Building useful things with great people

We're a small team of builders, engineers and operators.
We spend our days solving problems, shipping features and helping customers build better go-to-market systems.

Most of the best systems we've seen weren't bought.
They were built.

BlitzAPI exists to give teams the data, signals, and building blocks they need to create their own advantage.

Records in our data infrastructure

A record is any object the infrastructure operates on: companies, people, job postings and signals. One organisation can account for many.

Small team, clear principles
big ambition

  1. 01

    Small teams move faster

    • We value ownership over process.
    • Good ideas can come from anywhere.
    • We prefer shipping, learning, and improving over endless planning.
  2. 02

    Curiosity is part of the job

    • We love exploring new technologies and unconventional ideas.
    • Learning is encouraged, experimentation is expected.
    • Some of our best products started as side projects.
  3. 03

    Long-term thinking

    • We focus on building things that last.
    • Sustainable growth matters more than short-term wins.
    • We optimize for trust, product quality, and customer success.

Everything you need to know

What is BlitzAPI?

BlitzAPI helps you find the right companies, the right people, and the right signals faster. You can use it to build your TAM, enrich records, verify emails, and analyze job postings from one place.

How accurate is the data?

Verified means tested, not guessed. Addresses are proven against live mail infrastructure before delivery and re-tested at least every 30 days, and anything we cannot prove comes back Not Found instead of a maybe. Records are refreshed continuously from real-world signals.

Do you offer custom data solutions?

Yes. That is Build Your Infra: rate limits, fair use policy, SLA, DPA, reseller agreement, dedicated servers, zero data retention and custom features, set with you on a call. It starts at $999 a month, and you can book the call from the pricing page.

How does pricing work?

Every plan opens every endpoint and every data type; plans differ by speed, fair use policy and support. Start is $99 a month for 10 requests per second per endpoint under a fair use policy of 200,000 records a month, Scale is $499 a month for 25 requests per second and 5,000,000 records, and Build Your Infra starts at $999 a month, fully custom, on a call. A record is one item the API returns: one company, one person, one email, one phone number or one job posting. Every account starts with 1,000 free records, no card.

What are the rate limits?

Start runs at 10 requests per second per endpoint and Scale at 25, under fair use policies of 200,000 and 5,000,000 records a month. If your workload needs more, Build Your Infra sets the rate limits and the fair use policy with you, on a call.
