Mimiran markets itself directly as "the anti-CRM for solo consultants, coaches, and fractionals" — a tool built in reaction to the same problem most independent consultants run into with traditional CRMs: setup that takes weeks, fields that assume a sales team, and a vocabulary lifted from enterprise software instead of consulting practice. Mimiran's pitch is "minutes, not weeks," and for a lot of solo practitioners, that promise alone is the whole sale.
Retainer starts from the same complaint. We think most CRMs are wrong for consultants too — just not for quite the same reason, and the fix we landed on is different.
Where the two products agree
Neither Mimiran nor Retainer wants you configuring pipeline stages, deal probabilities, or lead scoring rules before you can add your first client. Both reject the idea that a solo consultant or small firm needs the same software infrastructure as a 40-person sales org. If your last CRM evaluation ended with you closing the tab because the onboarding wizard had eleven steps, both of these tools were built for you specifically.
Where they diverge: simplicity as the goal vs. simplicity as the starting point
Mimiran's anti-CRM positioning treats simplicity itself as the product — fewer fields, faster setup, less to learn. That's a genuinely good fit if what you need is a lightweight way to keep track of contacts and follow-ups without the weight of a full system.
Retainer treats simplicity as a starting condition, not the finish line. We stripped out the same sales-team vocabulary Mimiran does — but instead of stopping at "contact" and "follow-up," we built out the rest of the consulting lifecycle in its own terms: engagements with defined scope, retainers with committed hours and renewal dates, stakeholders mapped within each client account, and invoicing tied directly to the engagement that generated it.
A retainer renewal in three weeks isn't a generic reminder — it's a specific object in Retainer with a term, a committed-hours number, and a renewal date attached, so the system can surface it on its own. The depth is in the vocabulary, not in extra clicks to get there.
Who Mimiran fits best
If you're a true solo practitioner — one person, a handful of ongoing relationships, and a need for something closer to a smart contact list than a practice-management system — Mimiran's minimal footprint is a legitimate advantage. There's real cost to running more software than you need, and Mimiran is explicitly designed to avoid that cost.
Who Retainer fits best
Retainer is built for consultants and boutique firms whose work is structured around actual retainers and multi-stakeholder engagements — where a client relationship isn't just a name you follow up with, but a scope, a set of committed hours, a renewal date, and often more than one person on the client side you need to track separately. If your practice has outgrown "keep it simple" and started needing "keep it organized by engagement," that's the gap Retainer is built to close.
The honest comparison
Both products reject the same thing: generic CRM complexity dressed up for sales teams. Mimiran answers that by removing weight. Retainer answers it by rebuilding the vocabulary from the ground up around how consulting engagements actually work — so the system stays simple to use while still understanding what a retainer, a renewal, or a stakeholder actually is. Neither approach is wrong; they're optimized for different practice sizes and different amounts of structure in the work.
If your engagements already run on retainers with real terms and renewal dates, it's worth seeing what that structure looks like in writing. The free Retainer Agreement Generator turns your fee, committed hours, and renewal terms into a ready-to-send agreement in the same language Retainer uses to track it afterward.
