Seattle’s TheFounderVC Launches $5M AI-First Fund, Betting Big on Vertical AI Startups

By [Your Name] | March 25, 2026

SEATTLE — In a bold move that signals the next wave of AI innovation, TheFounderVC (TFVC), a newly formed early-stage venture fund headquartered in both Seattle and San Francisco, officially launched its inaugural $5 million fund on Tuesday. The firm is zeroing in on what it calls “vertical AI” — startups building industry-specific AI applications that go beyond generic large language models to deliver deeply tailored, workflow-integrated solutions for niche markets.

The announcement comes at a time when AI investment is reaching a fever pitch, but TFVC is carving out a unique niche by targeting startups that combine proprietary data advantages with highly personalized user experiences. According to founding partner Mia Lewin, the biggest opportunities in AI lie not in broad, horizontal applications, but in vertical solutions that solve specific industry pain points with precision and scalability.

Meet the Team: Silicon Valley and Seattle Veterans Unite

The fund’s leadership team is a powerhouse of entrepreneurial and operational experience, blending deep tech expertise with a track record of building and scaling companies.

• Mia Lewin (Seattle): A three-time founder, Lewin previously launched StyleGenome, an AI-driven fashion tech startup acquired by Wayfair. Her background in consumer tech and AI gives her a unique lens on vertical opportunities.

• Paul Longhenry (San Francisco): A seasoned investor and former executive at Tapjoy, Pinpoint Predictive, and Bolt, Longhenry brings decades of experience in scaling tech companies and identifying breakout trends.

• Shail Kaveti (San Francisco): A former Wayfair executive and Amazon senior manager, Kaveti is also an angel investor in Perplexity, the AI-powered search engine. His operational and investment acumen adds a strategic edge to the team.

• Jay Bartot (Seattle): A serial entrepreneur in the Seattle tech scene, Bartot previously served as managing director at Madrona Venture Labs and has founded multiple startups in the region.

The team’s bicoastal presence reflects TFVC’s dual focus on Seattle’s deep tech talent pool and San Francisco’s venture capital ecosystem.

Vertical AI: The Next Frontier

TFVC’s thesis is simple yet ambitious: the future of AI lies in vertical applications that combine structural data advantages with workflow-native products. In a LinkedIn post announcing the fund, Lewin wrote, “We back visionary founders who combine deep domain expertise with an AI-native vision to build category leaders of tomorrow.”

This approach is already resonating with investors. TFVC has secured approximately 60 limited partners for its debut fund, signaling strong confidence in its strategy. The firm plans to make 25 to 30 investments, with initial check sizes ranging from $100,000 to $250,000 at the pre-seed and seed stages.

Seattle’s AI Ecosystem Takes Center Stage

Despite its dual headquarters, TFVC has deep roots in Seattle. Five of the fund’s seven portfolio companies have at least one founder based in the Emerald City, underscoring the region’s growing reputation as a hub for AI innovation.

Among its portfolio highlights:

• Potato: This startup is revolutionizing scientific research by automating science experiments, a move that could drastically reduce the time and cost of R&D.

• Liminary: An AI-powered knowledge storage company that helps organizations capture, organize, and retrieve critical information with unprecedented efficiency.

• Planette: Leveraging AI to help businesses plan for weather and climate risks, Planette recently raised $2.4 million to expand its AI-boosted weather and climate prediction technology.

• Ridge AI: A data analytics dashboard startup that simplifies complex data visualization for businesses.

• Daydream: A fashion AI startup that uses machine learning to personalize shopping experiences.

• Catchouse: A home-buying company that streamlines the real estate transaction process with AI-driven insights.

These companies exemplify TFVC’s focus on vertical AI, each addressing a specific industry challenge with tailored AI solutions.

Why Vertical AI Now?

The timing of TFVC’s launch is no accident. As AI models become increasingly commoditized, the real value is shifting to applications that can leverage proprietary data and domain expertise. “The biggest opportunities in AI are in applications that combine structural data advantages with workflow-native products and highly personalized user experiences,” Lewin explained.

This strategy aligns with broader trends in the tech industry. Investors and entrepreneurs alike are recognizing that the next wave of AI innovation will come not from building bigger models, but from creating smarter, more specialized applications that solve real-world problems.

A New Chapter for Seattle’s Tech Scene

TFVC’s launch is a significant milestone for Seattle’s tech ecosystem, which has long been overshadowed by Silicon Valley. With its focus on vertical AI and its deep ties to the region, TFVC is poised to become a key player in shaping the future of AI innovation.

As the fund begins deploying capital, all eyes will be on its portfolio companies to see if they can deliver on the promise of vertical AI. If successful, TFVC could not only generate strong returns for its investors but also cement Seattle’s status as a leading hub for AI-driven entrepreneurship.
