SparkRM is the CRM reimagined for real relationships. It remembers what matters, finds meaningful reasons to reconnect, and helps you write the message. AUTHENTICITY IS YOUR SUPERPOWER It’s why people remember you. Why they trust you. Why they choose you. But staying connected to 200, 500, or 1,000 people is hard. People change jobs. Companies get acquired. Favorite teams make the playoffs. Kids graduate. Markets shift. Big things happen. Relationships slip through the cracks—not because you don’t care, but because no one can keep up with everything. SparkRM helps you stay connected to the people who matter, authentically and at scale. SPARKRM FINDS THE REASON TO REACH OUT Tell SparkRM what you know: “Mike is a huge Bills fan.” “Sarah works at a regional bank.” “Chris owns a construction company and loves offshore fishing.” SparkRM organizes the details you save. For contacts you select for AI help, it can turn that context into timely, specific reasons to reconnect. When relevant news is available, Spark Pro and Spark Power can connect it to the people who may care: a favorite team makes the playoffs, a contact’s company announces an acquisition, or a story affects their industry. SparkRM filters out weak or repetitive ideas and brings the strongest opportunities to your Today list. Not just because you haven’t “touched” someone in 90 days. Because there may be something genuinely worth talking about. AND THEN SPARKRM WRITES THE TEXT Knowing who to contact is only half the battle. SparkRM helps with the why and the “What do I say?” Instead of “Hey Mike, just checking in,” SparkRM might suggest: “Mike! The Bills are playoff bound! I know you’ve gotta be fired up. Are you making it to any games?” Relevant. Personal. Timely. Human. SparkRM drafts the message. You review it, make it yours, and choose whether to send it. SparkRM never sends messages automatically. YOUR RELATIONSHIPS HAVE CONTEXT. YOUR CRM SHOULD TOO. Traditional CRMs store contacts and tell you when to follow up. SparkRM helps you understand why today might be the right day. Add context by typing, or use supported voice features with a paid plan. SparkRM organizes notes, interactions, reminders, important dates, work details, interests, and relationship connections to improve suggestions and conversation preparation. WHAT SPARKRM HELPS WITH • Import contacts from your phone or a CSV • Keep unlimited contacts on every plan • Capture notes, reminders, interactions, and important dates • See birthday and reminder nudges for every contact • Get a small, curated Today list • Review and edit every draft before sending PERSONAL AT SCALE SparkRM is built for realtors, advisors, contractors, photographers, founders, entrepreneurs, community builders, and anyone whose success depends on relationships. Competitors can copy your playbook. They can’t copy your personality, relationships, or ability to connect. That’s your superpower. SparkRM helps you use it. FREE AND OPTIONAL PAID PLANS SparkRM’s free tier includes unlimited contacts and imports, birthday and reminder nudges for every contact, AI help for up to 5 selected contacts, and up to 1 curated AI suggestion per day. Spark Pro and Spark Power are optional auto-renewable subscriptions requiring a separate Apple In-App Purchase. Spark Pro includes up to 100 AI-enabled contacts, 5 curated AI suggestions and 3 context questions per day, news-grounded check-ins when relevant news is available, and additional AI and voice usage.
