CityRock Venture Partners
CityRock Venture Partners operates as the Series A-and-beyond growth equity arm within the H/L Ventures ecosystem, which Oliver Libby launched in 2009. Built on the thesis that founders need daily, embedded support rather than passive capital, the broader platform started as H/L Studio — a company-building engine designed to co-create ventures from ideation through post-seed. The firm has expanded its architecture into four specialized arms: the flagship H/L Studio, CityRock Venture Partners for growth-stage equity, CityRock Private Credit for flexible debt solutions, and H/L Strategies, which advises corporate leadership teams on growth execution. The growth equity strategy targets companies both inside and outside the studio pipeline, deploying capital at Series A and later stages. The firm seeks large, fast-growing markets and backs teams where technology improves outcomes for people or the planet. Active involvement defines the model — the firm claims near-daily engagement with each portfolio company, providing operational specialists, strategic guidance, and network leverage. The credit arm offers an alternative to dilution-heavy equity rounds, extending flexible capital that preserves founder ownership. While specific portfolio names and fund sizes remain undisclosed, the platform's structure suggests a concentrated portfolio with deep operational entanglement rather than a diversified spray of minority checks across hundreds of startups. The combined H/L Ventures platform operates from its New York headquarters, with the CityRock Venture Partners and CityRock Private Credit vehicles functioning as dedicated capital pools for later-stage and credit-based investments. The firm fields a bench of operators and specialists who surface core needs early and shift between strategic counsel and tactical execution. The advisory arm, H/L Strategies, extends the platform's reach into corporate boardrooms, working directly with CEOs and leadership teams on growth strategy. No recent official announcements detail team size or specific fund closes, and the firm has not publicly disclosed its assets under management or aggregate deployment figures. The structural differentiator lies in CityRock's integration with an active venture studio rather than operating as a standalone growth fund. Most growth investors source deals from the open market; CityRock can originate investments from companies that H/L Studio helped build from inception, creating a proprietary sourcing funnel with deep institutional knowledge of founder-operators. When combined with an in-house private credit capability, the platform can sequence equity and debt for a single company, managing the full capital stack in a way that isolated growth funds cannot replicate.

Frequently asked questions
What is the relationship between CityRock Venture Partners and H/L Ventures?
CityRock Venture Partners is the growth equity arm within the H/L Ventures ecosystem, which also includes H/L Studio for company-building from inception to post-seed, CityRock Private Credit for flexible debt, and H/L Strategies for corporate advisory. Oliver Libby co-founded H/L Ventures in 2009, and the four arms operate under the same platform but with distinct mandates and stages of engagement. This architecture allows the firm to support companies across the full lifecycle — from napkin idea to scaled growth — with the appropriate capital type and operational intensity.
How does CityRock Venture Partners source its investments?
CityRock can source deals from the open market at Series A and beyond, but a significant differentiator is its access to companies built inside H/L Studio — the platform's early-stage company-building engine. Because the studio co-builds ventures alongside founders from inception, CityRock enters due diligence with deep institutional knowledge of the teams and business models. The firm describes near-daily engagement with portfolio companies, suggesting that the majority of sourcing comes through the platform's own network and operating relationships rather than a traditional outbound deal-funnel process.
Does CityRock only invest in companies from the H/L Studio?
No. While the firm benefits from a proprietary pipeline through H/L Studio, CityRock Venture Partners explicitly invests both inside and outside the studio at Series A and later stages. This dual mandate broadens the opportunity set beyond the companies the platform helped create, allowing the growth equity team to back external founding teams that fit the firm's sector and stage focus. The exact split between studio-originated and external deals has not been publicly disclosed.
What investment stages does CityRock Venture Partners target?
CityRock targets growth-stage investments at Series A and beyond. This sits downstream from H/L Studio, which focuses on company creation from ideation through post-seed. The platform's credit arm, CityRock Private Credit, offers debt solutions to companies within the ecosystem as an alternative to equity fundraises. Together, the arms cover the full capital-stack spectrum — early-stage equity, growth equity, and flexible credit — with each vehicle matching its structure to the company's maturity and capital needs.
Who runs investment decisions at CityRock Venture Partners?
Oliver Libby co-founded the H/L Ventures platform in 2009 and serves as a managing partner. The firm's website presents a unified leadership across the four arms, with no separate investment committee or dedicated CityRock managing partner currently disclosed. The hands-on, near-daily engagement model implies a centralized decision-making process driven by the founding partner and the platform's bench of operators, though the exact governance structure for investment approvals has not been publicly detailed.
