//Intelligence for down-ballot races

The intelligence
your opponent
doesn't have.

Culper is campaign software for local and down-ballot candidates — city council, school board, mayoral, and state-legislative races. Voter database, SMS and email outreach, volunteers, block-walking, and donations in one platform. No consultant. No spreadsheets.

01The problem

Local candidates
have been running
blind.

National campaigns hire analysts and buy six-figure data stacks. Local candidates cobble together Mailchimp, a Google Sheet, and a $40k consultant who runs queries for them. The tools aren't the same. The races aren't fair.

02The spine

Your voter file,
answerable in English.

Every outreach, every door, every dollar flows through the voter record. Import your file. Then ask it anything — like you'd ask a staffer.

  • CSV import from L2, i360, or any provider
  • Segment by age, party, precinct, vote history
  • Save lists, share them across outreach and walks

The safety architecture

The model emits a constrained JSON grammar. A validator compiles it to parameterized SQL against a campaign-scoped view. No raw SQL ever leaves the model's mouth.

03The ground game

Close the loop
on every door.

Assign walk routes from any saved list. Volunteers log every conversation from the phone — receptiveness, issues, yard signs. Results flow straight into the voter record. Your next mailer reaches the exact right doors.

04The platform

One system.
Six integrated surfaces.

Pull any one out and it still works. Together, the data compounds across features, across weeks, across election cycles.

01

Voter intelligence

Import your file. Query it in English or filters. Save lists that feed every other surface.

02

SMS + email outreach

Send to any saved list. Templates with variable interpolation. Delivery and open tracking.

03

Volunteer coordination

Invite links, role assignment, skill tags. Volunteers log into the mobile app for assignments.

04

Block-walking telemetry

Assign routes from voter lists. GPS-verified visits. Survey data flows back to the voter record.

05

Donations + embeds

Stripe Connect for the committee account. Embeddable donation widgets for the existing site.

06

Compliance built-in

A2P 10DLC registration wizard, TCPA-aware opt-out, global suppression, per-campaign data isolation.

05The boring parts, done right

Built for the realities of political messaging.

Political SMS isn't regular SMS. You need a brand registered with TCR. You need documented consent on every number. You need to honor STOP instantly and globally, across every campaign. You need voter data walled off per campaign. Get one of those wrong and your campaign ends in a class-action.

Culper handles the A2P 10DLC registration wizard, logs consent at the source, maintains a global suppression list across all campaigns, and enforces per-campaign isolation at the database level with Postgres RLS. The boring parts, done right — so you don't have to think about them.

07FAQ

Questions candidates ask before signing up.

  • Culper is a campaign management platform built specifically for local and down-ballot candidates — city council, school board, mayoral, county-office, and state-legislative races. It bundles a voter database, SMS and email outreach, volunteer coordination, GPS-tracked block walking, and donation tools in one workspace. The major federal-campaign vendors like NGP VAN are priced for six-figure budgets; Culper is priced for races under $500,000.

  • Yes. Culper is positioned as an NGP VAN alternative for local and down-ballot candidates who cannot justify enterprise pricing. It covers the same core needs — voter targeting, outreach, volunteer coordination, block walking — and adds features VAN sells separately, like an integrated mobile app for volunteers and embeddable donation widgets.

  • Culper offers three tiers for the 2026 cycle. Challenger is for first-time candidates running a single race; Campaign is for serious local races with a dedicated team and includes the LLM voter query and donation widgets; Committee is for multi-candidate committees, county parties, slates, and PACs running multiple campaigns from one workspace. Final pricing is set after a short onboarding interview so it can match the scope and budget of the race.

  • No. Culper supports two onboarding paths: candidates in covered geographies can use Culper-provided voter data, and candidates anywhere in the country can upload their own licensed voter file (from L2, i360, Aristotle, the state Secretary of State, or an NGP VAN export). The product is fully functional in both paths — outreach, volunteer coordination, block walking, and the natural-language query layer all run against the candidate's own data.

  • Culper lets a candidate type a question in plain English — for example, 'registered Republicans over 55 in precinct 42 who voted in the last three primaries' — and returns a saved voter list. The LLM emits a constrained JSON query DSL, never raw SQL, which is validated server-side and compiled to parameterized queries that run against a campaign-scoped read-only Postgres role. The candidate does not need an analyst on staff to do segmentation work.

  • Culper ships a React Native mobile app for volunteers (iOS and Android). Walkers receive assignments, navigate stops on a map, log visit outcomes with GPS verification, and capture survey responses at the door. Every response flows back into the voter database as a campaign-scoped annotation, so the next round of texts and mail is precisely targeted.

  • Yes. Culper guides every candidate through The Campaign Registry's A2P 10DLC political-campaign brand registration as part of onboarding. Every outbound SMS requires documented prior express written consent under TCPA. Every STOP is honored instantly and propagates to a global, campaign-agnostic suppression list that no individual campaign can override.

  • Every campaign is a separate workspace with its own voter silo. Per-campaign data isolation is enforced at the database layer via PostgreSQL row-level security, not at the application layer. A volunteer who works on two campaigns has two separate memberships in two separate workspaces and cannot see voter data across them.

  • Culper supports individual candidate campaigns, PACs, county and state political parties, and coalitions or slates running multiple candidates on a shared platform. Onboarding is geography-agnostic — a candidate in any U.S. state can sign up today, regardless of whether Culper has licensed voter data for their district yet.

  • Culper is named after the Culper Ring — the intelligence network George Washington ran during the American Revolution. The product positions itself as intelligence infrastructure for down-ballot races: the same kind of data and operational advantage that federal campaigns spend six figures to assemble, packaged for the local candidates that big vendors don't serve.
