Walter Chen (Sacra) on private market research, the AI coding race, and secondary market dynamics

Summary

Walter Chen is the founder and CEO of Sacra, a private market research firm that covers roughly 300 growth and pre-IPO companies in depth — a deliberate contrast to the three million companies tracked broadly by Pitchbook or Crunchbase. The business runs on two revenue lines: direct research subscriptions and an API product that embeds Sacra's analysis into secondary marketplace platforms. Customers include NASDAQ Private Market, EquityZen, Augment, and Caplight.

The secondary market angle is the core of Sacra's positioning. Buyers and sellers on these platforms often have little information on the private companies they're trading, and the marketplaces themselves need research content to engage participants. Sacra fills that gap. As part of some of those partnerships — including a collaboration with Augment on its Power 20 list — Sacra receives trading data in return, giving it a window into what is actually being bought and sold across platforms.

Data sourcing

Chen's most scalable data source is LinkedIn. Sales and marketing employees routinely post ARR milestones as personal accomplishments, which makes it possible to track revenue trajectories for companies that never publish financials. Beyond that, Sacra works directly with companies, taps SPV and syndicate networks where data circulates widely, and uses public regulatory filings where available — Column Bank, for example, files with the FDIC as a chartered institution.

AI coding market

Cursor's revenue growth from $100M to $200M to $300M ARR in quick succession is the benchmark Chen uses for the category. He acknowledges churn across AI coding products is relatively high, but argues the user acquisition velocity has overwhelmed it so far. His read post the OpenAI–Windsurf acquisition and the Codex launch is that the market is at or approaching peak fragmentation, with consolidation ahead as churn starts to compound. He frames the product landscape in layers: general-purpose models like o3 that write code incidentally to answer questions; Codex as a prosumer tool accessible inside ChatGPT; Windsurf and Cursor serving professional developers who need a full IDE; and enterprise-top-down plays like Cognition's Devin.

The addressable market math is straightforward: 1.6 million professional software developers in the U.S. as of 2023, median wage of $130,000 and fully loaded cost closer to $180,000, implying roughly $293 billion in annual developer compensation. A 20% productivity gain captured at 10% yields a meaningful wedge — and the calculus shifts further if companies that previously couldn't afford engineering teams start hiring single engineers to do the work of several.

Banking-as-a-service

Sacra covers Column Bank, founded by William Hockey and his wife Sarah, funded through proceeds from Hockey's Plaid secondary sale. Column is a vertically integrated API-first bank — they bought a chartered bank and retrofitted it with an API layer. Mercury is currently migrating off Evolve onto Column, which Chen sees as a quality signal given Column's higher compliance standards. Column and Brex are Sacra's two flagship BaaS coverage names. Chen notes he is personally a shareholder in both Brex and Ramp — a position he describes as held by a small handful of people globally — and believes both companies will scale despite the competitive narrative around them.
