We’ve been working with the team at Summ for the past three months. Time to make it official.
Summ (formerly Crypto Tax Calculator) helps crypto investors across 180+ countries get their tax reporting right, backed by Airtree and Folklore Ventures, with integrations across 3,500+ platforms. Thousands of token types, hundreds of exchanges, different tax rules in every jurisdiction. Most fintech companies won’t go near it. Summ built the product that handles it.
When they brought us in, the priority was clear. Get attribution locked down, tighten acquisition costs, and build the infrastructure to scale paid media across new channels and markets ahead of peak tax seasons.
In 90 days, working together, we rebuilt attribution from the ground up, cut acquisition costs by over 50%, launched new paid channels, and scaled the US campaigns during peak season.
This is a team that operates async across four continents and still moves faster than most companies in one office. They think in full-funnel terms, they’re sharp on measurement, and when we bring them a big swing they back it without three rounds of approvals.
Now we’re into the next phase. Demand gen for AU tax season, new channel expansion, and scaling what’s already working across geos. A lot still ahead with Michael, Jack, Sarah and the wider Summ team.
