Congratulations @charlieholtz and the entire @conductor_build team!

[Charlie Holtz @charlieholtz]

I am very excited to share that Conductor is joining Meta!

We have some big, crazy plans for the next interface. If you liked Conductor, you’re gonna love what’s coming.

We’re super excited to work with @natfriedman and @alexandr_wang at MSL to build it. They’ve been on an absolute tear, and I’m convinced MSL has the highest talent density of all the labs.

A huge thank you to our earliest believers @aaron_epstein, @ilyasu, and @nabeel. And to everyone here who tried Conductor, sent us feedback, and prompt requests - you made this so much fun. Thank you ❤️🚂

Choo choo!

Congratulations to the @GeneralMedicine team on the $120M Series B led by @a16z. Proud to have incubated and backed the company from the beginning, and excited to have @tjparker leading its next phase of growth.

[TJ Parker⚡️ @tjparker]

General Medicine has raised a $120M Series B led by @a16z. We're using it to build the healthcare store.

The only way healthcare will work is to make the customer the most powerful participant in the system. And the only way to do that is to let them shop.

Here’s why healthcare needs a store, and what we had to build to make it possible:

[Matt Brown @Mattbrown]

Thrilled to announce Light's $46M Series A, led by @matrixvc ⚡️

Light is a fully regulated electricity provider that lets any company launch embeddable, programmable, and customizable energy products for their customers.

100% of new electricity brands entering the Texas market in 2026 launched on Light and revenue is up >10x. The rest of the country is next.

I’m excited to join the board and work with Baker, Adam, and team!

[TJ Parker⚡️ @tjparker]

Healthcare’s data problem is now fundamentally an engineering problem, and @metriport is the best technical team I’ve seen tackle it. The result is a meaningfully better customer experience everywhere they’re deployed (incl amzn + gm). Proud to have led their latest $26M round.

[Suno @suno]

We’re thrilled to announce Suno’s next chapter: a $400M Series D at a $5.4B valuation! 🚀
Our mission has always been simple: more people should get to experience the joy of making music. Huge thanks to our incredible community and investors for building alongside us.

Big news for @conductor_build!

We've raised a $22m Series A from Spark and Matrix.

We raised this round from @ilyasu at Matrix, who also led our seed round and is joining our board, @nabeel at Spark, @ycombinator, and founders of Notion and Linear. We're grateful to be working with investors we trust and admire.

Here’s how we got here and where we’re going:

[Matrix @matrixvc]

Matrix is proud to be a founding host of Boston’s first-ever @Techweek_ , alongside partners like a16z. As a firm built by former founders and operators, we’re excited to support a week dedicated to the builders, technologists, and ideas shaping what’s next.
We’ll be hosting an event during the inaugural week and look forward to welcoming founders from across the ecosystem. Submissions to host events are now open: https://t.co/ziKijSlWdY #BOSTechWeek

Thrilled to work with the @boldvoiceapp team. Congrats @AnadaLakra @Ilyausorov

[Anada Lakra @AnadaLakra]

Excited to announce our series A fundraise at @boldvoiceapp. The work continues!

[Patrick Malatack @malatack]

Really excited to be working with @deepsinglak and the team at @finichatAI. If you want AI enabled customer support that actually works check them out https://t.co/IFkHALWHIM

[Dana Stalder @dcstalder]

Another consumer experience being reimagined in the age of AI. Very excited about this deeply creative team, this product and this investment! @thecosmos @9th

[TJ Parker⚡️ @tjparker]

We built the thing everyone knows should exist but doesn’t.

[Ilya Sukhar @ilyasu]

Tristan and his team at dbt Labs have built a remarkable company and community. And they fit together with Fivetran like peanut butter and jelly. Onwards and upwards, together!

[Ilya Sukhar @ilyasu]

Every digital artifact can be expressed as code and code gen is coming to every digital product.

Preston and Eitan are building lightning fast models and infra for devs implementing coding agents.

Privileged to work with this supremely talented team alongside friends at a16z!

[Stan Reiss @stanreiss]

Ciena just announced it is acquiring our portfolio company Nubis Communications. Great news for both! Ciena gains an exceptional team, phenomenal products, and a breakthrough technology portfolio—and the Nubis team will turbocharge their journey with Ciena’s resources. Congratulations! https://t.co/bcZ81x6QsA

[Ilya Sukhar @ilyasu]

Agentic interfaces really need domain specific primitives and integrations to reliably nail outcomes for non-technical users and go beyond demoware. We're going to see AI-first startups slogging to backfill those as aggressive pre-AI mid stage companies layer AI interfaces on top of years of deep engagement with customers.

Parabola is a perfect example of the latter and their new AI phase is here!

[Stan Reiss @stanreiss]

Big congrats and well earned @saileshtalks and @bayasystems team!

[Doug Safreno @dougsafreno]

Big news today: @GentraceAI raised our $8M Series A led by @MatrixVC.

We’re celebrating by launching Experiments, the first collaborative testing environment for LLM product development.

[Ilya Sukhar @ilyasu]

JJ and I met at FB. When he sold his first startup, we had a conversation about money that I’ve had with dozens of acquired founders. It goes something like: “No, the wealth managers don’t have any big secrets. Just buy indices and chill.”

JJ’s second startup turns that notion into a product for everyone: customizable index investing, tax loss harvesting, and – importantly – no fees! Excited to be involved as both investor and customer.
