Test it before you build it
$1,400 · 4 weeks · 35 prospects
For $1,400 and 4 weeks of calls, prove data center developers will pay a $5,000 retainer and stalled solar developers will sign listings to trade ERCOT queue positions through a broker they have never heard of.
Riskiest assumption · A data center developer that needs ERCOT megawatts before 2029 will sign an exclusive paid mandate with an unknown broker instead of continuing to source queue positions through the lawyers and consultants it already pays.
1Focus group: who and where
The VP of energy or site selection at a US data center developer or operator (colo or AI compute buildout with a 50-500 MW pipeline) whose own ERCOT interconnection requests sit behind 2030-plus study dates while a signed tenant needs power by 2028; on the sell side, the development lead at a solar developer whose ERCOT project holds a signed interconnection agreement but lost its offtake or financing.
where to find 35 · Pull sellers from the public ERCOT GIS Report interconnection queue and LBNL's Queued Up dataset (projects with signed IAs and no construction start in 18+ months); meet both sides at the Gulf Coast Power Association fall conference in Austin; reach buyers through 7x24 Exchange Lone Star Chapter meetings and warm intros from ERCOT-focused energy law firms and transmission consultants.
2Sell first, build later
An exclusive 90-day buy-side mandate: GridStake sources, values, and presents at least three ERCOT queue positions with signed IAs and 2027-2028 energization matching the buyer's megawatts and timeline, and runs the transfer paperwork through partner counsel, first positions presented within 30 days of signing.
the ask · $5,000 retainer per mandate plus a 2% success fee on the transfer price, retainer credited at closing; standalone valuation memos at $2,500 per position.
a real yes · A countersigned mandate with the $5,000 retainer paid, or a $2,500 memo invoice paid; 'send me deals when you have them', unpaid NDAs, and enthusiastic calls do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Buy-side mandate calls
$300 · 14 days
Build a two-page anonymized teaser of three real stalled ERCOT positions pulled from the GIS Report: signed IA, 2027-2028 energization, estimated network upgrade exposure per MW. Get warm intros through energy lawyers and GCPA contacts to 15 data center developers and pitch the $5,000 exclusive buy-side mandate on a 20-minute call. Founder runs every call personally.
keep going if · 8 of 15 take the call; 3 of 15 request the mandate agreement and the full position package under NDA
2. Paid valuation memo offer
$100 · 10 days
Offer the same buyers a $2,500 desk valuation of any queue position they are already chasing on their own: survival probability, upgrade exposure, and comparable asks, delivered in 10 business days. This tests whether the pricing model alone is worth money even when GridStake is not the broker.
keep going if · 2 of 10 offers convert to a paid $2,500 memo
3. Seller listing calls
$250 · 14 days
Pull 20 stalled ERCOT solar projects from the GIS Report and Queued Up, cold-call the development leads, and ask each to sign a 90-day exclusive listing with a named ask price for the queue position. Log the reason for every no.
keep going if · 5 of 20 sign a 90-day exclusive listing with a stated ask price
4. Counsel transfer-path check
$750 · 7 days
Pay for one hour each with two ERCOT-focused energy attorneys to confirm that a project-entity sale transfers the queue position without triggering re-study, and to vet the mandate and listing templates. This is the regulatory kill switch the risk analyst flagged, verified for $750 instead of assumed.
keep going if · 2 of 2 attorneys confirm a transfer path that closes in under 90 days without re-study
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$5,000
per prospect, refundable
how · A retainer invoiced at mandate signing and paid by ACH or wire, the instrument this buyer already uses for law-firm engagements; a checkout link would read as unserious at this deal size. The buyer's VP of energy signs the two-page mandate and GridStake countersigns. set up: Stripe Invoicing ↗
what it reserves · Exclusive 90-day sourcing against the buyer's stated megawatt and timing spec, first look at the three positions currently in diligence, and full credit of the retainer against the 2% success fee at closing.
refund · Refunded in full if fewer than three qualifying positions are presented within 90 days.
target · 3 paid $5,000 retainers from 15 buyer conversations within 30 days
before taking money · Queue positions change hands through project-entity sales governed by FERC and ERCOT rules, so have energy regulatory counsel approve the mandate and fee structure before any transaction closes, and never hold buyer or seller funds yourself.
Go: build it if
3 buy-side mandates signed with retainers paid, 5 seller listings signed, and both attorneys confirm a sub-90-day transfer path, all within 4 weeks.
Kill: stop if
After 15 buyer calls and 20 seller calls: zero retainers paid, fewer than 2 listings signed, or either attorney says ERCOT transfers trigger re-study that resets the buyer's timeline.

We broker transfers of live interconnection positions from stalled solar projects: signed interconnection agreements, 2027-2028 energization dates, priced by survival probability and upgrade exposure. Three positions between 100 and 400 MW are in diligence now. Worth a 20-minute call this week to walk through the teaser?

The idea in full
- What
- GridStake is a US marketplace where data center developers, renewable developers, and industrial buyers purchase interconnection queue positions and grid capacity rights from projects that will never build. An ML valuation engine trained on utility studies, FERC filings, and historical queue outcomes prices each position by survival probability and network upgrade exposure, and the company runs the regulated transfer paperwork through partner transmission consultants and energy law firms who bring both sides of the trade.
- Why now
- Lorica (Antler UK 2026) frames a $3.5 trillion energy transition investment gap, while YC W26 funded Condor Energy for enterprise energy procurement and Voxel Energy for energy independent data centers - grid access, not generation, is now the scarce asset buyers will pay for.
- Wedge: first customer and entry point
- Start with a single ISO region, hand-brokering queue position transfers between stalled solar projects and data center developers who need megawatts in under three years, with the valuation model as the pricing authority.
- Path to 100x
- Grid capacity becomes an asset class and GridStake is its pricing venue: a few percent take on transfers within a $10-100B market for interconnection rights, with liquidity network effects making the first venue with both sides the only venue. Its transaction history becomes the only credible price record, so every later entrant prices off GridStake's data.
- Ceiling
- Regulators cap how freely queue positions can change hands, limiting annual transaction volume regardless of demand.
- Closest real companies, as the generator saw them
- Condor Energy sells procurement software for buying power; GridStake transacts the grid access rights themselves. Voxel Energy sidesteps the grid with on-site solar and batteries; GridStake makes the grid itself tradable.
- Main risk
- FERC or state commissions tighten queue transfer rules and the underlying asset stops being transferable.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
5/5
A take rate on interconnection rights with liquidity network effects and the only price record makes GridStake the venue everyone else prices off.
Bootstrapper
3/5
Hand-brokered queue transfers can bill fees early, but FERC rules deciding whether the asset is transferable at all is a coin flip.
Operator
4/5
Data center developers already pay lawyers and consultants for queue positions, so the willingness to pay exists before the marketplace does.
Technologist
2/5
The ML pricing model rides public FERC filings while the real work is hand-brokering transfers through law firms, which is process, not defensible engineering.
Risk
2/5
The entire tradable asset exists only while FERC and state commissions permit queue transfers, a single rule change away from zero.
trends
2/5
Interconnection queue pain is real but rests on a data center demand story absent from the brief, and queue backlogs were already notorious in 2023.
