Rapaport names Yosi Botzer chief technology officer
The former Perion Network executive takes a company-wide artificial intelligence mandate. It extends across Rapaport's businesses, including the price list the natural diamond trade discounts against.
By Carat Capital
What changed
The price list gets a technologist. Rapaport has appointed Yosi Botzer, formerly chief technology officer of Perion Network, as its own chief technology officer. The mandate is company-wide and extends artificial intelligence across its businesses, including its price list.
What it means
- If you price against the list: The company says the initiative extends to the Rapaport Price List itself. It does not say what changes, when, or whether the methodology is affected.
- If you sell software to the trade: A pricing, news, trading and auction group has hired an ad-tech executive, not a diamond technologist. Ring Builder is named as already shipped.
- What this is not: A change to any published price. No figure, date or methodology statement accompanies the appointment.

An outsider to diamonds
The background is ad-tech. Botzer has more than 20 years building ad-tech and data platforms. He was chief technology officer of Nasdaq-listed Perion Network.
Five businesses, one strategy. At Perion he led technical strategy across five businesses the company had acquired. Earlier he built large-scale data systems at Datorama, later bought by Salesforce.
The remit is company-wide. He will oversee how Rapaport develops technology and runs its businesses. The products it offers the natural diamond trade are also in scope.

Notes on this table
There is no number in this story beyond the appointee's years of experience and the five businesses he covered at his previous employer, and that absence is the reason this article is short. No budget, no headcount, no timetable and no product roadmap is published. The one item in scope that carries weight for a reader is the Rapaport Price List, which is the reference most of the natural diamond trade discounts against, and the report says only that the initiative will extend to it. What that means in practice is not stated by the company and is not inferred here.
The list is in scope
The company names it. The company says the initiative will extend to the Rapaport Price List. The report calls that list its widely used diamond pricing tool.
One product has shipped. The company has already begun putting artificial intelligence into trade products. Its recently introduced Ring Builder lets retailers create bespoke ring designs while a customer shops.
Five lines of business. Rapaport operates businesses spanning diamond pricing, research, news, online trading and auctions, all of which the mandate covers.
What to watch
- When publishedAny methodology note attached to the price list. The list is named in scope and nothing about its construction has changed on this news.
- OngoingFurther product releases after Ring Builder, which is the only shipped example given.
- OngoingWhether a budget or headcount is disclosed. Neither accompanies the appointment.

What would change this call
The company saying the price list is not in scope. The one claim here that matters to a reader is that the artificial intelligence mandate reaches the Rapaport Price List, and it rests on a single trade report of a company announcement which this desk has not re-fetched from the company's own newsroom. Everything else is biography. If the list is out of scope, this article's only consequential sentence is wrong.
Why the price list is the part worth watching
The Rapaport Price List is a weekly sheet of asking prices by size, colour and clarity, and almost nobody in the natural diamond trade transacts at the number printed on it. What the trade does instead is quote a discount or a premium to it, so a stone is sold at minus twenty-eight back of list rather than at a dollar figure. That convention makes the list an index rather than a price, and it gives it a property most indices do not have: changing how it is built changes the stated terms of transactions already being negotiated against it, without anybody's price having moved. This is why an appointment with no budget and no timetable is still worth printing. The company has named the list as inside the scope of a company-wide technology mandate, and the person taking the mandate spent two decades building data platforms in advertising, an industry where pricing is set by automated auction rather than by a published sheet. None of that says the list will change. It says the group that publishes it has hired someone whose professional instinct is to automate a price, and has said the list is in his remit. The thing to watch is therefore not a product launch but a methodology note, because a change to how an index is computed is the one event here that would reprice goods rather than merely re-describe them.
Method
The appointment was read from JCK Online's Take 5 column, fetched in this run with a browser identity and saved as raw bytes: www.jckonline.com/editorial-article/jck-take-5-new-plumb-club-members/, 200, 114,249 bytes, in its section headed 'Rapaport Names Yosi Botzer CTO to Lead AI Push'. Greps against that saved copy before writing: 'Yosi Botzer' 2 hits, 'Perion' 2 hits. The publisher's feed, 200, 78,292 bytes, carries the column with its own pubDate of Thu, 15 Oct 2026 16:30:14 +0000. Rapaport's own feed, 200, 44,609 bytes, carries the company's announcement dated Thu, 15 Oct 2026 15:43:16 +0000 as 'Rapaport Appoints Yosi Botzer as CTO to Lead AI Transformation', which establishes that the company announced it and when. DISCLOSED LIMIT: the company's own release page was not fetched in this run, so the detail here is one trade report plus a feed headline, and no figure is taken from the feed. ARCHIVE: 'Botzer' returns 0 hits in Carat Capital's archive. The zero was checked against the schema first by printing a row of that file, which shows the fields slug, desk, date, kicker, lead, title, dek, byline, tags, body and sources, so a whole-record search is the right query and a name would be found in it if present. NEW, a first filing on this person; this paper has covered Rapaport's price list and its index repeatedly and has never covered its technology leadership.
