NakedPnL vs FundSeeder: The Closest Comparable, Honestly Compared
FundSeeder is the most direct comparable to NakedPnL: verified track records via broker connection. Here's an honest, side-by-side, no-spin comparison.
- FundSeeder (founded 2015 by Jack Schwager, Emanuel Balarie, and James Bibbings) connects traders to brokers (notably Interactive Brokers), publishes verified vs unverified track records, and matches traders with allocators.
- NakedPnL is a publisher only — no allocator matchmaking, no capital introduction, no signal services. It outputs a SHA-256 chained, Bitcoin-anchored TWR record across crypto exchanges, IBKR, Kalshi, and Polymarket.
- FundSeeder is the closest spiritual comparable. The honest difference: FundSeeder is positioned as a discovery/matchmaking platform with broker integrations; NakedPnL is positioned as a public publisher with a cryptographic chain and a strict no-arrangement compliance posture.
Verdict at a glance
Of all comparators, FundSeeder is the most directly analogous. Both products take the position that public, verifiable track records are valuable and that broker-side data is the right anchor. They diverge in two key ways: (1) FundSeeder layers a matchmaking and capital-introduction product on top of the verification, while NakedPnL stops at publishing and explicitly does not arrange anything; (2) FundSeeder's verification rests on direct broker integration without a public cryptographic chain, while NakedPnL exposes a SHA-256 chain that any viewer can re-derive in their browser.
If the goal is to be discovered by allocators with the help of a curated platform, FundSeeder has a longer track record and an active capital-allocation program (FundSeeder, in partnership with RQSI, has reportedly allocated capital to selected traders). If the goal is a viewer-verifiable, append-only public record with no matchmaking layer, NakedPnL is the only product currently shaped that way.
What they do differently
FundSeeder's core flow: a trader registers, links a brokerage account (Interactive Brokers is the largest integration; non-linkable accounts can upload via template, marked unverified), and the platform pulls daily data, generates analytics (equity curve, drawdown, FundSeeder score), and exposes the trader to a network of allocators. The platform is broker-agnostic in design, with IB as the dominant connection in practice.
NakedPnL's core flow: a trader connects one of six supported venues with read-only credentials, daily NAV is captured, the TWR engine produces a row, the row is SHA-256 hashed (over canonicalized broker payload), the hash is chained to the previous day's hash, and a daily Merkle tree of all chain heads is anchored to Bitcoin via OpenTimestamps. Public viewers can re-hash and re-link in a browser using Web Crypto, with zero trust in NakedPnL's servers required.
Feature comparison
| Criterion | NakedPnL | FundSeeder |
|---|---|---|
| Category | Verified-performance publisher / registry | Verified-track-record platform with allocator matchmaking |
| Custody model | None — read-only connections only | None — read-only broker linkage |
| API access model | Read-only API keys; IBKR Flex; wallet signatures | Direct broker linkage (Interactive Brokers etc.) |
| Verification mechanism | SHA-256 chain + daily Bitcoin OpenTimestamps anchor | Direct broker connection; verified vs unverified labels |
| Independent re-verification | Yes — browser-side SHA-256 re-derivation | No — trust in FundSeeder's broker-side connection |
| Public registry / leaderboards | Public registry of opted-in verified traders | Trader profiles visible to allocators; some public surface |
| Supported asset classes | Crypto, equities (IBKR), prediction markets (Kalshi, Polymarket) | Whatever IBKR (and other linked brokers) supports — futures, equities, FX |
| Performance metric | Time-weighted return (TWR), Decimal.js precision | FundSeeder score, equity curve, underwater curve, annualized vol |
| Cost to traders | Free tier; paid tiers for advanced features | Free for traders historically |
| Cost to viewers / allocators | Free public read | Allocator-side access varies by relationship |
| Regulatory category | Publisher of verified data — explicitly not an adviser/broker/copy platform | Platform with capital-introduction activity; relevant SEC/CFTC reg |
| Open-source methodology | TWR + hash algorithm published with re-derivation snippets | Methodology described; full reproducible spec not published |
| Privacy model | GDPR-aligned PublicConsent; opt-in and withdrawable | Trader controls profile visibility on platform |
| Capital introduction / matchmaking | No — platform stops at publishing | Yes — core part of the value proposition |
| Append-only history | Yes — chain rejects retroactive deletion | Trader can typically delete or reset profile |
Use cases
- Trader looking for capital introduction and curated allocator exposure: FundSeeder is in that business; NakedPnL is not.
- Trader who wants a public, viewer-verifiable record they can link from a website, X profile, or LP intro deck: NakedPnL's chain is purpose-built for that.
- Multi-venue crypto + prediction market trader: NakedPnL spans these natively; FundSeeder's footprint is more equities/FX/futures via IBKR.
- Allocator running due diligence: read-only across both is fine, but only NakedPnL gives a re-derivable cryptographic chain.
- Trader who explicitly does not want their record entangled with a regulated capital-introduction firm's process: NakedPnL is publisher-only.
Pricing
FundSeeder has historically been free for traders, with the platform's economics driven by capital-introduction outcomes rather than per-seat pricing. NakedPnL's trader-side tiers (FREE / PRO / FUND_DESK plus the capped Founding Lifetime program) gate features such as alerts, custom domains, LP-link sharing with watermark, and outbound webhooks. Public read access is free on both platforms.
Why this comparison is hard
FundSeeder is the closest comparable, but the comparison still bridges two different product shapes. FundSeeder is a discovery and matchmaking platform — its purpose is for allocators to find traders. NakedPnL is a publishing platform — its purpose is for the public to verify a trader. Both sit on top of broker-linked verification, but the activity layered on top is the difference. FundSeeder's incentive is to surface candidates to allocators; NakedPnL's incentive is to make verification cheap and re-derivable for any viewer, allocator or otherwise. A trader can reasonably use both in parallel.
