videos via browser extension and desktop, shared with a single URL. Over 5 million video messages per month, 25 million users.
  • Funding & Acquisition: Raised over $200 million cumulative (approx. ¥30 billion) from Sequoia, Kleiner Perkins, Coatue, and others. In October 2023, acquired by Atlassian for $975 million (approx. ¥146 billion).
  • Strategy: In 2026, integrated with Atlassian Intelligence to automate video → text summary → Jira issue creation.

5.2 Granola

  • Overview: A bot-free AI note-taker that lives in the Mac menu bar. Listens to meeting audio locally and generates Notion-like notes. Launched Spaces (team workspaces) and Enterprise API in 2026.
  • Funding: Series A $20 million (approx. ¥3 billion, 2024), Series B $43 million (approx. ¥6.4 billion, May 2025), Series C $125 million (approx. ¥18.7 billion, March 2026, led by Index Ventures with additional participation from Kleiner Perkins), valuation of $1.5 billion (approx. ¥225 billion).

5.3 Notion

  • The icon of asynchronous documentation. Since late 2024, has integrated Notion AI Q&A and Notion Calendar, becoming the standard OS for "document-first meetings." Total funding of $340 million (approx. ¥51 billion, from Sequoia, Index, Coatue).

5.4 Krisp

  • Meeting intelligence born from noise cancellation. Strengthened post-meeting summaries and action item extraction, along with Salesforce and Slack integrations. Series B $12 million in 2021 (approx. ¥1.8 billion, Storm Ventures), additional Series C funding in 2025.

5.5 Fireflies.ai / Otter.ai

  • Veteran "bot-type" services that automatically transcribe and distribute meeting audio. Fireflies.ai is backed by Khosla Ventures, Canaan, ICONIQ Growth, and others. Otter.ai has raised $63 million (approx. ¥9.4 billion), primarily from Horizons Ventures.

5.6 Vidcast (Webex by Cisco), Vimeo Record, Zoom Clips

  • Legacy meeting vendors' countermeasures with an added asynchronous video layer. Vimeo Record in particular has surged as a "Loom alternative."

5.7 Twist (Doist)

  • In contrast to Slack's real-time nature, built around a "thread-centric" design that assumes asynchronous communication. Doist is a fully bootstrapped company and a prime example of global expansion without VC money.

5.8 Range, Geekbot, Status Hero

  • Tools for running asynchronous standups on Slack. Range has raised approximately $30 million (approx. ¥4.5 billion) from Google Ventures, First Round, and others.

5.9 Around

  • A "lightweight Zoom" offering immersive small-window video calls. Acquired by Miro in 2023 and integrated as an asynchronous video feature on Miro's boards.

5.10 Gong, Chorus.ai (under ZoomInfo)

  • Provides "conversation intelligence" for sales meetings. Gong has raised a cumulative $583 million (approx. ¥87.5 billion) from Sequoia, Coatue, Franklin Templeton, and others, with a peak valuation of $7.2 billion (approx. ¥1.08 trillion). Enables asynchronous review of business negotiations.

6. New Technology Trends ― Three Layers Accelerating Asynchronous Meetings

6.1 "Bot-less" Audio Capture

The approach pioneered by Granola of "not inviting an AI bot as a meeting participant." It is gaining support for balancing privacy and UX. Apple Silicon's Core ML and NPU extensions are the backdrop, and the arrival of on-device transcription at a practical level has been the decisive factor in its widespread adoption.

6.2 Meeting Intelligence and RAG (Retrieval Augmented Generation)

A mechanism that accumulates meeting audio, video, and documents in a Vector DB, making them searchable later via natural language. Glean, Harvey, and Read.ai are competing in this space. A new UX is emerging: "Don't attend the meeting, but be able to query all past meetings."

6.3 Agentic "Proxy Attendance"

Agentic AI developed by Sierra, Adept, 11x.ai, and others provides context to meetings on behalf of participants and brings back decisions. In the second half of 2026, "AI proxy attendance" features are expected to be incorporated into Microsoft Copilot and Google Gemini as well (per Gartner's 2026 "Hype Cycle for Future of Work").

7. Future Roadmap ― When and What Will Happen

Based on a synthesis of comments from various VCs and analysts, the following milestones are anticipated over the next 18 months.

  • Q2 2026 (April–June)

- At Atlassian Team '26 (late April, Anaheim), a full integration demo of Loom × Jira × Rovo (Atlassian AI Agent) is expected.

- Dropbox has announced a major update to Capture (async video).

  • Q3 2026 (July–September)

- Notion has announced the official rollout of a native "Meetings" feature (from the Make '26 user conference in March).

- Zoom AI Companion 3.0 is expected to enter beta with an "Async Mode" (as reported by The Information).

  • Q4 2026 (October–December)

- At Microsoft Ignite, Teams' "Intelligent Recap" is expected to be integrated as a time-zone-aware "Async Huddle" feature.

- Granola aims to deeply integrate with Salesforce, HubSpot, and Workday via API, targeting a "memory layer" position within the SaaS ecosystem.

  • First Half of 2027

- Gartner predicts that global companies adopting a "Default-to-Async" approach will grow from 12% in 2025 to 38% by the end of 2027 (Future of Work Hype Cycle, 2026 edition).

- The McKinsey Global Institute estimates that the shift to asynchronous meetings will free up approximately 170 hours per knowledge worker per year (The Economic Potential of Async, January 2026).

8. Case Studies ― Successes and Failures

8.1 GitLab (Success Story)

An organization of over 1,600 people across more than 60 countries operating fully remote, managed through a 2,700-page public handbook and an "async by default" rule. Synchronous meetings are treated as a "bonus," and videos and meeting minutes are always recorded for those who cannot attend. The culture has been maintained even after going public, with sales productivity exceeding the industry average.

8.2 Doist (Success Story)

Uses its own product Twist internally, with members distributed across more than 35 countries. CEO Amir Salihefendić explicitly rejects what he calls "the curse of real-time communication," choosing Twist over Slack.

8.3 Zapier, Automattic, and Basecamp

All three embraced remote and asynchronous work from their founding days and have maintained stable, profitable structures without going public. From a VC perspective, they serve as prime examples of the use case that "if you're aiming for high margins rather than high growth, async becomes a competitive advantage."

8.4 Cases Cited as Failures

In 2024, a major SaaS company introduced "No Meeting Fridays" in a top-down manner, but a culture of documentation never took hold, and micromanagement via Slack DMs persisted — resulting in an increase in "shadow meetings" held outside official channels (from an HBR article, March 2026). An a16z partner commented on this: "Async without cultural infrastructure is simply the invisibilization of meetings."

9. Silicon Valley VC's Integrated Perspective ― Why This Is an "Investment Theme"

Finally, here is a summary of the common views among Silicon Valley VCs that emerged from this series of interviews.

1. As AI output increases, human "review time" becomes the bottleneck. Async meetings are the only mechanism to distribute this review across each individual's optimal time.

2. Meeting data is the "training corpus for enterprise AI" itself. What Granola, Loom, and Gong are targeting is a monopoly on this "decision-making corpus."

3. Async meetings create a "horizontal integration layer" for SaaS. Because they can supply "summarization," "decision-making," and "search" across Jira, Salesforce, Workday, and GitHub alike, the next generation of Zapier, Slack, and Notion candidates are likely to emerge from this space.

4. Zoom / Teams / Google Meet's "synchronous middleware" is entering a deceleration phase. Their additions of async features are defensive moves, giving pure async startups a competitive advantage.

5. "Async as a Service" is becoming a new category. Looking collectively at the acquisition of Loom, Granola's rapid growth, and Notion's entry into meeting features, the market size of this category is estimated to reach $12–15 billion (approximately ¥1.8–2.3 trillion) by 2028 (Gartner, Bessemer State of the Cloud 2026).

10. Conclusion

For Silicon Valley VCs, asynchronous meetings are "prerequisite infrastructure for leveraging AI" — transcending mere work-style discussion to sit at the center of investment themes. Loom's absorption into Atlassian, Granola's rapid ascent, the expansion of document-centric companies like GitLab, Doist, and Notion, and the explicit backing of a16z, Sequoia, Kleiner Perkins, Index, and Lightspeed — all of these point to a definitional shift: "meetings are not about 'gathering together,' but about 'the decision-making process itself.'"

For Japanese companies and Japanese startups with an eye toward global expansion, designing a culture that treats asynchronous meetings as the default and synchronous communication as the exception is rapidly becoming not a choice, but a given. The next wave to emerge from Silicon Valley will likely materialize in the latter half of 2026, with Atlassian Team '26 and Microsoft Ignite as inflection points — manifesting as async transformation at the "OS level" of the enterprise.

10. Conclusion

For Silicon Valley VCs, asynchronous meetings are "prerequisite infrastructure for leveraging AI" — a central investment theme that goes far beyond mere work-style discussion. The merger of Loom into Atlassian, Granola's remarkable momentum, the expansion of document-centric companies like GitLab, Doist, and Notion, and the explicit backing from a16z, Sequoia, Kleiner Perkins, Index, and Lightspeed — all of these suggest a fundamental redefinition: "meetings are not about 'gathering together,' but about 'the decision-making process itself.'"

For Japanese companies and Japanese startups as well, if global expansion is on the horizon, a cultural design that treats asynchronous meetings as the default and synchronous meetings as the exception is rapidly becoming not a choice, but a given. The next wave of movement in Silicon Valley will likely materialize in the latter half of 2026, around Atlassian Team '26 and Microsoft Ignite, as asynchronous transformation at the "OS level" of the enterprise.
