Lillian Pierson, P.E.

WHO I WORK WITH

I'm Lillian Pierson, P.E., founder of Data-Mania and a fractional CMO for data, AI and B2B SaaS startups. I work with companies from early-stage funded to $6M ARR, where the product is technical and the buyer is often technical too.

That range covers three different jobs. Between $100K and $500K the work is positioning and the first repeatable acquisition path. Between $500K and $2M it is building repeatability, so one validated ICP and one message that holds across channels. Between $2M and $6M it becomes GTM engineering, where I automate what already converts.

WHY AN ENGINEER RUNS MARKETING DIFFERENTLY

I'm a licensed Professional Engineer who became a marketing executive. That combination is the whole offer. I think in systems and instrumentation rather than campaigns, so every recommendation I make ties back to a number you can watch move.

Most advisors hand you a strategy and leave you to run it. I build the system and stay hands-on while we do, because the gap between a plan and its execution is where most growth quietly dies.

RESULTS FROM RECENT ENGAGEMENTS

SheetRocks, a seed-stage financial SaaS product with a five-person team, went from 5 users to 1,100 users in 90 days and booked first revenue inside 60 days on self-serve checkout at $59.95 per month.

Future Sight AR, an industrial AR company, ran the founder-led go-to-market playbook I engineered to a $100,000 contract from a single LinkedIn post, along with a tenfold increase in site traffic.

SingleStore, a Series A database company, generated 1,100 qualified leads at roughly $50 per lead over 10 months, in a category where the cited average cost per lead was $595.

CREDENTIALS

I've written 12 books with Wiley, including multiple editions of Data Science For Dummies, and built 14 expert-led AI courses for LinkedIn Learning and O'Reilly. I've trained more than 2 million professionals, and I've grown an audience of over 750,000 organically without paid advertising. My client work spans Amazon, Dell, Intel, IBM and BMC alongside fast-growing startups. I'm a former Microsoft Regional Director.

WHEN NOT TO CHOOSE ME

I'll be honest about fit. If you want a paid-ads specialist, a brand-storytelling agency, or someone to run a single channel in isolation, I'm not your best match. If you're pre-product with no revenue signal yet, I'm early for you. I'm for founders who want a whole growth system engineered and handed off.
