Bio
Hey, I'm Lena! 👋 I've worked as a product manager in tech for 6 years and have been an entrepreneur since Feb 2020, launching anything from SaaS products to self-publishing a book to testing online marketplaces to running a successful online coaching business. **LINKEDIN + PERSONAL BRANDING** If you're looking for a way to show up authentically on LinkedIn while getting dream clients, I can help. I've taught 100+ business owners my simple Triangle Method for landing clients on LinkedIn & have gotten 8M+ views on TikTok for my content about LinkedIn. **VIDEO CONTENT CREATION** If you're looking for help with creating or refining your short-form video content & monetizing it, I can help. My short-form video content has filled my sales pipeline in my coaching business for years & I've even created videos for GrowthMentor! **PRODUCT MANAGEMENT** If you're looking for help with creating a roadmap, prioritizing features, working with developers, managing stakeholders etc. as a product manager, I can help. For 6+ years I worked as a PM in 3 different companies and know first-hand how challenging this role can be. **CHATGPT** If you're looking for ways to integrate ChatGPT into your daily workflow, improve your prompting skills or find new use cases for ChatGPT, I can help. I use ChatGPT on a daily basis to help me brainstorm ideas, do analysis, create content, etc. and love helping others leverage this powerful tool better.

Expertise
Artificial intelligence
I'm well-versed in using ChatGPT to brainstorm ideas & strategies, do research, create content or analyze situations for insights (e.g. sales conversations, employee relations, business decisions.) I can help you with improving your prompting in ChatGPT, refining the responses you get & implementing those responses in a way that's useful and natural.
Content marketing
Been creating content online since 2020 (LinkedIn, IG, TikTok, YouTube, blog posts, newsletter). Also been a freelance writer for the product management niche, writing SEO-optimized blog posts for companies like Userpilot, Arc.dev & Productboard. My online content has gotten millions of views over the years & I've also been published by Start It Up, the largest publication on Medium, and Product Coalition, the world's largest independent product management community.
Copywriting
I'm a writer at heart and believe that every kind of modern web writing has elements of copywriting woven into it — it's how you get attention online these days. I can help you identify what tweaks you need to make to your copy to make your customers heard. Or identify the research you need to do to get the voice of your customer into your copy. I've written for companies like Userpilot, Arc.dev & Productboard.
Idea validation
I ran an innovation team as a product manager for 8 months & built a hypothesis-based framework for rapidly validating new product ideas. I then tested 6 product ideas (2 of which were marketplaces) as an entrepreneur over the course of 19 months. I've also mentored at a university accelerator where I helped young founders successfully validate (in invalidate!) the ideas behind their startups.
Mindset coaching
I've battled imposter syndrome, burnout, business failures & business pivots as an entrepreneur. My specialty is continuing to push before you see success and getting back up after failure and learning from it. I know how to help you manage your own psychology so you can continue to move quickly both as an employee & an entrepreneur.
Personal branding
I've built a personal brand on multiple social media platforms (LinkedIn, IG, TikTok) as well as through in-person networking, and have also helped 100+ experts create a strategy for their personal brand. I can help you pinpoint what's unique about you & show up in an authentic way so your online presence feels like a true extension of you.
Product management
I was a product manager, mainly in B2B tech, for 6 years and can help you figure out the 20% of effort you need to leverage to get 80% of your results. Working with engineers, prioritizing features, managing stakeholders, motivating your team in times of low morale... I've been through it all and know how to help. My product management experience is mainly in Fintech and in entrepreneurial startup-like teams.
Social media
I've built a personal brand on multiple social media channels (LinkedIn, IG, TikTok) and have built a successful online coaching business where 100% of my clients came from social media. I've also helped 100+ business owners get clients on social media as a business coach. One of my specialties is LinkedIn — how to optimize your profile, grow your network, and post content that positions you as a thought leader or gets you clients for your service business.
User research
I've worked in an innovation team as a product manager, using user research to launch new product ideas into the market. I've also used user research as an entrepreneur to launch multiple products and services and monetize them. I can help you come up with a strategy to gather user research, analyze it & use it to make decisions around what to launch & how, including how to market it.
Venting frustration
I have made SO many mistakes both in my career and during my recent entrepreneurial journey due to sheer frustration. I can be your objective sounding board and help you channel your frustration into an effective and measured approach to dealing with whatever is making your blood boil.
