Why agencies use us even when they could DIY.
Thirty percent of our GMV is agencies. A few had the engineering capacity to run their own fulfillment and chose not to. Here is why.
Three of our largest agency customers employ engineers who could in principle build their own fulfillment pipeline. All three chose not to. Two said it explicitly at intake: the math does not work.
Follower fulfillment at scale requires a real account pool, source filtering, retention monitoring, refill scheduling, warranty economics, and compliance posture. Each of those is a multi-month engineering project. The all in cost to build it runs roughly $600K to $1.2M in the first year. For an agency doing $5M a year in social growth services, that is 12 to 24 percent of revenue burned on infrastructure that is not their core business.
The build versus buy math
Our Reseller tier margin of 15 to 25 percent per order is real money, but it is less than the cost of building equivalent infrastructure in house when amortized across volume. At $18,400 monthly GMV (the median for our Reseller tier customers), the margin differential against DIY is roughly break even after two years of operation. For agencies below that GMV, the math is decisively against DIY.
Above that GMV, the math starts favoring DIY, but three other factors keep agencies with us. First, the 24 month warranty is hard to match because the pool economics do not work on small DIY pools. Second, the API is more mature than most agencies want to build. Third, operational risk of being the middle agent between a fulfillment issue and a client is something most agency owners prefer to push upstream.
The practical conclusion
Build versus buy is not just about whether you could build it. It is about whether the build is worth the opportunity cost against serving clients. For most agencies in our category, the honest answer is no.
