3 teams that moved to python
3 teams moved to python. Most left Dinmo (1) or Clay (1). The typical team cut 94% of its bill. Each team's old bill, running cost and net saving.
Python scripts replaced data and sales-prospecting tools here, not hosting. Two of the three stories are one team. RovaAI replaced both Clay, $134 a month, and Apollo, $99 a month, in its outbound workflow with its own Python scripts. The scripts handle company lookups, contact enrichment and personalised first lines. Neither story gives a running cost, so both bills count as saved.
The third is much bigger and comes from an agency. MarginOps says a UK retailer dropped the Dinmo customer data platform, and the agency rebuilt segmentation, churn scoring and channel syncs on the Snowflake warehouse the client already ran. The figures, converted from pounds, are about $4,900 a month before and about $300 after in Snowflake costs, a 94% cut.
That retailer accounts for about 95% of the page's roughly $4,800 a month in savings. Because it is an agency case study with an unnamed client, the total depends on that one source. All three moves date from 2026. In each, a paid data tool was replaced by code the team or its agency now maintains.
