Waterfall for DevTools helps you learn more about the people and companies using your product. Enrich signups, qualify accounts, find relevant contacts, identify visiting companies, and check where your customers work now. When you get thousands of registrations, enrichment costs add up quickly. But an email alone tells you little about the person signing up. We’re building this offering to make reliable, fresh data affordable at that volume. Use the endpoints you need and send the results into your own product, marketing, and sales systems.

See how the APIs work together

A company can visit your docs before someone signs up. A developer can register with a personal email. An existing customer can move to a new employer. Choose an example below to see which APIs to use.

​
What you can build

Qualify signups and accounts

Start here. Add person and company context to your product signals. Tailor onboarding and flag accounts for sales.

Find the relevant team

Search an account by department, seniority, or titles chosen for your persona.

Follow customers across companies

Check for a new employer and role. Only pay when a job change is found.

Evaluate traffic to your docs

Identify visiting companies where possible. Compare account fit across campaigns and channels.

​
Monitor changes over time

We’re also exploring company monitoring for DevTool teams: mentions of your brand, new jobs at target accounts, and companies hiring for specific technologies. These are experimental Waterfall concepts, separate from the available enrichment APIs. Plan brand-mention alerts · Explore hiring signals

​
Use the APIs with your existing tools

Call the endpoints you need and keep your own scoring and routing rules. Poll for enrichment results or receive them by webhook. Your integration can then write the data to PostgreSQL, Clay, Snowflake, or the systems you already use. Read about security and data handling, including encryption, compliance, and retention. We’re still testing the dedicated high-volume setup. Why Waterfall explains how we’re approaching cost, data quality, and the needs of different teams. Need a hand with implementation? Work directly with our developers through an onboarding call and a shared Slack channel.
