Mobile CRM view builder for field sales reps

A field sales rep is standing in a parking lot between customer visits, trying to log a call and check the next account's history on their phone. The CRM's mobile app is a shrunken version of the desktop — same cluttered layout, same tiny fonts, same irrelevant fields. They give up and write it on a note to log later. Later never comes, and the CRM data rots.

Mobile is treated as an afterthought by most CRM vendors because the product decisions are made by people sitting at desks. The complaints here are direct: 'the mobile app needs to be optimized, concerning UI design mostly' and 'not as mobile friendly as it could be.' These aren't edge cases — field sales, account managers, and anyone customer-facing away from a desk are core CRM users, but they're not the persona the vendor designs for.

The deeper structural problem: building a genuinely good native mobile experience for a CRM is expensive and requires understanding the specific workflows of reps in motion — quick log, fast lookup, one-tap next step. That's a different design job than the desktop, and vendors don't have bandwidth to do it twice. So mobile stays broken.

This is a real business because the failure mode has a concrete cost. When reps don't log on mobile, CRM data falls behind. When data falls behind, pipeline forecasts are wrong. When forecasts are wrong, management loses trust in the CRM entirely and starts asking for manual spreadsheet updates — which costs everyone more time than the original problem. That cascade recurs every quarter at every company with a field team.

What to build

Build a native iOS and Android app that connects to existing CRM APIs (starting with one or two with well-documented REST APIs), presents only the fields and actions a rep configures as relevant, and lets managers define what 'log a visit' looks like in three taps or fewer.

Where to start

Target one vertical — medical device or pharma sales reps are legally required to log visits accurately, which creates compliance pressure that makes paying for a better mobile logging experience an easy justification.

The hard part

CRM API rate limits and authentication restrictions vary wildly, and some mid-market CRMs have underdocumented or unstable APIs — the first integration could take three times longer than estimated, leaving you with one CRM supported and a small addressable market until you expand.

How it makes money

Per-seat monthly fee paid by the sales manager or ops team; priced below the cost of one hour of a rep's time per month to make the ROI obvious.
