I build the data pipelines, enrichment, and cold-email infrastructure that turn untapped audiences into booked meetings, with multiple data sources, automation, and AI.
Tools I work with:
Growth usually breaks in one of two places: nothing is coming in, or nothing behind the scenes can handle it once it does.
Hours disappear into prospecting, list cleanup, and copy-paste outreach. Your time — and your team's — is worth more than work a machine does better.
Most lead lists rot 30–40% within a year. Every bounce chips away at your sender reputation. Verified, enriched data fixes that at the source.
Your process lives in your head, a Slack thread, or nowhere at all. New hires can't ramp, and the moment you step away everything stalls.
The setup that handled 5 clients falls apart at 25. Without structure, more revenue just means more chaos, faster.
One fills your calendar. The other makes sure your business can handle what lands in it.
The automated engine that keeps your sales calendar full, so your time goes into closing instead of prospecting.
I find and verify the right accounts and people for your offer. Clean, accurate, ready to reach.
Domains, inboxes, sequencer, enrichment, CRM — set up and wired together so the whole thing runs on its own.
Warmup, authentication, and sending limits configured so your emails actually reach inboxes — not spam folders.
You get the keys to a fully functioning outbound engine. It's yours to keep, not rented from me.
The operational backbone — CRM, SOPs, workflows — that keeps your business standing once the leads start coming in.
I map how work actually happens today — your pipeline, handoffs, tools — and where things quietly break.
Built or rebuilt around how you actually sell — not a generic template you'll abandon in three months.
Every process, script, and decision documented in one place your team will actually open — not buried in a doc no one reads.
Your team gets trained on the system, not just handed a link. Readiness, not just documentation.
No generic package pitched on a first call. We figure out what you actually need, then scope it.
A real conversation about what's broken, what you've already tried, and what success looks like six months out. No pitch deck, no pressure.
One clear recommendation — outbound, operations, or both — built around what you told me. Not a menu of tiers.
I build inside the tools you already use, or help you choose the right ones. You see progress in weeks, not a black box for months.
You walk away owning a working system and a team that knows how to run it — not a dependency on me.
Real campaigns. Real results. Here's what I've built.
Approach: Scraped LinkedIn Ads with Apify, then qualified which of those companies were B2B.
Why it worked: A personalized first line referencing their actual LinkedIn ad activity made the outreach hyper-relevant.
Approach: Scraped the Slicelife and Toasttab restaurant directories, then used Prospeo to find the emails associated with each domain and reverse prompts to find job titles.
Why it worked: Restaurant prospects are rarely found on LinkedIn or Apollo, and these inboxes are barely touched by cold email, so the people behind them are far more open to it.
Approach: Scraped law firms with Serper, split them into three segments with three different messaging angles, and scraped their actual Google reviews with Apify.
Why it worked: Each of the three segments (under 80 reviews, one to two bad reviews, and 100+ reviews) had a completely different pain point, so each one got completely different messaging.
Approach: Scraped hotels from Apollo, directories, and Google Maps using SerpAPI, then referenced their OTA listings.
Why it worked: The emails referenced their OTA listings (Booking.com and the like) and offered to reduce their commission dependency through direct WhatsApp bookings.
Approach: Scraped software companies offering free trials from Product Hunt, GetLatka, GetApp, Toolify, and SourceForge, then used Pandamatch and Similarweb for traffic data.
Why it worked: An AI prompt checked whether they actually offer a free trial, and companies with free trials want to convert those users into paying customers.
Approach: Scraped software directories such as Crunchbase, Product Hunt, GetLatka, GetApp, Toolify, and SourceForge, then ran AI prompts to check for free trial offerings.
Why it worked: It targeted companies with a specific headcount in their phone and customer support departments, combined with heavy website traffic.
A founder on what it's like working together
What colleagues and clients say about working together
Founder @ Growth Engine X
Slack · December 2025
Founder @ oneaway.io
"One of the best hires I've ever made. I recommend Marielle to anyone and everyone under the sun that wants an A player on their team."
Founder @ group-venluto.com
"The best GTM member we've ever had. We brought in 8 clients in just 2 months with Marielle's help. We didn't have to handle the campaigns at all, and she kept us updated daily, providing support that went far beyond simply managing the campaigns."
Founder @ Prospeqt.co
"Working with Marielle made everything feel lighter. You give her the context, tell her the outcome you want, and she just gets it done.
She picked things up fast, Clay workflows, data scraping methods, automation, and kept it all running smoothly. A lot of moving parts, but she made the process feel simple.
She's one of those people you can count on. That alone makes a huge difference when you're building outbound systems at scale."
Founder @ coldlabs.ai
"Marielle is one of the hardest-working people I know. You can give her an incomplete task and trust that she'll figure it out and deliver something even better than expected.
She doesn't just do the work, she finds ways to improve it. That kind of reliability, initiative, and problem-solving capabilities are extremely rare. Hands down - the best in the game."
Founder @ Dreamwell.ai
Founder @ pointerstrategy.com
"Elle was an incredible asset to our team and our clients. She consistently went over and above to make sure her work was done to the best of her ability and was extremely coachable in every way.
Elle has a very broad skillset which was greatly needed in our startup with her talking on more than her regular tasks, but also the ones that had 'no home'."
I'm Marielle, a GTM Engineer and outbound specialist. If you're a founder pushing for pipeline or a team that needs systems that actually scale, I bring the technical execution to make it happen.
From Claude Code and Codex workflows to cold email infrastructure and full outbound automation, I handle the build so you can focus on closing. Custom scraping, multi-source enrichment, AI qualification, deliverability, CRM wiring — I work inside the stack, not around it.
I don't just recommend tools. I build inside them, ship them into production, and hand them over working — because a system that only runs while I'm in the room was never a system.
