What OpnSesame does
Opn Sesame, LLC is a Washington, D.C.-domiciled SaaS company that operates a peer-to-peer (P2P) text messaging platform marketed to political campaigns, nonprofit organizations, and commercial businesses. The platform enables direct one-to-one SMS conversations between an organization's representatives and its supporters, constituents, donors, or customers, with two-way reply capability. Core use cases cited include get-out-the-vote (GOTV) mobilization, fundraising, lapsed donor re-engagement, event signup and turnout, app downloads, email opt-in capture, and direct-to-consumer sales, with MMS video messaging supported for branding and persuasion campaigns.
The product suite consists of the P2P Texting Platform and SMS Short Code Platform as core products, plus an "Idiot-Proof Dashboard" back-end and a P2P-to-API-to-SMS Integration module. The integration module connects to major U.S. SMS short code providers via API so customers can text their existing email or supporter lists, capture affirmative opt-in replies via keyword responses, and automatically synchronize confirmed contacts back into their SMS short code contact files. Social login (Facebook, Twitter, LinkedIn, Google) is used for authentication on the dashboard. The architecture is a typical SaaS web application with carrier-routed SMS messaging rather than a built-in telco stack.
The business model combines recurring SaaS subscription fees with usage-based SMS messaging charges (standard carrier texting rates apply for messages sent and received), plus optional add-on services subject to separate agreements. Pricing is not publicly disclosed; the Terms of Use indicate fees are posted in-product and may be changed on 30 days' notice. Go-to-market is sales-led direct outreach via the company website contact form, with a stated reseller/white-label capability letting enterprise customers allocate the service to their own end users (call centers, universities, B2B clients, political campaigns). No funding rounds, named customers, certifications, awards, or leadership team are disclosed.

OpnSesame competitors and assessment
Company assessmentDirect peers
- CallHub: Direct competitor offering P2P texting, voice broadcasting, and contact-center tools for political campaigns, nonprofits, and advocacy groups. CallHub serves the same primary verticals (GOTV, fundraising, volunteer mobilization) with overlapping SMS and API capabilities.
- Hustle: Direct peer in P2P texting for political campaigns, nonprofits, and advocacy organizations. Hustle is one of the most established competitors in the peer-to-peer political texting category and competes head-to-head with OpnSesame for the same campaign and nonprofit customers.
- Tatango: Direct competitor in SMS marketing and mass-texting platforms serving political campaigns, nonprofits, and commercial customers. Tatango's focus on religious organizations and political clients overlaps directly with OpnSesame's primary customer segments.
- SimpleTexting: Direct peer offering an SMS marketing platform with mass texting, two-way conversations, and short-code services. Targets small businesses, nonprofits, and political campaigns — overlapping significantly with OpnSesame's commercial and nonprofit segments.
- GetThru (formerly Relay): Direct peer providing P2P texting and dialer tools for political campaigns, labor unions, and advocacy organizations. One of the original entrants in the P2P political texting space with strong overlap to OpnSesame's campaign-targeted offering.
- EZ Texting: Established SMS marketing platform serving SMBs, nonprofits, and political campaigns with bulk SMS, two-way messaging, and short-code capabilities. A more generalist peer competing for the same commercial and nonprofit texting customers.

- Spoke: Direct P2P texting peer focused on helping organizations (especially nonprofits and advocacy groups) text-enable their supporter lists. Operates in the same grassroots outreach and SMS opt-in-building category as OpnSesame.
Broad incumbents
- Twilio: Broad incumbent providing the underlying communications APIs (SMS, voice, short codes) on which many P2P texting platforms are built. Twilio competes indirectly by enabling competitors and offering higher-end messaging products to enterprise customers in the same verticals.
Emerging players
- Sakari: SMS marketing platform focused on two-way texting, short codes, and CRM integrations. An emerging player in the same category that overlaps with OpnSesame on commercial customers and message-list-building workflows.
