Thrilled that we at @FirstMarkCap are doubling down and leading @poshvip_ ’s $37M Series B. Huge congrats to @AvantePrice and the incredible Posh team. Posh is redefining how people create and discover meaningful IRL experiences while building for a future where connectors, community-builders, and culture-shapers have the tools to thrive. The future belongs to the connectors! @rick @vverawang

@rauchg @vercel Huge congrats @mitchellh @rauchg @vercel!! Few people have done more to shape modern dev infra, so this is a pretty special moment. Excited for what’s ahead!

It’s an honor to welcome Mitchell Hashimoto to the @vercel board. Mitchell built both an incredible company and foundational infrastructure, always putting open source and developers first. As the world is rebuilt with AI, I can’t think of a better person than an exceptional thinker like Mitchell to help us define the Agentic Infrastructure of the future. I can tell you the hype is real btw. Just having worked closely with him only for a few weeks, I see the magic. And, it also doesn’t hurt to have a *checks notes* direct line to ask for Ghostty features like session restoration and vertical tabs 😆

@davidneckstein @MaxJunestrand @siggelabor @WeAreLegora @FirstMarkCap Fired up to be on this journey with you and the team. LFG!

@abimbhet @MaxJunestrand @siggelabor @WeAreLegora You are an incredible partner! We are so lucky to have you in this round. I can't emphasize how much of a game-changer you and @FirstMarkCap have been, even before the money hit the bank. LFG!

Thrilled to partner with @MaxJunestrand, @siggelabor, @davidneckstein, Pat, Jacob and the entire @WeAreLegora team as they build the legal operating system for the AI era! Legal work demands judgment, precision, and trust. What’s exciting about this moment is that AI can actually support that work in a meaningful way, helping legal teams move faster, navigate complexity, and deliver high-quality work without compromising rigor. That’s a big part of why we’re so excited about Legora. They’re building the leading platform around how legal work actually gets done.

@MaxJunestrand @WeAreLegora @Accel Thrilled to be a part of it! LFG!

Big day at @WeAreLegora! We have raised $550 million at a $5.55 billion valuation in a Series D funding round, led by @Accel, to accelerate expansion across the United States. To all our customers and partners, this celebration is as much yours as it is ours.

@raincards Huge congrats team, thrilled to be partnering on the journey ahead!!

Onchain rails have proven their value. Rain is making them usable by everyone, and keeping them invisible in the process. Today, we’re announcing our $250M Series C at a $1.95B valuation to keep building. 🧵

2025 was a huge year for Rain, and our goals for 2026 are just as lofty. This round helps us get there. Expect to see better capabilities, more licenses, and products the world has never seen before. The future of money is here, and we're building the rails to make it possible.

Stablecoins are moving from crypto-native rails to real-world financial infrastructure: programmable, instant, and borderless ways to move dollars globally. At FirstMark, we believe the next era of global payments will be built by networks designed for the programmable economy. As money becomes tokenized and stablecoins become the most efficient way to access dollar liquidity globally, every institution will modernize how it transacts. Rain is building the infrastructure layer to power this shift: a full-stack platform spanning issuance, wallets, money movement orchestration, on- and off-ramps, and settlement - integrated with existing card networks to take friction out of global money movement. Rain is already moving billions in annualized volume, up 38x over the past year, across 200+ partners spanning crypto and traditional financial services - and they’re just getting started. We’re thrilled to be supporting @rooqster, @cnaut and the @raincards team! If you want to help build this future, get in touch - they're hiring! @adamn @vverawang

A major new entrant in voice AI: @GradiumAI If we were designing computers from scratch today, the default interface probably wouldn’t be a keyboard. It would be voice. Voice is the most natural interface we have, and probably the most underserved modality in AI today. We’re excited to announce that @FirstMarkCap is co-leading Gradium’s $70M seed round with Eurazeo alongside DST Global, Eric Schmidt, Xavier Niel, Rodolphe Saadé, Korelya, Amplify Partners and others. Gradium was founded in September 2025 by @neilzegh (Meta/Google DeepMind), @olivierteboul (Google Brain), @lmazare (Google DeepMind/Jane Street) and @honualx (Meta). Collectively they invented and open-sourced neural audio codecs and audio language models, and used this technology to power the very first voice cloning, text-to-music generation and speech-to-speech translation. They then created @kyutai_labs , a non-profit lab pushing the frontiers of multimodal LLMs, in particular releasing the first real-time conversational model in 2024. If you’re building anything voice-native – agents, games, learning tools, healthcare or something entirely new – you can start working with the product today at gradium.ai.
