Best Alternatives to Mantle SAFEs in 2025
Mantle SAFEs simplifies the process of issuing and signing SAFEs for startups, offering free Y Combinator templates and built-in e-signatures without the need for DocuSign. However, as your startup grows, you may need more comprehensive equity management, cap table administration, or investor relations tools. Below are the best alternatives to Mantle SAFEs, each with unique strengths for different stages and needs.
Carta
Carta is the industry standard for cap table management and equity administration. It offers robust SAFE issuance, electronic signatures, and automatic cap table updates, but with a more extensive suite for fundraising, valuations, and employee equity plans. Ideal for startups that plan to scale and need institutional-grade compliance and investor reporting.
Pulley
Pulley is a modern, founder-friendly alternative that provides free cap table management for early-stage startups. It supports SAFE creation and e-signatures, and its pricing scales with your company's growth. Pulley is known for its intuitive interface and transparent pricing, making it a great choice for founders who want a simple but powerful tool without hidden fees.
Capdesk
Capdesk (now part of Carta) is a European-focused equity management platform that excels in handling SAFEs, ESOPs, and shareholder communications. It offers automated cap table updates and e-signature workflows, with strong compliance for international regulations. Best for startups operating in Europe or with cross-border investors.
AngelList
AngelList (now AngelList Venture) is a platform that combines fundraising, syndicates, and equity management. It allows you to issue SAFEs with built-in e-signatures and automatically updates your cap table when investors sign. It's particularly useful if you're raising via AngelList syndicates or want to streamline investor onboarding and communication.
DocuSign + Excel/Sheets
For founders who prefer a DIY approach, using DocuSign for e-signatures alongside a spreadsheet for cap table tracking is a low-cost alternative. This works if you have very few SAFEs and don't need automation. However, it requires manual updates and lacks the legal template validation that Mantle provides, so it's only recommended for the simplest cases.
Founderpath
Founderpath is a newer tool focused on SAFE and note management for early-stage startups. It offers free SAFE templates, e-signatures, and cap table tracking, with a clean user experience. It's a direct competitor to Mantle, but with additional features like investor CRM and fundraising analytics, making it a good choice for founders who want more than just document signing.
Zebra (by Carta)
Zebra is Carta's free tier designed for early-stage startups. It allows you to issue SAFEs, collect e-signatures, and maintain a cap table at no cost. It's a great alternative if you want the reliability of Carta's infrastructure but aren't ready to pay for premium features. Zebra seamlessly upgrades to Carta's paid plans as your company grows.
While Mantle SAFEs is an excellent free tool for issuing and signing SAFEs, the best alternative depends on your startup's stage and needs. For comprehensive equity management and scalability, Carta or Pulley are top choices. For European operations, Capdesk is ideal. If you're raising via AngelList, its integrated platform is convenient. For a free but reliable option, Zebra by Carta offers a solid foundation. Ultimately, consider your budget, growth trajectory, and whether you need additional features like investor relations, ESOP management, or international compliance.
