I’m a former investor in the company. Many comments here focus on the DNA business, but the company treats it as more as lead gen, a “cheap” way to get new customers in and later to subscribe to their family tree product that prints cash. The DNA business is breakeven but that’s a lot cheaper than funding TV shows like Who Do You Think You Are - which was their old marketing tool.
Funny anecdotes: - they own findagrave.com which is exactly what it sounds like - they paid $50mm at one point to the Mormon church to effectively shut down their only competitor (family search.org). They also offered ancestry.com membership for free to every Mormon as well. The agreement handed over Mormon church’s records making Ancestry’s database broader. - they sometimes call themselves a “Social Network for dead people” because you can opt to make your family tree public, allowing you to see connections/overlaps between your ancestors and others.
