Who We Are
Your partner from to predictable revenue.
Phase 4 Consulting is a business growth consultancy for startups and small businesses. We combine business consulting, website design, SEO & AI search, and sales leadership so strategy actually becomes customers and revenue — not a plan that sits in a drawer.
Everything under one roof
Business consulting, websites, SEO, and sales from one senior team — instead of juggling five vendors who never talk to each other.
Outcomes, not deliverables
We're measured by your growth — revenue, qualified leads, and search rankings — not by the page count of a report.
Senior-level partnership
You work directly with a senior partner who is accountable for results from first strategy to measurable revenue.
Client Testimonial
Seth knocked it out of the park. Our website came out better than I expected, and he was incredibly easy to work with throughout the whole process. I also needed a few other things done for a separate project, and he had everything back to me in less than a day. Great communication, great work, and someone I'll definitely be using again.

Meet the Founder
You work directly with the person doing the work.
Seth Hartness
Founder & Principal Consultant
Phase 4 is founder-led. When you work with us, you work directly with me — not a junior team or an account manager. I build the websites, set the strategy, and pick up the phone. Every engagement gets full-stack attention — design, technical SEO, branding, and the operational pieces most agencies leave for you to figure out on your own, from compliance documentation to platform setup. I started Phase 4 to give small businesses and founders a senior, hands-on partner across the whole growth stack — websites, SEO, strategy, and sales — grounded in faith and measured by real results.
Outside of work, family is everything. My fiancée Maeve and I have been together almost eight years, and our son Theo — who's on the autism spectrum — is the light of our world. Raising Theo has shaped how we show up for the people we work with: with patience, honesty, and real care. In my spare time, you can catch me in the woods or at a local fishing hole — bowhunting's my favorite, hands down.
