Built by a Clinician

I built Sleft Signals because I watched attending physicians struggle to grow their practices while paying agencies thousands for leads that never converted. The answer was always the same: the best patients come from other providers who trust you.

Agencies Burn Your Budget. Referrals Compound.

Marketing Agencies

$2-5k/month for Facebook ads that send tire-kickers who ghost after the first visit. Zero integration with your local community. You compete with every practice in your city.

Provider Referrals

Patients arrive pre-qualified and trusting. The ortho 2 miles away sends you 10 post-ops a month. The PCP down the street refers every MSK complaint. Zero ad spend. Relationships that compound.

We Do The Work For You

No networking events. No cold calls. We find the providers, you make the connection.

We Find Them For You

We scrape and verify local providers in complementary specialties. You just show up and connect.

Hyper-Local Matches

Providers within 5-10 miles of your practice. Same community, same patients, easy referrals.

Mutual-Fit Only

A chiropractor needs PTs. A PT needs orthopedic surgeons. We match specialties that actually refer to each other.

Referrals That Make Sense

We match specialties that naturally refer to each other. Your patients become their patients, and vice versa.
