startup idea

Kilowire

An API that sells data center operators dispatchable headroom, metered by the megawatt hour.

Kilowire installs battery and controller hardware behind the meter at data centers and exposes one endpoint: how many megawatts a site can draw in the next fifteen minutes, and a call to reserve them.

Test it before you build it

$1,500 · 5 weeks · 15 prospects

For $1,500 and five weeks, prove that capacity-constrained colocation operators will pay $4,500 up front for battery-backed headroom on Kilowire's schedule instead of waiting out the utility queue.

Riskiest assumption · A colocation operator stuck in the interconnect queue will pay money now for battery-backed headroom that energizes on Kilowire's schedule, rather than waiting out the utility or buying and operating batteries themselves.

1Focus group: who and where

The COO or VP of operations at a colocation operator running 2-30 MW across one to five sites, with tenants asking for megawatts the site cannot deliver and a utility upgrade request that is years from landing - Northern Virginia on Dominion, Phoenix on APS, or Santa Clara on Silicon Valley Power.

where to find 15 · 7x24 Exchange chapter meetings in the Washington DC and Arizona chapters, the Data Center Map directory filtered to colocation sites under 30 MW in those constrained metros, the iMasons (Infrastructure Masons) member community, and warm introductions from tenants and data center brokers working those markets.

2Sell first, build later

A $4,500 design-partner feasibility study delivered in 30 days: the site's interconnect position and tariff, battery sizing for 2-8 MW of dispatchable headroom, a guaranteed deliverable MW figure and a binding price sheet the operator can take to tenants, plus first position in Kilowire's deployment queue for their metro.

the ask · $4,500 per study, credited against the first year's reservation charge of roughly $10-15 per kW-month if the pilot signs.

a real yes · A real yes is the $4,500 invoice paid up front and, later, a signed LOI with a dated construction start; enthusiastic calls, unpaid site walkthroughs and 'come back when the utility answers' are not yes.

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

  1. 1. Fifteen headroom offer calls

    $800 · 21 days

    Build a list of 40 sub-30 MW colos in Northern Virginia and Phoenix from Data Center Map, then land 15 calls through the two 7x24 chapters, iMasons and warm intros. On each call present a one-page offer: 2-8 MW of dispatchable battery headroom behind their meter, financed and owned by Kilowire, priced per kW-month reserved plus per MWh dispatched, with a $4,500 paid feasibility study as the first step.

    keep going if · 8 of 15 calls end with the operator asking for the study scope in writing

  2. 2. Paid feasibility close

    $400 · 14 days

    Send each interested operator the two-page study scope - interconnect position, tariff analysis, battery sizing, a guaranteed deliverable MW figure and a binding price sheet, delivered in 30 days - with an invoice for $4,500 payable up front. Count signed scopes with money received.

    keep going if · 2 of 15 operators pay the $4,500 invoice up front

  3. 3. Term sheet stress test

    $300 · 14 days

    Put the pilot term sheet in front of each payer: 2 MW minimum, a per kW-month reservation charge starting at energization, a dated construction start inside 12 months, and Kilowire's ownership of the asset. Count who signs an LOI with the date intact versus who says wait for the utility first.

    keep going if · 2 of 2 paying operators sign an LOI with a construction start date inside 12 months

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.

$4,500

per prospect, refundable

how · A paid design-partner feasibility study invoiced 100 percent up front, chosen because a mid-market colo COO can approve a $4,500 professional-services invoice without a procurement cycle, while a cash reservation on unbuilt batteries would stall in legal; the COO signs the two-page scope and accounts payable wires the fee. set up: Stripe Invoicing ↗

what it reserves · First position in the deployment queue for their metro, a locked reservation price on their first 2 MW, and the full study fee credited against year one of the pilot.

refund · Refunded in full if Kilowire does not deliver the study with a guaranteed MW figure within 30 days of payment.

target · 2 paid studies from 15 operator calls within 35 days

before taking money · Behind-the-meter batteries and grid services sit under utility interconnection rules and state and FERC oversight, so sell only studies and LOIs and make no dispatch, export or demand-response commitment before interconnection agreements and counsel sign off.

Go: build it if

2 or more paid $4,500 studies and at least 1 signed LOI with a construction start inside 12 months: the buyer commits ahead of the grid, so raise the asset capital.

Kill: stop if

0 paid studies after 15 calls, or every interested operator conditions payment on the utility approving upgrades first: stop, the five-year clock kills the buyer's willingness to commit and this is project finance without a customer.

outreach message

You have tenants asking for megawatts you cannot deliver, and the utility's answer is measured in years. I put batteries behind the meter at colos like yours - I finance and own them - and sell you 2 to 8 MW of dispatchable headroom, metered per kW-month, that you resell to tenants at your margin. The first step is a $4,500 feasibility study with a guaranteed MW figure, delivered in 30 days. Can I take 20 minutes this week to talk through your site?

The idea in full

What
Kilowire installs battery and controller hardware behind the meter at data centers and exposes one endpoint: how many megawatts a site can draw in the next fifteen minutes, and a call to reserve them. Compute schedulers and colocation operators sign up self-serve, meter usage per megawatt hour, and Kilowire holds the interconnection agreements, grid-code certifications and demand-response contracts underneath. The capital sits in the storage assets Kilowire owns at each site; the product enterprises touch is only the API.
Why now
The cluster's newest cohort is all about power for compute: NODI Energy (yc X25) on unlocking grid power to data centers, Voxel Energy (yc W26) on energy independent data centers, voltiumAi and DataTherm (techstars TS 2025) on data center energy and waste heat. The 2024 cohort peak of 91 new companies falling to 29 in 2025 and 10 in 2026 says the field-deployment layer is thinning out just as the demand side keeps growing.
Wedge: first customer and entry point
One mid-size colocation operator sitting on an interconnect queue: give them 8MW of contracted headroom from batteries Kilowire owns, then expose that headroom to their tenants as an API.
Path to 100x
Data center power procurement is a $10-100B annual market and Kilowire takes a metered cut of it rather than a project fee; once schedulers, orchestration stacks and colo billing systems call the same endpoint, being already wired into the deployment path is the distribution moat. Every new site added widens the pool a single API call can draw from, which makes the platform more useful to every existing caller.
Ceiling
Hyperscalers build the same behind-the-meter capability in-house, leaving only a few hundred mid-market sites and a project-finance business rather than a platform.
Closest real companies, as the generator saw them
NODI Energy and Voxel Energy sell infrastructure projects site by site; Kilowire sells metered capacity through a single API that any scheduler can call across sites. voltiumAi optimizes energy inside a data center without owning dispatchable assets.
Main risk
Interconnection and utility approvals move on a five-year clock while the capital stack needs deployment on a two-year clock.

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

    3/5

    Metered API over $10-100B data center power is attractive, but Kilowire owns the batteries and interconnection runs on a five-year clock.

  • Bootstrapper

    1/5

    Kilowire owns the batteries at every site and waits on five-year interconnection approvals; that is project finance, not bootstrapping.

  • Operator

    3/5

    Colocation operators desperately want contracted headroom, but Kilowire owns the batteries and interconnection runs on a five-year clock.

  • Technologist

    3/5

    Owning batteries and grid-code certifications is real, but the fifteen-minute headroom API is thin software over what is really project finance.

  • Risk

    3/5

    Kilowire holds its own interconnection agreements and grid-code certifications, yet five-year utility approvals against a two-year capital clock is a hard timing mismatch.

  • trends

    3/5

    Same genuine 2025-2026 data center power crunch as the cluster's W26 entrants, but capital-heavy batteries on a five-year interconnection clock blunt the timing advantage.
