Detect the stack. Synthesize the pitch.
Mama runs the same tech detection as BuiltWith and Wappalyzer — across 25,000+ tools, refreshed every 4 hours. The difference: she tells you what each stack means for your pitch. Adds, drops, ICP-fit signals — synthesized into the brief, not dumped as a list.
The categories your buyer cares about.
We detect 25,000+ tools across 23 categories — but the brief surfaces the ones that change your conversation. Six categories drive 80% of the pitch-relevant signals across our data.
The change is the signal. Not the snapshot.
BuiltWith and Wappalyzer take snapshots — useful, but every list looks the same after 90 days. Mama tracks the deltas. When a tool gets added, when one gets dropped, when a stack rewrite is underway — that's the moment your pitch matters most.
Three independent signals, or it doesn't ship.
A single source missing one scan is the most common cause of false-positive tech detection. Mama only flags a change after at least two of three independent methods confirm it — so the brief never embarrasses your rep.

Confirms internal adoption, not just a marketing-team experiment."@amplitude/analytics". Confirms production-level integration.The stack is the input. The pitch is the output.
Tech changes are raw data. Mama synthesizes them into a sentence your rep can actually paste — by cross-referencing with the company's stage, your ICP, and what tools cluster around each change.
Rippling is mid-migration from Greenhouse to Ashby — confirmed by 14 new "Ashby" references in postings over the last 4 weeks. ATS swaps cluster with VP of People hires or TA leadership shifts — both worth checking before reaching out.
Linear is building a modern data stack from scratch in Q2 — Snowflake + dbt + Fivetran all added over 6 weeks, immediately following their first Senior Data Engineer hire. The "we just hired a data engineer" moment.
Notion just removed Pendo with no replacement detected. Either evaluating alternatives now or rolling their own product-analytics layer. High-intent window — the decision is open right now.
vs BuiltWith. vs Wappalyzer. Three different jobs.
BuiltWith has the deepest tech database. Wappalyzer has the slickest free plugin. Neither was built for outbound. Here's the honest comparison, written by us — read it with that in mind.
