I’m hiring a Chief of Staff to help build the next chapter of @AICouncilConf & @ZeroPrimeVC.
Most of your time will go toward running and growing AI Council. You’ll also work closely with me across both orgs to get important work done.
This is for an unusually capable generalist. The scope is intentionally broad and expected to grow. The right person will earn ownership quickly and can develop toward broader operating leadership over time.
Full time, in person in San Francisco (office near Jackson Square).
Base salary of $150,000–$180,000, based on experience.

If someone comes to mind, send this their way.

Build your own harness.
This is a seriously good paper from NVIDIA on self-improving agent harnesses.
The paper is called SoL-Pi, out of NVIDIA, NTU and MIT.
Every coding agent runs inside a harness. That's the layer that reads files, runs commands, manages memory and talks to the model. Humans tune it by hand, reading long execution logs and turning what they notice into code changes.
They handed the job to an AI instead.
A research AI watched a coding agent work, proposed changes to the harness, tested them, and kept only what saved tokens without hurting results. It ran about 150 research directions across roughly 500 environments, more than 3,000 runs and over 60,000 agent-environment interactions.
Four fixes survived.
1. The agent edits a file and runs the test in one call instead of two.
2. It compresses its memory when a subtask finishes, and only if that's cheaper than keeping everything.
3. It sends big tool outputs in full twice, then swaps them for a 1KB excerpt with a handle to pull the rest on demand.
4. A cheap model summarizes build and test logs, and a verifier rejects the summary if it drops evidence.
None of that touches the model. It's all in the software around it.
On EdgeBench, a 51-task benchmark, token traffic dropped 44.7 to 49% and API cost fell by about a third against Pi, the harness it was built on. Against the native harnesses it came in 50% cheaper than Codex on GPT-5.6 Sol and 54.3% cheaper than Claude Code on Opus 5. Scores held at roughly 94% of the baseline.
They built all of it on GPT-5.6 Sol, then dropped it onto Opus 5 with zero changes. It still used 44.7% fewer tokens.
The cost conversation so far has been about cheaper models. This paper says a big chunk of the waste sits in the software around the model, and an AI finds it faster than we do.
Their next move is running the search again with the cheaper harness, so a cheaper agent funds the search for an even cheaper one.

Excited to be amongst such great emerging managers! 🚀
Which emerging VCs have the strongest early-stage picking alpha?
Standard emerging manager evaluation still leans heavily on qualitative signals – GP background, thesis articulation, founder references. All useful, but by the time TVPI and DPI tell you something meaningful, you're usually already in or already too late.
So I experimented with a quantitative framework to answer a core LP allocator question: which small, early-stage fund managers consistently back seed-stage companies that go on to raise exceptional Series A rounds – before those outcomes are visible to the broader market?
I started with @harmonic_ai Scout (my fav research tool!) and checked every company globally that raised a first pre-seed or seed round between 2022–2026 (Post-ZIRP). The funnel looks like this:
1/ 55,491 companies raised a pre-seed or seed round – the full opportunity set
2/ 4,368 (7.9%) went on to raise a Series A – the base rate, roughly 1 in 13
3/ 764 (1.4%) qualified as Tier 1 Breakouts – above-median Series A for their vintage year, with at least one top-tier institutional VC (from a defined set of 38 firms: @a16z, @sequoia, @lightspeedvp, @IndexVentures, and peers)
For each of those 1,604 companies, I traced back to every investor who backed them at pre-seed or seed — before the outcome was visible. 4,176 unique investors across the breakout set.
Then I computed a simple ratio for each: breakout companies backed at seed divided by total seed investments in the period. I'm calling this the "Tier 1 Concentration Rate".
After filtering out mega-platforms, accelerators, CVCs, and angels and requiring a minimum of 10 seed deals – 20 emerging managers (sub-$250M AUM) surfaced with notably high concentration rates.
A few things stood out:
1/ Several micro-funds under $100M were placing 25–35% of their seed bets into companies that later raised from @Sequoia, @a16z, @lightspeedvp – consistently, not as one-off flukes.
2/ Participant concentration and lead concentration are different signals. Participant = network and access. Lead = independent conviction before consensus forms. For LP diligence, these deserve to be evaluated separately.
3/ The data has real limitations: ~12% of breakout companies had no named seed investor in the database, we can't cleanly separate Fund I from Fund III for a given manager, and small sample sizes mean some high concentration rates likely reflect luck rather than repeatable skill.
But the core idea holds. "Tier 1 Concentration Rate" is an early, measurable signal of picking ability – observable years before fund-level metrics tell you anything.
For LP allocators evaluating Fund I–III managers, that timing gap is the whole problem. This is one attempt to close it.
What’s your take on this experiment?

I’m excited to let you know that we’ve changed our name to AI Council.
You might be thinking we’re just another conference jumping on the AI bandwagon. But if you’ve been in our community for long enough, you know that we changed our name to Data Council five years ago to shift away from “Big Data” buzzwords toward a community for the engineers doing technical work.
A lot has happened since. The AI revolution our community had been building toward finally arrived – and Data Council continued to grow into something bigger.
The truth is, what we’re solving for hasn’t fundamentally changed. We’re still building the data-driven systems that power AI innovation. But data and AI are inseparable, and it’s time for our name to reflect what we’ve already become.
Welcome to AI Council. Same technical depth. Same no-bullshit culture. New name.
