What we’re building

White collar businesses depend on fragile, time consuming data entry to plan, record, and execute work. Client services firms (~$10B TAM) are especially dependent on this broken process: lawyers, accountants, and consultants need to faithfully track their time in order to get paid. Lawyers spend an hour per day tracking their time, and fail to account for
20% of their work
.

Ajax frees hardworking professionals to do their jobs by passively capturing, analyzing, and preparing the reports they owe their boss/client/whoever.

Working at Ajax How we work, in practice

Here’s a real sprint we had in November:

During a pilot with an important firm, the GTM team noticed that activation was low

We pulled some data from Posthog and Metabase and came up with a hypothesis: these users were the fastest billers we’ve ever seen, and Ajax’s entries weren’t ready for them in time

Siyou restructured our React FE to show a Domino’s pizza style "entry in progress" tracker, assuring nervous billers that their work was indeed captured

Alex issued a native app update for our Flutter app that captured data more quickly when users task switch

Roger optimized some gnarly python async code to bring our p99 entry latency from ~180s to ~120s

We won the pilot!
