All Talk, All Action

Note: This article is primarily an event announcement for the Cerebral Valley Voice Summit (May 6, San Francisco). Substantive analysis is limited, but the speaker roster and framing carry meaningful signal for investors and operators tracking the voice AI space.

1. Key Themes

Voice AI Is the Next Major Interface Shift

The summit is framed explicitly around this thesis, described as "the next great interface shift." The convergence of infrastructure players (LiveKit, Deepgram, Cartesia), application builders (Wispr Flow, Assort Health, Regal, ASAPP), and Big Tech (OpenAI's realtime AI lead) at a single event signals institutional momentum around voice as a platform.

"If you want to attend the summit on the next great interface shift, spots are filling fast."

The Voice AI Stack Is Maturing Into Distinct Layers

The speaker lineup maps cleanly onto a full stack — real-time infrastructure (LiveKit), speech-to-text (Deepgram), text-to-speech/voice synthesis (Cartesia), dictation/productivity (Wispr Flow), vertical applications (Assort Health, ASAPP, Regal, Speak), and platform (OpenAI Realtime). This suggests the ecosystem is maturing beyond single-vendor solutions.

Speakers include Russ d'Sa (LiveKit), Scott Stephenson (Deepgram), Karan Goel (Cartesia), Justin Uberti (OpenAI, head of realtime AI), and Tanay Kothari (Wispr Flow).

Enterprise Deployment of Voice AI Is a Real and Active Market

The inclusion of Assort Health (healthcare), ASAPP (enterprise contact center), and Regal (AI-powered outbound calling) signals that voice AI is moving from demos into production enterprise use cases with meaningful revenue potential.

Speakers include Jeff Liu (Assort Health), Priya Vijayarajendran (ASAPP), and Alex Levin (Regal) — all leading discussions at the summit.

Tier-1 VCs Are Actively Deploying Into Voice AI

The presence of a16z, Lux Capital, Scale Venture Partners, M13, and Felicis as either speakers or sponsors signals that top-tier capital is organized around this theme — not just watching it.

Speakers include Olivia Moore (partner, Andreessen Horowitz) and Grace Isford (partner, Lux Capital), with Felicis sponsoring a speakers' dinner.

2. Contrarian Perspectives

High-Profile Summits Are Legitimate Deal Origination Venues — Not Just Networking

The conventional wisdom treats industry conferences as branding exercises. This newsletter challenges that with two concrete, high-value outcomes directly attributed to prior Cerebral Valley summits.

"Databricks bought MosaicML for $1.3 billion after Ali Ghodsi met Naveen Rao at our first Cerebral Valley AI Summit. Suno's $250M Series C began at our Cerebral Valley AI Summit."

This suggests curated, small-format AI summits — not Davos-scale conferences — may be where transformative deals are actually initiated.

OpenAI Is Competing Directly With Its Own Ecosystem Partners

The presence of Justin Uberti, OpenAI's head of realtime AI, at a summit also featuring independent voice infrastructure providers (LiveKit, Deepgram, Cartesia) highlights a structural tension: OpenAI is both a platform and a direct competitor to the companies building on top of it.

Justin Uberti, "head of realtime AI, OpenAI" is listed alongside independent voice infrastructure CEOs — companies whose core products overlap with OpenAI's Realtime API.

5. Operating Insights

Curated Small-Format Events Outperform Large Conferences for Deal Origination

The newsletter provides two data points suggesting that intimate, curated AI summits — not broad industry conferences — are where transformational deals actually close. For founders and investors, prioritizing attendance at focused, high-signal gatherings over mass-market events may generate disproportionate ROI.

"Databricks bought MosaicML for $1.3 billion after Ali Ghodsi met Naveen Rao at our first Cerebral Valley AI Summit. Suno's $250M Series C began at our Cerebral Valley AI Summit."

Sponsorship of Niche AI Summits Buys Direct Access to Decision-Makers

Baseten's sponsorship includes hosting a private CTO dinner — a high-leverage format that places their brand in front of technical buyers in an intimate setting, not just on a banner. For B2B AI infrastructure companies, event sponsorship structured around exclusive dinners may be a more efficient GTM motion than broad conference presence.

"We're hosting a dinner with CTOs of top voice AI companies ahead of the summit with Baseten."

6. Overlooked Insights

Emergence Capital's Jake Saper Is the Only Traditional Enterprise SaaS VC on the Speaker List

While a16z, Lux, Scale, and M13 all have representation, Emergence Capital — known for calling the "SaaS" category early and backing Salesforce, Zoom, and Veeva — signals institutional conviction from a firm with a long track record of identifying durable enterprise software categories. Their presence suggests voice AI may be entering the "enterprise software category" phase of maturation.

"Emergence Capital's Jake Saper" listed among previously announced speakers.

Rime — A Lesser-Known Voice Synthesis Company — Is Being Elevated Alongside Category Leaders

While Deepgram and Cartesia receive headline speaker slots, Rime's co-founder is leading a breakout discussion group, quietly placing them in the same tier of influence. For investors tracking the text-to-speech infrastructure market beyond ElevenLabs and Cartesia, Rime may be an underexamined player.

"Lily Clifford, co-founder and CEO, Rime" listed as a discussion group leader.
