A group of RNA veterans is launching a new startup aimed at getting **RNA-interfering (RNAi) molecules** into the brain to silence the genes that cause neurodegenerative diseases. Called **Aerska**, the Dublin-headquartered firm has raised **$21 million in seed funding**, with plans to treat Alzheimer’s and Parkinson’s diseases.

"It started in a pub in Ireland, like all good ideas," says CEO Jack O’Meara. It was late 2024, and O’Meara had just stepped away from Ochre Bio, a startup he’d cofounded to make RNAi drugs to treat liver diseases. O’Meara had for years wanted to use RNAi to tackle brain disorders, but he’d run into a series of technical challenges: first, getting RNAi molecules across the **blood-brain barrier**, then getting them to distribute throughout the brain’s 400 miles of capillaries instead of settling in one spot.

Meetings in bars and restaurants in Ireland and Boston sparked the beginnings of Aerska. O’Meara reconnected with Stuart Milstein, a former Alnylam Pharmaceuticals scientist who’d helped lead neuroscience efforts at the RNAi-focused firm, and David Coughlan, another Ochre Bio veteran, to help refine his ideas. O’Meara then reached out to some of his former investors. It didn’t take long for Aerska to get off the ground: the startup emerged from stealth on Wednesday with 15 employees spread across Ireland, the UK, and the US, including Milstein as cofounder and Coughlan as head of early development.

Aerska’s key technology is what O’Meara and his team have termed **"brain shuttles"**.

The **blood-brain barrier strictly controls what molecules can pass** into the brain, and the endothelial cells that make up the barrier have receptors that determine which molecules, like iron and glucose, they can safely allow across the wall. "We basically try and trick the blood-brain barrier into thinking your RNA is something it wants to internalize," O’Meara says.

To do that, the Aerska team attaches **transferrin-receptor-targeting antibodies** to the interfering RNA molecules, making antibody-oligonucleotide conjugates. The shuttle binds to that receptor, "and then the payload gets pulled across [the blood-brain barrier], in concert with the antibody or peptide that’s used to conjugate the RNA." From there, the RNAi medicine would—in theory—be distributed throughout the brain through its bloodstream.

O’Meara and his team are hoping to avoid spinal injections and intravenous infusions, instead engineering for a more patient-friendly approach: **under-the-skin injections**, the same way medicines like semaglutide are administered. But that’s still a few years away. O’Meara says Aerska is in conversation with potential licensing partners for technology that could speed up the startup’s preclinical work. The $21 million seed round will last a couple of years. After that, O’Meara will need to raise more money before Aerska can begin testing in humans.

O’Meara and his team intend to take a **precision medicine approach** to treating Alzheimer’s and Parkinson’s diseases. That is, they will likely try to find certain subpopulations that have a greater chance of responding to Aerska’s drug candidates.

"We’re looking for patient populations where we’re more confident in the biology and the target that we’re going for," O’Meara says. "If we could try to take some lessons learned from the oncology field, once you start to divide these diseases up into more tractable subdiseases, they get easier."

Toyota is aggressively seeking the next big innovations in **mobility**, **climate technology**, **AI**, and **industrial automation**. The automaker is backing this vision with a substantial **$1.5 billion in new capital**, aimed at investing in startups across their entire lifecycle—from the earliest seed stages through growth phases and into maturity.

## Toyota's Strategic Investment Moves

This week, Toyota unveiled two key initiatives that highlight its deepening commitment to the startup ecosystem. These efforts are closely tied to **Woven City**, a prototype city in Japan designed to nurture startups, which recently opened its doors.

- **Toyota Invention Partners Co.**: A new strategic investment subsidiary has been established with approximately **$670 million in capital**. This entity will focus on **Japan-based startups** and adopt a long-term approach, moving away from fixed investment periods typical of traditional funds.

- **Woven Capital's Second Fund**: The growth-stage venture arm launched a new **$800 million fund**, continuing its mission to support scaling companies.

George Kellerman, General Partner at Woven Capital, described Toyota Invention Partners as a "bookend" to Toyota's other investment arms. It handles the "**zero to one**" stage, while **Toyota Ventures** manages early-stage investments, and **Woven Capital** focuses on growth stages. Importantly, Toyota Invention Partners may stick with startups through all phases, potentially integrating successful ventures into Toyota's balance sheet.

## A Unified Investment Strategy

Kellerman emphasized that these announcements reflect Toyota's strong belief in startup-driven innovation. With over **$3 billion committed** across various funds, Toyota is "leaning in" to meet the evolving needs of founders and the market.

This strategy is already in action.

## Building a Startup on Her Own Terms

In Barcelona, Kumar **founded her own startup**, applying the skills she'd honed at major tech companies but with a completely different mindset. Her new venture focuses on creating meaningful impact rather than chasing venture capital or rapid scale.

"Starting my own company after years in big tech felt like reclaiming my power," she explains. "I'm building something that aligns with my values, not just corporate metrics."

## The Happiness Equation

Kumar's story highlights a growing trend among tech professionals: **the search for work-life balance and authentic fulfillment**. Her experience shows that sometimes the most career-defining moments come from stepping away from traditional success paths.

**Moving to Barcelona provided more than just scenic views**—it offered a new perspective on what truly matters in life and career. The slower pace, rich culture, and emphasis on living rather than just working have transformed Kumar's approach to entrepreneurship.

After Steph Kumar was laid off from Twitter, she realized how her career shaped her identity. She redefined success by founding a startup and moving to Barcelona.
