# Build your own signal pipeline, or pull it from an API.

 Collecting funding, acquisition, and executive-move signals yourself is very doable. The hard part is keeping it clean, deduplicated, and fresh forever. Here's an honest look at the trade-off.

In short

 Building your own growth-signal pipeline is realistic, but the cost is rarely the first version, it's the ongoing maintenance: sources change, the same event shows up across dozens of outlets, and entity resolution is hard to get right. Datahyena does that unglamorous work so you get a clean, typed, deduplicated signal on day one. Build it yourself if signal collection is core IP or you have proprietary sources; buy if you'd rather spend that engineering time on your own product.

## Side by side.

Datahyena

 Building it yourself

 Time to first clean signal
 Minutes, after one API call
 Weeks to months of build time

 Deduplication across outlets
 Built in, one canonical event
 You design and maintain it

 Entity resolution
 Companies, investors, people resolved
 Hard to get right, ongoing

 Source maintenance
 Handled for you
 Breaks as sources change

 Freshness
 Updated continuously
 Depends on your cron and uptime

 Cost shape
 Usage-based, per record
 Engineering time + infra, fixed

 Source corroboration
 Cross-checked across outlets
 You build the heuristics

## Which one fits you.

### Choose Datahyena when

- You want a clean, deduplicated signal on day one, not in three months

- You'd rather point your engineers at your own product than at a scraping treadmill

- You need entity resolution and dedup handled, not reinvented

- Your volume is bursty or growing and you want usage-based cost, not fixed infra

### When building it yourself makes sense

- Signal collection is itself your core IP and differentiator

- You have proprietary or private sources an API can't replicate

- You have a dedicated data team that owns this long-term

- You need total control over every step of the pipeline

## What makes Datahyena different.

### The treadmill is the real cost

 A v1 scraper is a weekend. Keeping it accurate as outlets change formats, re-report the same round, and use a dozen names for the same company is the part that never ends.

### Dedup and resolution are the hard 80%

 Collapsing the same funding round from many outlets into one event, and resolving every company and investor to a canonical entity, is most of the work and most of the value. It comes built in.

### Spend the time on your product

 Every hour on a data pipeline is an hour not spent on what your users actually pay you for. Buying the signal layer keeps your team on your roadmap.

## Common questions

 Datahyena and Building it yourself, answered.

 Isn't it cheaper to just build it? The first version, maybe. The total cost is maintenance: sources change constantly, and deduplication and entity resolution take real, ongoing engineering. Usage-based pricing is often cheaper than a dedicated data hire once you account for that.
 Can I start with the API and build later? Yes. Many teams use the API to ship now and validate the use case, then decide whether owning the pipeline is worth it once the value is proven.
 What if I have my own sources? If signal collection is your core IP or you have proprietary sources, building can make sense. Datahyena is the better fit when you want clean public-event signals without owning the pipeline.
 How fresh is the API compared to my own scraper? New events typically appear within hours of being announced, updated continuously, which usually beats a self-managed cron once you account for source breakage and downtime.
