I’m Leslie Cobb, founder of Proposal Masters and an executive proposal writing and capture leader with more than 20 years of experience guiding federal, state, local, Medicaid-adjacent, healthcare, telecommunications, and public sector organizations through complex, high-stakes procurements. I currently serve as Senior Proposal Manager and Lead of Government Business Development & Capture Management for AT&T Business’s Public Sector & FirstNet division, where I direct proposal strategy that has contributed to more than $4 billion in awarded contracts — spanning cybersecurity, mobility, network modernization, and mission-critical IT solutions for customers including DISA, the U.S. Courts, FCC, Navy, and DLA. I founded Proposal Masters in 2003 to bring that same caliber of leadership to clients directly. Rather than teaching a class and handing you a junior writer, I’ve hand-picked a team of proven Subject Matter Experts — real practitioners, not generalists — who bring deep functional expertise to every engagement. Together, we lead full-lifecycle capture and proposal support: RFP analysis, compliance matrices, writing, production, and final submission. As a consultant, I supported winning AT&T bids valued at more than $150 billion between 2015 and 2020, contributing to a documented 95% win rate across 1,000+ proposal efforts. Before founding Proposal Masters, I held senior proposal and production leadership roles at NCI and Harris IT Services, building and leading teams that delivered 100–150+ proposals annually across multi-billion-dollar pipelines. I’m APMP Foundation certified and Shipley-trained, and I bring hands-on expertise in AI-enabled proposal workflows — including Microsoft 365/Copilot, ChatGPT, Visible Thread, and PWin.ai — to every client engagement, improving compliance traceability, proposal quality, and team efficiency. No project is too big or too small. Let’s help you reach your next level.

Technology Transformation Executive | AI Strategist | Founder of Digital Wave Inc. & SermosGo I help organizations bridge the gap between people, technology, and artificial intelligence. After more than 30 years leading technology transformation, cybersecurity, software quality, and digital innovation for government agencies and Fortune 500 organizations, I founded Digital Wave Inc. to build AI solutions that solve real business problems. My work combines executive leadership, emerging technology, and practical business strategy to help organizations modernize, grow, and prepare for the future. As the creator of SermonsGo, I am helping churches and faith-based organizations transform a single sermon into searchable archives, study resources, short-form video content, and social media engagement using responsible AI. My philosophy is simple: AI should assist people, not replace them. People know me as The Bridge Builder because I connect people, ideas, businesses, and technology in ways that create opportunities for everyone involved. Whether I'm advising executives, mentoring entrepreneurs, speaking on AI, or building new technology platforms, my focus is always the same: helping others move from where they are today to where they want to be tomorrow.
