Rostra Capital Research
Overview
Rostra Capital (LLC) is a single-family office based in Harrison, New Jersey, founded in 2013 by Jorge Tabuas. Operating as a boutique principal investment vehicle, it manages assets across venture capital and growth equity stage businesses. The firm is small by design — a solo GP structure — with Jorge Tabuas serving as both Founder and CEO/Senior Managing Director. Despite its small size, the firm brings significant capital markets depth: Tabuas has over 20 years of experience across principal investing, investment banking, and financial advisory, having raised more than $1 billion in capital through IPOs, Secondaries, SPACs, PIPEs, and private transactions.
Investment Thesis
Rostra Capital's thesis centers on identifying undervalued, high-potential opportunities across the technology, healthcare, energy, and real estate sectors, with a primary geographic emphasis on North America but extending to South America, Europe (Iberian markets), Africa (Angola and Mozambique), and Australasia. The firm targets startups and micro-cap companies at the intersection of innovation and market disruption, taking an active role in portfolio companies to leverage its capital, experience, and strategic network.
Tabuas describes his investment philosophy as seeking opportunities in "innovative and emerging sectors" including fintech, blockchain, healthcare technology, and energy, with particular interest in companies that serve underserved or overlooked market segments. His core toolkit includes venture debt, subordinated debt, public equity offerings, and special situations investing — reflecting a hybrid approach that blends traditional VC with structured finance.
Stage Focus
Rostra Capital invests across a broad stage spectrum:
- Seed / Pre-Seed: Early-stage startups with innovative product concepts (e.g., Accern seed round in 2017)
- Growth Equity / Venture: Later venture and growth-stage companies (e.g., LevelField Financial)
The firm does not appear to limit itself to a single stage and is comfortable leading or co-leading early rounds.
Check Size
Given the solo GP / family office structure and known participation in a $1.25M seed round (Accern), check sizes are estimated in the range of $100K–$750K for seed/early stage investments. For growth equity, the firm may deploy larger amounts through structured instruments (venture debt, PIPEs). Specific check-size disclosures are not publicly available.
Recent Activity
Rostra Capital appears to have made two publicly documented investments:
-
Accern (May 2017): Co-led a $1.25M seed round for Accern, a New York City-based fintech startup using AI to monitor 300M+ websites for curated breaking financial news. Other investors included VYL LLC, Gurtin Ventures, 26 Ventures, Belmont Capital, and Affinity Investment Group. Accern later went on to raise $2.1M (Pre-Series A) and $20M (Series B in 2022).
-
LevelField Financial (circa 2022): Invested in LevelField Financial, a crypto-friendly banking platform that has raised $25.8M in total. LevelField allows customers to bank with both traditional dollars and digital assets, and completed its first acquisition in 2022 while raising a $50M round.
The firm's investment pace has been selective — approximately 2 publicly disclosed deals over 10+ years — consistent with a family office model focused on conviction-based, high-quality deal selection rather than volume.
Portfolio Highlights
- Accern (accern.com): AI-powered financial news analytics platform. Grew from $1.25M seed to $20M Series B. Monitors 1 billion+ news sources for finance industry clients.
- LevelField Financial (levelfield.us): Crypto-friendly banking platform with $25.8M raised. Banking platform that bridges traditional banking with digital assets.

Decision Process
As a solo GP / family office structure, investment decisions are made by Jorge Tabuas directly. The firm does not appear to have a formal investment committee. This enables fast decision-making but limits deployment capacity compared to institutional funds.
Geographic Focus
- Primary: North America (US, with particular focus on Iberian-connected markets)
- Secondary: South America, Europe (Iberian Peninsula), Africa (Angola, Mozambique), Australasia
Anti-Thesis
Based on the firm's structure and disclosed thesis, Rostra Capital does not appear to target:
- Consumer applications with no enterprise component
- Pure hardware/manufacturing plays
- Large-cap or late-stage private equity deals
Notes
The URL originally associated with this firm (rostra.com) belongs to Rostra Accessories, Inc. (an automotive aftermarket manufacturer subsidiary of VOXX International). The actual Rostra Capital VC firm website is rostracapital.com. The firm appears to have limited web presence, which is consistent with a single-family-office model that operates through direct relationships rather than inbound deal flow.
