Standard Capital

About

Standard Capital is an AI-native venture capital firm founded in 2025 by Dalton Caldwell, Paul Buchheit, and Bryan Berg ¹. The firm is headquartered in San Francisco, California ². In September 2025, Standard Capital closed its inaugural Fund I at $425 million ³.

Dalton Caldwell previously served as Managing Partner at Y Combinator for over 12 years across 25 batches, advising more than 1,000 startups ⁴. He transitioned to Partner Emeritus at YC in June 2025 to co-found Standard Capital ⁵. Before YC, he co-founded and served as CEO of imeem (acquired by MySpace in 2009) and App.net ⁶.

Paul Buchheit is the creator of Gmail, built the AdSense prototype at Google, and coined the phrase “Don’t be evil” ⁷. He co-founded FriendFeed in 2007, which was acquired by Facebook in 2009 in what was Facebook’s largest acquisition at the time ⁷. He is also an early investor in OpenAI, DoorDash, Stripe, Airbnb, Reddit, Instacart, Rippling, and Perplexity ⁷. He serves as Partner Emeritus at Y Combinator ⁷.

Bryan Berg served as a Staff Engineer at Stripe, where he joined in 2014 and became the 10th most tenured employee, reporting to the CTO ⁸. He was the early Head of Security at Stripe, building internal security controls, datacenter infrastructure, and edge systems ⁸. He previously served as CTO at imeem and co-founded App.net with Caldwell ⁸.

The firm integrates AI into its core operations, including research, diligence, and memo writing ⁹. Standard Capital operates on a quarterly funding cycle, targeting approximately 5 investments per cycle for roughly 20 investments per year ^{1 10}.

Stated Thesis

Standard Capital publicly describes itself as “the AI-native Series A firm” built to “eliminate inefficiencies and misaligned incentives from traditional Series A fundraising by offering fast decisions, standardized terms, and founder-first structures” ^{1 9}.

The firm states it leads Series A rounds in “the top post-PMF companies” — startups that have already achieved product-market fit and are raising to scale, not to search ¹. Paul Buchheit has stated the firm looks for “great founders” working on ideas with “the potential to be worth $100bn” ¹⁰. Buchheit looks for products that “feel like magic” and backs technical founders who can build the product themselves ¹¹.

Standard Capital’s stated terms are distinctive: a minimum of 10% post-close equity for a lead investment (compared to the traditional 20-25% for Series A), with the option for founders to offer up to 20% if they want a larger lead ^{1 10}. The firm intentionally does not take board seats, instead organizing portfolio companies into quarterly in-person peer cohorts in San Francisco where founders collaborate and exchange insights ¹. Founders propose their own valuation and round size through an open application process that requires no warm introduction ¹. The firm publishes standardized investment documents and does not charge portfolio companies for legal fees ^{1 12}.

Inferred Thesis

Based on 6 verified investments from Standard Capital’s portfolio page ¹³, the following patterns emerge. Note: this is a small sample from a firm that launched in late 2025, so percentages should be interpreted with caution.

Sector breakdown (6 verified investments): - AI/ML infrastructure and tooling: 6 of 6 investments (100%) — every portfolio company is deeply AI-native or serves AI workflows - Developer tools: 3 of 6 (50%) — Trigger.dev (AI workflow platform), Sim.ai (agent workflow builder), Magic Patterns (AI design tool) - Data infrastructure: 1 of 6 (17%) — Artie (real-time data streaming) - Fintech/vertical SaaS: 1 of 6 (17%) — Concourse (AI agents for finance teams) - QA/testing: 1 of 6 (17%) — Momentic (AI test automation)

Stage distribution: 6 of 6 investments (100%) are Series A rounds, consistent with the firm’s stated exclusive Series A focus.

Check size range: $6M to $16M across the 6 investments, with a median of $12M. The full portfolio totals $68M deployed across 6 companies ¹³.

Geographic patterns: The firm holds quarterly meetings in San Francisco but does not appear to require portfolio companies to be Bay Area-based ¹.

Y Combinator connection: All 6 portfolio companies appear to be YC alumni or have YC participation in their rounds ^{14 15 16 17 18}, reflecting the partners’ deep YC network. This is a strong pattern not explicitly stated in their thesis.

Co-investor patterns: Y Combinator appears in all 6 rounds. Other recurring co-investors include SV Angel, Pioneer Fund, and Pathlight Ventures.

Notable alignment with stated thesis: The firm’s actual behavior closely matches its stated thesis in this early sample: exclusively Series A, post-PMF companies, and AI-focused. The strong YC alumni bias is the most notable unstated pattern.

What Founders Say

Trigger.dev noted in their Series A announcement that Standard Capital is “a new Series A firm led by Dalton Caldwell, the longest-serving Y Combinator partner, Paul Buchheit, and Bryan Berg” and stated they were “excited to be part of the first cycle from Standard Capital’s inaugural fund” ¹⁷.

Standard Capital closed the Momentic deal in just two weeks from initial application to term sheet ¹⁶.

Aaron Epstein, a founder in the ecosystem, publicly endorsed the firm: “This is the series A investor I always wanted — Fill out a quick form, like applying to YC — Fast decision — No board seat — 10% dilution — Group office hours instead of board meetings […] @standard_cap should be your first stop for series A” ²¹.

No additional independently sourced founder testimonials from portfolio company founders were found. The firm launched in late 2025 and has a limited public track record of founder feedback at this time.
