Founded in 2021 by Leshika Samarasinghe and Ethan Yeh, the $25 million debut fund has quickly established itself as a key backer of mission-driven founders who see purpose and profit as inseparable.

Unlike traditional enterprise SaaS VCs, Twine focuses on companies using data, AI, and software infrastructure to solve some of the most pressing challenges in healthcare systems and climate-impacted industries. The firm's partnership with Foundry's meta-network of co-investing venture funds gives portfolio companies access to a broader ecosystem of support and follow-on capital.

This guide covers Twine Ventures's actual investment thesis, real portfolio companies, check size expectations, and practical advice for founders considering applying. Whether you're building in health tech, climate tech, or fintech infrastructure, understanding Twine's specific criteria will help you determine if they're the right fit for your fundraising journey.

Twine has demonstrated a particular commitment to backing women and BIPOC founders, with the majority of their portfolio companies led by underrepresented founders. This focus aligns with their thesis that diverse teams often bring unique perspectives to complex problems in healthcare and climate—sectors where incumbents have been slow to innovate.

Twine Ventures operates from a clearly defined thesis: they partner with early-stage founders for whom purpose and profit are inextricably linked. The firm invests in audacious teams building enabling technologies—data, AI, and software infrastructure—that accelerate transformation in two primary domains: healthcare systems and climate-impacted industries. Understanding net revenue retention benchmarks is valuable for any founder.

The $25 million fund targets seed-stage investments with initial checks of $500,000 to $750,000, with the ability to invest $250,000 to $1M total across a company's early growth. Twine prefers to be the first institutional investor, entering at the concept or pre-seed stage when founders need capital to prove their thesis.

Within healthcare, Twine looks for companies modernizing how care is delivered, diagnosed, and paid for. This includes root-cause medicine platforms, prescription drug affordability solutions, specialty lab testing, and digital health infrastructure. In climate and industrials, the firm invests in technologies addressing electrification, carbon management, and industrial efficiency.

The fintech and data infrastructure vertical focuses on companies building the underlying tools that enable better financial decision-making—ranging from API-driven financial software to data orchestration platforms. These companies often serve as infrastructure for other enterprises, creating network effects and defensible moats.

Twine evaluates investments based on founder clarity about the problem they're solving, evidence of technical differentiation, and early signals of product-market fit. The firm's partnership with Foundry provides portfolio companies with access to a meta-network of over 40 co-investing venture funds, extending the firm's reach beyond its own check size.

Since launching in 2021, Twine Ventures has deployed its $25 million fund across more than 30 portfolio companies. The firm maintains an active investment pace, making 8-12 new investments per year from its debut fund. Recent activity shows continued focus on healthcare and climate, with several investments in AI-enabled drug discovery and clean energy infrastructure. Understanding NRR and why top quartile exceeds 120% is valuable for any founder.

Twine's deal flow comes primarily through warm introductions from the Foundry network, portfolio company referrals, and founder networks in the Bay Area. The firm's first-check positioning gives it access to opportunities before larger funds have a chance to evaluate them.

Follow-on investment is available for portfolio companies that hit milestones, though Twine typically participates in subsequent rounds alongside other institutional investors. The firm's partnership with Foundry creates a natural funnel for companies that graduate to Series A, as the meta-network co-invests in promisingTwine portfolio companies at later stages.

Market conditions have led Twine to maintain discipline in its investment approach, but the fund remains actively deploying. The first-check strategy positions Twine well in slower markets, as many seed-stage founders prefer capital from investors who can move quickly without extensive committee review.

Twine Ventures's portfolio spans healthcare, climate tech, and fintech, with several companies gaining significant traction. Understanding what Twine looks for in portfolio companies helps founders align their pitch with the firm's values.

Rupa Health has become a flagship investment, providing specialty lab testing for root-cause medicine practitioners. The platform enables functional medicine doctors to order comprehensive lab panels and interpret results within a unified workflow, addressing a real pain point in integrative healthcare.

Waltz Health, which was acquired during Twine's holding period, focused on prescription drug affordability—directly addressing the pricing opacity that plagues the pharmaceutical industry. The exit demonstrated Twine's ability to identify companies tackling systemic healthcare costs.

Alpha Grid invests in EV charging infrastructure management, helping commercial property owners deploy and operate charging networks. As fleet electrification accelerates, Alpha Grid's software addresses the operational complexity of managing distributed charging assets.

Apella Technology is modernizing surgical scheduling and peer collaboration for surgical teams. The platform addresses communication breakdowns that contribute to millions of dollars in preventable surgical complications annually.

Other notable holdings include Teiko Bio (computational immunology), Endeavor Health (health system innovation), Waymark (Medicaid care delivery), Alaffia (health equity), and Colla Health (healthcare financial reconciliation). In climate, Nectar Climate and Covalent Technologies represent Twine's bet on next-generation carbon and industrial technologies.

Twine evaluates potential investments based on several key criteria aligned with their purpose-driven thesis. The firm places exceptional founders at the center of their evaluation, looking for entrepreneurs with deep domain expertise, proven execution ability, and a clear vision for systemic change.

Founder-market fit is critical. Twine wants to see that founders have direct experience with the problem they're solving—whether that's a physician frustrated by clinical workflows or an engineer who has worked in energy infrastructure. Academic credentials matter less than demonstrated domain insight.

Technical differentiation sets Twine portfolio companies apart. The firm looks for companies with proprietary data assets, unique algorithmic advantages, or novel approaches to old problems. In healthcare especially, regulatory moats and clinical evidence can serve as competitive protection.

Market opportunity must be large and growing. Twine typically evaluates healthcare markets exceeding $1B in total addressable opportunity, though climate and fintech markets often have different dynamics. The firm wants to see a clear path to $100M+ ARR benchmarks potential.

Evidence of product-market fit strengthens any application. Early traction can take many forms: revenue, engaged users, clinical outcomes data, or letters of intent from enterprise customers. Twine understands that early-stage companies show traction differently and evaluates accordingly.

Values alignment is what truly differentiates Twine from other seed funds. The firm explicitly seeks founders building companies where purpose and profit reinforce each other—where addressing a social need creates sustainable competitive advantage.

Getting on Twine Ventures's radar requires a strategic approach. The firm relies heavily on warm introductions from the Foundry network, portfolio founders, and trusted advisors in the entrepreneurial community. Building relationships before pitching significantly improves your chances of securing a meeting.

The Foundry meta-network is Twine's primary deal sourcing channel. Founders who have connections to other Foundry fund managers or portfolio companies should leverage those relationships for warm introductions. The networked approach means your reputation within the venture community matters.

Cold outreach through Twine's website is possible but must stand out. Your pitch should immediately communicate what problem you're solving, why you're the right team to solve it, and why Twine specifically should care. Generic enterprise SaaS pitches won't resonate—Twine wants to see healthcare, climate, or fintech infrastructure focus.

When preparing for your meeting with Twine, be ready to discuss your thesis in depth. The firm will probe your understanding of the problem, your proposed solution, early evidence of traction, and your path to scale. Expect questions about why now, why you, and why Twine.

Follow-up after your initial meeting should be consistent but not aggressive. Twine typically makes investment decisions within 3-5 weeks of an initial meeting, so sending brief updates on milestones is appropriate. Avoid daily check-ins that may signal impatience or lack of conviction.

While Twine Ventures invests at the seed stage, they expect founders to have a solid command of their unit economics and capital efficiency. Understanding your burn rate, runway, and path to breakeven demonstrates operational maturity that Twine looks for in founding teams.

For healthcare companies especially, clinical evidence costs money. Founders should be prepared to discuss their funding runway in the context of regulatory timelines, clinical trial costs, or enterprise sales cycles. Twine understands that healthcare and climate startups often have longer paths to revenue.
