About Guillaume Josset
We clean your CRM in 48h, AND keep it clean, so your dirty CRM never wastes your outreach again
If you run a sales team on HubSpot or Pipedrive, this one's for you: Every year, 30% of your contacts change jobs. And your database fills up with duplicates, dead contacts and wrong emails & numbers. Maybe your deliverability drops. Maybe your sales team calls people who left 6 months ago. Maybe your champion left and a competitor knew before you. However it happens, the result is the same: → You waste outreach. → Your sales team loses time calling dead contacts and manually updating the CRM. → You miss champions who move, and a competitor knows before you do. You've thought about fixing it. But buying more data just decays again in weeks. A one-time cleanup rots by next quarter. And doing it yourself burns a week of work. So your contacts keep moving, your data keeps rotting, and nobody sees it. That's why we built Dealmatching. We're the agency that cleans your CRM, then keeps it clean. OUR OFFER: We fix your whole CRM in 48 hours, done for you, then we make sure it never rots again. The system that keeps it clean was built with VPs of Sales from Deel, Meta, Snowflake, Klarna, Trustpilot, Revolut and more. Here is what we do: → We restore your base in 48 hours: outdated contacts, dead emails, duplicates, all fixed. → Then we set up the system that keeps it clean. → Every day it scans your contacts. → As soon as someone changes jobs, it updates the role, company, email and phone automatically, straight into your CRM. → Your rep is automatically alerted when a contact lands in an ICP account. You don't build a workflow. You don't manage anything. We set up everything for you. 40+ sales teams on HubSpot trust us today. And it's the fastest ROI you'll ever get: 48h after the audit, you already discover who moved. Want to stop wasting outreach because of your dirty CRM? Book a free CRM audit with us: 1. We connect to your CRM 2. You see how outdated your CRM is 3. You get a personalized quote to fix it with us All of this in 25 min.

It's official: today, we become an agency (and your messy HubSpot is exactly why) → here is the story: On LinkedIn, you know us for Dealmatching: → a tool that catches your contacts' job changes and fixes CRM decay. → from 0 to 40+ B2B sales teams on HubSpot. → from 0 to clients across the US, Canada, Australia, Europe and the Nordics. → from 0 to a system built with VP Sales from Deel, Meta, Snowflake, Klarna and Revolut. Starting today, we're something bigger... → the world first agency built to clean your CRM AND keep it clean. → we fix your whole HubSpot in 48 hours, done for you. → nothing to build, nothing to manage. 1. Here's what we do for you: → We update your outdated contacts → We fix bad emails and phones → We dedupe your database → We keep it clean, every day, so it never rots again All of this in 48h. And every change is reviewed by our team, approved by you. 2. Why we're doing this: Every company we talked to said the same thing: Nobody owns the CRM. Nobody has the time. And nobody wants to spend a week cleaning data instead of selling. They don't want another tool to babysit. They want specialists who just handle it. So that's what we became. 3. Who it's for: → B2B sales teams on HubSpot and Pipedrive who know their CRM is a mess, and want it fixed without lifting a finger. 4. Who it's not for: → Teams who love wiring up their own tools and have the time to maintain them. For you, we still sell the software, run it yourself. 5. The proof: → 5 CRMs merged into 1 clean HubSpot, after an acquisition → 29% of a 14-year contact base cleaned before it ever entered the new CRM → 31% to 98% of contacts with a valid email, restored. → 79 warm champions surfaced, and manual bounce cleanups gone for good. We clean your CRM in 48 hours. We keep it clean for good. We turn your dead data into warm leads. 6. Curious how bad your CRM is? We'll tell you the exact number, free. → Book your free CRM audit: https://dealmatching.ai/

Grok Bot now catches 100% of the job changes in my CRM. It surfaced 11 warm leads in the last 24 hours... A B2B CRM in 2026 is extremely MESSY. The top 1% of sales teams? They had a HUGE advantage. They knew exactly: - WHO in their CRM just changed jobs - WHEN a champion landed at a new company - WHICH old customer was ready to buy again - HOW to call them before anyone else And 99% of other teams. You, me, everyone else?? We only had 2 bad options: 1) manual: a week of cleaning & it rots again 2) tools: you buy data & it decays in weeks Until now... That advantage just disappeared. We just launched Dealmatching with a SaaS version for sales teams. (the exact result our clients pay us thousands for as an agency now at a fraction of the cost) It handles everything for you: - cleans your whole CRM in 48 hours - update outdated contact, bad phone and email, merge duplicates - catches every job change the day it happens - alerts your rep the moment a contact lands in your ICP - And it ONLY hands your reps leads worth calling. Just like... a top 1% sales team. PRIORITY ACCESS ⬇

If your company scaled its reps and your CRM became a mess, this is for you: every HubSpot expert is wrong about fixing a crm after you scale "just buy more data" "run a big cleanup every year" "hire a revops to own it" "make your reps update their own records" a fintech we help that scaled from 3 to 16 reps ignored all of it - one cleanup - 28,000 contacts fixed - 31% → 98% contacts with a valid email, restored - 36h given back to the sales team each month - still clean 4 months later All of this in 48 hours They didn't: - pay $10k for another one-time cleanup - stack another enrichment tool on top - build a manual process and hope it sticks We just fixed the base correctly and set up a system that keeps it clean nobody else will tell you this but you are WASTING your money While you're running your quarterly "big cleanup" for the third time someone else installed a system that never needs one again We did that for them and now their 16 reps open a CRM that's already correct while everyone else is still "finding time to clean theirs" we just engineered one piece of content correctly and documented the entire process The breakdown shows exactly how we did it and the complete system laid out PRIORITY ACCESS ⬇
