Join us for an evening of deep product insights and conversation with Steve Johnson, CEO of Product Growth Leaders. Most product managers aren’t struggling because they lack frameworks, data, or AI tools. They’re struggling because they’re talking to the wrong people. Instead of learning directly from customers, they rely on second-hand input—sales requests, executive opinions, support tickets, dashboards, and now AI-generated summaries of all of it. The result? Noise. Misalignment. And products that look good on paper but miss the market. AI can process more data than you ever will—but it can’t replace direct human understanding. It can’t see hesitation. It can’t hear what’s not being said. And it certainly can’t build trust with a customer who doesn’t believe you yet. That’s where product managers have an advantage—if they choose to use it. In this session, you’ll learn how Customer Conversations cut through the noise and become your most powerful differentiator. Not as a research technique, but as a leadership behavior that builds market insight, credibility, and better decisions. Through real stories and practical methods, you’ll learn how to: • Talk to the right people at the right time in the product lifecycle • Ask questions that uncover real problems • Validate ideas before you build them Because in a world where AI can generate answers at scale, the product manager who understands customers firsthand becomes the one who asks better questions—and makes better decisions. AGENDA 6:00 - 6:30 pm: Welcome and Registration. Refreshments provided. 6:30 - 7:00 pm: Talk by Steve Johnson (CEO at Product Growth Leaders) 7:00 - 7:15 pm: Q&A 7:15 - 8:00 pm: Networking ABOUT THE SPEAKER Steve Johnson is a product success coach focused on removing the chaos from product planning. He uses modern methods to guide product teams from idea to market in only a few weeks. Steve has trained tens of thousands of product professionals in his career. He is a former instructor and vice president at Pragmatic Institute and the chief architect of the popular Quartz Open Framework.

**NEW MEMBERS or 1st TIME EVENT GO-ERS** Before attending your first event, please take a moment to understand how our dinners work and what we ask of members. → **[Learn how DC Metro Dining works](https://tinyurl.com/Landing-Page-DC-Metro-Dining)** **RSVP CUTOFF (i.e. Final Change Your Mind if Registered YES)** → **RSVP Cancellation Cutoff for this Event is Saturday 10a, 5/2**. (*Late Cancel applies after this, repeat occurrences can impact membership*) I'm in the mood for a great French bistro-style dinner in DC. We are heading to **Amélie** in Logan Circle, known for its wine program and classic French fare in a relaxed, modern setting. **FOOD**: Modern French Bistro, well-executed. Amélie focuses on approachable French bistro cuisine with an emphasis on small plates and shareable dishes. Diners often highlight escargots, steak frites, and duck confit as reliable standouts, along with mussels prepared in classic broths. Cheese and charcuterie boards are frequently ordered to start, and lighter items like salads and tartines round out the menu for those looking for a less heavy meal. Executive Chef Anthony Lemortellec, a Parisian who has worked with the legendary chef Alain Ducasse in Paris, moved over from Boqueria where he was Chef. The wine program is a major draw, with a broad French-leaning selection and rotating options by the glass. Cocktails are quite good but the focus here is wine-driven, which pairs well with the menu structure. Most members should expect total spend to land roughly in the 55 to 85 dollar range depending on beverage participation. → **Explore Amélie's menu:** **[https://www.ameliedc.com/dinner](https://www.ameliedc.com/dinner)** **SPACE**: Cozy, stylish interior with a mix of bar seating and dining tables. Expect a lively, social atmosphere with moderate noise, especially on a Saturday evening → **Visit the restaurant site**: [https://www.ameliedc.com](https://www.ameliedc.com) - Tax/Tip combo is our required 30% tax/tip policy (see the FAQs for more details). - Limited to 8 slots. See you there! JoeN **CLOSEST METRO**: - **U Street–African-Amer Civil War Memorial–Cardozo station** (Green, Yellow) is the closest stop. Walk south via 14th St NW or Vermont Ave NW. The walk is about 15–18 minutes. - **Dupont Circle station** (Red) is also nearby. Walk east toward 14th St NW, then south. The walk is about 16–20 minutes. - For directions using the Metro, try using the Plan a Trip feature at the WMATA website ([click on your preferred Metro station](https://www.wmata.com/rider-guide/stations/index.cfm) then at the Station page level click "Plan a Trip". **PARKING**: Street parking in this area can be difficult on weekend evenings. Several paid garages are located within a few blocks along 14th Street and nearby side streets. Plan accordingly. ***Attendance Notes:*** - **If you RSVP “YES,” please commit to showing up***\*\*.\*\ *With 5,400+ members and limited seating, we can’t afford no-shows. It’s not fair to other members or to our relationship with the restaurant.* - ****New Members / 1st Timers:*** Trying to get a slot? Join the Waitlist and check back frequently: spots (*often open up before Noon on the day of the event. You may also receive midweek confirmation emails to reconfirm your RSVP, so please check your Meetup DMs inbox).* -****Billing Reminder - Add 30% for tax and tip to your food and drink total.*** This is part of our group’s expectations and helps smooth out service with the restaurant.

She develops the kind of leaders people actually want to follow. **Lillian Morales-Laster** SVP Human Resources Director at United Midwest Savings Bank and Executive Director of the Empowering Latinas Leadership Academy (ELLA). Lillian has spent her career combining her passion for equity and inclusion with her experience in human resources to lead teams and organizations in the development of supportive work environments.
