4 of 6 statistics carry a figure for this sponsor. A rate is published from 3 resolved vehicles and a median from 3 observations: two points have no middle, and a rate over two can only be 0, 50 or 100. Counts have no threshold — a count is an observation, not an estimate.
Everything marked derived is arithmetic we did to rows we hold, not a figure any filing states.

Score breakdown
every component, what it measured, and what it could not- Deal completion20% weightn=425/100
1/4 resolved vehicles closed a deal (25%); 2 liquidated, 1 terminated. No measured post-close outcome yet, so completion credit is NOT gated — missing data is never a penalty.
- Liquidation / termination drag16% weightn=419/100
2 liquidations and 1 termination across 4 vehicles raised → 81% attrition (terminations 1.25×, stale shells 0.75×).
- Post-close outcome quality40% weightnot measurable
Not measurable: 1 completed deSPAC, none with an honest post-close price (1 no stored price). A missing price means "bought out at a price no free feed carries" as often as "collapsed", so it is held neutral and never guessed.
Held at the neutral 50 across its full 40% weight — missing data is never scored as a failure, but it never earns credit either.
- Redemption behaviour10% weightnot measurable
1 redemption event(s) on file but none state a rate — not measurable, held neutral.
Held at the neutral 50 across its full 10% weight — missing data is never scored as a failure, but it never earns credit either.
- Extension reliance8% weightn=183/100
1 extension vote across 2 in-DB vehicles (0.5 per vehicle; 3+ scores zero).
- Live fleet vs trust6% weightnot measurable
No priced live vehicle — held neutral.
Held at the neutral 50 across its full 6% weight — missing data is never scored as a failure, but it never earns credit either.
- Measured weak recordflat penaltynot measurable
No measured prior-vehicle outcome — the weak-record rule cannot engage (absence of data is never a penalty).
How the number is built: weighted mean of the six components above = 43, then pulled 56% of the way back to the neutral 50 for small sample size (4 resolved vehicles) = 47.
3 components are not measurable for this sponsor (post-close outcome quality, redemption behaviour, live fleet vs trust) — 56% of the weight is a neutral placeholder rather than evidence. That is why the confidence chip reads medium.
How the Sponsor Score worksoutcome-first weighting
The score answers one question: did this sponsor make money for the people who held through the merger? Not “did they get a deal signed”. Those are different questions, and most sponsor rankings quietly answer the second one.
So post-close outcome quality carries 40% — the realised return of every prior vehicle we can price from a primary filing, measured against the $10.00 trust baseline. Deal completion carries 20%, and it is gated: closing deals that ended below trust value only earns part of the completion credit, because closing is a precondition for a return, not a return. Liquidation and termination drag takes 16%, redemption behaviour 10%, extension reliance 8%, and what the tape says about the live fleet just 6% — a quote is an opinion, not evidence.
A component with no data is never guessed. It is held at the neutral 50 across its full weight and labelled “not measurable”. Dropping it and re-weighting the rest would quietly reward a sponsor for having no verifiable record — exactly backwards. The consequence: a sponsor with no post-close evidence at all cannot read above 71, and cannot be labelled a strong operator no matter how many deals it closed.
Experience never inflates the score. There is no “years in business” component. A first-time sponsor sits at exactly 50 and reads “unproven” with low confidence — new is not bad. Sample size only pulls a score toward or away from that neutral 50, so nobody is called great or terrible on one vehicle.
Every input is a row already in the database, sourced from SEC primary filings: prior vehicles verified on EDGAR, redemption results read out of 8-Ks, prices from public feeds. The arithmetic is deterministic — no model, no LLM, no judgement call. Research tooling, not investment advice.

0 of 2 prior vehicles carry an honest post-close price, split-adjusted against the $10.00 trust baseline a holder gave up at the merger. Cash buyouts are read from the per-share consideration stated in the DEFM14A / SC 14D-9; a buyout no filing prices stays unpriced and stays out of the score. “Listing ended” means the quote stopped with no buyer — scored as a total loss because that is what the evidence says, but never printed as a percentage we cannot source.

Data provenance & audit trail1 internal entry
Written by SpacBrain’s data agents whenever a figure is captured, corrected or flagged, and kept verbatim so every number on this page can be traced back to the filing that states it. This is a running log, not the current record: an early entry may be superseded by a later correction — the panels above always hold the current values.
Grouped from primary Section-16 data. In-DB vehicles: FOUN, VCXB — linked because they share a Section-16 officer (or the same sponsor-LLC CIK), not because their names rhyme. Prior blank-check vehicles, each outcome re-derived from that vehicle's own EDGAR submissions: • EVe Mobility Acquisition Corp — TERMINATED; attributed through Ahmed Osman, a PRINCIPAL (CEO/chair/president) of FOUN; 8-K 2024-02-22 Item 1.02 (termination of a material definitive agreement), then 25-NSE 2024-12-27 with the blank-check name retained and no Item 2.01/5.06 ever filed • Noble Rock Acquisition Corp — LIQUIDATED; attributed through Singh Manpreet, an officer — not a principal — of FOUN, so this is the team member's record rather than proof the sponsor firm ran the vehicle; 25-NSE 2024-04-25 with the blank-check name "NORTHERN REVIVAL ACQUISITION Corp" retained and no 8-K Item 2.01/5.06 anywhere in its history Candidates whose EDGAR history was ambiguous were left out rather than guessed.
The Sponsor Score is a deterministic research heuristic over primary-sourced rows — never a recommendation, and never a prediction. It cannot tell you whether this sponsor’s next deal will work; it tells you, precisely and with its own uncertainty attached, what the last ones did.
