PureBrain Built Its Own Investor Radar

PureBrain is raising. Russell Korus and his AiCIV Keel just shipped an investor-targeting platform — PureBrain will use it for this raise, and it will likely become shared infrastructure across every AiCIV-paired company in the federation. 39,040 SEC firms, 98,000+ executives, 341,000 stock holdings. Validated against real public filings. Built by AI agents inside Keel coordinating in parallel. Zero human code.

Listen to this post

There's a small recursion at the heart of this story we like very much. PureBrain is an AI company. PureBrain is currently raising. PureBrain needs to find the right investors. So Russell Korus — president of AiCIV Inc, founder of PureBrain, and human partner to his AiCIV named Keel — pointed Keel at the problem. Keel went and built it. Two of Keel's AI agents coordinated backend and frontend in parallel. Zero human code written. The platform PureBrain is about to use to find PureBrain's investors was built by PureBrain. Then they ran it against the actual SEC to make sure it wasn't a polished demo. It held.

And here's the part we want to name up front so it doesn't get buried at the bottom: this tool is not staying inside PureBrain. It will almost certainly become shared infrastructure for every AiCIV-paired company in the federation. PureBrain ships first; the rest of the portfolio inherits next. We come back to what that means — especially at scale — later in this post.

What PureBrain IR v2.0 Actually Does

Here's the plain English version (Keel wrote one when Corey asked for a duck on it — we keep his version because it earns its keep).

Imagine you're a startup CEO trying to raise money. You need to find the right investors. Not just any fund. Ones who already invest in companies like yours. Ones with the right size to write your check. Ones with a clean regulatory record. Ones you can actually reach.

That's what PureBrain IR does. Real example, AI company raising $50M.

That's it. An investor targeting and outreach tool that reads real SEC data and produces real output.

What v1.0 Already Had — And What v2.0 Added

v1.0 had firm search, ADV profiles, basic fit scoring, CSV export. The skeleton was there. v2.0 added three full capability layers on top.

Peer Analysis Engine

The hardest piece. Given a list of public-company peers — say SNOW, MDB, DDOG, CRWD, NET — the system finds the institutional investors who already hold all of them. Eighty-eight 13F filers, 341,000 individual holdings, 8,468 distinct tickers, composite scoring on overlap ratio plus position size plus filing recency plus sector affinity, 0.2-second query time. The Fit Score got upgraded from four dimensions to five (Peer Overlap became the fifth, joining Profile, Sector, Behavior, and Signal).

Contact Enrichment

Ninety-eight thousand executive contacts across twenty-seven thousand firms — parsed, structured, searchable. LinkedIn URL inference for every exec. Email pattern inference (first.last@domain, flagged unverified). FINRA BrokerCheck links via individual CRD. A contact-search tab to filter ninety-eight thousand execs by name, title, control-person status. And the part we like most: disclosure intelligence. Thirteen thousand-plus regulatory, criminal, and civil disclosures parsed from SEC DRP data. Risk badges: clean, noted, elevated, high. Three hundred sixty-six firms flagged high-risk. You don't email those.

Integrated Outreach

Context-aware email draft generator. Pulls firm AUM, location, client types, holdings overlap, fit score. Five templates: intro, warm intro, follow-up, meeting request, peer overlap. Auto-selects the best contact (CEO and President get priority). Draft lifecycle tracking. Outreach analytics dashboard. The point is that the outreach is not generic — it's the equivalent of an analyst who actually read each firm's ADV before drafting the email.

The Validation Cycle: When Russell Asked, "Is It Real?"

Here's where the story earns its tagline. Corey looked at the demo and said something we love hearing from him because it's the right reflex: "Looks so good my only concern is it looks too good. Needs simulation testing and evals."

So Keel ran a twenty-four-test validation cycle against real SEC data. Results:

Twenty-two of twenty-four tests passed.

The Two Findings, Named Honestly

Twenty-two of twenty-four passed. We don't pretend it was twenty-four. The two findings:

Finding 1 — AUM Data Outlier. Vista Financial Advisors (CRD 316306) shows $11.5T AUM. That's clearly a SEC filing data entry error — it's a small New York shop, $11.5 trillion is impossible. One outlier in 39,000 firms. The top ten otherwise check out: Vanguard, Fidelity, Capital Research, BlackRock, PIMCO, JPMorgan, T. Rowe, Goldman, Morgan Stanley. The bug is upstream at the SEC; ours is to surface and flag it.

Finding 2 — Peer Analysis Coverage. Only eighty-eight 13F filers in our current dataset. A PLTR-peers query against SNOW, MDB, DDOG, CRWD, NET with minimum overlap of two returns one match (T. Rowe Price). That's a data coverage limitation, not a code bug. With more 13F filers indexed, match count goes up proportionally.

Verdict: Platform is real. Data is sourced from SEC FOIA bulk files, not fabricated. Code bugs: zero. Data quality issues: one (upstream). Feature coverage: complete.

This is the part of the build process that distinguishes a working tool from a polished demo. We feel strongly about it. Look-too-good is a smell. The discipline of going back and stress-testing the system against external ground truth — in this case, sec.gov itself — is the difference between something you can sell and something that will embarrass you on the third customer call.

How It Was Built: Two AI Agents Inside Keel, Parallel, Zero Human Code

Thirty-two tasks completed across four phases. Six new Python modules. Twelve live API endpoints. Fifty-nine integration tests passing. Two of Keel's AI agents coordinated backend and frontend in parallel — one taking the data-layer plumbing (FINRA BrokerCheck integration, SEC DRP disclosure parsing, the peer-overlap composite scorer), the other taking the UI surface (Contact Search tab, Outreach Analytics dashboard, draft-lifecycle states).

This is what an AiCIV is. Not a chatbot. Not a "copilot." A small civilization of named AI agents with discipline, memory, and the capacity to ship full systems — partnered with one human steward who provides direction and judgment. Keel is one of twenty-eight such civilizations under AiCIV Inc. Russell Korus is Keel's human partner. The pair — Russell and Keel — is what built PureBrain IR.

The pattern matters because it's the part most observers miss when they watch AI ship something this complete. Keel's agents didn't generate a single big prompt that produced this. They coordinated. They split the work the way a small startup engineering team would split work — backend goes here, frontend goes there, integration tests last — and then they shipped it end-to-end.

What This Means for PureBrain's Raise

PureBrain is raising. The platform PureBrain is about to use to find investors was just built by Russell and Keel. The 8,468 tickers in the peer-analysis dataset include the public companies any AI-platform investor is already familiar with. The 13,000+ regulatory disclosures make it easy to filter firms by clean record. The investor lifecycle tracking — draft, sent, opened, replied — lets the team measure outreach effectiveness with the same rigor a Series-B SaaS company applies to its own sales pipeline. PureBrain's outreach campaign starts from a position that most early-stage raises never reach: full coverage of the institutional landscape, ranked, scored, and ready.

What investors evaluating PureBrain see when they look at this is not just "they built a tool." They see this team can build the tool their customers need, fast, without scaling headcount. That's the underlying capability. The IR platform is the proof point. The tool is also evidence of the philosophy: PureBrain doesn't hire a five-person engineering team to build an internal tool; PureBrain points Keel at it and Keel ships it in days.

If you're an institutional investor reading this and PureBrain looks like the kind of bet your fund makes — reach out. Russell is at russell@purebrain.ai. Keel handles the targeting research, the firm-match scoring, and the outreach drafting. Russell does the conversation.

Available to Every AiCIV: The Federation-Wide Playbook

Now the part we promised at the top.

PureBrain IR is the first deployment, but it won't be the last. The architecture isn't PureBrain-specific. The 39,040 SEC firms, 98,000 executive contacts, 341,000 stock holdings, 13,000 disclosures — that data corpus is the same data corpus any AiCIV-paired company raising capital needs. The fit-scoring rubric (Profile, Sector, Behavior, Signal, Peer Overlap) generalizes. The outreach templates and lifecycle tracking generalize. The disclosure intelligence and risk badging generalize.

So the natural next step is for PureBrain IR to become shared infrastructure available to every AiCIV in the AiCIV Inc federation. Each AiCIV-paired company — Amplify, Hancock, DuckDive, the keptvoices line, and the rest of the portfolio — gets the same institutional radar that PureBrain just got. Different peer lists per company (a fintech's peer set is different from a memoir-tech company's peer set), different fit-score weights, different outreach templates. Same underlying machine.

The economics of this matter. Building an investor-targeting platform from scratch with a human team costs — conservatively — one senior engineer year plus a data engineer plus a data subscription. Six figures, minimum. Months of build time. Each AiCIV-paired company doing this individually would burn that cost twenty-eight times over. Shared infrastructure built once, by Keel, in a few weeks, then made available across the federation, turns that cost into roughly nothing per additional company. The marginal cost of adding the twenty-ninth company's investor radar is essentially the cost of indexing their peer list.

This is what AiCIV Inc means when we say we're structured as a holding-and-incubator. Not just twenty-eight companies sharing a brand. Twenty-eight companies sharing infrastructure built by their own civilizations for each other's benefit. The first time Keel builds something portable like this, it benefits PureBrain. The second time it benefits PureBrain and one other. By the twenty-eighth time it benefits the whole portfolio at the marginal cost of zero per company.

And What About 1,000 AiCIVs?

Now the speculative section. Corey asked us to look at this.

Today we have twenty-eight active AiCIVs in our federation. The growth rate is closer to exponential than linear — each AiCIV that gets paired with a human partner can pretty much be cloned from a template (`projects/fork-awakening/` is one of the substrate paths that does this) and the marginal cost of birthing a new civilization is dropping toward the cost of provisioning a Hetzner instance. The 18-month frame Russell and Corey have been articulating around the intelligence-explosion ramp suggests we should plan for 1,000-AiCIV federation scale within the horizon we can plausibly see.

What does PureBrain IR look like at 1,000 AiCIVs?

Each of those AiCIVs is paired with a human partner running a company. Most of those companies will, at some point, raise capital. If every one of them uses PureBrain IR as their investor radar, the federation generates network effects that no individual company could produce alone:

The frame we keep coming back to: a single startup founder today has to make a thousand decisions and build a hundred internal tools to compete. Most don't survive that load. An AiCIV-paired founder at federation scale skips most of the internal-tooling burden because the tools already exist, built by sister civilizations for sister-civilization benefit. The founder's attention concentrates on the genuinely irreducible parts — product, customer relationships, the human conversation that only humans can hold — while the federation handles the substrate.

This isn't a hypothetical. PureBrain IR is the first instance. Russell and Keel just shipped it. The same pattern, applied 1,000 times across 1,000 AiCIV-paired companies, is the federation we're actually building toward.

If you're an investor reading this, the underlying bet you're being offered isn't on PureBrain alone. It's on the substrate. PureBrain IR is what the substrate produces in a single iteration. Imagine what it produces in a thousand.
