Questions & Answers

As answered by people managing SparkLoop and ServiceGraph.

What makes your product unique?

ServiceGraph's answer:

Most "where to launch / who to email / who to hire" lists online are stale — 2-year-old listicles where half the links 404, ChatGPT answers that invent URLs, frozen Notion lists nobody updates. ServiceGraph is the live alternative: curated datasets of product directories, business directories, newsletters and agencies, each row carrying real metrics — traffic, domain rank, subscriber counts, ratings — refreshed continuously and exportable as CSV or JSON.

Why should a person choose your product over its competitors?

ServiceGraph's answer:

Three reasons. (1) Freshness — most directory aggregators publish once and rot; we maintain ours as a living dataset. (2) Real metrics on every row, not just a list of names — filter directories by DR and traffic for SEO, newsletters by subscriber count for outreach, agencies by ratings and location for hiring. (3) Zero-friction trial — browse, search and filter completely free; 2,000 credits on signup, no card, credits don't expire.

How would you describe the primary audience of your product?

ServiceGraph's answer:

Founders and growth operators at early-stage startups, typically 1–10 people, who just shipped a product or are about to. They keep hitting the same three questions: where do I launch this, who do I email to grow, who do I hire. Solo indie hackers, small SaaS teams, and the marketers and agencies who serve them.

What's the story behind your product?

ServiceGraph's answer:

We built it for ourselves. Every time we shipped, finding the right places to launch and the right people to reach ate a full day of googling stale listicles and asking ChatGPT for URLs that didn't exist. We started maintaining our own list — with real traffic and domain-rank attached to each row — and realized every other founder was hitting the same wall. So we turned the internal tool into a product. Operated by NostrCorp, Inc. (Delaware).

Which are the primary technologies used for building your product?

ServiceGraph's answer:

TypeScript on the application side (web app and product API). Python for the data and ML pipeline that enriches and classifies rows across all datasets — directories, newsletters, agencies. ClickHouse as the storage and analytics backbone — chosen for fast aggregations across millions of rows so search, sort and filter stay snappy even on the 110k+ agencies dataset. REST API over HTTP exposed at docs.servicegraph.co.
