43 - Team

Anabel Paksoy has been working with venture-backed founders since 2014.

Anabel grew up Quaker outside Boston, graduated from Penn, and moved west to build her operating career inside a string of hyper-growth technology companies, TURN (acquired by Amobee), TellApart (acquired by Twitter), and Opendoor (NASDAQ:OPEN) where she scaled the people team from 30 to 550 as one of the company's earliest People Operations leaders.

She started angel investing while still at Opendoor. Her first check went into The Assembly, a venture-backed community and workspace in San Francisco, and she eventually joined the founding team. There she started The Council, a group of female operators from companies like Stripe, Flexport, Cruise, and Slack and professional investors from firms like First Round and Susa Ventures learning to invest together. The through-line from people ops to investing felt obvious to her: pick the people before anything else is knowable.

She later co-founded The People Design House with Nathalie McGrath, a boutique advisory helping early-stage founders like those from Notion, Pave, Lattice, Uniswap, TRM Labs, and Ethos build high-performing teams. TPDH also worked with the portfolios of venture firms including USV, Susa Ventures, Serena Ventures, Redpoint, YC Growth, and Anthemis.

Her personal angel portfolio includes TRM Labs, Pave, and Newfront.

She met Dustin in March 2020, introduced by the founder of an angel investment. They started collaborating on community and co-investing immediately, and launched 43 together in 2021.

Anabel lives in San Francisco, where she can often be found electric bike riding with her husband and two young sons and spending weekends in West Marin eating oysters.

Dustin Dolginow has been investing at the earliest stage since 2010.

He started his career in venture when Jeff Fagnan hired him as an analyst at Atlas Venture in 2010. He was promoted in 2014 after leading investments in Unbounce and Spindle (acquired by Twitter) and helped launch Accomplice. He then sourced and co-led a seed stage investment in PillPack just before moving to San Francisco and launching a new $25M fund, Maiden Lane, in partnership with the AngelList team.

While at Maiden Lane, he collaborated with 150 different angel investors who led investments into 300+ startups. Together they built a portfolio that includes early investments in Notion, Vercel, Framer, Klaviyo, Carta, Side, Brave, Zipline, Arcadia, Hipcamp, HoneyBook, Cabify, Kiwi, Hologram, Stream, CodeSignal, Pipefy, WeFox, Ripio, Branch, Headout, Juniper Square, Rekki, Supply and many others. Studying such a broad portfolio, it became clear that the only thing that matters is finding product/market fit.

In 2018, Dustin stepped down from his Partner role at Accomplice to start writing first checks as a solo angel investor with the idea that it’s possible to pick founders that have the rare combination of tenacity, grit, curiosity and drive to find product/market fit before they build any product or have customers. He invested in two dozen startups, including Baseten and Roofr which both found product/market fit and reached scale.

Through an angel investment he met Anabel in 2020. They started co-investing casually before co-founding 43 in 2021.

Dustin graduated from Middlebury College with a B.A. in International Politics & Economics. He began his career in the investment banking division of Lehman Brothers in 2006 and was promoted from Analyst to Associate before being laid off when Barclays acquired the firm in late 2008. He took a brief sabbatical home to Kansas City to help his parents liquidate their family jewelry store, then returned to New York to start Social Swipe — a fintech startup inspired by what he had seen in Lehman's securitization group and his parents' use of customer payments data. He is originally from Kansas City and speaks Spanish.
