The research behind every serious decision.
Schedule a Consultation →Most strategy advice is either too abstract to use or too cautious to matter. We built Louisburg the other way: concrete, opinionated, and on the hook for whether it works. We operate across business and government, and we take our name from Louisburg Square, Beacon Hill's quiet center of gravity for the better part of two hundred years.

Louisburg Square sits at the heart of Beacon Hill: a private garden surrounded by brick townhouses that have served as the quiet center of Boston's civic, political, and business establishment for nearly two centuries. It is a place where influence has always been exercised with discretion, where strategy unfolds behind closed doors, and where lasting institutions are built.
Louisburg Strategies carries that tradition forward. We are a strategic advisory firm built for leaders making complex, high-stakes decisions who want a partner to help them get it right.
Our difference is fluency across sectors. Most firms pick one lane and stay in it. We move between business and politics, and each makes the other sharper. A corporate turnaround goes better when you know how to build a coalition. A campaign runs tighter with real operational discipline. The best strategies live at the intersections.
Sterling Rettke founded Louisburg Strategies on a conviction that serious strategy shouldn't be reserved for those who can afford a large firm's retainer. What began as a focused practice has grown into a firm advising leaders across business and government.
His career spans every level of American politics. He has worked presidential, federal, and state campaigns, including the 2020 effort to elect President Biden. He has served as an organizer, fundraiser, campaign manager, and senior consultant.
That political fluency informs a broader advisory practice. Sterling has guided companies through operational turnarounds, modernized aging systems, and counseled early-stage founders, bringing the same rigor to a boardroom that he brings to a campaign.
Four ways we help, across business and politics.
Find out why a business is losing money and fix it. We took one company that had been in the red for three years and made it profitable again, without a single layoff.
Rebuild the outdated website, migrate the point-of-sale, automate the busywork. We moved a restaurant from Square to Toast, reworked the menu, and added dynamic pricing. Same-store sales up 32% year over year.

Opposition research for campaigns, competitive intelligence and due diligence for business. Deep digging to find what others miss, before you need it.
We start with analysis, not assumptions. Stakeholder interviews, data, market research, competitive benchmarking. The output is a clear-eyed view of where you actually stand.
Options grounded in evidence and stress-tested against your reality. The deliverable is a plan with priorities, milestones, and named owners.
