One data engine for
every client

Build a playbook once, run it for every client
Agencies don't need another point tool. They need infrastructure that makes the tenth client as easy as the first.
Standardize TAM building, decision-maker discovery, and enrichment into workflows you deploy per client, not rebuild per client.
Run the same playbook on client two, five, and twenty without multiplying your data bill.

The multi-client playbook

  1. Codify the playbook

    Turn your best-performing motion (TAM, decision makers, emails, signals) into a workflow built on clean endpoints.

  2. Clone it per client

    Duplicate the workflow, swap the ICP filters, and launch a new client market in hours, not weeks.

  3. Run it continuously

    Keep every client's market fresh with recurring searches, enrichment refreshes, and signal checks.

  4. Deliver and report

    Send validated data into each client's stack and show the pipeline your service creates.

Built for managed services

Use BlitzAPI to power the services you deliver: list building, enrichment, and outbound operations managed on behalf of your clients. Reselling or redistributing raw data as a standalone product requires a commercial agreement, so talk to us about a partner setup.

Managed services usage

Running BlitzAPI inside client engagements you operate is a standard, supported use.

Partner agreements

Reselling or embedding data in your own product requires commercial terms.

Discuss partner terms

AGENCIES

Every client engagement runs on the same infrastructure, scoped to its own workflows.

Frequently asked questions

Can we use BlitzAPI for client work?

Yes, under your own agency subscription and for your clients' internal B2B use. Powering managed services you operate (list building, enrichment, and outbound run on behalf of clients) is a standard use case. Redistributing or reselling the data is not part of it, and making it available to anyone beyond that engagement is not either. Our Terms set out the exact scope.

Can we resell BlitzAPI data?

Not without an agreement. Redistributing raw data or reselling it as a standalone product requires commercial terms. Contact us to discuss a partner setup.

How do we keep client workflows separate?

Run each client as its own workflow, with its own ICP filters, market definitions, and enrichment steps, so every engagement stays scoped to the service you operate. For dedicated setups and higher volumes, contact us.

Does BlitzAPI work with Clay and n8n?

Yes. BlitzAPI is standard REST, so it plugs into Clay's HTTP API for enrichment waterfalls and n8n's HTTP Request node for orchestrated workflows. Those are destinations for the workflows you run yourself. Listing, offering, or distributing BlitzAPI data or API access on a marketplace is a different thing, and our Terms do not allow it.
