Uncork Capital

Uncork Capital is a San Francisco-based seed-stage venture firm founded in 2009, originally operating as SoftTech VC before rebranding in 2021. The firm's managing partners — Andy McLoughlin, Jeff Clavier, Amy Saper, Susan Liu, and Tripp Jones — have collectively backed more than 290 companies across seven institutional funds. Understanding NRR and why top quartile exceeds 120% is valuable for any founder.

Uncork's investment thesis is captured by their tagline: 'First to believe, still beside them.' The firm specializes in being the first institutional check for exceptional founders building AI-native companies, developer tooling, B2B SaaS, and marketplace businesses. The firm writes seed checks typically between $1.5M–$3M, targeting 12–15% initial ownership, with reserved capital for Series A and later follow-ons in portfolio winners.

Unlike firms that chase the same crowded deals at Series A, Uncork prefers to establish deep partnership relationships at the earliest possible stage — often before product-market fit is fully established. This is where the firm's partners believe their capital and networks have the most outsized impact.

The firm's portfolio spans category-defining companies including SendGrid (IPO, acquired by Twilio for $2B+), Fitbit (IPO, acquired by Google for $2.1B), Poshmark (IPO), Postmates (acquired by Uber for $2.65B), and Groq (AI compute). More recent AI-native bets include GPTZero, Ivo, and Numeral. Uncork has generated over $60B in exit enterprise value across its portfolio.

For founders seeking seed capital, understanding Uncork's approach — what they look for, how they work with portfolio companies, and how to position your pitch — is essential for building a lasting partnership rather than just securing a check.

Uncork Capital's investing philosophy centers on conviction at the earliest stage. The firm's partners describe their approach as backing 'exceptional founders from zero' — the moment when institutional capital is scarcest and a partner's belief can be transformative. Understanding unit economics and LTV:CAC is valuable for any founder.

The firm's sector focus spans six primary verticals: B2B Applications, Developer Tooling and Infrastructure, Security, Consumer and Marketplaces, Frontier Tech and Hardware, and AI/ML. Within these, Uncork looks for companies creating leverage, unlocking scale, and pushing industries forward — particularly AI-native businesses where the technology is core to the value proposition, not a feature layer.

Uncork writes seed checks typically between $1.5M–$3M, targeting 12–15% initial ownership. The firm occasionally invests at the pre-seed stage for exceptional founders and reserves significant capital for Series A and later rounds in portfolio winners. The firm leads or co-leads the majority of its seed investments.

The firm's investment approach is thesis-driven but not theme-limited. Uncork has demonstrated conviction across economic cycles, from cloud infrastructure (SendGrid) to consumer marketplaces (Postmates) to AI compute (Groq). The consistent thread is category-defining potential paired with founders who have a deeply earned unfair advantage.

Uncork runs an annual portfolio summit that brings together founders from across its portfolio, creating a network effect that drives collaboration, hiring, and follow-on investor introductions. This community of builders is a core part of what makes Uncork a differentiated partner — not just capital, but a network.

The firm's relatively concentrated portfolio (compared to seed funds writing 50+ checks per year) allows partners to provide meaningful support to each company — strategic advice, customer introductions, hiring references, and operational guidance.

Uncork has maintained an active investment pace through 2024 and 2025, with notable activity in AI-native infrastructure, developer tools, and vertical SaaS. The firm's recent portfolio includes companies like GPTZero (AI detection for content authenticity), Ivo (AI-powered contract review), Numeral (sales tax automation), and Wrapbook (media production financial management). Understanding EBITDA multiples in growth-stage valuation is valuable for any founder.

The firm continues to lead seed rounds in AI-native companies, reflecting its conviction that the most transformative businesses are being founded now — with AI as a core architectural decision rather than a wrapper around legacy software. Uncork's partners can often move from first meeting to term sheet in 2–3 weeks for companies that fit the thesis clearly.

In addition to new investments, Uncork has been active in supporting its existing portfolio through follow-on rounds. The firm's reserved capital for Series A+ investments means they can continue to partner with winning companies rather than being forced to sell or rely on new investors.

Uncork's 2024 and 2025 portfolio activity reflects the broader market shift toward AI-native everything — the firm has participated in rounds for companies building AI-powered compliance, AI-driven sales tooling, and AI-first vertical SaaS. The partners remain sector-agnostic within technology, focused instead on category design and founding team quality.

Market conditions have led Uncork to be more rigorous on due diligence, but the firm's willingness to invest early and decisively hasn't wavered for the right founders. The firm remains committed to writing first checks and leading rounds, not following other investors into crowded deals.

Uncork's exit track record is one of the strongest in seed-stage venture. SendGrid — the email infrastructure company — went public in 2017 (NYSE: SEND) and was later acquired by Twilio for over $2B. Uncork's seed investment in SendGrid before email infrastructure became a recognized category illustrates the firm's pattern of early conviction.

Fitbit (wearables) went public and was acquired by Google for $2.1B. Postmates (local delivery marketplace) was acquired by Uber for $2.65B in 2020. Poshmark (fashion resale marketplace) went public in 2021. Groq, the AI compute company, was acquired by a strategic acquirer. Mint (personal finance) was acquired by Intuit.

On the growth side, LaunchDarkly (feature management for software teams) has become foundational infrastructure for thousands of engineering teams. Tailscale (networking software) has built a category-defining product in the zero-trust networking space. Human Interest (retirement benefits for SMBs) and Carrot Fertility have scaled into large category leaders.

More recent vintage holdings include Gamma (AI-powered presentation software), ClassDojo (education communication platform), Hallow (Catholic prayer app), Coder (cloud development environments), Loft Orbital (space infrastructure), and Anything (no-code platform). In the AI wave, GPTZero, Ivo, and Numeral represent Uncork's conviction in the next generation of category-defining companies.

Uncork's portfolio is spread across B2B SaaS, developer infrastructure, fintech, insurtech, marketplaces, and AI — unified by large operational complexity in addressable markets and founders with deep domain expertise.

Uncork evaluates investments based on three primary dimensions: founding team quality, market opportunity, and unfair advantage. The firm places the heaviest weight on the founding team — looking for founders with obsessive domain expertise, a clear vision for how their category will evolve, and the ability to attract world-class talent.

Within the team assessment, Uncork particularly values what they call 'unfair advantage' — a deep network, novel data insight, technical differentiation, or operational experience that creates a defensible moat. This is not a commodity; it is something the founder earned through years of work in the space, not something that can be replicated by reading a trend report.

Market opportunity matters, but Uncork is not looking for large TAM alone. The firm seeks markets that are large enough to build a significant business and where the current solution is so inadequate that a founder with deep expertise can create a step-change improvement. Incremental improvements rarely make it past the partner meeting.

Business model quality has become increasingly important in recent vintage investments. Uncork looks for companies with clear paths to strong unit economics — not necessarily profitability at the seed stage, but a demonstrable mechanism for creating economic value that scales with customers. Annual recurring revenue metrics, gross margin profile, and customer acquisition cost dynamics are all scrutinize

Competitive positioning is evaluated carefully. The firm looks for companies with moats that strengthen over time — proprietary technology, network effects, exclusive data, or ecosystem lock-in. Once a company demonstrates clear differentiation in a large market, Uncork wants to be the first to believe in that differentiation.

The common thread across successful Uncork investments is a founder who knows something true about their market that the rest of the world hasn't fully priced in yet — and has the conviction to build toward it before it's obvious.

The most effective path to Uncork is a warm introduction from a portfolio founder, another investor who has worked with the firm, or a respected member of the entrepreneurial community. Uncork's partners take these introductions seriously because the signal from a trusted peer reduces the noise of a cold deck.

If a warm introduction isn't available, cold outreach through pitches@uncorkcapital.com is a legitimate channel. The firm reviews every submission, but the volume is high — a compelling articulation of why this company fits Uncork's specific thesis, not just why it's a good company, is essential for standing out.

When cold outreach, focus on specificity: which vertical, which customer pain, what the unfair advantage is, and why Uncork specifically. Generic 'we're a great SaaS company' emails get filtered quickly. The firm looks for founders who have done the work to understand what makes Uncork the right partner at this stage.

Before the meeting, prepare to discuss the big picture — not just the product, but the category design. Uncork's partners want to understand why this market is being transformed, what your unfair advantage is, and how you think about the long-term evolution of the space. Come with a clear ask and know your numbers cold.

Follow-up after a meeting should be substantive, not just polite. Send meaningful updates on traction, team progress, or product milestones — not generic 'we're still working on it' notes. Uncork's partners value founders who move fast and have something real to share.

Building a relationship with Uncork outside of a fundraise is also valuable. Founders who engage with Uncork's portfolio summit, connect with portfolio founders, or participate in the firm's community build long-term credibility with the partners — even if the timing isn't right for an investment at first contact.

Seed-stage companies that present clear, investor-ready financials consistently outperform in fundraising processes. Uncork's partners will dig into your unit economics, burn rate, and path to profitability — founders who can speak fluently about these topics signal operational maturity that the firm wants to back.

Common gaps in early-stage financial preparation include conflating revenue with ARR benchmarks, lacking clarity on gross margin by segment, not modeling customer acquisition cost and lifetime value correctly, and having no coherent narrative for how the next round connects to the current financial position.

Working with a fractional CFO can significantly improve your fundraising readiness. Professional financial guidance helps you build accurate projections, prepare investor-ready financials, and confidently answer due diligence questions — including the hard scenarios that Uncork's partners will inevitably raise.

Financial projections should reflect deep operational understanding, not optimistic hockey-stick charts. Uncork's partners will challenge assumptions and probe for evidence — founders who can defend their numbers with data from their own business have a significant advantage over those relying on market research alone.

Understanding your KPIs is table stakes when pitching Uncork. The firm will want to see that you track the metrics that actually drive your business — not vanity metrics — and that you can explain trends with operational causes, not just the numbers themselves.
