Before. After.
Hyperline's old pipeline already worked — Apollo for sourcing, FullEnrich for waterfall, a hand-rolled Attio integration on top. It just took half a day to run, and by then the sales intuition behind it had gone cold. Pronto's API replaces Apollo + FullEnrich. Quentin uses Claude Code as his tooling — describing the workflow in English and writing the Attio dedup himself — but the data layer is one API.

Pronto's API does the sourcing, persona finding, and waterfall enrichment. Quentin's tooling — Claude Code — orchestrates it and writes the Attio dedup. Two products built to work together.Where Hyperline got stuck.
- Hyperline sells the modern system of record for revenue — to CFOs, Heads of Finance, and RevOps. A sharp, technical buyer base.
- Reaching them means precision targeting: "companies using this payment processor," "companies on this billing stack," "companies that just raised a Series B."
- Quentin had built a working pipeline — Apollo for sourcing, FullEnrich for waterfall, a hand-rolled Attio integration to push it all into the CRM.
- It worked, but each list took half a day. By the time the contacts landed in front of a rep, the original intuition had cooled.
- Worse, sales wasn't doing the scoping. Reps got handed lists they hadn't shaped — and called them with the energy of someone working a queue, not someone testing their own bet.
Sales would have an idea — 'let's try companies using this payment form' — and by the time we had the list ready, it was the next day. The intuition was dead.
How Pronto unlocked it.
Quentin doesn't write code professionally. But he does write English. He sat down with Claude Code and described the workflow he wanted in plain language, step by step — and Claude Code wired it onto Pronto's API. The whole pipeline now runs in under an hour, replacing what used to take Apollo + FullEnrich + a custom integration half a day to deliver. And because sales now scope their own segments, they call with conviction.
- "Find companies matching this criteria." → Claude Code calls Pronto's API.
- "Inside each company, find Finance Managers and RevOps." → Pronto returns the personas.
- "Enrich them — emails and phones." → Pronto's waterfall (replacing FullEnrich).
- "Check Attio. Skip anyone we already have." → Custom dedup, built by Quentin in Claude Code.
- "Push the rest into Attio." → Done. Under an hour, end to end.
From half a day to build a call list to one hour.
Test a market on Tuesday. Be live by Wednesday.
Hyperline's UK expansion isn't a 6-month roadmap — it's a sales-led experiment, city by city. A rep wants to try Manchester this week? Quentin re-runs the Claude Code recipe scoped to Manchester and an enriched Attio list lands the same hour. If reps connect, the city moves to live. If they don't, the next intuition gets tested tomorrow. Same playbook in London, Birmingham, Leeds, Edinburgh, Bristol — with one Pronto contract behind all of it.
One workflow, six cities. Sales tries a market on a Tuesday morning; Quentin runs the same Claude Code recipe scoped to the new city — and an enriched Attio list lands the same hour. Tested → live → next, on a sales rep's timeline, not a quarter.
3 ways Hyperline uses Pronto.
- 01
One API replaces three moving parts
Pronto's API does sourcing, persona finding, and waterfall enrichment in one call — replacing Apollo + FullEnrich + the custom Attio glue Quentin used to maintain. Three contracts and a half-day of orchestration collapse into a single workflow.
- 02
Claude Code as the orchestration layer
Quentin describes each step in plain English; Claude Code wires it to Pronto's API and his own Attio dedup logic. No engineering tickets, no Zapier glue, no half-day integration projects. Same-day workflow changes when sales asks for a new filter or persona.
- 03
Sales-led segment testing
Reps bring intuitions — "companies using payment form X," "Series B with this billing stack" — and the list lands in Attio inside an hour. They call segments they helped scope, with energy and conviction. Pick-up rates go up. Bad bets get killed by tomorrow morning.
More customer stories
“15% of our new pipeline last quarter came from new hires. We wouldn't have spotted them without Pronto.”
— Baptiste, Sales Manager, UberCase studyWeYou Group“We replaced Evaboot with Pronto and plugged it straight into our CRM via API. Email enrichment doubled, we started cold calling for the first time, and every SDR went from 10 to 15 meetings a week. Across 35 SDRs, that's a different business.”
— Alexis Gadrat, Head of Sales, WeYou GroupCase studyYousign“We replaced Evaboot, BetterContact, and our custom glue with Pronto's API inside Clay. Email and phone enrichment went from 55% to 85%, our tooling cost halved, and every account now lands in Salesforce with 3 verified contacts — even when the buyer's title is something nobody else would think to search for. That's what unlocked the team.”
— Paul de Framond, Senior Growth Outbound, YousignCase studyQevlar AI“From cold lists to 50+ Enterprise meetings a month — without adding a single SDR.”
— Thomas Bartelt, Go-to-Market Engineer, Qevlar AICase studyScalefast“We catch a new hire on day 1 — Clay would surface them 3 to 6 months in. That gap is the whole game.”
— Alex Jaglale, Founder, ScalefastCase studyBonx“We didn't replace Clay — we filled the gap Clay couldn't. Pronto found the Italian manufacturers Clay didn't index, and gave us phone numbers that actually rang. That's how we booked +6 meetings per rep in a market we couldn't crack before.”
