- Fish Audio
Participated · Seed · Jul 2026
Fish Audio develops AI speech generation and speech-to-text models and offers both open-source releases and paid API plans for creators, teams, and enterprises. The company has launched five models in the last year—three of which are open-sourced—and its S2.1 Pro model is available only through its paid API. Fish Audio reports more than 8 million users and $21 million in annual recurring revenue, and its GitHub Fish Speech repository has over 31,000 stars. It offers paid monthly plans that unlock generation minutes and voice cloning features, and it also runs enterprise APIs used by companies including HeyGen, Sanas and Plaud. The startup plans to release an audio understanding model this year and is building a speech-to-speech model as part of its roadmap. Fish Audio has also implemented an automated takedown process and creator verification flows to address consent and licensing concerns around uploaded voices.
- Sekai
Participated · Series A · Jun 2026
Sekai provides an AI-powered platform that translates plain-language prompts into functional, interactive mini-apps, enabling users to create games, utilities, and social tools in seconds. Its product features a social feed where users can share, remix, and engage with each other’s apps, borrowing viral mechanics similar to TikTok’s remixing. Within two months of launching its creation tools the platform hosted nearly 1 million mini-apps, with roughly half a million apps generated per month. Sekai uses AI coding agents to convert descriptions like “make a quiz about 90s movies” into working applications. The company targets consumer creators rather than enterprise product teams and is positioning itself to lower the barrier to interactive app creation. Following the Series A, Sekai plans to expand its AI creation platform and grow engagement on the network.
- Highlight
Participated · Series A · Mar 2026
Highlight builds a shared team memory and proactive command center that captures, models, and retrieves high-fidelity context across tools like Slack, Zoom, Linear, and Figma in real time. The platform combines user-controlled capture with a unified memory engine to synthesize meetings, decisions, ownership, and follow-up actions, and can draft follow-ups, create tasks, and sync documentation across systems. Highlight positions itself as an operating layer above apps to reduce coordination overhead and preserve institutional context as teams scale or roles change. The company announced a $40 million Series A to fund expansion and product work and appointed Sergei Sorokin, formerly VP of Product at Discord, as CEO. With the new capital, Highlight plans to double headcount and hire engineers, operators, and marketers in San Francisco to accelerate product development and go-to-market execution.
- 23 Broadway
Participated · Seed · Mar 2026
23 Broadway combines performance marketing expertise with a proprietary AI system called Atlas to determine optimal customer acquisition costs and predicted lifetime value. The company integrates non-dilutive capital deployment with marketing execution across major ad platforms, enabling partners to scale without building their own tech and marketing stacks. 23 Broadway’s performance team helped Betty capture an 18% market share in Ontario. With the new $3 million Seed financing, the company plans to further develop Atlas, enhance predictive modelling, and build AI-driven retention marketing models for gaming clients. It also intends to onboard additional partners seeking scalable user acquisition financing solutions.
- Rodeo
Participated · Seed · Mar 2026
Founded by former Hinge executives Sam Levy and Tim MacGougan, Rodeo helps users upload links or screenshots from TikTok, group chats, and other social platforms, then automatically extracts information such as addresses, reservation links, or ticket details and drops them into a collaborative, calendar-style planner. The product targets the gap between meeting new people and sustaining existing relationships by making it simpler to turn online inspiration into offline plans. The app has attracted 20,000 beta users and the team expects to open access to roughly 50,000 people following its latest capital raise. Rodeo currently generates no revenue and has not committed to a specific business model; management is exploring partnership-driven economics with platforms like Ticketmaster or OpenTable and a potential freemium subscription tier. Advertising is viewed as misaligned with the product’s intended usage patterns. Promotion has leaned heavily on organic TikTok content, where influencer interest has driven large wait-list numbers. The company has not disclosed its valuation.
