Acaboom

Acaboom is the market appraisal and proposal platform UK estate agents use to win more instructions. In this September 2026 catch up, founder Brian walks Simon Whale through three things Acaboom has shipped in the last few months. Behavioural Intelligence, which tells agents who to call and what is bothering them. Priority Prospects, which surfaces the sellers most likely to move. And the AI Concierge, a homeowner-facing assistant that answers questions on the proposal itself and weaves in the agent's own reasons to instruct. Killer stats from the interview: • 7% of market appraisals convert on the day (Reapit data, 350,000 valuations). 68% instruct in the four weeks that follow. • A proposal that never gets opened has a 12.5% win rate. One view lifts it to 14.5%, two views to 18%, three views roughly doubles the single-view number. • A pre-appointment view adds another 2% on top. • Acaboom-using agents average 98.5% sale-to-asking versus a market baseline of 97.5%, worth roughly £5,000 more on a £500k sale. • When homeowners engage with the AI Concierge, a high percentage go on to instruct. Engagement is the leading signal.
