Short answer
Building regulatory monitoring in-house is feasible for a narrow watch. The demanding part is the ongoing work: maintaining source coverage as sites and formats change, keeping relevance logic current, preserving evidence, and avoiding dependence on one person who holds the whole process in their head. Buying makes sense when that maintenance burden, and the risk of a single point of failure, outweighs the control of a bespoke build.
What You Are Really Building
A first version of an in-house watch is often a list of sources and a spreadsheet. The real system is everything that keeps it working: source pages that move or change format, new markets and topics, relevance rules that need tuning, evidence that has to stay attached, and a workflow the team will actually use.
Each of those is maintenance, not a one-off. The question is whether regulatory monitoring is something your organisation wants to operate as software, or something it wants to use.
The Bus Factor
Many in-house watches quietly depend on one experienced person. When they are on leave or leave the organisation, coverage and context can disappear with them.
A bought system should make the watch a shared system of record: sources, relevance, evidence, and decisions visible to the team rather than held in one head. That continuity is often the strongest argument for buying.
Frequently asked questions
When does building in-house make sense?
When the watch is narrow and stable, the team has engineering capacity to maintain it, and the cost of a missed signal is low enough to accept the maintenance and continuity risk.
What is the biggest risk of building?
Underestimating maintenance. Source coverage, relevance, and evidence need continuous upkeep, and an in-house tool often depends on a single person who understands it.
