authentisign.comAuthentisign is a real estate-focused e-signature solution built specifically for agents, offering unlimited document signing at 13 dollars per month.
The verdict
Authentisign is an excellent budget choice for agents who need reliable e-signatures without extra features. Best for those already using zipForms who want to stay in the Lone Wolf ecosystem.
01 — Overview
What Authentisign is, and isn't.
Authentisign is an electronic signature platform designed specifically for real estate professionals. Part of the Lone Wolf Technologies family (which also owns zipLogix/zipForms), Authentisign focuses on delivering simple, reliable e-signatures without the complexity of full transaction management.
The platform is popular with agents who want a straightforward e-signature tool without paying for features they do not need. Authentisign integrates well with zipForms and other Lone Wolf products, making it a natural choice for agents already in that ecosystem. Lone Wolf also launched Inkless in August 2025, an API-first e-signature product, and opened its API Portal in February 2026, signaling a broader push into developer integrations.
While Authentisign lacks the brand recognition of DocuSign or the transaction management features of Dotloop, it offers competitive pricing and a focused feature set. It is particularly appealing to agents who use zipForms for document creation and just need a reliable way to collect signatures. Lone Wolf has secured major association partnerships, including a 5-year deal with FMLS (60,000 members) and an expanded 5-year partnership with the California Association of REALTORS (190,000 members).
