Diogo Mónica

Background

Diogo Mónica is a General Partner at Haun Ventures and co-founder and Executive Chairman of Anchorage Digital, the first federally chartered crypto-native bank in the United States ¹².

Born in California and raised in Portugal, Mónica completed his undergraduate and master’s degrees in communication networks engineering at Instituto Superior Técnico (IST), University of Lisbon, and subsequently earned a Ph.D. in computer science (network security) from the same institution ³¹. At IST he developed research on usable security that he presented at a conference in the United States, drawing offers from Google and Facebook — both of which he declined ⁴.

Instead, Mónica joined Square (now Block) around 2011 as one of its early security engineers. At Square he built the infrastructure security platform that now processes over $200 billion in annualized gross payment volume, and co-invented the Square card reader alongside Jack Dorsey, holding a patent on that invention ³⁵. It was at Square that he met Nathan McCauley, who would become his Anchorage co-founder ⁵.

In 2015, Mónica left Square to join Docker as Security Lead, alongside McCauley. At Docker he helped secure container infrastructure used by global banks, governments, and the three largest cloud providers ¹³. He contributed to industry security standards, including the Notary project accepted by the Cloud Native Computing Foundation, and served on the technical oversight board of the Open Container Initiative ¹.

In November 2017, Mónica and McCauley co-founded Anchorage Digital in San Francisco ⁵. Anchorage became the first and only federally chartered crypto-native bank, receiving its OCC charter in January 2021 ³. Mónica served as President until joining Haun Ventures, and remains Executive Chairman ². Fortune named him to its 40 Under 40 list in the Finance category in 2020 ⁶.

In October 2023, Mónica was appointed Chairman of the NEAR Foundation Council ⁷. He joined Haun Ventures as General Partner in March 2024, becoming the firm’s second GP alongside founder Katie Haun ². Haun described him publicly as a “perfect complement” to the existing team given his operational experience building and leading a multi-billion-dollar company ². In 2023 Mónica also relocated part-time to Portugal to work more closely with Anchorage’s substantial Portuguese engineering team ⁵.

Mónica has been an active angel investor throughout his career, self-reporting over 100 investments across crypto, security, AI, and consumer sectors prior to joining Haun Ventures ². He holds dozens of patents in cryptography, payments, and security, and chairs the IEEE Disruptive Innovations and Public Visibility committees ¹.

Stated Thesis

(Self-reported: These represent what Mónica says publicly about his investment focus. See Inferred Thesis for analysis of actual behavior.)

Mónica has described his move to Haun Ventures in terms of professionalizing what had been a personal investing practice: “I’ve invested in over 100 companies as an angel investor, and now want to professionalize what’s been a side hustle” ².

He focuses on companies with strong technical founders and exceptional founder-market fit, writing on LinkedIn: “Founder-market fit beats passion alone” and advising founders to “pick a problem where your résumé reads like a cheat code” ⁸.

On stablecoins — a clear emphasis — Mónica and co-author Chris Ahn wrote that stablecoins represent “the clearest case of product-market fit within crypto” and that they enable “one global platform” and “near real-time settlement at negligible cost,” contrasting sharply with traditional batched settlement ⁹. He has described stablecoins as “at their core, programmable money” and sees investment opportunities in “solutions to the delicate balance of privacy and compliance” ⁹.

On onchain finance infrastructure, Mónica wrote that “the future of Onchain Finance is real-time,” investing in companies that provide real-time risk parameters to DeFi protocols ¹⁰.

On the opportunity for purpose-built banking for the innovation economy: “Companies building the future need financial infrastructure that doesn’t slow them down” ¹¹.

Inferred Thesis

Based on 9 verified investments with confirmed sources (7 Haun Ventures-era deals from 2024–2026, plus 2 confirmed angel investments from 2021). Note: Mónica self-reports 100+ angel investments; the vast majority lack public documentation, so this analysis is based on the verifiable subset.

Sector breakdown (9 verified investments): Stablecoin/payments infrastructure — BVNK, Ondo Finance (2 of 9, 22%); DeFi risk/infrastructure — Chaos Labs, Ondo Finance (overlapping; risk-management DeFi = ~2); banking/financial infrastructure — Erebor, Finisterra (2 of 9, 22%); crypto data/analytics — Messari (1 of 9, 11%); cybersecurity/AI — Simbian (1 of 9, 11%); fintech/financial guidance — Fruitful (1 of 9, 11%). Nearly all (8 of 9, 89%) investments are in crypto/fintech; the one exception (Simbian, AI security) reflects his pre-crypto security background.

Stage distribution (9 verified): Seed/angel — Ondo Finance 2021, Messari 2021, Fruitful 2022, Simbian 2024 (4 of 9, 44%). Series A — Chaos Labs 2024 (1 of 9, 11%). Series B — BVNK 2024, Erebor 2026 (2 of 9, 22%). Pre-seed — Finisterra 2025 (1 of 9, 11%). Unknown stage — Bitwise 2025 (1 of 9, 11%). Within Haun Ventures (post-March 2024), deals range from pre-seed ($3.75M Finisterra) to Series B ($50M BVNK). His stated check range of $1M–$100M with a $10M sweet spot aligns with this ¹².

Technical depth as filter: Every portfolio company in the verifiable set solves a technically complex problem at the intersection of cryptography, distributed systems, security, or financial infrastructure. There are no consumer-facing social apps or pure-media investments in the public record, despite his claimed 100+ angel portfolio spanning “crypto to security to AI to consumer.” The public record skews heavily toward infrastructure.

Founder profile preference: Mónica consistently writes about technical founder-market fit. His board posts (Erebor) are at companies founded by technical operators (Palmer Luckey, Anduril). His investment writeups emphasize founder credentials: Chaos Labs’ Omer Goldberg described as having “intense focus and vision”; Finisterra’s Henrique described as “a PhD in distributed systems with practical experience at Google and JPMorgan” ¹³¹⁰.

Co-investor patterns (Haun Ventures-era): Coinbase Ventures (BVNK), Tiger Global (BVNK), PayPal Ventures (Chaos Labs), Lightspeed (Chaos Labs), Bessemer (Chaos Labs), F-Prime Capital (Chaos Labs), Lightshift Capital (Finisterra), Founders Fund/Lux Capital (Erebor) ¹⁴¹⁵¹¹.

Geographic pattern: US-headquartered companies dominate, but with active interest in European technical teams — Finisterra Labs is a European founding team; Anchorage’s 20%+ Portuguese engineering presence reflects his own European ties ⁵¹³.

Not in the public record: Gaming/NFT, consumer social, L1 protocols, pure-play DeFi trading. His written thesis focuses squarely on financial infrastructure rather than the speculative or consumer-facing sides of crypto.

Sample size caveat: 9 verified investments represents a small fraction of his self-reported 100+ deals. The Haun Ventures-era portfolio (5 deals with sourced writeups) is the highest-confidence signal for his current investment focus.

Portfolio

Note: Mónica self-reports 100+ total investments as an angel investor ². Only 9 could be independently verified from press sources. The table likely represents under 10% of his total investment history.
