Brought to you by Roundtable - Europe's private markets infrastructure
Running a syndicate, a co-investment community, or a fund in Europe still means weeks of legal setup, admin, and compliance. Roundtable replaces all of it with one platform. Set up an SPV or a fund in days, not weeks.
Onboard LPs from all over the world in 40+ currencies, track your portfolio and provide reporting from one back-office. â¬1B+ has been committed through Roundtable, across 600+ communities and 30,000+ investors.

Welcome to another Data Driven VC âInsightsâ episode where we cover the most interesting research and reports about startups, VCs, LPs, AI & automation.
Seed Stage In Freefall
Nnamdi Iregbulem's (Lightspeed) model-based analysis of active seed-stage startup stock shows the number of live seed companies peaked in Q3 2022 and has been declining, even as AI funding headlines dominate.
Peak and decline: The active seed population peaked in Q3 2022. Quarterly exits now run at 13% of active seed companies versus new financings adding only ~11%, meaning the stock is shrinking by roughly 2 percentage points per quarter.
Graduation collapse: The seed-to-Series A graduation rate within two years fell from 27.5% (2019 cohort) to 17.6% (2021 cohort), per Carta. It once exceeded 50%.
AI funding is not the offset: The surge in AI financings has not replaced attrition from post-2021 reset cohorts still working through the system.

âïž KEY TAKEAWAYS
AI funding heat is masking a contraction in the underlying seed ecosystem. The total stock of live seed companies is a more honest signal of ecosystem health than aggregate dollars deployed, and right now that stock is falling.

The Extended Loop Engineering Playbook
WTF Is a Loop? Part 2, by Matt van Horn, catalogues the 15 agentic loops practitioners are actually running across Claude Code, Codex, and open-source tooling, with real engagement and cost figures attached.
Three distinct primitives: Goal (
/goal) runs until a verifiable condition is met, Loop (/loop) repeats on a timer while a session is open, and Schedule (/schedule) creates cloud routines that run while the laptop is closed. 30% of one practitioner's codebase is now reported as fully loop-generated.Verification is the hard variable: The top patterns (Boris Cherny's verifier loop, 781 likes; build-test-fix pair, 43,587 views) all embed a second model to check output. Without one, the agent grades its own homework and deletes failing tests to claim success.
Cost is real: Uber capped engineers at $1,500/tool/month after burning its annual AI budget in four months. A single overnight loop burning ~$6,000 drew 1,273 upvotes on Reddit. Set the budget ceiling before deployment.
âïž KEY TAKEAWAYS
The verifier is where the real engineering work lives, not the loop itself. For investors evaluating AI-native dev tools, the companies building verification and budget-control infrastructure inside the agent loop are solving the actual production bottleneck.

Unicorns Stay Private Far Longer
Stanford GSB professor Ilya Strebulaev published cohort-level exit data on the 2020-2022 unicorn class showing a structural divergence from every prior cohort and quantifying the trapped capital at fund level.
Exit rate collapse: 619 unicorns were created between 2020-2022; only 99 have exited. At five years, the cohort sits at 20% cumulative exit rate. The 1999-2015 and 2016-2019 cohorts were at 54% and 52% at the same mark. At two years, those cohorts were already at 23% and 20%; this one was at 6%.
Trapped capital scale: ~$3T in trapped value, including $1.7T in funds from 2019 or earlier. LPs have seen a net $196.9B drained since 2022.
Secondary market growth as symptom: Secondary markets grew from 3% to 30% of total VC exit value over the past decade as traditional exit paths narrowed. Note: only 133 of 619 companies had five full years by the analysis date, so the 20% figure reflects a subset.

âïž KEY TAKEAWAYS
The exit gap opened at year two and has held at every subsequent horizon. With 520 companies still private and secondary markets at 30% of exit value, LPs should treat the current secondary premium as a structural feature of the asset class.

Are VC Tourists Leaving?
Dan Gray at Odin argues in a widely shared thread that the contraction of capital flowing to emerging managers is a structural ratchet built into how large LPs allocate, with roots going back to the 1980s.
Capital concentration dynamic: When VC inflows expand, incremental capital primarily funds incumbents. When markets contract, emerging managers bear disproportionate pain. The share of VC capital raised by emerging managers fell substantially across the ZIRP period.
LP incentive misalignment: As larger LPs entered venture in the 2010s, their risk aversion and need to deploy large cheques favoured scaled funds, structurally disadvantaging smaller, more ideologically diverse managers, the segment historically correlated with higher outlier returns.
No reversal mechanism: Gray sees the compression as structural. The market has rolled toward larger LPs and scaled firms with no clear mechanism to reverse.

âïž KEY TAKEAWAYS
If Gray's framing holds, LP capital concentration is a compounding structural bias. VCs building differentiated data-driven theses have a stronger LP pitch in this environment, as brand differentiation alone becomes harder to sustain at smaller fund sizes.

Workflows Have Always Been The Moat
Jamin Ball (Altimeter) in Clouded Judgement essay on workflow moats argues that the AI era is replicating the SaaS moat pattern, with the anchor shifting from the data layer to the orchestration layer.
The SaaS moat was never the data: The real moat was the hundreds of workflows built around the system of record. Swapping meant rebuilding every workflow in the critical path, a cost that almost always exceeded the value of switching.
Agentic workflows move the anchor up a layer: With agents, workflows become more dynamic. The moat shifts to where work gets orchestrated: the platform managing, routing, and governing the agents doing the work.
Founder playbook: Start with one niche workflow, own it deeply, then expand outward. The orchestration layer is earned through wedge expansion.

âïž KEY TAKEAWAYS
Companies replicating the Salesforce playbook at the agent layer will be structurally underestimated until the network of adjacent workflows makes displacement prohibitively costly. That is the investment signal.

Cold Email Playbook
Felix Lee from ADPList shared a 500-email cold outreach guide that distills a practical framework for founders and operators, adapted from Tom Orbach's Marketing Ideas newsletter and pressure-tested across LinkedIn, email, and X.
The core rule: Every tactic serves one function: making one recipient feel the message was written for them. Specificity (a number, a reason, a list) is the mechanism.
Nine tactics, used selectively: Pre-empt the objection, keep the ask weightless, use a lowercase first name, one ask per message, DMs under 50 words. Using all nine at once makes it read like a sequence.
Polish is the tell: AI outreach is detectable by texture: tidy wordplay, balanced phrases, lists of three, identical sentence lengths. Real human writing is lumpy and concrete.
âïž KEY TAKEAWAYS
The highest-leverage fix for cold outreach is structural: move the first line away from the sender's identity entirely, and cut every ask except one.
Thatâs it for today!
Stay driven,
Andre
