合伙股权分配，股权比例设计，控制权把控
by Andra
老板，你是否存在这些股权问题却不知道怎么更好的解决？
1、想给公司导入股权激励，但不知道怎么分？分给谁？分多少？
2、公司到达一定规模后，高管纷纷离职，另立山头怎们办？
3、工资涨了又涨，绩效变了又变，但依然没有激情与动力……
4、不懂股权设计，公司治理不当，导致股权结构混乱，股东不和
5、如何让员工动力十足，公司业绩蒸蒸日上.....
6、各部门自动化运作，解放老板...
【为什么】您苦心培养的人才总在流失，出去就成为您的竞争对手？
【为什么】车间里的跑、冒、滴、漏比利润还要多，员工却视而不见？
【为什么】开10个店赚钱，20个店保本，30个店就亏钱？
【为什么】营销费用、管理费用越来越高，层层审批也无济于事？
【为什么】薪酬涨了又涨，绩效变了又变，问题还是无所改善？
【为什么】代理商赚钱，您的直营团队却在大面积亏损？
【为什么】苦苦奋斗多年，只见年纪大，不见公司大！只见白发多，不见利润多！
两天课程为你企业解决：
✅1.团队股权激励设计
（解决员工流失率高，员工没有激情，缺少有效的激励方法和系统，薪酬系统不规范，缺少方法和执行标准。）
✅2.绩效考核流程指标
（解决团队不接受公司的战略目标，上下达不成一致，部门反应绩效考核指标不合理，绩效考核难以实施，没有业绩推动手段。）
✅3.股权、战略架构梳理优化
（解决企业定位模糊，战略缺失；股东人数多，无实际控制人，股权结构有隐患。）
✅4.股权架构设计
（解决公司想要整合上下游，不知道如何操作，估值不合理，业务流程复杂，执行效率低下。）
✅5.合伙股权分配，股权比例设计，控制权把控
（解决毒品股东，设计股权结构，完善公司治理架构。）
✅6.财税，法律，商业模式
（解决税务风险，商业模式创新设计。）
✅7.上市规划
（董事高管，三年之内不能变动，否则不能上市，所以一定要做股权激励）
华一世纪——《公司控制权与股权激励》——【为企业系统解决股权激励、股权分配、股权架构、上市重组、顶层布局、绩效薪酬、章程修改】全国开课，打造公司内部合伙人，帮您在公司内部建立一套让员工为自己干的机制，为企业发展保驾护航！
